Description

La présente invention concerne les dispositifs d'accouplement entre un ensemble de train de tubes et de train tiges et les moyens de commande d'entraînement en rotation de ces trains comme ceux qui sont couramment utilisés dans le domaine du forage de puits de profondeur pouvant atteindre quelques centaines de mètres.The present invention relates to the coupling devices between a set of tubes and drill string and the control means for driving these trains in rotation, such as those commonly used in the field of deep well drilling which can reach a few hundred meters.

Il est connu actuellement, notamment par le US-A-5 682 956 et le EP-A-1 936 109 , pour la réalisation d'un puits dans un sol donné et en association avec une machine foreuse, un système comportant un train de tiges, un outil de forage monté en coopération avec le train de tiges, un train de tubes entourant le train de tiges, et des moyens pour entraîner en rotation les deux trains, ces derniers moyens étant agencés pour entraîner en rotation le train de tubes dans un premier sens et le train de tiges, dans le train de tubes, dans un second sens opposé au premier.It is currently known, in particular by US-A-5,682,956 and the EP-A-1,936,109 , for producing a well in a given soil and in association with a drilling machine, a system comprising a drill string, a drilling tool mounted in cooperation with the drill string, a tube train surrounding the drill string , and means for rotating the two trains, the latter means being arranged to rotate the tube train in a first direction and the drill string in the tube train in a second direction opposite to the first.

Les moyens pour entraîner en rotation les deux trains comportent très schématiquement des moyens moteurs et des moyens de couplage pour relier la sortie des moyens moteurs respectivement aux deux trains de tiges et de tubes.The means for rotating the two trains comprise schematically motor means and coupling means for connecting the output of the motor means respectively to the two sets of rods and tubes.

Or, avec ce type de système de forage de puits, se pose un problème lorsque la profondeur du puits à creuser peut aller jusqu'à une ou plusieurs centaines de mètres. Dans ce cas, il est bien évident qu'il est impossible que les deux trains de tiges et de tubes soient d'un seul tenant. Les tiges et tubes qui sont alors utilisés ne font que quelques mètres de longueur et, au fur et à mesure que le puits est creusé, il faut découpler les moyens d'entraînement en rotation et les deux trains de tiges et de tubes, ajouter un nouveau couple tige-tube, reprendre le creusement du puits, et ainsi de suite jusqu'à ce que le puits ait atteint la profondeur voulue.However, with this type of well drilling system, there is a problem when the depth of the well to be digged can be up to one or several hundred meters. In this case, it is obvious that it is impossible for the two sets of rods and tubes to be in one piece. The rods and tubes which are then used are only a few meters in length and, as the well is dug, it is necessary to decouple the rotating drive means and the two trains of rods and tubes, to add a new stem-tube pair, resume digging the well, and so on until the well has reached the desired depth.

Or, comme les tiges sont mises en rotation à l'intérieur des tubes, se pose alors le problème de leur désaccouplement avec les moyens qui les entraînent en rotation. En effet, il est impensable de procéder, chaque fois, à l'enlèvement des tubes pour avoir accès aux tiges et/ou manipuler les deux trains l'un par rapport à l'autre pour ajouter un nouveau couple tige-tube.However, since the rods are rotated inside the tubes, the problem of their uncoupling with the means rotate. Indeed, it is unthinkable to proceed, each time, the removal of the tubes to access the rods and / or manipulate the two trains relative to each other to add a new stem-tube pair.

Il a donc été mis au point des systèmes d'accouplement entre un ensemble de train de tubes et de train tiges et les moyens de commande en entraînement en rotation de ces trains pour faciliter l'accès aux tiges sans être obligé de démonter tout le train de tubes en fonctionnement dans la partie de puits déjà creusé et/ou de le manipuler d'une façon spéciale.It has therefore been developed coupling systems between a set of tubes and drill string and control means in rotational drive of these trains to facilitate access to the rods without the need to disassemble the entire train of tubes in operation in the well part already dug and / or handle it in a special way.

Notamment, le Demandeur a déjà réalisé un dispositif d'accouplement entre un ensemble de train de tubes et de train tiges et les moyens de commande en entraînement en rotation d'au moins l'un des deux trains, qui permette de résoudre ce problème de façon relativement rapide et aisée pour les techniciens foreurs.In particular, the Applicant has already made a coupling device between a set of tubes and drill string and the control means in rotational drive of at least one of the two trains, which makes it possible to solve this problem of relatively fast and easy way for driller technicians.

Cependant, la présente invention a pour but de réaliser un dispositif d'accouplement qui soit plus fiable, plus facile à utiliser que les dispositifs d'accouplement selon les précédentes réalisations, notamment le dispositif d'accouplement du Demandeur évoqué, en simplifiant les manipulations sur les deux trains de tiges et de tubes.However, the object of the present invention is to provide a coupling device which is more reliable and easier to use than the coupling devices according to the previous embodiments, in particular the coupling device of the evoked Applicant, by simplifying the manipulations on the two sets of rods and tubes.

Plus précisément, la présente invention a pour objet un dispositif d'accouplement entre un ensemble de train de tubes et de train tiges, et des moyens de commande en entraînement en rotation d'au moins l'un des deux trains lorsque le train de tiges est apte à être monté en rotation dans le train de tubes, selon la revendication 1 annexée.More specifically, the present invention relates to a coupling device between a set of tubes and drill string, and control means for driving in rotation of at least one of the two trains when the drill string is adapted to be rotatably mounted in the tube train, according to the appended claim 1.

La présente invention concerne, par référence aux figures annexées, un dispositif d'accouplement entre, d'une part un ensemble de train de tubes Ttu et de train tiges Tti, et d'autre part les moyens de commande Mro en entraînement en rotation d'au moins l'un des deux trains lorsque le train de tiges est apte à être monté en rotation dans le train de tubes, sachant que, de façon avantageuse, ces moyens de commande Mro en entraînement en rotation permettent d'entraîner le train de tiges dans un sens et le train de tubes dans le sens opposé, et ce, de façon connue, pour une réalisation plus aisée du puits.The present invention relates, with reference to the appended figures, to a coupling device between, on the one hand, a set of tubes Ttu and of rods Tti, and, on the other hand, the control means Mro, in rotation drive. at least one of the two trains when the drill string is adapted to be mounted in rotation in the tube train, knowing that, advantageously, these rotational drive means Mro drive the train of rods in one direction and the train of tubes in the opposite direction, and this, in a known manner, for an easier realization of the well.

Le dispositif d'accouplement comporte une portion de tube cylindrique 10 définie entre deux première 11 et seconde 12 extrémités, cette portion de tube 10 ayant, selon une caractéristique de l'invention, une section transversale intérieure au moins égale à celle des tiges du train de tiges et une section transversale extérieure de forme polygonale, comme plus particulièrement visible sur les figures 1, 2 et 4.The coupling device comprises a portion of cylindrical tube 10 defined between two first 11 and second 12 ends, this portion of tube 10 having, according to a feature of the invention, an internal cross section at least equal to that of the rods of the train rods and an outer cross section of polygonal shape, as more particularly visible on the Figures 1, 2 and 4 .

Le dispositif d'accouplement comporte aussi des moyens 20 pour relier la première extrémité 11 de la portion de tube cylindrique 10 avec les moyens de commande en rotation Mro. Ces moyens de liaison 20 sont du domaine des personnes du métier qui sauront les réaliser en fonction de la nature des moyens de commande en rotation Mro. Ils seront donc représentés schématiquement sur les figures par une bride avec des moyens de boulonnage, mais pas plus amplement décrits.The coupling device also comprises means 20 for connecting the first end 11 of the cylindrical tube portion 10 with the rotational control means Mro. These connecting means 20 are in the field of those skilled in the art who will be able to achieve them depending on the nature of the rotation control means Mro. They will be schematically represented in the figures by a flange with bolting means, but not more fully described.

Est aussi prévu un manchon 30 défini entre deux première 31 et seconde 32 extrémités et comportant une percée traversante 33. Cette percée traversante comporte deux ouvertures situées respectivement aux première et seconde extrémités 31, 32 du manchon 30, par exemple dans leur plan perpendiculaire à l'axe longitudinal 34 du manchon, et, selon une caractéristique importante de l'invention, présente une section transversale sensiblement complémentaire de la section transversale extérieure de la portion de tube 10 de façon que cette portion de tube plonge, par sa seconde extrémité 12, dans la percée traversante 33 en passant par son ouverture située au niveau de la première extrémité 31 du manchon 30 et de façon que le manchon 30 soit apte à coulisser sur la portion de tube 10, sans subir de rotation autour de son axe longitudinal 34 par rapport à la portion de tube 10, pour être apte à prendre au moins deux première et seconde positions P1, P2 représentées sur la figure 1, respectivement en traits pleins et en traits interrompus.Is also provided a sleeve 30 defined between two first 31 and second 32 ends and having a through-hole 33. This through-hole comprises two openings located respectively at the first and second ends 31, 32 of the sleeve 30, for example in their plane perpendicular to the longitudinal axis 34 of the sleeve, and, according to an important characteristic of the invention, has a cross section substantially complementary to the external cross section of the tube portion 10 so that this portion of tube plunges, by its second end 12, in the through-hole 33 passing through its opening located at the first end 31 of the sleeve 30 and so that the sleeve 30 is able to slide on the tube portion 10, without being rotated about its longitudinal axis 34 by relative to the portion of tube 10, to be able to take at least two first and second positions P1, P2 represented on the figure 1 , respectively in solid lines and in broken lines.

La première position P1 du manchon 30 est celle dans laquelle une partie 16 de la portion de tube 10 plonge dans la percée traversante 33 de façon que la seconde extrémité 12 de cette portion de tube soit située à une distance non nulle de la seconde extrémité 32 du manchon. En d'autres termes, la longueur de cette partie 16 de la portion de tube qui plonge dans la percée traversante est nettement inférieure à la longueur de cette percée traversante.The first position P1 of the sleeve 30 is that in which a portion 16 of the tube portion 10 is immersed in the through bore 33 so that the second end 12 of this tube portion is located at a non-zero distance from the second end 32. of the sleeve. In other words, the length of this portion 16 of the portion of tube that plunges into the through-hole is significantly less than the length of this through-hole.

Quant à la seconde position P2 du manchon, elle est celle dans laquelle la valeur de la distance séparant la première extrémité 31 du manchon et la première extrémité 11 de la portion de tube 10 est inférieure à la valeur de cette même distance quand le manchon est dans sa première position P1.As for the second position P2 of the sleeve, it is the one in which the value of the distance separating the first end 31 of the sleeve and the first end 11 of the tube portion 10 is less than the value of this same distance when the sleeve is in its first position P1.

Le dispositif d'accouplement comporte en outre un embout tubulaire 40 défini entre deux première 41 et seconde 42 extrémités, et dont la section transversale intérieure est au moins égale à celle des tiges du train de tiges.The coupling device further comprises a tubular nozzle 40 defined between two first 41 and second 42 ends, and whose internal cross section is at least equal to that of the rods of the drill string.

En outre, la première extrémité 41 de cet embout 40 comporte une partie d'extrémité 43 d'une section transversale extérieure sensiblement complémentaire de la section transversale de la percée traversante 33 du manchon 30, c'est-à-dire présentant la même (ou sensiblement la même) forme polygonale, de façon à être apte à s'enficher dans cette percée traversante 33 en passant par son ouverture située au niveau de la seconde extrémité 32 du manchon 30.In addition, the first end 41 of this endpiece 40 has an end portion 43 of an outer cross section substantially complementary to the cross section of the through-hole 33 of the sleeve 30, that is to say having the same (FIG. or substantially the same) polygonal shape, so as to be able to be plugged into the through hole 33 through its opening located at the second end 32 of the sleeve 30.

La seconde extrémité 42 de l'embout 40 comporte des moyens 44 pour la relier à une extrémité du train de tubes Ttu. Ces moyens de liaison 44 peuvent être de différentes natures, selon le type de liaison entre les tubes constituant le train de tubes. A titre illustratif, ces moyens de liaison 44 ont été représentés sur les figures 4 et 5 par un filetage car, dans le domaine notamment du forage, la jonction des tubes s'effectue le plus couramment par vissage.The second end 42 of the nozzle 40 has means 44 for connecting it to one end of the tube train Ttu. These connecting means 44 may be of different types, depending on the type of connection between the tubes constituting the tube train. By way of illustration, these connection means 44 have been represented on the Figures 4 and 5 by a thread because, in the field including drilling, the junction of the tubes is most commonly made by screwing.

De façon préférentielle, comme illustré, la partie d'extrémité 43 et la seconde extrémité 42 de l'embout tubulaire 40 sont séparées par une couronne ou analogue 45 qui peut constituer avantageusement une butée pour limiter notamment l'enfichage de la partie d'extrémité 43 dans la percée traversante 33.Preferably, as illustrated, the end portion 43 and the second end 42 of the tubular end piece 40 are separated by a ring or the like 45 which may advantageously constitute a stop to limit in particular the insertion of the end portion 43 in the through breakthrough 33.

Selon une caractéristique particulièrement préférentielle de l'invention, la longueur du manchon 30, prise entre ses première et seconde extrémités 31, 32, est au plus égale à la longueur de la portion de tube 10, avantageusement sensiblement de la même longueur.According to a particularly preferred characteristic of the invention, the length of the sleeve 30, taken between its first and second ends 31, 32, is at most equal to the length of the tube portion 10, advantageously substantially of the same length.

Selon une autre caractéristique de l'invention, le dispositif d'accouplement comporte en outre des moyens de blocage temporaire commandables 50 pour bloquer le manchon 30 sur la portion de tube 10 respectivement dans ses première et seconde positions P1, P2. Selon une réalisation préférentielle et avantageuse, ces moyens de blocage temporaire commandables 50 sont constitués, comme représenté sur presque toutes les figures, de deux encoches 51, 52 réalisées dans la paroi latérale extérieure de la portion de tube 10 suivant un axe faisant un angle non nul par rapport à l'axe longitudinal 15 de cette portion de tube, de préférence un angle droit, et d'une goupille 54 montée en translation par rapport au manchon dans un trou 55 sécant avec la percée traversante 33, plus particulièrement visible sur les figures 1, 2 et 3, de façon qu'elle soit apte à plonger dans l'une ou l'autre des deux encoches 51, 52 selon que le manchon se trouve dans l'une ou l'autre de ses première et seconde positions P1, P2.According to another characteristic of the invention, the coupling device further comprises controllable temporary blocking means 50 for locking the sleeve 30 on the tube portion 10 respectively in its first and second positions P1, P2. According to a preferred and advantageous embodiment, these controllable temporary blocking means 50 consist, as shown in almost all the figures, of two notches 51, 52 made in the outer lateral wall of the tube portion 10 along an axis forming an angle zero relative to the longitudinal axis 15 of this tube portion, preferably a right angle, and a pin 54 mounted in translation relative to the sleeve in a hole 55 secant with the through-hole 33, more particularly visible on the Figures 1, 2 and 3 , so that it is able to plunge into one or the other of the two notches 51, 52 according to whether the sleeve is in one or other of its first and second positions P1, P2.

De façon avantageuse, le dispositif d'accouplement comporte en outre des moyens 56, par exemple un ressort ou analogue, pour appliquer une tension élastique sur la goupille 54 et tendre à la maintenir constamment dans l'encoche 51, 52 dans laquelle elle est positionnée.Advantageously, the coupling device further comprises means 56, for example a spring or the like, for applying an elastic tension on the pin 54 and tending to maintain it constantly in the notch 51, 52 in which it is positioned .

Selon une autre caractéristique importante de l'invention, le dispositif d'accouplement comporte en outre des moyens de blocage-déblocage réversibles 60, figures 4 à 6, de l'embout tubulaire 40 avec le manchon 30.According to another important characteristic of the invention, the coupling device further comprises reversible locking-unlocking means 60, Figures 4 to 6 , of the tubular end piece 40 with the sleeve 30.

Selon une réalisation possible, ces moyens de blocage-déblocage réversibles 60 de l'embout tubulaire 40 avec le manchon 30 sont constitués par au moins deux orifices 61, 62, ou assimilables, réalisés respectivement dans la seconde extrémité 32 du manchon 30 et dans l'embout tubulaire 40, et par une épingle 63 à au moins deux branches 64, 65.According to one possible embodiment, these reversible locking-unlocking means 60 of the tubular endpiece 40 with the sleeve 30 are constituted by at least two orifices 61, 62, or similar, made respectively in the second end 32 of the sleeve 30 and in the tubular end piece 40, and by a pin 63 with at least two branches 64, 65.

Dans le mode de réalisation illustré sur les figures 4 à 6, l'orifice 62 est un orifice relatif constitué par l'espace situé derrière une couronne 45 qui appartient à l'embout tubulaire 40, par rapport au manchon 30.In the embodiment illustrated on the Figures 4 to 6 , the orifice 62 is a relative orifice constituted by the space located behind a ring 45 which belongs to the tubular tip 40, with respect to the sleeve 30.

Quant aux deux branches 64, 65 de l'épingle 63, elles sont aptes à s'enficher respectivement dans les deux orifices 61, 62 définis ci-dessus pour solidariser l'embout tubulaire 40 avec le manchon 30 quand la partie d'extrémité 43 est enfichée dans la percée traversante 33 par l'ouverture de cette dernière située au niveau de la seconde extrémité 32 du manchon 30.As for the two branches 64, 65 of the pin 63, they are able to be plugged respectively into the two orifices 61, 62 defined above for securing the tubular nozzle 40 with the sleeve 30 when the part end 43 is plugged into the through hole 33 through the opening of the latter located at the second end 32 of the sleeve 30.

Selon une autre caractéristique avantageuse de l'invention, le dispositif d'accouplement comporte en outre au moins une lumière 70 réalisée dans la paroi 71 du manchon 30, un touret 72 entourant de façon étanche le manchon 30 pour former, avec la paroi extérieure de ce manchon 30, une chambre sensiblement annulaire 73 dans laquelle débouche la lumière 70, et des moyens d'entrée 74 montés en coopération avec le touret 72 et débouchant dans la chambre sensiblement annulaire 73 permettant, si nécessaire, l'introduction et/ou l'élimination d'un fluide entre le train de tubes et le train de tiges. Cette technique est du domaine des personnes du métier et ne sera donc pas plus amplement développée ici, dans l'unique souci de ne pas alourdir la présente description.According to another advantageous characteristic of the invention, the coupling device further comprises at least one lumen 70 made in the wall 71 of the sleeve 30, a drum 72 sealingly surrounding the sleeve 30 to form, with the outer wall of this sleeve 30, a substantially annular chamber 73 into which the light 70 opens, and input means 74 mounted in cooperation with the drum 72 and opening into the substantially annular chamber 73 allowing, if necessary, the introduction and / or the elimination of a fluid between the tube train and the drill string. This technique is in the field of those skilled in the art and will therefore not be further developed here, for the sole purpose of not weighing down the present description.

Le dispositif d'accouplement selon l'invention dont la structure est décrite ci-dessus s'utilise de la façon suivante :

  • On suppose tout d'abord que le dispositif est dans une configuration comme celle qui est illustrée sur la figure 6, à savoir : la première tige du train de tiges Tti est connectée de façon connue, par exemple par vissage ou analogue, aux moyens d'entraînement en rotation Mor dans un premier sens, le premier tube du train de tubes Ttu est par exemple vissé sur l'extrémité 42 de l'embout tubulaire 40 qui est enfiché, par sa partie d'extrémité 43, dans la percée traversante 33 du manchon 30, la portion de tube 10 est enfichée, par sa partie 16, dans cette percée traversante de façon que sa seconde extrémité 12 soit éloignée de la première extrémité 41 de l'embout tubulaire 40, pour délimiter avec elle l'espace libre Esp défini ci-avant.
The coupling device according to the invention, the structure of which is described above, is used as follows:
  • It is assumed first of all that the device is in a configuration such as that illustrated on the figure 6 , namely: the first rod of the drill string Tti is connected in known manner, for example by screwing or the like, to the Mor rotation drive means in a first direction, the first tube of the Ttu tube train is for example screwed on the end 42 of the tubular end piece 40 which is plugged, by its end portion 43, into the through-hole 33 of the sleeve 30, the portion of tube 10 is plugged, by its part 16, into this through-hole of so that its second end 12 is remote from the first end 41 of the tubular nozzle 40, to delimit with it the free space Esp defined above.

La première extrémité 11 de la portion de tube 10, via les moyens 20, est reliée aux moyens d'entraînement en rotation Mor dans le sens opposé à celui du train de tiges Tti.The first end 11 of the tube portion 10, via the means 20, is connected to the rotation drive means Mor in the opposite direction to that of the drill string Tti.

L'embout tubulaire 40 est solidaire en translation du manchon 30 au moyen de l'épingle 63. Le manchon 30 et l'embout tubulaire 40 sont solidaires en rotation, à cause des formes polygonales complémentaires de la paroi extérieure de la première partie 43 de cet embout 40 et de la percée traversante 33.The tubular endpiece 40 is integral in translation with the sleeve 30 by means of the pin 63. The sleeve 30 and the tubular endpiece 40 are integral in rotation, because of the complementary polygonal shapes of the outer wall of the first portion 43 of this nozzle 40 and the through-hole 33.

Quant au manchon 30, il est solidaire en translation avec la portion de tube 10 dans sa première position P1 au moyen de la goupille 54 plongeant dans l'encoche 52, et solidaire en rotation avec cette portion de tube 10 à cause des formes polygonales complémentaires de la paroi extérieure de la portion de tube 10 et de la percée traversante 33.As for the sleeve 30, it is integral in translation with the tube portion 10 in its first position P1 by means of the pin 54 immersed in the notch 52, and integral in rotation with this portion of tube 10 because of complementary polygonal shapes the outer wall of the tube portion 10 and the through-hole 33.

De cette façon, les deux trains de tiges et de tubes peuvent être entraînés en rotation en sens inverse l'un par rapport à l'autre et le forage du puits peut de façon connue commencer. Les moyens d'entraînement en rotation Mor descendent vers le sol au fur et à mesure que se creuse le puits.In this way, the two sets of rods and tubes can be rotated in opposite directions with respect to each other and drilling of the well can in a known manner begin. The rotation drive means Mor descend towards the ground as the well is being dug.

Lorsque le dispositif d'accouplement selon l'invention est arrivé, en descendant, sensiblement au niveau du sol à partir duquel est creusé le puits, la rotation des deux trains de tiges et de tubes est arrêtée.When the coupling device according to the invention has come down, substantially at ground level from which the well is dug, the rotation of the two sets of rods and tubes is stopped.

Le technicien responsable du creusement du puits procède alors de la façon suivante :

  • Il enlève l'épingle 63 pour désolidariser l'embout tubulaire 40 et le manchon 30, puis tire sur la goupille 54 à l'encontre du ressort 56 et soulève le manchon 30 pour le faire coulisser sur la portion de tube 10, de sa première position P1 dans laquelle il se trouve jusqu'à sa seconde position P2. Il bloque alors le manchon 30 sur la portion de tube 10 en laissant glisser la goupille 54 dans l'encoche 51, libérant de ce fait tout l'espace libre Esp entre les extrémités 12 et 41 définies ci-avant.
  • Il peut alors dévisser la première tige du train de tiges Tti en passant l'outil de dévissage par cet espace Esp. Cette première tige du train Tti va en fait rester en place puisque reposant sur le fond du puits en cours de forage via éventuellement l'outil de forage Out, figure 6. Il procède aussi au dévissage de l'embout tubulaire 40 du premier tube qui, lui aussi, va rester en position en reposant sur le fond du puits en cours de creusement.
The technician responsible for digging the well then proceeds as follows:
  • It removes the pin 63 to separate the tubular tip 40 and the sleeve 30, then pulls the pin 54 against the spring 56 and lifts the sleeve 30 to slide on the tube portion 10, its first position P1 in which it is to its second position P2. It then blocks the sleeve 30 on the tube portion 10 by sliding the pin 54 in the notch 51, thereby freeing all the free space Esp between the ends 12 and 41 defined above.
  • He can then unscrew the first rod of the drill string Tti by passing the unscrewing tool by this space Esp. This first rod of the train Tti will actually remain in place since resting on the bottom of the well being drilled, possibly via the drill tool Out, figure 6 . It also unscrews the tubular tip 40 of the first tube which, too, will remain in position while resting on the bottom of the well being digged.

Ensuite, il remonte les moyens d'entraînement en rotation Mor de la valeur de la longueur d'un couple tige-tube. Dans ce mouvement, sont également remontés la portion de tube 10 et le manchon 30 dans sa seconde position P2. Il peut alors ajouter, par exemple par vissage, une seconde tige à la première tige qui repose sur le fond du puits, ainsi qu'un second tube en le vissant sur le premier, en ayant soin de visser l'embout tubulaire 40 sur l'extrémité haute de ce second tube.Then, it raises the rotation drive means Mor by the value of the length of a rod-tube pair. In this movement, are also reassembled the tube portion 10 and the sleeve 30 in its second position P2. It can then add, for example by screwing, a second rod to the first rod that rests on the bottom of the well, and a second tube by screwing it on the first, taking care to screw the tubular tip 40 on the high end of this second tube.

Il solidarise alors l'extrémité haute de la seconde tige avec les moyens d'entraînement en rotation qui avaient été libérés comme mentionné ci-avant, libère la goupille 54 de l'encoche 51, amène le manchon 30 de sa seconde position P2 à sa première position P1, l'ouverture de la percée traversante 33 située au niveau de la seconde extrémité 32 du manchon 30 venant se placer sur la partie d'extrémité à section polygonale 43 jusqu'à buter contre la couronne 45 définie précédemment. La goupille 54 vient d'elle même se loger dans l'encoche 52, et les deux trains de tiges et de tubes sont à nouveau solidaires des moyens d'entraînement en rotation Mor.He then secures the upper end of the second rod with the rotational drive means which had been released as mentioned above, releases the pin 54 from the notch 51, brings the sleeve 30 of its second position P2 to its first position P1, the opening of the through-hole 33 located at the second end 32 of the sleeve 30 to be placed on the polygonal section end portion 43 to abut against the ring 45 defined above. The pin 54 is itself housed in the notch 52, and the two sets of rods and tubes are again secured to the rotation drive means Mor.

Le forage peut alors recommencer. Tous les efforts en rotation notamment sur les tubes sont transmis via la portion de tube 10, le manchon 30 et la partie d'extrémité 43 de l'embout 40, par des sections polygonales et non pas par des moyens de blocage comme des goupilles ou analogues comme dans les dispositifs selon l'art antérieur.The drilling can then start again. All the efforts in rotation, in particular on the tubes, are transmitted via the tube portion 10, the sleeve 30 and the end portion 43 of the end piece 40, by polygonal sections and not by locking means such as pins or analogous as in the devices according to the prior art.

Il est à remarquer que l'épingle 63 peut être remise en place, ou pas, après l'ajout du deuxième couple tige-tube, car le train de tubes précédent repose sur le sol et l'emmanchement à section polygonale de la partie d'extrémité 43 de l'embout tubulaire 40 dans la percée traversante 33 est suffisant pour entraîner la rotation du train de tubes en toute sécurité.It should be noted that the pin 63 can be put back in place, or not, after the addition of the second stem-tube pair, since the preceding tube set rests on the ground and the polygonal section fitting of the part of end 43 of the tubular nozzle 40 in the through-hole 33 is sufficient to cause the rotation of the tube string safely.
