Description
La présente invention concerne un raccord coupe-câble pouvant être incorporé à une conduite dans laquelle est engagé un câble, en vue d'opérations de forage, de production, de diagraphie ou d'interventions dans des puits et permettant, en cas de nécessité, le sectionnement du câble au niveau du raccord.The present invention relates to a cable cutter connector which can be incorporated into a pipe in which a cable is engaged, for drilling, production, logging or well operations and allowing, if necessary, cutting the cable at the connector.
L'art antérieur peut être illustré par les brevets américains US-A-1.610.699, US-A-1.776.026, US-A-3.661.207, US-A-4.160.478 et US-A-4.427.059.The prior art can be illustrated by American patents US-A-1,610,699, US-A-1,776,026, US-A-3,661.207, US-A-4,160,478 and US-A-4,427,059 .
Le raccord coupe-câble selon la présente l'invention est notamment utilisable dans un train de tiges de forage comprenant un raccord à fenêtre latérale pour le passage d'un câble de l'intérieur vers l'extérieur des tiges, avec étanchéité hydraulique autour du câble.The cable cutter connection according to the present invention is particularly usable in a drill string comprising a side window connection for the passage of a cable from the inside to the outside of the rods, with hydraulic sealing around the cable.
Les reccords àfenêtre latérale (généralement désignés par "Side entry subs" dans l'industrie pétrolière) sont bien connus des spécialistes des forages pétroliers. Un tel dispositif est, par exemple, décrit dans le brevet britannique 2.135.719.Side window fittings (generally referred to as "side entry subs" in the petroleum industry) are well known to specialists in petroleum drilling. Such a device is, for example, described in British patent 2,135,719.
Un raccord à fenêtre latérale est, par exemple, utilisé dans la technique décrite dans le brevet français 2.501.777 (EN. 81/05.271) et ses deux premières additions EN. 82/03.317 et EN. 84/08.369.A side window fitting is, for example, used in the technique described in French patent 2,501,777 (EN. 81 / 05.271) and its first two additions EN. 82 / 03.317 and EN. 84 / 08.369.
Suivant cette technique, permettant d'effectuer des diagraphies ou interventions dans des puits horizontaux ou fortement inclinés, une sonde de diagraphie ou un outil d'intervention est initialement fixé à la partie inférieure d'un train de tiges qui est descendu dans le puits au fur et à mesure de sa constitution.According to this technique, making it possible to carry out logs or interventions in horizontal or strongly inclined wells, a logging probe or an intervention tool is initially fixed to the lower part of a drill string which is lowered into the well at as it was created.
On fait ensuite descendre à l'intérieur des tiges (par gravité et par pompage) un câble électrique muni d'un connecteur lesté (le connecteur est surmonté d'une barre de charge) qui vient se raccorder un connecteur complémentaire fixé au sommet de la sonde (ou de l'outil). Dans la portion du train de tiges correspondant à la partie verticale ou faiblement inclinée du puits, un raccord à fenêtre latérale fait passer le câble de l'intérieur vers l'extérieur des tiges.An electrical cable fitted with a weighted connector (the connector is surmounted by a load bar) is then lowered inside the rods (by gravity and by pumping) which is connected to a complementary connector fixed to the top of the probe (or tool). In the portion of the drill string corresponding to the vertical or slightly inclined part of the well, a side window fitting passes the cable from the interior to the exterior of the rods.
L'enregistrement de la mesure (ou l'intervention dans le puits) est effectué en déplaçant l'ensemble du train de tiges depuis la surface.The measurement recording (or intervention in the well) is carried out by moving the entire drill string from the surface.
Les équipements actuels avec raccord fenêtre latérale posent cependant un problème en cas de coincement du train de tiges dans le puits:
- En effet, la présence du câble électrique contenu à l'intérieur des tiges dans la partie comprise entre le raccord à fenêtre latrale et la barre de charge ne permet pas d'effectuer des interventions visant à décoincer le train de tiges.
- Indeed, the presence of the electric cable contained inside the rods in the part between the side window connection and the load bar does not allow interventions to loosen the string of rods.
Ces opérations ou interventions de décoincement sont, par exemple, l'introduction dans la tige, depuis la surface, d'outils spécialisés devant être descendus au moyen d'un câble jusqu'à la zone (qui est généralement située sous le raccord à entrée latérale) qui comporte les tiges coincées par la formation.These loosening operations or interventions are, for example, the introduction into the rod, from the surface, of specialized tools to be lowered by means of a cable to the area (which is generally located under the inlet fitting lateral) which includes the stems trapped by the formation.
Ces outils spécialisés peuvent, par exemple, être un explosif qui permet le dévissage de la tige coincée.These specialized tools can, for example, be an explosive which allows the unscrewing of the stuck rod.
Par ailleurs, la présence du câble à l'extérieur du train de tiges, au-dessus du raccord à fenêtre latérale, limite les possibilités de rotation du train de tiges.Furthermore, the presence of the cable outside the drill string, above the side window fitting, limits the possibilities of rotation of the drill string.
Un objet essentiel de l'invention est de permettre, dans un équipement du type indiqué ci-dessus, le sectionnement du câble juste au-dessus de la barre de charge.An essential object of the invention is to allow, in equipment of the type indicated above, the cutting of the cable just above the load bar.
La portion de câble située au-dessus de la barre de charge peut être alors remontée en surface, tandis que la barre de charge tombe par gravité à l'intérieur des tiges.The portion of cable located above the load bar can then be raised to the surface, while the load bar falls by gravity inside the rods.
Elle peut ensuite, si nécessaire, être déplacée par pompage jusqu'à l'extrémité supérieure du train de tiges.It can then, if necessary, be moved by pumping to the upper end of the drill string.
L'invention est également applicable dans le cas d'une éruption de puits pétrolier, lorsque le train de tiges comporte un raccord à entrée latérale situé sous la table. de rotation, ce raccord servant au passage d'un câble.The invention is also applicable in the case of an oil well blowout, when the drill string includes a side entry fitting located under the table. of rotation, this connector serving for the passage of a cable.
Il est en effet nécessaire dans ce cas de pouvoir remonter le câble situé à l'extérieur du train de tiges, au-dessus du raccord à fenêtre latérale, afin de pouvoir commander depuis la surface la fermeture du bloc obturateur de sécurité (B.O.P.) autour des tiges. Dans cette application, l'invention vise à permettre le sectionnement du câble au voisinage du raccord à entrée latérale, permettant de remonter la portion de câble située au-dessus de ce raccord avant de fermer les mâchoires du bloc obturateur de sécurité autour des tiges.It is indeed necessary in this case to be able to reassemble the cable located outside the drill string, above the fitting with side window, in order to be able to control from the surface the closing of the safety shutter block (BOP) around stems. In this application, the invention aims to allow the cable to be cut in the vicinity of the connector with lateral entry, making it possible to reassemble the portion of cable located above this connector before closing the jaws of the safety shutter block around the rods.
Les objectifs indiqués ci-dessus peuvent être atteints selon l'invention, avec un raccord coupe-câble pouvant être incorporé à une conduite dans laquelle est engagé un câble, en vue d'opérations de forage, de production, de diagraphie ou d'interventions dans des puits et permettant, en cas de nécessité, le sectionnement du câble au niveau du raccord, ce raccord comportant un corps tubulaire dans lequel peut coulisser une chemise, caractérisé en ce que la paroi latérale de ladite chemise tubulaire présente une ouverture dans laquelle est engagé un organe de sectionnement du câble et en ce que ladite chemise est déplaçable d'une première position offrant un libre passage axial au câble, à une seconde position dans laquelle un épaulement interne de ladite chemise appuie le câble contre ledit organe de sectionnement.The objectives indicated above can be achieved according to the invention, with a cable cutter fitting which can be incorporated into a pipe in which a cable is engaged, for drilling, production, logging or intervention operations. in wells and allowing, if necessary, the cutting of the cable at the connection, this connection comprising a tubular body in which a jacket can slide, characterized in that the side wall of said tubular jacket has an opening in which is engaged a cable sectioning member and in that said jacket is movable from a first position offering a free axial passage to the cable, to a second position in which an internal shoulder of said jacket presses the cable against said sectioning member.
Ledit organe de sectionnement du câble peut comporter un doigt pivotant articulé dans un logement de la paroi interne du corps tubulaire.Said cable cutting member may comprise a pivoting finger articulated in a housing of the internal wall of the tubular body.
L'invention concerne plus particulièrement un raccord coupe-câble tel que défini ci-dessus dans lequel lesdites première et seconde positions de ladite chemise tubulaire sont respectivement constituées par une position basse et une position haute, caractérisé en ce que la chemise présente sa partie inférieure une restriction de son diamètre interne, coopérant avec une pièce fixée au câble ou une surépaisseur de celui-ci au-dessous du raccord, de façon à réaliser le passage de ladite chemise de sa première position à sa seconde position sous l'action d'une traction dirigée de bas en haut exercée sur le câble, cette traction réalisant un auto-serrage du câble entre ledit épaulement interne de la chemise et ledit organe de sectionnement. Ce mode de réalisation est particulièrement avantageux.The invention relates more particularly to a cable cutter connection as defined above in which said first and second positions of said tubular jacket are respectively constituted by a low position and a high position, characterized in that the jacket has its lower part a restriction of its internal diameter, cooperating with a part fixed to the cable or an excess thickness of the cable below the connector, so as to effect the passage of said jacket from its first position to its second position under the action of a traction directed from the bottom upwards exerted on the cable, this traction carrying out a self-tightening of the cable between said internal shoulder of the jacket and said sectioning member. This embodiment is particularly advantageous.
Selon une variante du mode de réalisation particulièrement avantageuse, le raccord coupe-câble comporte une butée basse et une butée haute pour ladite chemise, un ressort de rappel repoussant ladite chemise jusqu'à sa butée basse et au moins une goupille cisaillable maintenant ladite chemise dans sa position basse.According to a particularly advantageous variant of the embodiment, the cable cutter connector comprises a low stop and a high stop for said sleeve, a return spring pushing said sleeve up to its low stop and at least one shearable pin holding said sleeve in its low position.
Ce raccord comporte avantageusement des moyens de guidage du coulissement de ladite chemise, ces moyens de guidage comportant au moins un doigt de calage angulaire engagé dans une rainure de guidage.This connection advantageously includes means for guiding the sliding of said jacket, these guide means comprising at least one angular setting finger engaged in a guide groove.

Ce câble passe par exemple de l'extérieur vers l'intérieur du train de tiges par l'intermédiaire d'un raccord à fenête latérale 1 c (Figs 3, 4 et 5) qui n'apparaît pas sur les figures 1 et 2.
La câble 2 est, par exemple, d'un type utilisé pour des diagraphies ou interventions réalisées se-Ion la technique décrite dans le brevet français 2.501.777 et ses additions précitées.
Le raccord 1 comporte un corps tubulaire 3 dans lequel peut coulisser une chemise 5.The
La chemise coulissante 5 est déplaçable entre deux positions définies par des butées respectivement haute 6 et basse 7 en étant guidée au moyen d'un doigt 8 solidaire du corps 1 et engagé dans une rainure 9. Ce doigt assure également le calage en rotation de la chemise.The sliding
La chemise 5 est normalement en butée basse (Fig. 1), repoussée dans cette position par un ressort 10 et maintenue dans cette position par un pion ou goupille cisailtable 11. Cette première posi- fion offre un libre passage axiat au câble 2.The
La chemise 5 comporte à sa partie inférieure :
- -une restriction de
diamètre 12 jouant le rôle de butée pour la partie de plusgrand diamètre 13 surmontant lecorps 14 de la barre decharge 4, - -un épaulement interne à rebord tranchant en
demi cercle 15 sur lequel viendra s'appliquer lecâble 2, - -un bras ou
doigt 16 pivotant autour d'unaxe 17 perpendiculaire à l'axe ducorps 1 dont l'extrémité 18 opposée à l'axe 17 a la forme d'un demi cercle complémentaire de la forme durebord 15.

Le fonctionnement de ce raccord est indiqué ci-dessous.The operation of this fitting is shown below.
Une traction exercée sur le câble 2 depuis la surface provoque le cisaillement de la goupille de sécurité 11.A traction exerted on the
La chemise 5 remonte alors en entraînant le bras 16 qui pivote et repousse le câble 2 jusqu'au rebord 15 qui peut être tranchant. La chemise 5 va jusqu'à la butée haute, le bras étant limité dans son déplacement positionné en face du rebord saillant (seconde position ou position haute illustrée par la figure 2).The
Sous l'effet de la traction effectuée depuis la surface, le câble 2 est auto-serré entre le bras pivotant 16 et le rebord tranchant 15 jusqu'à la création d'un point de rupture qui va entraîner la rupture du câble (Fig. 2) et la chute de la barre de charge. La portion du câble 2 comprise entre le raccord coupe-câble et la surface pourra être enroulé sur un treuil (non représenté) situé en surface.Under the effect of the traction carried out from the surface, the
Si nécessaire, la barre de charge pourra ensuite être pompée pour être déplacée jusqu'à l'extrémité supérieure du train de tiges.If necessary, the load bar can then be pumped to be moved to the upper end of the drill string.
