Abstract
Description
Die Erfindung betrifft ein Tanksystem für die Aufbereitung der Spülung aus Bohrungen als Teil einer Bohranlage.The invention relates to a tank system for the preparation of the flush Drilling as part of a drilling rig.
Es sind Tanksysteme herkömmlicher Landbohranlagen bekannt, die aus zwei oder mehreren rechteckigen Tanks bestehen, in welchen die Spülung über Tage aufbereitet und gelagert wird. Für die Lagerung der Reservespülung werden entweder rechteckige Tanks oder Silos verwendet. Nachteil derartiger Tanksysteme ist die Tatsache, daß sich die Feststoffe, die in der Spülung enthalten sind, in den Ecken der rechteckigen Tanks absetzen und diese deshalb jeweils vor Auswechseln der Spülung und vor Umbauten der Bohranlagen gereinigt werden müssen. Neben dem hohen Zeitaufwand, der dafür nötig ist, führt das Absetzen der Feststoffe dazu, daß die Spülung zu einemn erheblichen Prozentsatz nicht mehr homogen ist und daß sich das nutzbare Tankvolumen verringert. Das Einsatzgebiet von rechteckigen Tanks liegt insbesondere dort, wo für Bohranlagen eine Transportierbarkeit notwendig ist. Desweiteren ist der Anschluß von rechteckigen Tanks untereinander aber kompliziert und zeitaufwendig.Tank systems of conventional land drilling rigs are known which consist of there are two or more rectangular tanks in which the flushing processed and stored for days. For the storage of the Reserve flushing uses either rectangular tanks or silos. The disadvantage of such tank systems is the fact that the solids, contained in the rinse, in the corners of the rectangular tanks discontinue and therefore before changing the rinse and before Conversions of the drilling rigs need to be cleaned. In addition to the high The time required for this, the sedimentation of the solids leads to the fact that the rinsing is no longer homogeneous to a considerable extent and that the usable tank volume is reduced. The area of application of Rectangular tanks are particularly located where one for drilling rigs Transportability is necessary. Furthermore, the connection of rectangular tanks with each other but complicated and time consuming.
In der FR 2 617 899 ist ein Verfahren sowie eine Anlage zur Behandlung von
Schlämmen bzw. Rückständen von Bohrungen beschrieben, wie sie
üblicherweise als Gruben in der Nähe von Bohrplätzen angelegt werden.
Das dort offenbarte Verfahren sieht vor, Schlämme in Sammelbehälter zu
leiten, um die feste Phase der Schlämme bzw. Rückstände von der flüssigen
Phase zu trennen. Dazu werden die Schlämme in den Sammelbehältern
über einen langen Zeitraum ruhen gelassen und ggf. ein Fällungsmittel
zugemischt (S. 10, Zeilen 33 - 37). Die Sammelbehälter sind rund und
weisen ein konisch geformtes Unterteil aus, in dem die Vorrichtung
angeordnet ist, um die festen Bestandteile zu sammeln und diese mittels
einer Hebevorrichtung nach oben aus dem Sammelbehälter zu fördern (S.
11, Zeilen 21 - 24). Die Art der Wiedergewinnung der pastenförmigen
Rückstände bestimmt die Form der Sammelbehälter (S. 11, Zeilen 15 - 20).
In dem US-Dokument 4,457,627 sind Rundtanks offenbart, die der Homogenisierung von Bohrspülung dienen. Im mittleren Teil der Rundtanks sind Quirleinrichtungen vorgesehen, die eine Turbulenz in den Rundtanks erzeugen sollen, um Ablagerungen auf dem ebenen Boden der Tanks zu verhindern.In US document 4,457,627, round tanks are disclosed which are the Serve homogenization of drilling fluid. In the middle part of the round tanks stirring devices are provided which create turbulence in the round tanks should generate to build up deposits on the flat bottom of the tanks prevent.
Die Rundtanks selbst bestehen aus zylindrischen Körpern mit einem ebenen Boden, wobei an zwei sich gegenüberliegenden Seiten die Wände im unteren Bereich der Zylinder abgeschrägt und an den Seiten, an denen die Wände nicht abgeschrägt sind, zwei Leitbleche angeordnet sind, um in Zusammenwirkung mit den abgeschrägten Wänden und dem Quirl eine kontrollierte Zirkulation zu erreichen.The round tanks themselves consist of cylindrical bodies with a flat one Floor, with the walls in two opposite sides bevelled lower part of the cylinder and on the sides where the Walls are not beveled, two baffles are arranged to in Interaction with the bevelled walls and the whisk one to achieve controlled circulation.
Daher liegt der Erfindung die Aufgabe zugrunde, ein Spülungstanksystem zu entwickeln, bei dem einerseits die vorgenannten Nachteile, wie Absetzen der Feststoffe, hoher Reinigungsaufwand und verminderte Homogenität sowie Verminderung des nutzbaren Tankvolumens der Spülung-, verhindert wird und das andererseits jedoch einfach und leicht zu transportieren ist.The invention is therefore based on the object To develop flushing tank system, on the one hand, the aforementioned Disadvantages, such as settling of the solids, high cleaning effort and reduced homogeneity and a reduction in the usable tank volume the flushing, is prevented and on the other hand simple and easy is to be transported.
Die Aufgabe wird dadurch gelöst, daß auf Containerschlitten runde Tanks angeordnet sind, deren oberen Teil zylindrisch und deren unterer Teil konisch ausgebildet ist. Durch die Anordnung der Tanks auf Containerschlitten wird vorteilhafterweise erreicht, daß man sie ebenso leicht transportieren kann wie rechteckige Tanks nach dem Stand der Technik. Vorteilhaft bei der Anordnung der runden Tanks ist weiterhin, daß im Bereich des konischen Teils Platz zum Beispiel für Hochdruckleitungen, Verteiler, Pumpen (Zentrifugalpumpen, Ladepumpen, etc.), und Ventile vorhanden ist. Darüber hinaus ist ein weiterer Vorteil, daß die Tanks aus leichterem Stahl von gleicher Materialgüte hergestellt werden können. Die Tanks sind in vorteilhafter Weise selbstreinigend, das heißt, daß weder Schaufeln noch Schläuche sowie kein Personal für Reinigungsarbeiten benötigt wird. Durch derartig ausgebildete Tanks werden die Kosten der Spülung reduziert, da nahezu das gesamte Fassungsvermögen der Spülungstanks genutzt werden kann. Mit der vorteilhaften konstruktiven Gestaltung werden außerdem kurze Aufbau- und Abbauzeiten erreicht.The object is achieved in that round tanks on container slides are arranged, the upper part is cylindrical and the lower part is conical. By arranging the tanks on Container sled is advantageously achieved that it is just as easy can transport like rectangular tanks according to the prior art. Another advantage of the arrangement of the round tanks is that in the area of the conical part space for high pressure lines, distributors, Pumps (centrifugal pumps, charge pumps, etc.), and valves are available. In addition, another advantage is that the tanks are made of lighter steel can be produced from the same material quality. The tanks are in advantageously self-cleaning, which means that neither shovels nor Hoses and no personnel is required for cleaning work. By tanks designed in this way reduce the cost of flushing since almost the entire capacity of the flushing tanks can be used can. With the advantageous constructive design also short Set-up and dismantling times reached.
Die auf dem Containerschlitten angeordneten Tanks sind als Schüttelsiebtank oder als Misch- bzw. Spülungsanmischtank ausgebildet. Vorteil dieser Anordnung ist, das, je nach Bedarf, spezielle Anforderungen erfüllende Tanks mit geringem Aufwand und effizient eingesetzt werden können.The tanks arranged on the container sled are as Shaking sieve tank or designed as a mixing or rinsing mixing tank. The advantage of this arrangement is that, depending on requirements, special requirements fulfilling tanks can be used with little effort and efficiently can.
In den Tanks sind Rührwerke angeordnet. Damit wird vorteilhaft eine Homogenisierung der Spülungsflüssigkeit erreicht. Desweiteren wird ein Absetzen von Feststoffen verhindert.Agitators are arranged in the tanks. This is advantageous Homogenization of the rinsing liquid has been achieved. Furthermore, a Prevents solids from settling.
In den Tanks sind Leitbleche angeordnet, die vorteilhaft zur besseren Durchmischung der Spülungsflüssigkeit beitragen.Baffles are arranged in the tanks, which are advantageous for better Mix the rinsing liquid.
Die Tanks sind vollständig geschlossen ausgebildet. Vorteilhafterweise wird hiermit z.B. bei einer Ölspülung eine besondere Abdeckung nicht mehr erforderlich.The tanks are completely closed. Advantageously hereby e.g. a special cover is no longer required for an oil flush required.
Mehrere Container werden zu einer Systemeinheit kombiniert, insbesondere gestapelt, angeordnet und deren Leitungen sind direkt miteinander koppelbar ausgebildet. Vorteilhaft wird somit erreicht, das Containerschlitten mit unterschiedlichen Tanks wie Schüttelsiebtanks und Mischtanks platzsparend nebeneinander bzw. übereinander angeordnet werden können, ohne aufwendige Schlauchverbindungen zwischen den Containern installieren zu müssen. An das Spülungstanksystem können dadurch auch weitere spezielle Container angeordnet werden. In derartigen Containern können sich Einrichtungen wie zum Bespiel Feststoffentfernungsequipment, Degasser-Ausrüstung, Motoren der Rührwerke, Strom- und Kontrollaggregate sowie Meßeinrichtungen zur Spülungskontrolle befinden.Several containers are combined to form a system unit, in particular stacked, arranged and their lines are directly with each other designed to be coupled. The container carriage is thus advantageously achieved with different tanks such as shaking sieve tanks and mixing tanks can be arranged side by side or on top of each other to save space, without complex hose connections between the containers need to install. This can also be used on the flushing tank system additional special containers can be arranged. In such containers facilities such as solids removal equipment, Degasser equipment, agitator motors, electricity and Control units and measuring devices for flushing control are located.
Ein Ausführungsbeispiel ist in den Figuren 1 und 2 dargestellt.

Gesamtvolumen des Spülungstanksystems beträgt 108 m3. In jedem der
Tanks 5, 6 ist ein in der Mitte angeordnetes Spülungsrührwerk 1 installiert. In
den Tanks 4, 5, 6 sind Leitbleche (nicht dargestellt) zur besseren
Durchmischung der Spülungsflüssigkeit angeordnet. Die Leitbleche sind
senkrecht, zur Tankachse radial orientiert, angeordnet. Zwischen Leitblech
und Tankwandung befinden sich Durchlässe, durch die Teile der
Spülungsflüssigkeit strömen kann, sodaß Ablagerungen im Bereich des
Übergangs zwischen Leitblech und Tankwandung vermieden werden.FIG. 1 shows a total of several container modules with
Unter dem konischen Teil der Tanks 4, 5, 6 kann der freie Raum für die
Hochdruckleitungen und Verteilungen sowie für Pumpe 7
(Zentrifugalpumpen, Ladepumpen, Ventile, etc.) genutzt werden.Under the conical part of the
