Handling device for drill pipes of a deep drilling device Description

The invention relates to a handling device for drill pipes of a drilling device for creating a deep hole, with at least one pipe support that is arranged vertically on a working plane of the drilling device and having an open portion through which the drill pipes are introduced into the pipe storage or removable from the pipe storage.

When drilling deep wells, for example for the extraction of oil and natural gas or for the production of energy from geothermal energy, a drilling tool is used, which is driven by a drill string consisting of drill string and drill string parts such as drill collars, drill motors or the like. As such, as drilling progresses, additional drill rods must be added to the drill string during drilling progress. These drill rods are fed from the outside. For this purpose, a pipe storage is planned in addition to the drilling rig on the drilling site.

Furthermore, during the creation of the deep hole, it is necessary to change the drilling tool either because it is worn or the geological conditions have changed, and therefore a different kind of tool becomes necessary. To change the drilling tool, the entire drill string must be removed from the well, and after a new drilling tool has been provided, reinstalled. For this purpose, the drill rods of the drill string, for example, in large systems, in each case to two or three pieces removed and installed at once, and placed in the tower of the rig upright. For this purpose, so-called finger stages are provided in the mast, on which a worker stands, and which takes over the pipe with a loop from the elevator of the Topdrives and turns off in the space between the fingers and secures or takes out the pipes. This work is difficult and has a not inconsiderable risk of injury. The object of the invention is therefore to provide a pipe store with which a drilling rig can be automated with drill pipes and the like and can be supplied safely and quickly with low maintenance in a simple manner. The object is achieved according to the invention in that the tube bearing is provided with a guide element, through which a handling space in the region of the open section which is delimited by the guide element on one side and the tube bearing on the other side results, that the handling device comprises at least one gripping element for gripping of the drill pipe, that the gripping element is horizontally movable, and the drill pipe is movable over the gripping element in the region of the handling space.

It is advantageous that an automated supply and removal of the drill pipes is made possible. Furthermore, the guide element acts as a backup, so that the drill pipes can not fall out of the pipe storage uncontrolled.

A further teaching of the invention provides that two or more pipe bearings are provided, which are connected to the guide element. This provides optimum storage space and a defined handling space.

A further teaching of the invention provides that the pipe bearing has a box-like structure, preferably with a two side walls and a rear wall, wherein the pipe bearing is preferably designed for receiving at least two drill pipes screwed together.

A further teaching of the invention provides that the tube bearing is arranged so that the open side of the pipe bearing points away from the derrick or is arranged at right angles thereto. As a result, an optimal movement of the drill pipes is made possible without disadvantageous pivoting movements.

A further teaching of the invention provides that the handling device has a retaining element, which encloses the drill pipe in the horizontal direction, and that preferably permits a vertical movement of the drill pipe. This allows a defined horizontal movement and at the same time enables a safe vertical movement.

Another teaching of the invention provides that the gripping element is vertically movable. Another teaching of the invention provides that the handling device has a lower portion and a spatially separated upper portion. Furthermore, it is advantageous that the sections are moved synchronously, wherein the synchronous method is advantageously carried out mechanically or via a control, a further teaching of the invention provides that the upper portion is arranged movable on the guide member. This allows a simple way a defined movement over the entire length of the drill pipe away.

Another teaching of the invention provides that the upper portion has a base body and a gripping or holding element which is horizontally movable relative to the base body.

A first embodiment of the device according to the invention and the method which can be used therewith are shown in FIGS. 1 to 9b.

1 shows a drilling rig 100 with a mast 102 arranged on a working platform 101, in which a so-called top drive 103 is arranged above a so-called well center 104 arranged above the borehole (not illustrated). The drilling rig 100 stands on a well site 105. Located on the well site 105 and in communication with the work platform 101 is a catwalk 106. Further, on the well site 105 adjacent to the catwalk 106 is a horizontal pipe store (not shown) for feeding individual tubes , Casings, drill collars or other components of the drill string (not shown) provided.

Parallel to the mast 102, a vertical pipe support 10 is arranged. In the tube bearing 10 are tubes 11, here in the form of so-called triples, three tubes 11 screwed together, respectively. Doubles are also possible. The tube bearing 10 consists of two boxes 12, shown in Fig. 2c, which are erected vertically. The boxes 12 have in vertically oriented form a bottom plate 13 on which projections 14 (Fig. 3a) are arranged. The Boxes have a grid frame 15 consisting of two side sections 16, 17 and a rear section 18. On the bottom of the grid frame 15 is closed by the bottom plate 13. At the top of the grid frame 15 is made open. In the region of the open top 19 finger-like projections 20 are provided, which extend from the rear portion 18 of the grid frame to the open side 21 of the grid frame. The finger-like projections 20 (FIG. 2 b, FIG. 3 b) are arranged parallel to one another, so that spaces 22 arise within which the tubes 11 can be arranged in a stack. The projections 20 have according to a particular embodiment recesses 23 in which the threaded portions 24 of the tubes 11 can be arranged. In the present embodiment (see also Fig. 3b), the threaded portions 24 are not supported in the recesses 23.

Are the tubes 1 1 stored in a box 12, so they consist with their lower threaded portion 25 on a projection 14 of the bottom plate 13. The projections 14 are arranged on the bottom plate, that the tubes 11 are arranged to the mast tilted in the box 12 in the space 22 between the finger-like projections 20. The boxes 12 are arranged on the work platform 101 so that the open side 21 of the boxes 12 point away from the mast 102. The boxes 12 are arranged on the work platform 101 so that they have a distance from each other. This creates a passageway 26 between the boxes 12, through which the tubes 11 can be moved toward or away from the well center 104. The with their open side 21 away from the mast 102 away boxes 12 are connected via a guide member 27 with each other. The guide member 27 has two parallel to the open side 21 arranged struts 28, 29. These are connected to one another at their outer ends via a transverse strut 30. The transverse strut 30 extends beyond the connecting portion between the struts 28, 29, so that a spacer 31 is formed, which is connected to the respectively away from the passage 26 side portion 16, 17. This creates a handling space 32, between the open upper side 21 of the box 12 and the guide element 27, or its strut 28. In this handling space, the tubes 11 can be moved to the tube bearing 10 during supply and / or removal. At the same time, the guide member 27 acts as a securing element, since this prevents that arranged in a box tubes 11 can fall out of this.

The boxes 12 are arranged with stops 33 on the side portions 16, 17, which - as shown in Fig. 2a - point to the open side 21. At the Construction of the rig, the boxes 12 are connected via the stops 33 with a crane and placed on the work platform 101 with its bottom plates 13. Subsequently, they are connected at their upper side 19 with the guide element 27.

Parallel to the guide element 27, an arrangement element 34 is provided on the work platform 101. This arrangement element 34 is preferably constructed analogously to the guide element 27. For removing the tubes 1 1 from the boxes 12 and the feeding of the tubes

11 to the Well Center 104 so that they can be handed over there to the Topdrive 103, a pipe manipulator 40 is provided. The pipe manipulator 40 has a lower portion 41 (Figure 2a) and an upper portion 42 (Figure 2b). In the present exemplary embodiment, the lower section has a gripping element 43 and the upper section has a holding element 44. However, it is also possible that both sections 41, 42 are designed with gripping elements 43 or the lower section 41 with a holding element 44 and the upper section 42 with a gripping element 43. The lower portion 41 has a base 45 which is movable on rails 46, which are arranged on the arrangement element 34 in the horizontal direction. The method is carried out via a drive unit, not shown, and can be done electrically or hydraulically. On the base 45 a base body 47 is arranged horizontally movable the movement of the base body 47 with respect to the base 45 is substantially perpendicular to the rails 46. The base body 47 has a bottom brace 48 on which a vertical strut 49 is arranged, the is stabilized via a diagonal strut 50 relative to the bottom strut 48. The gripping element 43 is arranged to be vertically movable on a vertical strut 51 of a gripping section 52. The vertical strut 51 is pivotally connected via two arms 53 with the vertical strut 49 of the base body 47 via rotary bushings 54. The pivoting takes place via a hydraulic cylinder 55, which is arranged between the vertical strut 49 and the vertical strut 51. The base body 47 can be displaced so far relative to the base 45, that the gripping member 43 can grip a pipe arranged in the space 22 11 that rests on the projection 14, the rear portion 18 of the box

12 is closest without the vertical strut 51 has to be pivoted relative to the vertical strut 49 of the body 47. A Further movement of the tube, for example, through the passage 26 to the Well Center 104 out, then carried out by actuation of the hydraulic cylinder 55, whereby the vertical strut 51 is pivoted parallelogram on the arms 53 and is moved accordingly to the Well Center 104.

The upper portion 42 has a base body 56 which is movable on the struts 28, 29 of the guide member 27. The main body 56 is connected to the holding element 44 so that within the main body 56 a telescopically executed feed body 57 is provided. The feed body 57 has several telescopic sections 58. The holding element 44 has two holding portions 59 which enclose the tube 11, so that it is no longer horizontally movable relative to the holding element 44. The holding portions, however, form a space 60 in the closed state, within which the tube 11 is vertically movable.

The lower portion 41 and the upper portion 42 move along the rails 46 and the guide member 27 synchronously. This is ensured either by a mechanical connection or by a correspondingly provided control.

In FIGS. 3 a to 9 b, the sequence of removal of a tube 11 from a box 12 of a tube store 10 and the feeding of the tube 11 to the well center 104 are shown. In Fig. 3a, the pipe manipulator 40 is arranged in front of the box 12 so that it can approach the pipe 11 to be removed by moving the base body 47 on the base 45 of the pipe manipulator 40 and then reach with the gripping member 43. In Fig. 3a, the starting position of the lower portion 41 of the pipe manipulator 40 is shown. In Fig. 3b, the starting position of the upper portion 42 of the pipe manipulator 40 is shown. The middle of the three arranged in Fig. 3a and 3b tubes 11 should be removed. For this purpose, the base body 47 is moved relative to the base 45 (FIGS. 4 a and 4 b) so far that the gripping element 43 can grip the tube 1 1. Synchronously, the upper portion 42 of the pipe manipulator is actuated and the holding member 44 is moved to the pipe 11 out. For this purpose, consisting of the telescopic sections 58 feed body 57 is moved relative to the main body 56 and the holding portions 59 close to the tube 11. Subsequently, the tube 1 1 by moving the gripping member 43 on the vertical brace 51 is raised, so that the lower threaded portion 25 of the tube 11 from the projection 14 of the bottom plate 13 of the box 12 triggers. Subsequently, as shown in Fig. 6a and 6b, the base body 47 relative to the base and moved synchronously to the feed body 57 relative to the Grundköper 56 or retracted, whereby the tube 1 1 is removed from the space 22 between the finger-like projections 20 and is moved into the handling space 32 between the open side 21 of the box 12 and the strut 28 of the guide member 27. Subsequently, as shown in FIGS. 7 a and 7 b, the pipe manipulator 40 or its lower section 41 and upper section 42 are displaced horizontally along the rails 46 or struts 28, 29 to the passage 26 between the boxes 12. Subsequently, the tube 11 is moved in the direction of the well center 104 through the passage 26 by first the base body 47 is moved relative to the base 45 (Figure 8) and then the vertical strut 51 on the actuation of the hydraulic cylinder 55 under the guidance of the arms 53 parallelogram is moved to the Well Center 104 out. In order to keep the lower threaded portion 25 relative to the working platform 101 in height constant, the gripping member 43 relative to the vertical strut 51 can be moved accordingly. The displacement of the retaining element 44 of the upper portion 42 is shown in Fig. 9b. In this case, in turn, the telescopic sections 58 of the feed body 57 are extended relative to the main body 56. The movement takes place synchronously with the movement of the gripping element 43.

In the area of the well center 104, the pipe can then be transferred to a further pipe manipulator, which supplies the pipe to the screwing with the drill string and the top drive 103 or its elevator (not shown). Alternatively, the pipe 1 1 can also be fed directly to the elevator of the TopDrive 103 via a corresponding arrangement of the pipe in the Well Center 104. If the tube 1 1 passed either to another pipe manipulator or the elevator of the top drive 103, the gripping member 43 and the holding member 44 can be opened and the tube are released accordingly.

If the tube 1 1 is taken over at the well center 104 and fed to the pipe store 10, the method described above is carried out in the reverse order.

A second embodiment of the device according to the invention is shown in FIGS. 10 to 15. 10 shows a drilling rig 100 with a mast 102 arranged on a working platform 101. A vertical pipe bearing 10 is arranged parallel to the mast 102. In the tube bearing 10 tubes 11, here in the form of so-called triples, in each case three tubes 11 screwed together can be arranged. Doubles are also possible. The tube bearing 10 consists of a finger stage 110 (see FIGS. 13 to 15) which has two opposite finger stage sections 111. The finger stage sections 111 have projections 20 between which spaces 22 extend, in which the tubes 11 are turned off. The projections 20 of the two finger stage sections 111 face each other with their open sides 112.

The finger stage sections 111 are connected to a guide element 27. The open sides 112 are arranged at right angles to the guide element 27. The area between the open sides 112 and the guide element 27 is the handling space 32.

If the tubes 11 are mounted in one of the finger stage sections 111, they consist with their lower thread section 25 on a projection (not shown) or in a recess which are arranged in or on the working platform 101. The projections are arranged on the bottom plate, that the tubes 11 are inclined to the mast in the finger stage sections 11 1 in the space 22 between the finger-like projections 20 are arranged. The finger stage sections 111 are arranged parallel to the work platform 101 so that the open sides 112 of the finger stage sections 11 are perpendicular to the mast 102. The finger stage sections 111 are arranged above the working platform 101 in such a way that they are at a distance from each other. This creates a passage 26 between the finger stage sections 111 through which the tubes 11 can be moved to or away from the well center.

In the handling room 32, the tubes 11 can be moved during supply and / or discharge to the tube bearing 10. At the same time, the guide member 27 acts as Securing element, since this prevents that arranged in a box tubes 1 1 can fall out of this.

Parallel to the guide element 27, an arrangement element 34 is provided on the work platform 101.

To remove the tubes 11 from the finger stage sections 11 1 and the feeding of the tubes 11 to the Well Center, so that they can be handed over there to the top drive, a pipe manipulator 40 is provided. The pipe manipulator 40 has a lower portion 41 (FIG. 12) and an upper portion 42 (FIGS. 12, 15). In the present exemplary embodiment, the lower section has a gripping element 43 and the upper section has a holding element 44. However, it is also possible that both sections 41, 42 are designed with gripping elements 43 or the lower section 41 with a holding element 44 and the upper section 42 with a gripping element 43.

The basic structure of the pipe manipulator 40 with its lower portion 41 and its upper portion 42 substantially corresponds to that previously set forth in the first embodiment. The gripping or holding element 43, 44 is horizontally movable through the passage 26 or in the handling space 32 and also under the space 22, which is the storage space of the tubes 1 1, in the direction of arrow A. At the same time, the lower portion 41 and the upper portion 42 are movable along the arrow direction B along the guide member 27 and the arranging member 34, respectively. Accordingly, depending on the position of the lower and upper portions 41, 42, the gripping or holding element 43, 44 in the passage 26 or in the handling space 32 and also under the space 22, which is the storage space of the tubes 11, positionable by a pure horizontal Move. A pivoting of the gripping or holding element 43, 44 is not provided, whereby a complex pivot drive can be omitted.

The removal of the tubes 11 from the tube bearing 10 in each space 22 from the open side 112 to the closed side 113 in the direction of arrow C and then starting from the guide element 27 closest to the room 22 in the direction of arrow D. The movement of a tube 11 from a Room 22 toward the well center, to install this in the drill string, thus takes place according to arrow E in Fig. 13. When removing the tube 1 1 from the drill string, the movement is reversed to the arrow E. It must in this embodiment, the tubes from the individual Pipe rows are taken successively, since the gripping or holding elements 43, 44 do not engage from the open side 12 in the respective space 22 but at right angles to the open side 112 and perpendicular to the projections 20, and it is therefore necessary, first the rooms To empty 22, which are the guide member 27 closest and tubes 1 1 included. When introducing the tubes 1 1 in the tube bearing 10 must be moved accordingly in reverse order.
