Description

Technical Field

[0001] The invention belongs to the technical field of oil and gas drilling equipment and relates to a mobile folding cable trough with a cable storage function. Background Art

[0002] During cluster well drilling operations, after completing the operation of one well, the main parts of the oil rig, such as the derrick base, need to be moved to another wellhead. However, the power system and solid control system generally do not move with the main body of the drilling rig and are fixed at the well site. Therefore, the power and control cables between the main drilling rig and the power system need to be retracted and extended according to the movement of the drilling rig to adapt to the movement of the main body of the drilling rig. At present, most cluster well drilling rigs use folding cable troughs and large-capacity adjustable rail-type cable storage racks to retract and release cables. Although the current solution solves the problem of cable retraction and release, it still has the following shortcomings: First, the use of large-capacity adjustable rail-type cable storage racks for cable retraction and release has the problem of heavy structural parts; second, when the drilling rig is moved, the cables are stored in the folding cable trough and the large-capacity adjustable rail-type cable storage rack respectively, and there are two transportation units during transportation. The cables between the transportation units are connected and disconnected through explosion-proof connectors, and the matching explosion-proof connectors lead to high manufacturing costs; third, the current folding cable trough ground pipeline trough is usually realized by adding rollers at the bottom of the pipeline trough to adapt to the movement of the drilling rig between different wellheads, which has high requirements on the well site ground and there is a problem of large shaking of the pipeline trough during the movement. Summary of the invention

[0003] The purpose of the present invention is to provide a mobile folding cable trough with a cable storage function, which solves the problems in the prior art of high requirements on the well site surface and the need for matching explosion-proof connectors resulting in high manufacturing costs.

[0005] The present invention is also characterized in that

[0006] The lower guide rail type cable storage trough includes a guide rail body, and rectangular tracks are arranged on the upper ends of the two guide rail walls of the guide rail body along the length direction of the guide rail body. Pads are fixed at the positions corresponding to the two rectangular tracks at the lower end of the lower horizontal pipeline trough. The pads are embedded in the rectangular tracks and slide in the rectangular tracks. A fixed roller is rotatably installed at one end of the guide rail body close to the middle pipeline trough along its width direction. Moving guide rails I are arranged correspondingly on the two inner side walls of the end of the guide rail body away from the fixed roller along its length direction. Moving rollers are connected together in the two moving guide rails I. Rollers are arranged at both ends of the roller shaft of the moving roller. The rollers slide in the moving guide rail I on the corresponding side. There is a certain distance between the end of the moving guide rail I close to the fixed roller and the fixed roller. The distance is used to ensure that when the moving roller reaches the extreme position close to the fixed roller, the distance between the moving roller and the fixed roller will not clamp the cable.

[0007] The roller shaft of the mobile roller is provided with through holes along its length direction, and the guide rail body is provided with through holes at positions corresponding to both ends of the roller shaft of the mobile roller. When the mobile roller does not need to move, a pin is passed through the through hole on the roller shaft of the mobile roller and the through hole on the guide rail body corresponding thereto. A plurality of round steels are rotatably connected to the guide rail body below the mobile roller along the length direction of the mobile guide rail I, and the vertical distance between the upper surface of the round steel and the lower surface of the mobile roller is greater than the diameter of the cable to be passed through.

[0012] Connecting ear seat mounting holes are arranged on both sides of the connecting end of the lower guide rail cable storage trough and the extended section of the guide rail cable trough, and connecting ear seats are arranged at the corresponding positions of the extended section of the guide rail cable trough. The connecting ear seats are inserted into the corresponding ear seat mounting holes and fixedly connected by pin shafts.

[0014] The beneficial effects of the present invention are:

[0015] By using the mobile folding cable trough with cable storage function of the present invention, multiple layers of cables are arranged in parallel on the well site foundation surface, and the cable storage capacity is large; the cables do not need to be connected with connectors, which reduces the manufacturing cost. In addition, the use of a cable storage device with a guide rail reduces the cable bundling and fixing work, and the cable has only a few bends in the cable trough, avoiding damage to the cable caused by multiple retraction and release of the cable; the use of the guide rail for the transfer of the cable trough solves the problem that the existing pipeline trough transfer has high requirements for the well site surface, making the transfer process more stable, and the transfer guide rail can be used as a storage guide rail for the cable after transfer, without the need to rearrange the pipeline trough.

The lower end of the lower horizontal pipeline trough 23 is fixed with a cushion block 24 at the position corresponding to the two rectangular rails 54. The cushion block 24 is embedded in the rectangular rail 54 and slides in the rectangular rail 54. The end of the guide rail body 51 close to the middle pipeline trough 22 is rotatably installed with a fixed roller 32 along its width direction. The two ends of the guide rail body 51 away from the fixed roller 32 are fixed with a fixed roller 32. The inner wall is provided with movable guide rails Ⅰ52 along its length direction, and the two movable guide rails Ⅰ52 are commonly connected with the movable roller 33. Rollers are provided at both ends of the roller shaft of the movable roller 33, and the rollers slide in the movable guide rails Ⅰ52 on the corresponding side. There is a certain distance between the end of the movable guide rail Ⅰ52 close to the fixed roller 32 and the fixed roller 32. The distance is used to ensure that when the movable roller 33 reaches the extreme position close to the fixed roller 32, the distance between the movable roller 33 and the fixed roller 32 will not clamp the cable.

[0032] The roller shaft of the movable roller 33 is provided with a through hole along its length direction, and the guide rail body 51 is provided with through holes at positions corresponding to the two ends of the roller shaft of the movable roller 33. When the movable roller 33 is not required to move, a pin shaft 36 is passed through the through hole on the roller shaft of the movable roller 33 and the through hole on the corresponding guide rail body 51.

[0033] A plurality of round steel bars 37 are rotatably connected to the guide rail body 51 below the moving roller 33 along the length direction of the moving guide rail I 52 , and the vertical distance between the upper surface of the round steel bars 37 and the lower surface of the moving roller 33 is greater than the diameter of the cable 4 to be passed through.

[0034] Multiple insertion frames 34 are evenly arranged on both sides of the upper cable storage trough 3, and multiple sockets 35 are arranged at the positions of the lower horizontal pipeline trough 23 corresponding to the insertion frames 34. The upper cable storage trough 3 and the lower horizontal pipeline trough 23 are fixedly connected by inserting the insertion frames 34 into the sockets 35.

[0035] like Figure 6As shown, the upper cable storage trough 3 includes a cable trough body 31, in which a fixed roller a32-1 is rotatably installed at one end away from the middle pipeline trough 22 along its width direction, and movable guide rails 38 are correspondingly arranged on the two inner side walls of the end of the cable trough body 31 away from the fixed roller a32-1 along its length direction, and a movable roller a33-1 is commonly connected in the two movable guide rails 38, and rollers a are arranged at both ends of the roller shaft of the movable roller a33-1, and the roller a slides in the movable guide rail 38 on the corresponding side, and there is a certain distance between the end of the movable guide rail 38 close to the fixed roller a32-1 and the fixed roller a32-1, and the distance is used to ensure that when the movable roller a33-1 reaches the extreme position close to the fixed roller a32-1, the distance between the movable roller a33-1 and the fixed roller a32-1 will not clamp the cable.

[0036] The roller shaft of the moving roller a33-1 is provided with a through hole along its length direction, and the cable trough body 31 is provided with through holes at positions corresponding to the two ends of the roller shaft of the moving roller a33-1. When the moving roller a33-1 is not needed to move, the through hole on the roller shaft of the moving roller a33-1 and the through hole on the corresponding cable trough body 31 are jointly penetrated by a pin shaft a36-1, and a plurality of round steels a37-1 are rotatably connected along the length direction of the moving guide rail 38 below the moving roller a33-1 in the cable trough body 31, and the vertical distance between the upper surface of the round steel a37-1 and the lower surface of the moving roller a33-1 is greater than the diameter of the cable 4 to be passed through.

[0037] like Figure 3-4 As shown, the extended end of the lower guide-rail cable storage trough 5 corresponding to the sliding and folding direction of the lower horizontal pipeline trough 23 can also be detachably connected with the guide-rail cable trough extension section 7, and the upper ends of the two guide rail walls of the guide-rail cable trough extension section 7 are provided with rectangular tracks a54-1 along its length direction. After the lower guide-rail cable storage trough 5 and the guide-rail cable trough extension section 7 are connected, the rectangular tracks a54-1 and the rectangular tracks 54 are combined into one track.

[0038] Connecting ear seat mounting holes 53 are provided on both sides of the connecting end of the lower guide rail cable storage trough 5 and the guide rail cable trough extension section 7, and a connecting ear seat 71 is provided at the corresponding position of the guide rail cable trough extension section 7. The connecting ear seat 71 is inserted into the corresponding ear seat mounting hole 53 and fixedly connected by a pin shaft.

[0039] The extended section 7 of the guide rail type cable trough is sequentially provided with multiple sections, and the connection between each section and the connection mode between the lower guide rail type cable storage trough 5 and the first section of the extended section 7 of the guide rail type cable trough are the same.

[0040] Example 2

[0041] One end of the lower horizontal pipeline trough 23 is fixedly connected to the side of the base 1 through a connecting bracket 6, and the two ends of the middle pipeline trough 22 are respectively rotatably connected to the upper pipeline trough 21 and the lower horizontal pipeline trough 23 through a pin shaft. The upper pipeline trough 21 is connected to the upper part of the base 1 by a pin shaft ear plate, and the lower guide rail cable storage trough 5 and the guide rail cable trough extension section 7 are placed on the ground of the well site. The base 1 and the drilling rig are fixed. When the drilling rig is moved, the base 1 drives the lower horizontal pipeline trough 23, and the upper cable storage trough 3 slides along the lower guide rail cable storage trough 5 and the guide rail cable trough extension section 7 with the lower horizontal pipeline trough 23. The lower guide rail cable storage trough 5 and the guide rail cable trough extension section 7 are detachable and fixed and placed on the ground of the well site without moving.

[0042] One end of the guide rail body 51 of the lower guide rail cable storage trough 5 is arranged close to the wellhead, the movable roller 33 is installed on the side of the guide rail body 51 away from the wellhead, and the fixed roller 32 is installed on the side of the guide rail body 51 close to the wellhead, and can rotate around the core axis, and there is a certain distance between the end of the movable guide rail I 52 close to the fixed roller 32 and the fixed roller 32, and the distance is used to ensure that when the movable roller 33 reaches the extreme position close to the fixed roller 32, the distance between the movable roller 33 and the fixed roller 32 will not clamp the cable, play a limiting role, and ensure that the movable roller 33 and the fixed roller 32 will not clamp the cable 4 when the distance is minimum. A round steel 37 that penetrates the guide rail body 51 is installed below the movable roller 33, and the vertical distance between the round steel 37 and the movable roller 33 allows the cable 4 to pass through to prevent the cable 4 from colliding with the structural parts and causing damage. When the cable 4 contacts the round steel 37 during the process of retracting and releasing, the round steel 37 can rotate around the core axis.

[0043] Similarly, the upper cable storage trough 3 and the lower guide-type cable storage trough 5 have basically the same structure, and are mainly composed of a cable trough body 31, a fixed roller a32-1, and a movable roller a33-1. The movable roller a33-1 is installed on the side of the cable trough body 31 away from the wellhead. Rollers are installed on both sides of the movable roller a33-1, and it can move along the movable guide rails 38 on both sides of the cable trough body 31. Similarly, through holes are opened on both sides of the movable roller a33-1 and the cable trough body 31. When not moving, a pin a36-1 is inserted to lock the movable roller a33-1 to prevent it from moving. The fixed roller a32-1 is installed on the side of the cable trough body 31 close to the wellhead, and can rotate around the core shaft. A certain distance is reserved between the end of the movable guide rail 38 and the fixed roller a32-1 to ensure that the movable roller a33-1 and the fixed roller 32 will not clamp the cable 4 when the distance is minimum. A round steel a37-1 that penetrates the guide rail body is installed below the movable roller a33-1. The vertical distance between the round steel a37-1 and the movable roller a33-1 allows the cable 4 to pass through to prevent damage caused by collision between the cable 4 and the structural parts. When the cable 4 contacts the round steel a37-1 during the retraction and release process, the round steel a37-1 can rotate around the core axis.

[0044] Example 3

[0045] On the basis of Example 1 and Example 2, the specific process of laying cables in the mobile folding cable trough with cable storage function of the present invention is as follows: first, place the lower guide rail cable storage trough 5, the upper cable storage trough 3, and the lower horizontal pipeline trough 23 in appropriate positions on the ground of the well site in sequence, so that the moving roller 33 of the lower guide rail cable storage trough 5 is located on the side away from the wellhead, the fixed roller a32-1 of the upper cable storage trough 3 and the moving roller 33 of the lower guide rail cable storage trough 5 are correspondingly arranged at the same end, the lower horizontal pipeline trough 23 is connected to the middle pipeline trough 22 on one side close to the wellhead, and the lower guide rail cable storage trough 5 and the moving roller 33 of the upper cable storage trough 3 are fixed with a pin 36 to prevent movement. Then lay the cable 4 in the pipeline trough: as shown in FIG. Figure 7 As shown, first, one end of the cable 4 is passed through between the movable roller 33 and the round steel 37 of the lower guide rail cable storage trough 5, and laid toward the fixed roller 32. After bypassing the fixed roller 32, the cable is laid toward the movable roller 33 and comes out from under the movable roller 33. After bypassing the movable roller 33, the cable is laid from above the movable roller 33 toward the upper cable storage trough 3, and after bypassing the movable roller a32-1 of the upper cable storage trough 3, the cable is laid toward the fixed roller a33-1, and is led out from between the fixed roller a33-1 and the round steel a37-1, and continues to be laid from under the upper cable storage trough 3 into the lower horizontal pipeline trough 23. After completing the above operations, first hoist the upper cable storage trough 3 and place it above the lower horizontal pipeline trough 23, ensuring that the insertion frame 34 is inserted into the socket 35, and then hoist the upper cable storage trough 3 and the lower horizontal pipeline trough 23 onto the lower guide rail cable storage trough 5, so that the pad 24 at the bottom of the lower horizontal pipeline trough 23 is clamped in the rectangular track 54 of the lower guide rail cable storage trough 5, and finally adjust the cable 4 to ensure that the cable 4 will not be entangled in the movable folding cable trough, and lay the cables in the middle pipeline trough 22 and the lower horizontal pipeline trough 23.

[0046] The specific process of using the mobile folding cable trough with cable storage function of embodiments 1 and 2 of the present invention to perform cluster drilling operations is as follows:

[0047] After completing the drilling operation of the current well, first arrange an appropriate number of guide rail cable trough extension sections 7 according to the required transportation distance, connect the connecting ear seat 71 of the guide rail cable trough extension section 7 with the connecting ear seat mounting hole 53 of the lower guide rail cable storage trough 5, and insert the pin shaft, and connect the connecting ear seat 71 of the next section of the guide rail cable trough extension section 7 with the connecting ear seat mounting hole 53 of the previous section of the guide rail cable trough extension section 7 with the pin shaft.

[0048] like Figure 8-9As shown, when the drilling rig needs to be moved, first remove the pin 36 of the lower guide rail cable storage trough 5 for fixing the movable roller 33. As the main body of the drilling rig moves to the next well, the lower guide rail cable storage trough 5 and the extended section of the guide rail cable trough 7 are fixed on the ground, and the base 1 drags the folded pipeline trough assembly 2 and the upper cable storage trough 3 along the guide rail formed by the lower guide rail cable storage trough 5 and the extended section of the guide rail cable trough 7. During this process, the movable roller 33 of the lower guide rail cable storage trough 5 moves along the movable guide rail Ⅰ52 toward the fixed roller 32, gradually releasing the cables stored in the upper layer of the lower guide rail cable storage trough 5, and placing them inside the extended section of the guide rail cable trough 7. Since the movable roller 33 can move flexibly along the movable guide rail Ⅰ52, the movable roller 33 only serves to prevent the cable 4 from excessive bending, so the cable 4 will not be subjected to a large force during the movement. When the base 1 is moved to a length twice as long as the lower guide rail type cable storage trough 5, the movable roller 33 reaches the limit position of the movable guide rail I 52, and the cables 4 stored in the lower guide rail type cable storage trough 5 are completely released.

[0049] like Figure 10-11 As shown, when further movement is required, an extension section 7 of the guide rail cable trough is added to the ground and connected, and the pin a36-1 used to fix the movable roller a33-1 in the upper cable storage trough 3 is removed. As the base 1 moves forward, the movable roller a33-1 of the upper cable storage trough 3 rolls toward the fixed roller a32-1, gradually releasing the stored cable 4. Similarly, the movable roller a33-1 only serves to prevent the cable 4 from excessive bending. Therefore, the cable is not subjected to much force during the movement. When the base 1 moves to twice the length of the upper cable storage trough 3, the movable roller a33-1 reaches the limit of the movable guide rail 38, and the cable 4 stored in the upper cable storage trough 3 is released.

[0050] When the cable 4 needs to be recovered after drilling, firstly, the moving roller a33-1 of the upper cable storage trough 3 is wound with a rope, and the moving roller a33-1 is dragged away from the wellhead by a crane or other equipment, and the moving roller a33-1 is fixed with a pin a36-1 when the moving roller a33-1 reaches the pin hole position, thus completing the recovery of the cable 4 of the upper cable storage trough 3. Then, the upper cable storage trough 3 and the lower horizontal pipeline trough 23 are removed, and the moving roller 33 of the lower guide rail type cable storage trough 5 is wound with a rope, and the moving roller 33 is dragged toward the wellhead by a crane or other equipment, and the moving roller 33 is fixed with a pin 36 when the moving roller a33 reaches the pin hole position, thus completing the recovery of the cable 4 of the lower guide rail type cable storage trough 5.
