Description

Technical Field

[0001] This invention relates to the field of oil drilling and production, and in particular to a drilling and production structure support frame. Background Technology

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons, occurring naturally. Petroleum reserves exist in parts of the upper crust, primarily composed of a mixture of various alkanes, cycloalkanes, and aromatics. It is a major target for geological exploration. Petroleum extraction relies on drilling operations, thus requiring specialized drilling equipment. Petroleum drilling equipment refers to equipment specifically designed for onshore and offshore oil and gas extraction. It mainly includes onshore oil drilling equipment, offshore and desert oil drilling equipment, and drilling tools (downhole drilling equipment). Of all the petroleum drilling equipment, drilling rigs account for 70%. Therefore, support devices are needed to ensure the stability of drilling rigs and other drilling equipment during operation. Since drilling rigs and other drilling equipment vary in size and structure, ordinary support devices are unlikely to provide adequate support and fixation for most drilling equipment.

[0003] Chinese Patent Publication No. CN108425635A discloses a positioning and fixing device used in oil drilling and production equipment. The device includes a base, with a groove at its upper end. Slider blocks are symmetrically arranged inside the groove. A first fixing plate and a second fixing plate are connected to the end of each slider away from the groove. A groove is provided on the side of the second fixing plate away from the first fixing plate. The first and second fixing plates have the same structure. A support frame is symmetrically connected to the upper end of the base. A screw hole is provided on one side of the support frame. A screw rod and a first connecting rod are respectively arranged inside the screw hole. The right end of the screw rod is connected to the first connecting rod. The left end is in contact with the first connecting rod, which is away from the screw and has a compression frame that matches the groove. The structure is simple and easy to operate, which realizes the fixation of the oil drilling and production equipment and facilitates the change of position of the oil drilling and production equipment, ensuring the accuracy of oil drilling and production. The structure of the above technical solution can fix the drilling and production equipment, but it cannot fix the drilling and production equipment from multiple directions. Therefore, it will lead to poor support and fixation effect. Moreover, the operation method relies mostly on manual operation. The volume of one end of the drilling and production equipment is large, and it is easy to fail to fix it properly. In addition, it cannot be flexibly adjusted according to the height of the drilling and production equipment, and the adaptability is small. Summary of the Invention

[0004] To overcome the above technical problems, the purpose of this invention is to provide a drilling and extraction structure support frame that can fix the drilling and extraction device from all directions through clamping components, achieving a stable support and fixation effect. It is also suitable for fixing drilling and extraction devices of different volumes and has a wide range of applications.

[0005] This invention provides the following technical solution:

[0006] A drilling and acquisition structure support frame includes a positioning cylinder 1, a support cylinder 2, and a fixing cylinder 3, which are fixedly arranged from bottom to top. The drilling and acquisition structure to be supported passes through the cylinders of the three cylinders. The positioning cylinder 1 is used for positioning the bottom of the drilling and acquisition structure. The support cylinder 2 is used for supporting the drilling and acquisition structure in the middle. The fixing cylinder 3 is used for clamping and fixing the drilling and acquisition structure in the upper part.

[0007] The fixed cylinder 3 has a hollow wall, forming a receiving cavity. The receiving cavity is provided with a clamping component 7 for clamping the drilling and acquisition structure and an annular support ring block 8 for supporting the clamping component 7.

[0008] The clamping assembly 7 includes multiple sets of components consisting of control push blocks 701, clamping push blocks 702, and mounting springs 703. These multiple sets of components are evenly distributed around the inner ring sidewall of the fixed cylinder 3. The control push block 701 is located at the top of the supporting ring block 8. The clamping push block 702 is fixed to the inward-facing side of the control push block 701. The inner wall of the fixed cylinder 3 has openings 9, the number of which corresponds to the number of clamping push blocks 702. The clamping push blocks 702 pass inward through the corresponding openings 9 and clamp the drilling and extraction structure. The mounting springs 703 are fixed at both ends to the control push block 701 and the inward-facing sidewall of the fixed cylinder 3, respectively, and are located below the clamping push blocks 702.

[0009] The bottom wall of the fixed cylinder 3 is provided with a length control component 10 for controlling the clamping assembly 7. The length control component 10 includes a control cylinder 1001 and a control ring frame 1002. The control cylinder 1001 is fixedly installed at the bottom of the fixed cylinder 3, and its upper movable end extends into the receiving cavity. The control ring frame 1002 is located at the upper end of the control cylinder 1001 and outside the control push block 701. The tail end of the control push block 701 contacts the control ring frame 1002. The control cylinder 1001 controls the up and down movement of the control ring frame 1002, driving the control push block 701 to push the clamping push block 702 inward through the through-hole 9 to clamp or release the drilling and acquisition structure outward.

[0010] In the above embodiment, the clamping modules in the clamping assembly that clamp the drilling and extraction mechanism facing into the cylinder are pushed inward to clamp or released outward under the up-and-down movement control of the hydraulic cylinder in the length control assembly. This allows for stable clamping and support of various drilling and extraction mechanisms whose external dimensions are smaller than the internal dimensions of the positioning cylinder, support cylinder, and fixed cylinder.

[0011] According to some implementation methods, the tail end of the control push block 701 contacts the control ring frame 1002 to form a contact plane, and the intersection of the contact surface and the longitudinal section is the contact line, which has a certain inclination angle inward or outward.

[0012] In the above embodiment, the control push block and the control ring frame slide relative to each other on the contact plane. The up and down movement of the control ring frame squeezes the control push block in the accommodating cavity, causing the clamping push block to extend or retract inward or outward.

[0013] According to some implementations, the contact line is an arc.

[0014] In the above embodiment, the arc has a connecting and transmission function, and the pushing arc surface of the control push block is in close contact with the contact arc surface at the bottom of the control ring frame, so that when the control ring frame moves downward, it can push the control push block to move inward.

[0015] According to some embodiments, the top of the positioning cylinder 1 is fixedly provided with an installation ring plate 4, and a plurality of adjusting cylinders 5 are evenly provided on the edge of the installation ring plate 4. The movable end of the adjusting cylinder 5 passes through the installation ring plate 4 from below, and the bottom of the support cylinder 2 is fixedly provided with a connecting ring plate 6, which is fixedly connected to the movable end of the adjusting cylinder 5.

[0016] In the above embodiment, the movable end of the adjusting cylinder 5 can be extended or shortened, thereby controlling the support cylinder 2 to support the drilling and acquisition structure at different positions, which can adapt to drilling and acquisition structures of different heights.

[0017] According to some embodiments, a positioning component 15 is provided below the positioning cylinder 1. The positioning component includes a positioning clamp 15 passing through the cylinder wall of the positioning cylinder 1 and an adjustment device for controlling the width of the positioning clamp.

[0018] According to some embodiments, the bottom of the positioning cylinder 1 is fixedly provided with a fixing plate 13; the adjustment device includes a hollow fixing box 14 provided on the fixing plate 13, the fixing box 14 having a track strip hole facing inward; a bidirectional lead screw 1502 is provided in the fixing box 14, one end of the bidirectional lead screw 1502 extends out of one end of the fixing box 14 and is provided with a servo motor 1501.

[0019] The positioning clamp includes two sets of identical clamping components. Each clamping component includes a mounting plate, a threaded cylinder fixed to one end of the mounting plate, and a positioning rod fixed to the other end of the mounting plate. The positioning rods of the two sets of clamping components are arranged opposite to each other. The threaded cylinder of the clamping component moves along the double-acting screw 1502 through the threads at both ends of the double-acting screw 1502 within the track bar hole. The positioning cylinder 1 has two opposite through holes on its wall, and the two through holes are symmetrical about the cross-sectional center of the positioning cylinder 1. The two positioning rods pass through the two through holes respectively, and drive the double-acting screw 1502 to rotate through the servo motor 1501. The two positioning rods clamp the drilling and acquisition structure inside the positioning cylinder 1.

[0020] In the above embodiment, the positioning clamp clamps and positions the drilling and extraction structure within the lower positioning cylinder, preventing the structure from moving downwards and becoming unstable. The function of the bidirectional lead screw is to control the simultaneous movement of the first and second positioning rods on both sides, thereby fixing the drilling and extraction equipment on both sides through the first and second positioning rods.

[0021] According to some embodiments, the inner wall of the fixed box 14 is provided with a track groove 16 corresponding to the thread of the bidirectional lead screw 1502, and the threaded cylinder is engaged in the track groove 16.

[0022] In the above embodiment, the mounting plate in the positioning clamp fixes the positioning rod and the adjustment mechanism together. Inside the threaded cylinder, the screw can move along the screw through the thread on the screw rod. The outside of the threaded cylinder is locked in the track groove. The inside and outside are locked together, which makes the overall positioning stability of the fixed box better.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The drilling and extraction structure support frame provided by this invention can fix the drilling and extraction device from various directions through the clamping components. The position of the support cylinder can be freely adjusted in the vertical direction. The positioning cylinder is equipped with a positioning clamp to accurately position the drilling and extraction mechanism at the bottom. The overall support frame provides a stable support and fixation effect and is suitable for fixing drilling and extraction devices of different diameters and heights, with a wide range of applications.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] This embodiment provides a drilling and extraction structure support frame, which includes a clamping function. For example... Figures 1-5 As shown, the system includes a cylindrical positioning cylinder 1, a support cylinder 2, and a fixing cylinder 3, arranged sequentially from bottom to top. The oil drilling rig to be supported is inserted between these three components. The bottom of the fixing cylinder 3 is welded to the top of the support cylinder 2. A mounting ring plate 4 is welded to the top of the positioning cylinder 1. Three adjusting cylinders 5 are evenly installed on the bottom edge of the mounting ring plate 4. A connecting ring plate 6 is welded to the bottom of the support cylinder 2, and the connecting ring plate 6 is installed at one end of the adjusting cylinders 5. Figure 3The inner wall of the fixed cylinder 3 is hollow, forming a receiving cavity. Inside the cavity, a clamping assembly 7 is located above the inner sidewall of the receiving cavity, and an annular support ring block 8 is located below the inner sidewall of the receiving cavity to support the clamping assembly 7. The clamping assembly 7 includes multiple sets of components consisting of control push blocks 701, clamping push blocks 702, and mounting springs 703, evenly distributed around the inner annular sidewall of the fixed cylinder 3. The control push blocks 701 are located on top of the support ring block 8. The mounting springs 703 are welded at both ends and fixed between the control push blocks 701 and the inner sidewall of the fixed cylinder 3. The clamping push blocks 702 are welded to the inner side of the control push blocks 701. The inner wall of the fixed cylinder 3 is provided with a through-hole 9. The number and position of the through-hole 9 correspond to the clamping push block 702. The clamping push block 702 is inserted into the corresponding through-hole 9. The bottom wall of the fixed cylinder 3 is provided with a length control component 10 for controlling the clamping component 7. The length control component 10 includes a control cylinder 1001 and a control ring frame 1002. The control cylinder 1001 is fixedly installed on the outer side of the bottom surface of the fixed cylinder 3. Its upper movable end passes through the bottom of the fixed cylinder 3 and extends into the receiving cavity. The control ring frame 1002 is set in the receiving cavity, located at the upper end of the control cylinder 1001 and outside the control push block 701.

[0039] Specifically, such as Figure 3 and Figure 5 As shown, there are eight clamping components 7 and eight through ports 9. In some larger drilling and extraction structure support frames, the number of clamping components 7 and eight through ports 9 can be appropriately increased and arranged symmetrically around the center to stabilize the drilling and extraction device. The bottom of the control ring frame 1002 is provided with a contact arc surface 11, and one side of the control push block 701 is provided with a pushing arc surface 12, which is in close contact with the contact arc surface 11.

[0040] In this embodiment, the clamping assembly 7 can fix the drilling and extraction device from various directions. During use, the positioning cylinder 1 is placed outside the mine, and then the drilling and extraction device is placed from above inside the fixing cylinder 3. The extraction structure of the drilling and extraction device extends into the mine through the support cylinder 2 and the positioning cylinder 1. The drilling and extraction device can rest on top of the support cylinder 2, thus providing support. The clamping assembly 7 then fixes the drilling and extraction device. During fixing, the control cylinder 1001 is connected to an external power supply. By controlling the retraction of the control cylinder 1001, the control cylinder 1001 can drive the control ring frame 1002 to move downwards. Figure 3As shown, when the control ring frame 1002 moves downward, the control push block 701 contacts the control ring frame 1002 by pushing the arc surface 12. Therefore, when the control ring frame 1002 moves downward, it can push the control push block 701 to move inward. The control push block 701 can adaptively compress the mounting spring 703 and push the clamping push block 702 to move along the opening 9. The clamping push block 702 can press against the drilling and production device from all directions, thereby fixing the drilling and production device. After clamping and fixing, the control cylinder 1001 can be closed.

[0041] Example 2:

[0042] This embodiment provides a drilling and extraction structure support frame, which, in addition to the clamping function as shown in Embodiment 1, also includes a height adjustment function, specifically, as follows: Figure 2 As shown, it includes a positioning cylinder 1, a support cylinder 2, and a fixing cylinder 3. The positioning cylinder 1, support cylinder 2, and fixing cylinder 3 are arranged sequentially from bottom to top. The fixing cylinder 3 is welded to the top of the support cylinder 2. The top of the positioning cylinder 1 is welded with an installation ring plate 4. Three adjusting oil cylinders 5 are evenly arranged in a ring around the bottom edge of the installation ring plate 4. The bottom of the support cylinder 2 is welded with a connecting ring plate 6. The connecting ring plate 6 is fixedly installed on the movable end above the adjusting oil cylinders 5.

[0043] In this embodiment, the height between the support cylinder 2 and the positioning cylinder 1 can be adjusted by adjusting the hydraulic cylinder 5. Therefore, it can be adjusted according to the exposed height of the mine. When adjusting the height, the hydraulic cylinder 5 is connected to an external power source. The hydraulic cylinder 5 can drive the support cylinder 2 and the fixed cylinder 3 to move up and down. When the bottom of the connecting ring plate 6 contacts the top of the mine wellhead, the hydraulic cylinder 5 can be closed.

[0044] Example 3:

[0045] This embodiment provides a drilling and mining structure support frame suitable for positioning functions in mines. It includes a positioning cylinder 1, a support cylinder 2, and a fixing cylinder 3, arranged sequentially from bottom to top. The fixing cylinder 3 is welded to the top of the support cylinder 2. A mounting ring plate 4 is welded to the top of the positioning cylinder 1. Three adjusting cylinders 5 are evenly installed on the bottom edge of the mounting ring plate 4. A connecting ring plate 6 is welded to the bottom of the support cylinder 2 and installed at one end of each adjusting cylinder 5. A clamping assembly 7 is provided inside the fixing cylinder 3. The clamping assembly 7 includes a control push block 701, a clamping push block 702, and a mounting spring 703. A receiving cavity is provided inside the fixing cylinder 3, and a support ring block 8 is welded into the receiving cavity. The control push block 701 is located on top of the support ring block 8, and the mounting spring 703 is welded to the control push block 701. 1. A clamping push block 702 is welded to one side of the control push block 701 on the inner wall of the accommodating cavity. A through-hole 9 is provided between the accommodating cavity and the inner wall of the fixed cylinder 3. One end of the clamping push block 702 is locked in the through-hole 9. A length control assembly 10 is provided in the fixed cylinder 3. The length control assembly 10 includes a control cylinder 1001 and a control ring frame 1002. The control cylinder 1001 is fixedly installed at the bottom of the fixed cylinder 3. The control ring frame 1002 is set in the accommodating cavity. The control ring frame 1002 is installed at one end of the control cylinder 1001 and is located on one side of the control push block 701. There are eight clamping assemblies 7 and eight through-holes 9. A contact arc surface 11 is provided at the bottom of the control ring frame 1002. A pushing arc surface 12 is provided on one side of the control push block 701. The pushing arc surface 12 is in close contact with the contact arc surface 11.

[0046] Specifically, such as Figure 6 , Figure 7 and Figure 8As shown, a fixing plate 13 is welded to the bottom of the positioning cylinder 1, and a fixing box 14 is welded to the fixing plate 13. A positioning assembly 15 is provided on the fixing box 14. The positioning assembly 15 includes a servo motor 1501, a bidirectional lead screw 1502, a first threaded cylinder 1503, a second threaded cylinder 1504, a first mounting plate 1505, a second mounting plate 1506, a first positioning rod 1507, and a second positioning rod 1508. A track strip hole is opened in the fixing box 14, forming an adjustment cavity. One end of the bidirectional lead screw 1502 is mounted on the inner wall of the adjustment cavity through a rotating shaft. The servo motor 1501 is fixedly mounted on one side of the fixing box 14, and the other end of the bidirectional lead screw 1502 is mounted on the output shaft of the servo motor 1501. The center position of the bidirectional lead screw 1502 and the center of the positioning cylinder 1 are set on the same vertical plane. The first threaded cylinder 1502... 503 and the second threaded cylinder 1504 are engaged and installed on both sides of the bidirectional screw 1502. The first mounting plate 1505 is welded to one side of the first threaded cylinder 1503, and the second mounting plate 1506 is welded to one side of the second threaded cylinder 1504. A track groove 16 is provided between the adjusting cavity and the outer wall of the fixed box 14. The first mounting plate 1505 and the second mounting plate 1506 are both locked in the track groove 16. The first mounting plate 1505 and the second mounting plate 1506 are respectively set on both sides of the positioning cylinder 1. The first positioning rod 1507 is welded to one side of the first mounting plate 1505, and the second positioning rod 1508 is welded to one side of the second mounting plate 1506. The positioning cylinder 1 has a first through hole 17 and a second through hole 18 respectively on both sides. The first positioning rod 1507 is locked in the first through hole 17, and the second positioning rod 1508 is locked in the second through hole 18.

[0047] The first threaded cylinder 1503 and the second threaded cylinder 1504 are the same size and specifications. The first mounting plate 1505 and the second mounting plate 1506 are the same size and specifications. The first positioning rod 1507 and the second positioning rod 1508 are the same size and specifications. The width of the first mounting plate 1505 and the second mounting plate 1506 is the same as the width of the track groove 16. The diameter of the first positioning rod 1507 and the second positioning rod 1508 is the same as the diameter of the first through hole 17 and the second through hole 18.

[0048] In this embodiment, the positioning component 15 can easily fix the positioning cylinder 1 to the outside of the mine and ensure that the positioning cylinder 1 is aligned with the center of the mine, thereby ensuring good stability during use and facilitating the alignment of the drilling and mining device with the mine. During positioning, the positioning cylinder 1 is placed outside the mine, and then the drilling and mining device is placed inside the fixing cylinder 3 from above. The acquisition structure of the drilling and mining device extends into the mine through the support cylinder 2 and the positioning cylinder 1. The servo motor 1501 is connected to an external power supply, and the servo motor 1501 can drive the bidirectional lead screw 1502 to rotate. Figure 7As shown, the servo motor 1501 can drive the bidirectional lead screw 1502 to rotate. Since the first threaded cylinder 1503 and the second threaded cylinder 1504 are meshed and installed on both sides of the bidirectional lead screw 1502, and the first mounting plate 1505 and the second mounting plate 1506 are both locked in the track groove 16, when the bidirectional lead screw 1502 rotates, the first threaded cylinder 1503 and the second threaded cylinder 1504 can move towards the center position of the bidirectional lead screw 1502 at the same time. Then, the first mounting plate 1505 and the second mounting plate 1506 can move along the track groove 16, and the first positioning rod 1507 and the second positioning rod 1508 can move inward, so that the mine shaft can be clamped and fixed by the first positioning rod 1507 and the second positioning rod 1508. After fixing, the servo motor 1501 is turned off. At this time, the positioning cylinder 1 is fixedly set on the outside of the mine shaft, thus ensuring stability during use.

[0049] In use, the positioning cylinder 1 is placed outside the mine shaft, and then the drilling and extraction device is placed inside the fixed cylinder 3 from above. The drilling and extraction device can rest on top of the support cylinder 2, thus providing support. The acquisition structure of the drilling and extraction device extends into the mine shaft through the support cylinder 2 and the positioning cylinder 1. The servo motor 1501 is connected to an external power supply, and the servo motor 1501 can drive the bidirectional lead screw 1502 to rotate. Figure 7 As shown, the servo motor 1501 can drive the bidirectional lead screw 1502 to rotate. Since the first threaded cylinder 1503 and the second threaded cylinder 1504 are meshed and installed on both sides of the bidirectional lead screw 1502, and the first mounting plate 1505 and the second mounting plate 1506 are both locked in the track groove 16, when the bidirectional lead screw 1502 rotates, the first threaded cylinder 1503 and the second threaded cylinder 1504 can move simultaneously towards the center position of the bidirectional lead screw 1502. Then, the first mounting plate 1505 and the second mounting plate 1506 can move along the track groove 16, and the first positioning rod 1507 and the second positioning rod 1508 can move inward, thereby enabling the first positioning rod to move inward. Positioning rod 1507 and second positioning rod 1508 clamp and fix the mine shaft. After fixing, servo motor 1501 is turned off. At this time, positioning cylinder 1 is fixedly set on the outside of the mine shaft, thus ensuring stability during use. Then, adjusting cylinder 5 is connected to an external power supply. Adjusting cylinder 5 can drive support cylinder 2 and fixed cylinder 3 to move up and down. When the bottom of connecting ring plate 6 contacts the top of the mine shaft opening, adjusting cylinder 5 is turned off. Then, the drilling and mining device can be fixed by clamping assembly 7. During fixing, control cylinder 1001 is connected to an external power supply. By controlling the retraction of control cylinder 1001, control cylinder 1001 can drive control ring frame 1002 to move downward. Figure 3As shown, when the control ring frame 1002 moves downward, the control push block 701 contacts the control ring frame 1002 by pushing the arc surface 12. Therefore, when the control ring frame 1002 moves downward, it can push the control push block 701 to move inward. The control push block 701 can adaptively compress the mounting spring 703 and push the clamping push block 702 to move along the opening 9. The clamping push block 702 can press against the drilling and production device from all directions, thereby fixing the drilling and production device. After clamping and fixing, the control cylinder 1001 can be closed.

[0050] Example 4

[0051] In this embodiment, a drilling and extraction device with a drilling and extraction end diameter of 10m is required. During use, the drilling and extraction device is placed securely inside the fixing cylinder 3 from above the support frame. The drilling and extraction device can be placed above the support cylinder 2, thus providing support. The acquisition structure of the drilling and extraction device extends into the mine through the support cylinder 2 and the positioning cylinder 1. The servo motor 1501 is connected to an external power supply, and the servo motor 1501 can drive the bidirectional lead screw 1502 to rotate. Figure 7 As shown, the servo motor 1501 can drive the bidirectional lead screw 1502 to rotate. Since the first threaded cylinder 1503 and the second threaded cylinder 1504 are meshed and installed on both sides of the bidirectional lead screw 1502, and the first mounting plate 1505 and the second mounting plate 1506 are both locked in the track groove 16, when the bidirectional lead screw 1502 rotates, the first threaded cylinder 1503 and the second threaded cylinder 1504 can move towards the center position of the bidirectional lead screw 1502 at the same time. Then, the first mounting plate 1505 and the second mounting plate 1506 can move along the track groove 16, and the first positioning rod 1507 and the second positioning rod 1508 can move inward, so that the mine shaft can be clamped and fixed by the first positioning rod 1507 and the second positioning rod 1508. After fixing, the servo motor 1501 is turned off. At this time, the positioning cylinder 1 is fixedly set on the outside of the mine shaft, thus ensuring stability during use.
