Description

Technical Field

[0001] This invention relates to an auxiliary drilling and production device for oil, belonging to the technical field of oil drilling equipment. Background Technology

[0002] Oil casing is a steel pipe used to support the wellbore of oil and gas wells. When in use, oil casing is lowered into the wellbore of oil, gas, or water wells to support the wellbore, prevent wellbore collapse, isolate different formations, and provide a passage for subsequent drilling and oil production operations.

[0003] Conventionally, during the installation of oil casing, each casing is hoisted to the wellhead one by one by a drilling crane. Then, a person uses a hand tool to align the casing and guide it into the wellhead. Finally, a person clamps and fixes the lower casing. The upper casing and the lower casing are then spirally combined using a crane. Finally, the casing is gradually sunk into the well.

[0004] The above-mentioned oil casing installation process has the following disadvantages:

[0005] 1. Automated installation equipment (horizontal loading) has high requirements for site space and poor platform adaptability. This equipment uses horizontal loading, and due to the large length of the casing, its ground support occupies a significant area. Furthermore, during hoisting, sufficient maneuvering space is required to rotate the casing from a horizontal to a vertical position. Therefore, this equipment is limited by the confined space of the drilling platform, has poor operational adaptability, and is difficult to promote and use on drilling platforms with limited space.

[0006] 2. When manually hoisting the casing, on the one hand, when the oil casing is installed in the well, it needs to be manually dragged to align it with the wellhead. However, the accuracy of manual alignment is not high, and the labor intensity of workers dragging the casing is high. In addition, the oil casing is prone to shaking when the crane is hoisting it, and the manual operation is also relatively dangerous.

[0007] On the other hand, the crane lifts the sleeves one by one, and the next sleeve needs to be lifted manually after the current sleeve is installed. The interval between the re-lifting of the sleeves is long and the sleeves need to be re-aligned each time they are installed. The operation of sleeve installation is not continuous and the installation efficiency is low. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an oilfield auxiliary drilling and production device. On the one hand, it replaces manual labor in aligning the casing with the wellhead, improves the alignment accuracy of the casing with the wellhead during installation, and reduces the intensity of manual labor. On the other hand, it ensures the continuity of casing installation and improves the installation efficiency of the casing.

[0049] The casing clamping module on the turntable module clamps the casing from the casing bin and transports it to the clamping tower. The clamping tower can precisely clamp and position the casing, thereby aligning the casing with the wellhead. This operation replaces the traditional manual dragging alignment method, improving the alignment accuracy between the casing and the wellhead and reducing the labor intensity of workers. At the same time, because the device replaces manual high-risk operations near the swaying hoisted casing, it effectively improves the safety of the installation process.

[0050] The pipe storage compartment is used to pre-store multiple casings and supplies them in an orderly manner through the pipe conveying module. The turntable module is equipped with several pipe clamping modules, enabling continuous gripping and transfer of casings, preparing them for the next stage of installation. This setup allows for continuous casing supply and installation preparation, avoiding repeated hoisting and alignment, thereby shortening work intervals, ensuring operational continuity, and improving installation efficiency.

[0097] like Figures 1-24 As shown, this embodiment is achieved through the following technical solution: the turntable module 1 is provided with several sets of clamping modules 2 for clamping the sleeve 5, and the turntable module 1 can drive the clamping modules 2 to rotate.

[0098] A pipe compartment 4 is provided on one side of the turntable module 1. Several pipe conveying modules 6 are provided inside the pipe compartment 4. The sleeve 5 can be inserted into the pipe conveying module 6. The pipe compartment 4 can drive the pipe conveying module 6 to rotate inside the pipe compartment 4.

[0099] One side of the turntable module 1 is also equipped with a clamping tower 3, which can connect to and clamp the sleeve 5 from the pipe clamping module 2.

[0100] The clamping module 2 can be inserted into the pipe compartment 4 and clamp the sleeve 5 placed on the pipe conveying module 6.

[0101] The tube clamping module 2 includes: a support arm 201, a clamping housing 202 on the side of the support arm 201, a guide tile 208 at the opening of the clamping housing 202, and a tube clamping assembly inside the clamping housing 202, which is mirror-image arranged.

[0102] The clamping assembly includes: a clamping block 203; a plurality of first connecting rods 204 are hinged to the side of the clamping block 203; the clamping block 203 is hinged to the inner wall of the clamping housing 202 through the first connecting rods 204; a linkage slide bar 206 is slidably connected to the inner wall of the clamping housing 202; a spring rod 205 is hinged between the clamping block 203 and the linkage slide bar 206; the linkage slide bar 206 can drive the clamping block 203 to move through the spring rod 205.

[0103] Specifically, the clamping housing 202 is provided with a first sliding groove 2021 and a guide groove 2022, and the sliding block 207 is slidably connected to the first sliding groove 2021; the linkage slide bar 206 is slidably connected to the guide groove 2022.

[0104] The inner side of the clamping block 203 is provided with several anti-slip grooves 2031.

[0105] In this embodiment, the clamping block 203 has an arc-shaped groove on the side facing away from the first connecting rod 204, and an anti-slip groove 2031 is provided on the arc-shaped groove. The anti-slip groove 2031 is used to increase the friction between the clamping block 203 and the sleeve 5. The clamping block 203, the first connecting rod 204, and the clamping housing 202 form a parallelogram mechanism. The clamping blocks 203 are arranged in pairs, and the sleeve 5 can be clamped between the arc-shaped grooves of the two clamping blocks 203. In this embodiment, two pairs of clamping blocks 203 are provided, such as... Figure 8 As shown; the two clamping blocks 203 in the horizontal position can move closer to or further away from each other at the same time.

[0106] A sliding block 207 is slidably connected to the clamping housing 202, and a linkage slide bar 206 is connected to the side of the sliding block 207. A first telescopic cylinder 209 is provided on the outer wall of the clamping housing 202. The first telescopic cylinder 209 can drive the sliding block 207 to move on the clamping housing 202.

[0107] In this embodiment, the first telescopic cylinder 209 is disposed on the outer surface of the clamping housing 202, and the output end of the first telescopic cylinder 209 is connected to the sliding block 207. The sliding block 207 can slide up and down within the first sliding groove 2021, such as... Figure 8 As shown;

[0108] When the sliding block 207 moves upward, it can drive the linkage slide bar 206 to slide upward. The linkage slide bar 206 can drive the clamping block 203 to move upward through the spring rod 205. At this time, the two clamping blocks 203, which are set in a horizontal position and mirrored, move away from each other and the distance between the clamping blocks 203 increases. At this time, the sleeve 5 can be placed between the clamping blocks 203.

[0109] When the sliding block 207 moves downward, it can drive the linkage slide bar 206 to slide downward. The linkage slide bar 206 can drive the clamping block 203 to move downward through the spring rod 205. At this time, the two clamping blocks 203, which are horizontally mirrored, move closer to each other and further fit against the outer wall of the sleeve 5. The spring rod 205 supports the arc groove of the clamping block 203 to elastically fit against the outer wall of the sleeve 5. At this time, the first telescopic cylinder 209 and the sliding block 207 stop moving. Furthermore, under the combined action of its own weight and the friction between itself and the clamping block 203, the sleeve 5 further drives the two horizontally mirrored clamping blocks 203 to simultaneously press against the sleeve 5, thereby realizing the fixed clamping installation of the sleeve 5 between the clamping blocks 203.

[0110] The pipe conveying module 6 includes a support plate 601, on which a pipe seat assembly is provided.

[0111] The tube seat assembly includes: a tube holder 602, a push rod 605 movably inserted into the tube holder 602, and a spring 604 provided on the tube holder 602 to provide elastic support for the push rod 605; a pressure plate 6021 for limiting the push rod 605 is provided on the side of the tube holder 602. A flared tube sleeve 603 is nested inside the tube holder 602; the tube sleeve 603 is connected to the push rod 605; the tube sleeve 603 can move on the tube holder 602 with the push rod 605.

[0112] In this embodiment, the opening of the sleeve 603 is flared, and the bottom is an arc surface, such as... Figure 19 As shown; the arc surface facilitates the fitting of the sleeve into the sleeve 603.

[0113] The back of the support plate 601 is provided with a retaining slider 610; the retaining slider 610 is slidably connected to the tube compartment 4; the retaining slider 610 can provide circumferential constraint for the tube conveying module 6.

[0114] The bottom end of the support plate 601 is connected to a support plate 611, and several rollers 612 are provided on the top of the support plate 611. The bottom of the sleeve 5 abuts against the rollers 612. When the sleeve 5 enters or leaves the tube conveying module 6, the rollers 612 facilitate the movement of the sleeve 5 on the support plate 611. The sleeve 5 can be placed inside the tube sleeve 603, and the push rod 605 and the spring 604 can provide elastic cushioning for the tube sleeve 603 and the sleeve 5.

[0115] A stop bar assembly is provided on the side of the support plate 601. The stop bar assembly is linked with the tube compartment 4, and a part of the stop bar assembly can be movably blocked at the opening of the tube sleeve 603.

[0116] In this embodiment, the number of tube socket assemblies is two sets, such as... Figure 19 As shown; the pipe seat assemblies are set at both ends of the support plate 601, and the part of the sleeve 5 located between the two pipe seat assemblies is exposed, so that the pipe clamping module 2 can penetrate into the pipe conveying module 6 to grab the sleeve 5, as shown. Figure 24 As shown.

[0117] Specifically, the support plate 601 is provided with a linkage groove 6011.

[0118] The stop lever assembly includes: a stop lever seat 606 disposed on one side of the support plate 601, a stop lever 607 hinged to the stop lever seat 606, a linkage rod 608 hinged to one end of the stop lever 607, a part of the linkage rod 608 connected to a cam block 609, and a part of the cam block 609 connected to a cam 406; the stop lever 607 can movably cover the opening of the sleeve 603;

[0119] In this embodiment, when the linkage rod 608 moves upward, the stop rod 607 swings downward, thereby blocking the opening of the sleeve 603 and preventing the sleeve 5 from detaching from the sleeve 603.

[0120] The cam lever 609 includes: a connecting plate 6091, a guide slider 6092 connected to the connecting plate 6091, the guide slider 6092 being slidably connected to the linkage groove 6011, a pulley 6093 being provided on one side of the guide slider 6092, the pulley 6093 being fitted into the cam groove of the cam 406; and a linkage groove 6094 being provided on the side of the connecting plate 6091.

[0121] The linkage rod 608 is provided with a guide post 6081, which is slidably connected to the linkage groove 6094, such as... Figure 23 As shown.

[0122] When the tube hopper 4 drives the tube conveying module 6 to rotate, the pulley 6093 is constrained by the cam 406 and moves along the axial direction of the cam 406. At the tube inlet 4013, the cam 406 constrains the pulley 6093 to move downward. At this time, the pulley 6093 drives the cam lever 609 to move downward as a whole. The cam lever 609 further drives the linkage rod 608 to move downward, and the stop rod 607 swings upward from the opening of the tube sleeve 603, thereby releasing the obstruction of the tube sleeve 603 so that the sleeve 5 loaded into the tube hopper 4 can enter the tube sleeve 603. Normally, when the tube conveying module 6 rotates inside the tube hopper 4, the stop rod 607 will block the opening of the tube sleeve 603 to prevent the sleeve 5 from falling off the tube conveying module 6 during the conveying process.

[0123] Similarly, at the outlet 4014, the cam 406 constrains the pulley 6093 to move downward, and the stop rod 607 swings upward again from the opening of the sleeve 603, thereby releasing the obstruction of the sleeve 603 so that the clamping module 2 can take out the sleeve 5 from the sleeve 603.

[0124] Specifically, the turntable module 1 includes: a base 101, on which a turntable bearing 103 and a turntable 106 are provided. The turntable 106 is rotatably connected to the base 101 through the turntable bearing 103. A first gear 104 is provided on the turntable 106. A drive motor 102 is provided inside the base 101. A second gear 105 is provided on the output end of the drive motor 102. The first gear 104 and the second gear 105 mesh with each other.

[0125] A transfer frame 107 is provided on the turntable 106, and the clamping module 2 is connected to the transfer frame 107 via a support arm 201; a central support rod 108 is also provided on the base 101, passing through the turntable 106 and the transfer frame 107; a central bearing 109 is provided on the central support rod 108, and the transfer frame 107 is rotatably connected to the central support rod 108 via the central bearing 109; the central support rod 108 can provide support for the transfer frame 107, such as...

[0127] The drive motor 102 drives the second gear 105 to rotate, and the second gear 105 drives the turntable 106 and the adapter frame 107 to rotate. The support arm 201 is connected to the adapter frame 107. In this embodiment, the adapter frame 107 is provided with four sets of tube clamping modules 2, such as... Figure 1 As shown;

[0128] Specifically, the base 101 is provided with a transmission chamber 1011, and the transmission chamber 1011 is provided with a rotating ring groove 1012; the turntable bearing 103 is disposed in the rotating ring groove 1012; the drive motor 102, the first gear 104 and the second gear 105 are all disposed in the transmission chamber 1011; preferably, the drive motor 102 is a servo motor.

[0129] The turntable 106 includes: a cover plate 1061, a boss 1062 is provided on the end face of the cover plate 1061, and a protrusion 1063 for holding the first gear 104 is provided on the outer side of the boss 1062; the boss 1062 is fitted into the rotating ring groove 1012.

[0130] Specifically, the clamping tower 3 includes a tower body 301, and a first bracket 302 is provided on the bottom side of the tower body 301. The first bracket 302 is provided with a positioning slot 3021 for accommodating the sleeve 5. The first bracket 302 is provided with a gripping component 303, and the positioning slot 3021 is set within the gripping range of the gripping component 303.

[0131] In this embodiment, the positioning slot 3021 is used to hold the casing 5. Preferably, the bottom of the positioning slot 3021 is an arc surface. When the clamping tower 3 is installed, the positioning slot 3021 is aligned with the oil wellhead, so as to ensure that the casing 5 can be aligned with the wellhead after entering the positioning slot 3021.

[0132] A second bracket 304 is provided on the top side of the tower body 301. A slide rail 306 and a second telescopic cylinder 307 are provided on the second bracket 304. A sliding frame 305 is slidably connected to the slide rail 306. The second telescopic cylinder 307 can drive the sliding frame 305 to reciprocate. In this embodiment, the second telescopic cylinder 307 is an electric cylinder.

[0133] In this embodiment, the sliding frame 305 is conventionally in a retracted state to avoid interference with the drilling crane, such as... Figure 2 As shown; the casing 5 inserted into the well is fastened and gripped on the gripping component 303 on the first bracket 302.

[0134] After the clamping module 2 grips the casing 5 and rotates it to the position of the clamping tower 3, the drilling crane lifts and grips the casing 5. At this time, the second telescopic cylinder 307 drives the sliding frame 305 to extend outward, and at the same time, the gripping component 303 comes into contact with the casing 5, restricting the casing 5 to the gripping range of the gripping component 303, thereby achieving the alignment and limiting of the casing 5. Further, the drilling crane drives the casing 5 to rotate and spirally combine it with the casing 5 previously inserted into the well. After the combination is completed, the sliding frame 305 retracts to make room, so that the drilling crane can drive the combined casing 5 to sink down into the well. Similarly, the sinking casing 5 is fixed and gripped by the gripping component 303 on the first bracket 302, preparing for the next casing 5 combination and installation.

[0135] Optionally, the gripping component 303 on the sliding frame 305 can also temporarily grip the fixed sleeve 5.

[0136] The sliding frame 305 is equipped with a gripping component 303 for gripping the sleeve 5.

[0139] The gripping motor 3032 can drive the drive screw 3034 to rotate, the drive screw 3034 drives the push block 3035 to move, the push block 3035 drives the clamping arm 3037 to move through the clamping link 3036, and the clamping arm 3037 drives the auxiliary clamping arm 3038 and the clamp head 3039 to move synchronously to realize the opening and closing action.

[0140] Specifically, the tube 4 includes: a support plate 402, on which a cover 401, a sliding module 403 and a support cylinder 404 are provided, and the outer wall of the support cylinder 404 is provided with a guide ring groove 405 and a cam 406.

[0141] The support cylinder 404 is equipped with a tube housing motor 407, and the top of the support cylinder 404 is equipped with a rotating support seat 408. The rotating support seat 408 is equipped with an adapter seat 410, and the adapter seat 410 is rotatably connected to the rotating support seat 408 through a tube housing bearing 409. Preferably, the tube housing motor 407 is a servo motor.

[0142] The adapter 410 is provided with a tube compartment guard plate 412, which is rotatably connected to the adapter 410 via a guard plate bearing 411.

[0143] One end of the support plate 601 is connected to the adapter 410, keeping the slider 610 slidably connected to the guide ring groove 405; the support plate 611 is connected to the sliding module 403.

[0144] The tube storage motor 407 drives the adapter 410 to rotate, thereby driving the tube conveying module 6 to rotate inside the tube storage 4.

[0145] In this embodiment, when the casing 5 is loaded into the casing 4, the casing 5 can be clamped by a drilling crane or a robotic arm and enter the casing 4 through the inlet and inlet 4013 of the pipe transfer channel 416 and then installed onto the pipe conveying module 6.

[0146] The sliding module 403 includes a slider and a guide rail, with a tray 611 connected to the slider.

[0147] The top of the cover 401 is provided with an outer guide seat 413; the tube compartment guard plate 412 is provided with an inner guide seat 414; a rotating pipe channel 416 is provided between the outer guide seat 413 and the inner guide seat 414.

[0148] Both the outer guide seat 413 and the inner guide seat 414 are provided with a plurality of guide rollers 415. In this embodiment, the guide rollers 415 are elastic rollers, and the sleeve 5 can be squeezed through the rotating tube channel 416 to elastically pass through the guide rollers 415.

[0149] The cover 401 is provided with an inlet 4013 and an outlet 4014; the inlet 4013 is provided with a first guide plate 4011 in a flared shape, and the outlet 4014 is provided with a second guide plate 4012.

[0150] The inlet and outlet of the pipe channel 416 correspond to the inlet 4013 and outlet 4014, respectively.

[0151] Specifically, the outer guide seat 413 includes: a first upper seat plate 4131 and a first base plate 4132. A guide guard plate 4133 is provided on the first base plate 4132 near the inlet 4013. A guide roller 415 is rotatably connected between the first upper seat plate 4131 and the first base plate 4132.

[0152] The inner guide seat 414 includes: a second upper seat plate 4141 and a second base plate 4142, and a guide roller 415 is rotatably connected between the second upper seat plate 4141 and the second base plate 4142.

[0153] The specific operating principle of this invention is as follows:

[0154] Loading and storage of casing 5: First, external equipment (such as a drilling rig or robotic arm) loads a single casing 5 into the casing delivery module 6 through the pipe transfer channel 416 at the top of the casing 4 and the inlet 4013. Inside the casing 4, the casing motor 407 drives the adapter 410 to rotate, thereby rotating the casing delivery module 6. This aligns the opening of the casing delivery module 6 with the inlet 4013. At this point, the casing delivery module 6 reaches the loading position. Under the action of the cam 406, the stop rod assembly on the casing delivery module 6 swings upward, opening the opening of the casing 603. Guided by the guide roller 415, the casing 5 smoothly slides into the casing 603, its bottom resting on the roller 612 of the support plate 611, completing the loading of a single casing 5. The casing 4 can continue to rotate the casing delivery module 6, sequentially rotating multiple casing delivery modules 6 to the inlet 4013 to achieve batch casing loading. After loading is completed, as the pipe conveying module 6 rotates away from the inlet 4013 inside the pipe compartment 4, the stop bar 607 is blocked by the cam 406 onto the opening of the sleeve 603 to prevent the sleeve 5 from detaching from the pipe conveying module 6 during subsequent conveying.

[0155] The gripping and transfer of sleeve 5: When sleeve 5 needs to be retrieved, the pipe storage motor 407 drives the pipe conveying module 6 to rotate to the outlet 4014 of the pipe storage 4. At this position, the stop rod assembly is constrained by the cam 406, and the stop rod 607 swings upward, removing itself from the opening of the sleeve 603, thus releasing the obstruction of sleeve 5. At the same time, the unloaded clamping module 2 on the turntable module 1 enters the pipe storage 4 from the outlet 4014 in advance, waiting for the pipe conveying module 6 to clamp sleeve 5 to reach the clamping position of the clamping module 2. The clamping module 2 can extend into the pipe storage 4. When the pipe conveying module 6 rotates to the clamping position of the clamping module 2, the exposed part of sleeve 5 in the pipe conveying module 6 can be inserted into the guide plate 208; at this time, the clamping parts of the pipe conveying module 6 and the clamping module 2 are axially aligned along the axis of the sleeve 5 to be transferred.

[0156] The clamping module 2 clamps the sleeve 5: The first telescopic cylinder 209 is activated, causing the sliding block 207 to slide within the first slide groove 2021. The sliding block 207 controls the mirror-mounted clamping blocks 203 via the linkage slide bar 206 and the spring rod 205. Specifically: when the first telescopic cylinder 209 moves the sliding block 207 upward, the clamping blocks 203 move away from each other, leaving space for the sleeve 5; when the clamping blocks 203 are located on both sides of the sleeve 5, the first telescopic cylinder 209 moves the sliding block 207 downward, causing the paired clamping blocks 203 to move closer to each other, and under the elastic action of the spring rod 205, the arc-shaped grooves fit against the outer wall of the sleeve 5, thereby achieving the clamping blocks 203 clamping onto the sleeve 5.

[0157] After the clamping module 2 reliably clamps the sleeve 5, the drive motor 102 continues to drive the turntable 106 and the adapter frame 107 to rotate along a predetermined trajectory. The clamping module 2 is fixedly connected to the adapter frame 107, which drives the entire clamping module 2, along with the sleeve 5 it clamps, to rotate along an arc trajectory. At the clamping position of the clamping module 2, the rotation trajectory of the pipe conveying module 6 is tangent to the rotation trajectory of the clamping module 2; the sleeve 5 carried by the pipe conveying module 6 can be clamped onto the clamping module 2 at the point where the trajectories are tangent. Further, the clamping module 2 drives the sleeve 5 to smoothly disengage from the sleeve 603 of the pipe conveying module 6. The sleeve 5 enters the rotation trajectory of the clamping module 2 and completely disengages from the pipe compartment 4 through the outlet 4014 of the pipe compartment 4. The rollers 612 on the pallet 611 play a role in reducing friction and assisting the sleeve 5 to disengage smoothly during this process. At this point, the clamping module 2 completely detaches the clamping sleeve 5 from the pipe compartment 4 and the pipe conveying module 6.

[0158] After detaching from the casing 4, the casing 5 is still some distance from the ground, causing it to fall. At this point, under the action of its own weight and friction, the clamping block 203 moves further inward. The clamping block 203 further clamps the casing 5 securely through the parallelogram linkage mechanism, achieving reliable self-locking gripping.

[0159] Sleeve 5 is transferred to clamping tower 3: After the clamping module 2 successfully clamps the sleeve 5, the turntable module 1 drives the clamping module 2 carrying the sleeve 5 to transport it from the pipe bin 4 to the preset clamping tower 3 station.

[0160] Clamping tower 3 assists in docking and installation: The gripping component 303 on the first bracket 302 at the bottom of clamping tower 3 has pre-grabbed and fixed the previous section of casing 5 extending into the wellhead. The positioning slot 3021 ensures the alignment of the new casing 5 with the downhole casing 5. When the clamping module 2 transports the new casing 5 to the clamping tower 3, the drilling rig first grips the new casing 5 from the clamping module 2. Correspondingly, after the drilling rig successfully grips the casing 5, the clamping module 2 releases the casing 5. The sliding frame 305 at the top of clamping tower 3 extends outward, and the gripping component 303 on it grips, aligns, and limits the new casing 5, ensuring precise alignment between the new casing 5 and the downhole casing 5.

[0161] Subsequently, the drilling rig moves the aligned new casing 5 and spirally connects it to the downhole casing 5. After the connection is completed, the sliding frame 305 retracts, making room for the drilling rig to lower the connected combined casing 5. After the combined casing 5 is lowered, the gripping component 303 on the first bracket 302 grips and secures the lowered casing 5, preparing for the connection of the next casing 5.

[0162] Finally, the empty clamping module 2 rotates back to its clamping position in the pipe bin 4 along with the turntable module 1, ready to connect with the pipe conveying module 6 to grab the next sleeve 5. The entire device repeats this cycle, realizing the operation process of sleeve 5 from storage, conveying, grabbing, transfer to auxiliary docking installation.

[0163] Of course, the above description is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the embodiments of the present invention. The present invention is also not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of the present invention should fall within the patent coverage of the present invention.
