Abstract
Description
Technical Field
[0001] The invention relates to an auxiliary oil drilling device, belonging to the technical field of oil drilling equipment. Background Art
[0002] Oil casing is a steel pipe used to support the well wall of oil and gas wells. When in use, the oil casing is lowered into the wellbore of oil, gas and water wells to support the well wall, prevent the well wall from collapsing, and isolate different strata to provide a channel for subsequent drilling and oil production operations.
[0003] Conventionally, during installation, oil casing is manually hoisted to the wellhead one by one using a drilling crane. Then, the casing is aligned and guided into the wellhead using handheld tools. Finally, the lower casing is manually clamped and fixed. The upper casing is screwed together with the lower casing using a crane, and finally, the casing is gradually lowered into the well. The above-mentioned installation process of oil casing has the following disadvantages: 1. Automatic installation equipment (horizontal loading) requires high space requirements and has poor platform adaptability. This equipment uses horizontal loading, and due to the length of the casing itself, the ground pipe rack requires a large area. In addition, during the lifting process, the casing needs ample maneuvering space to flip from a horizontal to a vertical position. Therefore, this equipment is limited by the limited space on the drilling platform, with poor operational adaptability, making it difficult to promote and use on drilling platforms with limited space.
[0004] 2. When manually lifting 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 manual alignment accuracy is not high and the worker's dragging the casing to align the casing is labor-intensive. In addition, the crane is prone to shaking when lifting the oil casing, and manual operation is also dangerous. On the other hand, the crane hoists the casing one by one, and manual labor is required to complete the installation of the current casing before hoisting the next casing. The interval between re-hoisting of the casing is long and the casing needs to be realigned each time it is installed. The operational continuity of the casing installation is poor and the installation efficiency is low. Summary of the Invention
[0005] The technical problem to be solved by the present invention is: to overcome the shortcomings of the existing technology and provide an oil-assisted drilling and production device. On the one hand, it replaces manual work to align the casing with the wellhead, improves the alignment accuracy of the casing and the wellhead during installation, and reduces manual labor intensity; on the other hand, it ensures the continuity of the casing installation and improves the installation efficiency of the casing.

[0053] The tube clamping assembly includes: a clamping block 203; a plurality of first connecting rods 204 are hinged on the side of the clamping block 203; the clamping block 203 is hinged to the inner wall of the clamping shell 202 through the first connecting rod 204; a linkage slide 206 is slidably connected to the inner wall of the clamping shell 202, and a spring rod 205 is hinged between the clamping block 203 and the linkage slide 206, and the linkage slide 206 can drive the clamping block 203 to move through the spring rod 205.
[0054] Specifically, a first sliding groove 2021 and a guide groove 2022 are provided on the clamping housing 202 , and the sliding block 207 is slidably connected to the first sliding groove 2021 ; the linkage sliding bar 206 is slidably connected to the guide groove 2022 .
[0055] A plurality of anti-slip grooves 2031 are provided on the inner side of the clamping block 203 .
[0056] In this embodiment, the side of the clamping block 203 facing away from the first connecting rod 204 is provided with an arc groove, and the arc groove is provided with an anti-slip groove 2031, which 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 shell 202 form a parallelogram mechanism; the clamping blocks 203 are arranged in pairs, and the sleeve 5 can be clamped between the arc grooves of the two clamping blocks 203. In this embodiment, two pairs of clamping blocks 203 are provided, such as Figure 8 The two clamping blocks 203 in the horizontal position can move closer to or farther away from the opposite side at the same time.

The spring rod 205 supports the arc groove of the clamping block 203 to elastically fit into the outer wall of the sleeve 5. At this time, the first telescopic cylinder 209 and the sliding block 207 stop moving. Further, the sleeve 5, under the combined action of its own gravity and the friction between itself and the clamping block 203, further drives the two clamping blocks 203 set in horizontal positions to fit tightly to the sleeve 5 at the same time, thereby realizing the fixed clamping installation of the sleeve 5 between the clamping blocks 203.

[0063] The bottom end of the support plate 601 is connected to a support plate 611, which is equipped with several rollers 612. The bottom of the sleeve 5 abuts against the rollers 612. When the sleeve 5 enters or leaves the pipe conveying module 6, the rollers 612 facilitate the movement of the sleeve 5 on the support plate 611. The sleeve 5 can be placed in the pipe sleeve 603.

[0076] The turntable 106 includes a cover plate 1061 , an end surface of which is provided with a boss 1062 , an outer side of the boss 1062 is provided with a bump 1063 for clamping the first gear 104 ; the boss 1062 is fitted into the rotating ring groove 1012 .
[0077] Specifically, the clamping tower 3 includes a tower body 301, and a first bracket 302 is provided at the bottom of the side of the tower body 301. The first bracket 302 is provided with a positioning groove 3021 for accommodating the sleeve 5; the first bracket 302 is provided with a grabbing component 303, and the positioning groove 3021 is set within the grabbing range of the grabbing component 303.
[0078] In this embodiment, the positioning notch 3021 is used to hold the casing 5. Preferably, the bottom of the positioning notch 3021 is an arc surface. When the clamping tower 3 is installed, the positioning notch 3021 is aligned with the oil wellhead, thereby ensuring that the casing 5 can be aligned with the wellhead after entering the positioning notch 3021.
[0079] A second bracket 304 is provided on the top side of the tower body 301. The second bracket 304 is provided with a slide rail 306 and a second telescopic cylinder 307. The slide rail 306 is slidably connected to a sliding frame 305. 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.
[0080] In this embodiment, conventionally, the sliding frame 305 is in a retracted state to avoid interference with the drilling crane, such as Figure 2 As shown, the grabbing assembly 303 on the first bracket 302 is fastened to grab the casing 5 that has been inserted into the well.
[0081] After the pipe clamping module 2 grabs the casing 5 and rotates to the working position of the clamping tower 3, the drilling crane lifts and grabs 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 grabbing assembly 303 fits close to the casing 5, and the casing 5 is restricted to the grabbing range of the grabbing assembly 303, thereby realizing the alignment and limiting of the casing 5. The drilling crane further 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 way, thereby facilitating the drilling crane to drive the combined casing 5 downward into the well; similarly, the sunken casing 5 is fixedly grabbed by the grabbing assembly 303 on the first bracket 302, preparing for the next casing 5 combination and installation.
[0082] Optionally, the grabbing assembly 303 on the sliding frame 305 can also temporarily grab the fixed sleeve 5 .

[0086] The grabbing motor 3032 can drive the driving screw 3034 to rotate, and the driving screw 3034 drives the pushing block 3035 to move. The pushing block 3035 drives the clamping arm 3037 to move through the clamping link 3036. 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.
[0087] Specifically, the tube magazine 4 includes a support plate 402 , on which a cover tube 401 , a sliding module 403 and a support tube 404 are provided. A guide ring groove 405 and a cam 406 are provided on the outer wall of the support tube 404 .

[0091] The tube warehouse motor 407 drives the adapter 410 to rotate, thereby driving the tube conveying module 6 to rotate in the tube warehouse 4.
[0092] In this embodiment, when the casing 5 is loaded into the pipe magazine 4, the casing 5 can be clamped by a drilling crane or a mechanical arm, enters the pipe magazine 4 through the inlet of the pipe transfer channel 416 and the pipe inlet 4013, and is installed on the pipe conveying module 6.
[0093] The sliding module 403 includes a slider and a guide rail, and the support plate 611 is connected to the slider.
[0094] An outer guide seat 413 is provided on the top of the cover tube 401 ; an inner guide seat 414 is provided on the tube bin guard plate 412 ; and a tube rotation channel 416 is provided between the outer guide seat 413 and the inner guide seat 414 .
[0095] A plurality of guide rollers 415 are provided on the outer guide seat 413 and the inner guide seat 414. In the present embodiment, the guide rollers 415 are elastic rollers, and the sleeve 5 can squeeze the guide rollers 415 from the rotating tube channel 416 to pass elastically.
[0096] The cover tube 401 is provided with a pipe inlet 4013 and a pipe outlet 4014 ; the pipe inlet 4013 is provided with a first guide plate 4011 in an expanded shape, and the pipe outlet 4014 is provided with a second guide plate 4012 .
[0097] The inlet and outlet of the pipe transfer channel 416 correspond to the pipe inlet 4013 and the pipe outlet 4014 respectively.
[0098] 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 pipe inlet 4013. The guide roller 415 is rotatably connected between the first upper seat plate 4131 and the first base plate 4132.
[0099] The inner guide seat 414 includes a second upper seat plate 4141 and a second base plate 4142 , and the guide roller 415 is rotatably connected between the second upper seat plate 4141 and the second base plate 4142 .
[0100] The specific operating principle of the present invention is as follows: Loading and Storage of Casing 5: First, an external device (such as a drilling crane or robotic arm) loads a single piece of casing 5 into the pipe conveying module 6 through the pipe transfer channel 416 at the top of the pipe hopper 4 and the pipe inlet 4013. The pipe hopper motor 407 within the pipe hopper 4 drives the adapter 410 to rotate, thereby rotating the pipe conveying module 6 so that its opening aligns with the pipe inlet 4013. At this point, the pipe conveying module 6 reaches the loading position. Under the action of the cam 406, the stopper 607 of the pipe conveying module 6 swings upward, opening the opening of the pipe sleeve 603. Guided by the guide rollers 415, the casing 5 slides smoothly into the pipe sleeve 603, its bottom resting on the rollers 612 of the support plate 611, completing the storage of the single piece of casing 5. The pipe hopper 4 can continue to rotate the pipe conveying module 6, sequentially transferring multiple pipe conveying modules 6 to the pipe inlet 4013, enabling batch loading of casing. After loading is completed, as the tube conveying module 6 rotates away from the tube inlet 4013 in the tube warehouse 4, the blocking rod 607 blocks the opening of the tube sleeve 603 under the action of the cam 406, preventing the sleeve 5 from detaching from the tube conveying module 6 during subsequent conveying.
[0101] Grasping and transporting the sleeve 5: When the sleeve 5 needs to be taken, the tube warehouse motor 407 drives the tube conveying module 6 to rotate to the pipe outlet 4014 of the tube warehouse 4. At this position, the blocking rod assembly is constrained by the cam 406, and the blocking rod 607 swings upward, removing it from the opening of the tube sleeve 603, thereby releasing the obstruction to the sleeve 5. At the same time, the turntable module 1 drives the unloaded pipe clamping module 2 to enter the tube warehouse 4 from the pipe outlet 4014 in advance, waiting for the tube conveying module 6 to clamp the sleeve 5 and reach the clamping position of the pipe clamping module 2. The pipe clamping module 2 can partially penetrate into the tube warehouse 4. When the tube conveying module 6 rotates to the clamping position of the pipe clamping module 2, the exposed part of the sleeve 5 in the tube conveying module 6 can be stuck in the guide shoe 208; at this time, the parts of the tube conveying module 6 and the pipe clamping module 2 that clamp the sleeve 5 are axially overlapped along the axis of the sleeve 5 to be transported.
[0102] The tube clamping module 2 clamps the sleeve 5: the first telescopic cylinder 209 actuates, driving the sliding block 207 to slide within the first slide groove 2021. The sliding block 207 controls the mirrored 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 on both sides of the sleeve 5, the first telescopic cylinder 209 moves the sliding block 207 downward, and the paired clamping blocks 203 approach each other. Under the elastic action of the spring rod 205, the arc-shaped grooves fit the outer wall of the sleeve 5, thereby clamping the clamping blocks 203 to the sleeve 5.
[0103] After the tube 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 tube clamping module 2 is fixedly connected to the adapter frame 107, and the adapter frame 107 drives the entire tube clamping module 2 together with the sleeve 5 it clamps to rotate in a circular arc trajectory. In the clamping position of the tube clamping module 2, the rotation trajectory of the tube conveying module 6 is tangent to the rotation trajectory of the tube clamping module 2; the sleeve 5 carried by the tube conveying module 6 can be clamped onto the tube clamping module 2 at the tangent point of the trajectory. Furthermore, the tube clamping module 2 drives the sleeve 5 to smoothly disengage from the pipe sleeve 603 of the tube conveying module 6, and the sleeve 5 enters the rotation trajectory of the tube clamping module 2 and completely detaches from the pipe warehouse through the pipe outlet 4014 of the pipe warehouse 4. The roller 612 on the support plate 611 plays a role in reducing friction and assisting the sleeve 5 to disengage smoothly in this process. At this point, the sleeve 5 held by the tube clamping module 2 is completely separated from the tube magazine 4 and the tube conveying module 6.
[0104] After being separated from the pipe magazine 4, the sleeve 5 is still at a distance from the ground, and the sleeve 5 falls. At this time, under the action of the sleeve 5's own gravity and friction, the clamping block 203 moves further inward, and the clamping block 203 further firmly clamps the sleeve 5 through the parallelogram linkage mechanism, realizing reliable self-locking grasping.
[0105] The sleeve 5 is transferred to the clamping tower 3: After the pipe clamping module 2 successfully clamps the sleeve 5, the turntable module 1 drives the pipe clamping module 2 carrying the sleeve 5 from the pipe warehouse 4 to the preset workstation of the clamping tower 3.
[0106] The clamping tower 3 assists in docking and installation: The grabbing assembly 303 on the first bracket 302 at the bottom of the clamping tower 3 has pre-grabbed and fixed the previous section of the casing 5 that extends into the wellhead. The positioning notch 3021 ensures that the new casing 5 is aligned with the downhole casing 5. When the clamping module 2 transports the new casing 5 to the clamping tower 3, the drilling crane first grabs the new casing 5 from the clamping module 2. Correspondingly, after the drilling crane successfully grabs the casing 5, the clamping module 2 moves to release the casing 5. The sliding frame 305 at the top of the clamping tower 3 extends outward, and the grabbing assembly 303 thereon grabs, aligns and limits the new casing 5 to ensure that the new casing 5 is accurately aligned with the downhole casing 5.
[0107] The drilling crane then drives the aligned new casing 5, threading it into the downhole casing 5. Once connected, the sliding frame 305 retracts, clearing the way for the drilling crane to lower the connected combined casing 5. After the combined casing 5 is lowered, the gripping assembly 303 on the first bracket 302 recaptures and secures the lowered casing 5, preparing for the connection of the next casing 5.
[0108] Finally, the empty pipe clamping module 2 rotates back to its clamping position in the pipe warehouse 4 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 to realize the operation process of the sleeve 5 from storage, conveying, grabbing, transporting to auxiliary docking installation.

The present invention is not limited to the above examples. Equivalent changes and improvements made by ordinary technicians in this technical field within the essential scope of the present invention should all fall within the scope of the patent of the present invention.
