Description

Technical Field

[0001] The present invention relates to the technical field of drilling and production equipment, and in particular to a precise positioning oil drilling and production equipment. Background Art

[0002] As the core equipment for oil and gas exploration and development, oil drilling and production equipment focuses on underground rock fragmentation, wellbore construction, and resource extraction. It is mainly composed of a drilling rig system, a circulation system, a well control system, and a monitoring system. The working principle is that the drill bit breaks the formation under the action of drilling pressure and rotational torque, and the drilling fluid circulates to carry rock cuttings and stabilize the well wall. At the same time, the wellbore trajectory is controlled in real time to ensure accurate hitting of the oil reservoir. In this process, single-rod connection operations - that is, stopping the pump after the drill string is fully drilled, pulling out the square drill rod, and connecting a new drill rod to extend the drill string - account for more than 70% of the non-drilling time of drilling operations, becoming a key bottleneck restricting efficiency.

[0003] During the single-joint drilling process, when casing is lifted from the pipe rack to the drill floor using a hook or sling, it often exhibits unstable motion due to its large slenderness ratio, offset center of gravity, and inertia, manifesting as a pendulum-like sway or uncontrolled rotation. This dynamic instability not only greatly increases the difficulty of adjusting the casing's spatial position—operators must repeatedly try to adjust the angle by pulling the rope or manually pushing and supporting it, which can take up to 30% of the time required for normal operation—but also poses a serious safety threat to on-site personnel. The uncontrolled swinging of the casing end, often weighing over a ton, can generate up to 10kJ of impact kinetic energy, enough to penetrate guardrails or cause serious injury. Summary of the Invention

DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1, as Figures 1 to 3As shown, the present invention proposes a precise positioning oil drilling device, comprising a support column 1, a turntable device 101 for driving the support column 1 to rotate, and support seats 102 slidably installed at the upper and lower ends of the support column 1. The turntable device 101 can drive the support column to rotate (the turntable device 101 is a prior art and will not be described in detail here). The support seats 102 on the upper and lower sides are fixedly connected by a reinforcing rod 103, so that the support seats 102 on both sides can move synchronously. A fifth hydraulic rod 104 is fixedly installed on the turntable device 101, and the output shaft of the fifth hydraulic rod 104 is fixedly connected to the support seat 102 below. The fifth hydraulic rod 104 can drive the two support seats 102 to move synchronously, so that the height of the support seat 102 can be adjusted. Multiple casings 5 are installed on the support column 1. The height of the casing 5 can be adjusted by moving the height of the support seat 102, which facilitates the control of the height of the casing 5. The casing 5 can be driven to move by rotating the support column 1. When connecting a single pipe, the position of the casing 5 can be quickly adjusted.

[0035] like Figures 4 and 5 As shown, this embodiment also includes a plurality of support positioning modules 2 installed on the lower support seat 102. The support positioning module 2 includes a positioning component rotatably installed on the support seat 102. The positioning component fixes one end of the sleeve 5. When connecting a single root, the sleeve 5 needs to be moved to a vertical state. Directly lifting one end of the sleeve 5 will make the sleeve 5 easy to shake, which is not conducive to improving the safety of the construction site. When one end of the sleeve 5 is limited, the other end of the sleeve 5 is lifted, and the sleeve 5 will rotate along the specified trajectory of the limited end, avoiding shaking of the sleeve 5 when moving to the vertical state, avoiding unstable movement of the sleeve 5, and ensuring the safety of the construction site.

[0036] Among them, the supporting and positioning module 2 includes a plurality of first telescopic rods 201 fixedly mounted on the support seat 102 below, a first connecting plate 202 fixedly mounted on the plurality of first telescopic rods 201, a second hydraulic rod 203 fixedly mounted on the support seat 102, an output shaft of the second hydraulic rod 203 fixedly connected to the first connecting plate 202, and a support frame 204 fixedly mounted on the first connecting plate 202, the second hydraulic rod 203 can drive the connecting plate 202 to move, thereby driving the sleeve 5 connected to the positioning assembly to move, when the sleeve 5 is in a vertical state, the sleeve 5 can be extended or retracted outward, and the sleeve 5 can rotate with the rotation of the support column 1, that is, the second hydraulic rod 203 can be used to control the rotation and diameter change of the sleeve 5, and the support column 1 drives the sleeve 5 to rotate, so that the sleeve 5 can move freely on the plane, which is convenient for docking the sleeve 5 with the sleeve 5 to be connected, thereby facilitating the installation of the sleeve 5 and improving the installation efficiency of the sleeve 5.

[0037] Furthermore, the positioning assembly includes a supporting seat 205 rotatably mounted on the support frame 204 below, a first clamping block 206 fixedly mounted on the supporting seat 205, guide rods 207 fixedly mounted at both ends of the first clamping block 206, a second clamping block 208 slidably mounted on the two guide rods 207, a first hydraulic rod 209 fixedly mounted on the first clamping block 206, an output shaft of the first hydraulic rod 209 fixedly connected to the second clamping block 208, the second clamping block 208 can be driven to move by the first hydraulic rod 209, so that the second clamping block 208 is close to or away from the first clamping block 206, and then the second clamping block 208 and the first clamping block 206 can be clamped and fixed on one end of the sleeve 5 by the first hydraulic rod 209, and when the other end of the sleeve 5 rotates, it will drive the supporting seat 205 to rotate, ensuring that the sleeve 5 can move to a vertical state.

[0038] like Figure 6 As shown, this embodiment also includes a plurality of fixing modules 3 installed on the upper support seat 102. The fixing module 3 fixes the other end of the sleeve 5. When the sleeve 5 is lifted, the top end of the sleeve 5 needs to be fixed to complete the fixation of the sleeve 5. This work can be completed by the fixing module 3.

[0039] Furthermore, the fixing module 3 includes a plurality of second telescopic rods 301 fixedly mounted on the upper support seat 102, a mounting plate 302 fixedly mounted on the plurality of second telescopic rods 301, a third hydraulic rod 303 fixedly mounted on the support seat 102, an output shaft of the third hydraulic rod 303 fixedly connected to the mounting plate 302, a fixing part for fixing the sleeve 5 fixedly mounted on the mounting plate 302, and the mounting plate 302 is driven by the third hydraulic rod 303 to move, so that the mounting plate 302 and the connecting plate 202 move synchronously, thereby completing the position adjustment of the sleeve 5.

[0040] Among them, the fixing part includes a slide 304 provided on the mounting plate 302, and two fastening blocks 305 are slidably installed in the slide 304. A fourth hydraulic rod 306 is fixedly installed on both sides of the mounting plate 302. The output shaft of the fourth hydraulic rod 306 corresponds to the fastening block 305 one by one and is fixedly connected. Before the sleeve 5 moves to the vertical position, the four hydraulic rod 306 drives the two fastening blocks 305 away from each other to facilitate the sleeve 5 to enter the interior of the two fastening blocks 305. When the sleeve 5 moves to the vertical position and enters between the two fastening blocks 305, the four hydraulic rod 306 drives the two fastening blocks 305 to approach each other, and the sleeve 5 is clamped and fixed by the two fastening blocks 305.

[0041] This embodiment also includes a lifting component 4 installed on one side of the support column 1. The lifting component 4 includes a traction rope 401. A buckle mechanism 402 is installed on the traction rope 401 to fix or loosen the sleeve 5. The lifting component 4 tightens or loosens the traction rope 401, and the buckle mechanism 402 can be pulled by the traction rope 401 to move. The buckle mechanism 402 clamps and fixes the sleeve 5, and is automatically set to relax by itself. When the sleeve 5 moves to a vertical state, the buckle mechanism 402 will automatically disengage to cancel the fixation of the sleeve 5, and when the traction rope 401 is continuously tightened, the buckle mechanism 402 can slide out from the top of the sleeve 5 (the lifting component 4 and the buckle mechanism 402 both adopt existing technologies and are not described here).

[0042] In this embodiment, the second clamping block 208 can be driven to move by the first hydraulic rod 209, so that the second clamping block 208 is close to or away from the first clamping block 206, and then the second clamping block 208 and the first clamping block 206 can be clamped and fixed on one end of the sleeve 5 by the first hydraulic rod 209, and when the other end of the sleeve 5 is rotated, the supporting seat 205 will be driven to rotate, ensuring that the sleeve 5 can be moved to a vertical state.

[0043] After the casing 5 is hoisted, the top of the casing 5 needs to be fixed. The fourth hydraulic rod 306 drives the two fastening blocks 305 to approach each other, and the casing 5 is clamped and fixed by the two fastening blocks 305.

[0044] By controlling the rotation and diameter change of the casing 5 through the second hydraulic rod 203 and driving the casing 5 to rotate through the support column 1, the casing 5 can be freely moved on the plane, making it easy to dock the casing 5 with the casing 5 to be connected, thereby facilitating the installation of the casing 5 and improving the installation efficiency of the casing 5.

[0045] Example 2, as Figures 7 and 8 As shown, based on the first embodiment, a sleeve transport component 6 is installed on one side of the support column 1. The sleeve transport component 6 moves the sleeve 5 and inserts one end of the sleeve 5 into the support positioning module 2. When the sleeve 5 is moved from a horizontal state to a vertical state, one end of the sleeve 5 needs to be connected to the support positioning module 2, and then the other end of the sleeve 5 can be hoisted. This work can be completed by the sleeve transport component 6 and can reduce labor costs and reduce the workload of workers.

[0046] Furthermore, the casing transport component 6 includes two guide frames 601, a slider 602 is slidably installed in the guide frame 601, and a lifting frame 603 is rotatably installed on the two sliders 602. A driving rod 604 is fixedly installed on the slider 602, and a cylinder 605 is slidably installed on the driving rod 604. The other end of the cylinder 605 is rotatably connected to the frame, and a sixth hydraulic rod 606 is rotatably installed on the frame. The output shaft of the sixth hydraulic rod 606 is rotatably connected to one of the cylinders 605. When the sixth hydraulic rod 606 is extended and retracted, it will drive the cylinder 605 to rotate, and the rotating cylinder 605 will drive the driving rod 604 to rotate, and the driving rod 604 will slide inside the cylinder 605, thereby causing the slider 602 to move along the track on the guide frame 601, which can drive the lifting frame 603 to rise and move horizontally, and then the casing 5 located above the lifting frame 603 can be inserted into the supporting positioning module 2.

[0047] The two groups of cylinders 605 are arranged in parallel, which makes the lifting frame 603 cylinder 605 and the ground form a parallelogram, that is, the lifting frame 603 will always remain in a horizontal state during the movement, which is convenient for conveying the casing 5.

[0048] like Figures 9 and 10 As shown, in this embodiment, a centering positioning module 7 is installed on one side of the support column 1. The centering positioning module 7 positions the two ends of the sleeve 5 and drives the middle of the sleeve 5 to be aligned with the lifting frame 603 to the same vertical plane. In order to increase the speed of connecting the sleeve, the initial position of the sleeve 5 should be kept consistent each time the connection is made. This requires positioning the sleeve 5 when installing it to ensure that the bottom of the sleeve 5 in the vertical state is in the same plane. Under the same parameters, there is no need to measure and adjust the distance separately, which can effectively increase the connection speed of the sleeve 5.

[0049] Furthermore, the centering and positioning module 7 includes two driving cylinders 701 fixedly mounted on the frame, a sealing block 714 is slidably mounted in the driving cylinder 701, a pull rod 702 is fixedly mounted on the sealing block 714, a support rod 703 is fixedly mounted on the pull rod 702, a support sleeve 704 is fixedly mounted on the support rod 703, a positioning plate 705 is slidably mounted in the support sleeve 704, a liquid storage tank 706 is fixedly mounted on the frame, a partition 707 is fixedly mounted in the liquid storage tank 706, the partition 707 divides the interior of the liquid storage tank 706 into two liquid storage tanks 708, and a sealing plate is slidably mounted in the liquid storage tank 708. 709. A push rod 710 is fixedly installed on the sealing plate 709. The two push rods 710 are fixedly connected by a synchronization plate 711. A seventh hydraulic rod 712 is fixedly installed on the frame. The output shaft of the seventh hydraulic rod 712 is fixedly connected to the synchronization plate 711. Connecting ports are provided at both ends of the liquid storage tank 708. Oil pipes 713 are fixedly installed on the connecting ports. The two oil pipes 713 on the same liquid storage tank 708 correspond to and are connected with the two ends of the driving cylinder 701 one by one. The driving cylinder 701, the liquid storage tank 708 and the oil pipe 713 are all filled with hydraulic medium, which is a liquid that cannot be compressed under the working environment.

[0050] When the position of the sleeve 5 is adjusted, the positioning plate 705 is pulled out, and the two sealing plates 709 are driven to move synchronously by the seventh hydraulic rod 712. The sealing plates 709 will squeeze the hydraulic medium inside the liquid storage tank 708 and squeeze the hydraulic medium into the two driving cylinders 701. Since the two sealing plates 709 keep moving synchronously and the cross-sections of the two liquid storage tanks 708 are equal, the hydraulic medium entering the two driving cylinders 701 is equal, and the hydraulic medium entering the driving cylinder 701 will squeeze the sealing block 714 to move, which makes the sealing block 71 4 can drive the pull rod 702 to move, and then drive the positioning plate 705 to move. Since the connection directions of the oil pipes 713 on the two driving cylinders 701 are opposite, the movement directions of the positioning plates 705 on both sides are opposite, and then the positioning plates 705 on both sides move synchronously in opposite directions, which can push the casing 5 to move, so that the middle part of the casing 5 moves to the middle part of the lifting frame 603, thereby completing the positioning of the casing 5. In order to ensure the accuracy of the positioning of the casing 5, a vacuum suction cup assembly can be set on the lifting frame 603 to adsorb and fix the casing 5.

[0051] The working principle of this embodiment is that when the sixth hydraulic rod 606 is extended and retracted, it will drive the cylinder 605 to rotate, and the rotating cylinder 605 will drive the driving rod 604 to rotate, and the driving rod 604 will slide inside the cylinder 605, thereby causing the slider 602 to move along the track on the guide frame 601, which can drive the lifting frame 603 to rise and move horizontally, and then the sleeve 5 located above the lifting frame 603 can be inserted into the support positioning module 2.

[0052] The positioning plates 705 on both sides are synchronously moved in opposite directions, which can push the sleeve 5 to move, so that the middle part of the sleeve 5 moves to the middle part of the lifting frame 603, thereby completing the alignment of the sleeve 5.

[0053] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
