Description

Technical Field

[0001] The utility model relates to the field of petroleum exploration, in particular to a high-precision drilling position positioning device for petroleum exploration. Background Art

[0002] During oil exploration, operators need to determine the location of underground oil and gas resources and conduct accurate drilling. Therefore, operators need to use positioning devices to provide the exact coordinates of the drill hole location, help determine the drilling path and avoid drilling deviation from the target location, thereby improving exploration and mining efficiency. The signal receiver of the positioning device is usually installed on the surface to convert the signal into data.

[0003] Currently, after the signal receiver is installed, the rotating drill pipe and drill bit will generate vibration during operation. At this time, the vibration will be transmitted to the signal receiver, which may cause the receiver to vibrate, thereby interfering with the signal reception, thereby affecting the determination of the oil exploration drilling position; therefore, to address the above problem, a high-precision drilling position positioning device for oil exploration is proposed. Utility Model Content

[0011] Preferably, the abutment block and the rotating rod are in adaptive contact, one end of the push rod is fixedly connected to the surface of the abutment block, and the other end of the push rod is rotatably connected to the spur rack. After the spur rack is pushed by the gear, it will push the push rod. At this time, the push rod will push the abutment block to abut the surface of the rotating rod, thereby reducing the swing amplitude of the rotating rod.

[0012] The utility model is beneficial in that:

A card slot 28 is provided on the inner wall of the groove 22, and a return spring 29 is fixedly installed on the inner wall of the groove 22. The card rod 26 and the card slot 28 are adapted to be clamped, and the card rod 26 is clamped inside the card slot 28, so that the connecting rod 24 is further limited, and the end of the return spring 29 away from the inner wall of the groove 22 is fixedly installed on the surface of the rotating rod 23.

[0026] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6The anti-vibration component 4 includes a slide 401 fixedly installed on the top of the column 21, and the two end surfaces of the slide 401 are fixedly connected to a buffer spring 402, and the side of the buffer spring 402 away from the inner wall end surface of the slide 401 is fixedly connected to a push block 403, and one end of the push block 403 close to the middle of the slide 401 is fixedly connected to an arc-shaped rack 404, and the middle part of the interior of the slide 401 is slidably connected to a swing block 405, and the top of the swing block 405 is rotatably connected to a vertical rod 406, and a gear 407 is fixedly installed on the surface of the vertical rod 406, and the top of the vertical rod 406 is rotatably connected to a top plate 408, and the top of the swing block 405 is rotatably connected to a driven device 409, and the push block 403 has two and is adapted to contact with the swing block 405, and the arc-shaped rack 404 is meshed with the gear 407, and the driven device 409 consists of a fixed sleeve rotatably connected to the top of the swing block 405 and a straight tooth slidably connected to the inside of the fixed sleeve. When the spur gear 405 is moved away from the push block 403, the gear 407 rotates under the action of the spur gear 407, so the gear 407 drives the spur gear 407 to move. The end of the spur gear 405 near the center of the column 21 is fixedly installed with a telescopic rod 410, and the other end of the telescopic rod 410 is fixedly connected to the abutment block 411. The top of the telescopic rod 410 near the side of the spur gear 405 is fixedly installed with a hollow plate 412. The inside of the hollow plate 412 is slidably connected with a push rod 413, and the abutment block 411 is adapted to contact with the rotating rod 23. One end of the push rod 413 is fixedly connected to the surface of the abutment block 411, and the other end of the push rod 413 is rotatably connected to the spur gear 407. After the spur gear 405 is pushed by the gear 407, it will push the push rod 413. At this time, the push rod 413 will push the abutment block 411 to abut against the surface of the rotating rod 23, thereby reducing the swing amplitude of the rotating rod 23.

[0027] Working principle: After the operator inserts the rotating rod 23 fixedly connected to the bottom end of the receiver 3 into the inside of the groove 22, the receiver 3 and the electromagnet 27 are energized. The receiver 3 receives the positioning signal. At the same time, the electromagnet 27 will attract the magnetic block 25 after being energized. At this time, the magnetic block 25 will drive the connecting rod 24 and the rotating rod 23 to rotate, so that the connecting rod 24 rotates in the direction close to the electromagnet 27. During this process, the connecting rod 24 will drive the clamping rod 26 to rotate until the clamping rod 26 moves to be clamped in the inside of the clamping groove 28. At this time, the magnetic block 25 is in contact with the surface of the electromagnet 27. Therefore, the position of the connecting rod 24 is limited, that is, the position of the rotating rod 23 and the receiver 3 is limited.

[0028] If vibration occurs during the operation of the housing 1, the column 21 will also vibrate. During this process, the swing block 405 will move inside the slide 401. At this time, the swing block 405 will push one push block 403 on one side to move. At the same time, the swing block 405 will move away from the other push block 403 on the other side. When the swing block 405 moves away from one push block 403, the vertical rod 406 on the surface of the swing block 405 will move away from the arc-shaped rack 404 on the surface of the push block 403. At this time, the arc-shaped rack 404 on the surface of the vertical rod 406 is 4 is meshed, so the arc-shaped rack 404 pushes the meshed gear 407 to rotate, and the gear 407 rotates and pushes the meshed driven device 409. At this time, the driven device 409 is pushed and pushes the push rod 413, so that the push rod 413 moves inside the hollow plate 412 toward the abutment block 411. At this time, the push rod 413 pushes the abutment block 411, so that the abutment block 411 is pushed toward the direction of the rotating rod 23, and then the abutment block 411 abuts against the surface of the rotating rod 23 to limit it, thereby further limiting the position of the receiver 3.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
