Description

Technical Field

[0001] The utility model relates to the technical field of drill bit fishing, in particular to a drill bit fishing device for oil drilling. Background Technique

[0002] After geological investigation and geophysical exploration, the most favorable drilling position for oil and gas accumulation is selected, and the oil and gas layer is drilled through by drilling technology to achieve the purpose of testing geophysical exploration data, understanding downhole oil and gas geological exploration data, calculating oil and gas reserves, and providing development prospects. The drilling project is abbreviated as oil and gas drilling. During the oil drilling process, the drill bit is prone to fall into the well due to operation. Therefore, a drill bit fishing device for oil drilling is required.

[0003] The applicant believes that:

[0004] When the fishing device is fishing for the drill bit, most of the time, the fishing cable sleeve is manually sorted and wound up.

Moreover, manual sorting cannot wind up and arrange the fishing cable sleeve well, and it is easy to cause the fishing cable sleeve to be messy and knotted. This not only reduces work efficiency but also easily wastes more time due to operation errors, so improvement is needed. Content of the Utility Model

[0026] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a bit fishing device for oil drilling, including a bracket 1 and a combing component 2. The combing component 2 is arranged above the bracket 1. The other end of the cable sleeve 205 is fixedly connected to a fishing head 3. A clamping component 4 is arranged inside the fishing head 3. The lower end of the bracket 1 is welded and connected to a base 5. Four corners of the lower part of the base 5 are fixedly connected with universal wheels 6. A threaded cylinder 7 is penetrated and connected inside the base 5. A screw rod 8 is in threaded connection with the inside of the threaded cylinder 7. The lower end of the screw rod 8 is connected to a support block 9 through a bearing.

[0027] Among them: when the fishing device conducts the fishing operation on the bit, first move the bracket 1 above the oil drilling wellhead through the universal wheels 6. Secondly, turn the screw rods 8 on both sides of the bracket 1 to cooperate with the threaded cylinder 7 to screw the support block 9 into the ground to support the bracket 1. Subsequently, place the fishing head 3 into the oil drilling wellhead through the cooperation of the combing component 2 and the cable sleeve 205. Then, clamp the bit through the clamping component 4. After clamping, lift the bit clamped by the fishing head 3 out of the oil drilling wellhead through the cooperation of the combing component 2 and the cable sleeve 205.

[0028] Please refer to Figure 1 and Figure 2 , a bit fishing device for oil drilling, the combing component 2 includes a sealing box 201, a driving motor 203, a winding disc 204, a cable sleeve 205, a servo motor 206, a ball screw 207, a ball nut 208, a cable drum 209, a main guiding ring 210 and a main guiding rod 211. The sealing box 201 is fixedly connected above the bracket 1. A driving motor 203 is fixedly connected to one side of the sealing box 201. The output shaft of the driving motor 203 is fixedly connected to the winding disc 204 through a coupling. The cable sleeve 205 is fixedly connected inside the winding disc 204. A servo motor 206 is fixedly connected to one side of the bracket 1. The output shaft of the servo motor 206 is fixedly connected to the ball screw 207 through a coupling. The ball nut 208 is fitted and installed on the outside of the ball screw 207. A cable drum 209 is fixedly connected to one side of the ball nut 208. The main guiding ring 210 is welded and connected below the ball nut 208. The main guiding rod 211 is penetrated and connected inside the main guiding ring 210. Both ends of the main guiding rod 211 are fixed to the bracket 1. One side of the upper part of the sealing box 201 is connected with a box door 202 through a hinge.

[0029] Among them: When the combing component 2 winds and tidies up the cable sleeve 205, the driving motor 203 rotates the winding disc 204, providing an automatic winding function for the cable sleeve 205 on the winding disc 204, enabling quick control of the length of the required cable sleeve 205. When the cable sleeve 205 is wound and unwound on the winding disc 204, the servo motor 206 drives the ball screw 207 to cooperate with the ball nut 208 to move the cable drum 209 back and forth, providing a combing and arranging function for the cable sleeve 205 inside the cable drum 209, preventing entanglement and knotting.

The rotating positive and negative thread screw rod 402 cooperates with the positive and negative thread nut 403 to drive the clamping rod 406 to perform a clamping operation inside the fishing head 3, enabling a firmer grip on the drill bit. Moreover, anti-slip teeth 407 are provided inside the clamping rod 406, preventing the clamping rod 406 from slipping easily when clamping the drill bit, ensuring that the drill bit can be safely removed from the well. At the same time, when the positive and negative thread nut 403 moves on the positive and negative thread screw rod 402, the secondary guiding ring 404 above the positive and negative thread nut 403 will move on the secondary guiding rod 405, providing a combing and limiting function for the positive and negative thread nut 403 and ensuring the stable movement of the positive and negative thread nut 403 on the positive and negative thread screw rod 402.

[0032] The working principle of the present utility model is as follows: When the fishing equipment is fishing for the drill bit, first, move the bracket 1 above the oil drilling wellhead through the universal wheels 6. Secondly, turn the screws 8 on both sides of the bracket 1 and cooperate with the threaded cylinder 7 to screw the support block 9 into the ground to support the bracket 1. Subsequently, align the fishing head 3 above the oil drilling wellhead. Then, start the driving motor 203 to drive the winding disc 204 to extend the cable sleeve 205, so that the fishing head 3 contacts the drill bit inside the oil drilling wellhead. Then, start the rotating motor 401 to drive the rotation of the positive and negative thread lead screw 402, so that the rotating positive and negative thread lead screw 402 cooperates with the positive and negative thread nut 403 to drive the clamping rod 406 to clamp the drill bit. Finally, start the driving motor 203 to drive the winding disc 204 to wind up the cable sleeve 205, so that the drill bit clamped by the clamping rod 406 is fished out of the oil drilling wellhead. In this way, the working principle and working process of a drill bit fishing device for oil drilling are completed, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
