Description

Technical Field

[0001] The utility model relates to a wire laying auxiliary platform, in particular to a wire laying auxiliary platform for comprehensive mud logging, belonging to the technical field of comprehensive mud logging. Background Technique

[0002] Comprehensive mud logging technology is to continuously record parameters such as oil, gas shows, drilling engineering, mud properties, and formation geology released from the drilled formation during oil drilling, so as to identify oil, gas, and water layers and conduct formation evaluation, source rock and oil source evaluation, monitor drilling construction, detect formation pressure, optimize drilling, and protect oil and gas layers, providing advanced methods and technologies for scientific drilling. It is widely used not only in parameter wells, pre-exploration wells, and exploration wells during new area exploration, but also plays a very obvious role in the construction of development wells and adjustment wells during old area development.

[0003] Comprehensive mud logging technology can effectively conduct formation evaluation while drilling by using a large amount of data collected by a comprehensive mud logging instrument. During specific construction, it is necessary to transmit the information data obtained by the formation evaluation instrument while drilling to the ground. The wireless communication signal underground is very poor, so different types of communication cables are required for data transmission. When using the cable, it needs to be erected. A common erection method is to directly install the detection device on the cable, and then manually send the wire to make the instrument descend in the well. Since the depth that the instrument needs to reach is generally relatively deep, manually sending the wire will cause the cable to shake during movement, and the shaking of the cable will cause the risk of the instrument hitting the wall during descent, which will further cause damage to the instrument and affect the acquisition of downhole data by the comprehensive mud logging instrument. Content of the Utility Model

[0004] The utility model provides a wire laying auxiliary platform for comprehensive mud logging, which can stably erect the cable and at the same time realize the stable movement of the cable underground.

[0005] The utility model is realized through the following technical solutions: a wire laying auxiliary platform for comprehensive mud logging, including an outer cylinder, wherein a wire laying device is arranged inside the outer cylinder. The wire laying device includes a toothed ring arranged inside the outer cylinder, the toothed ring is rotationally connected with the outer cylinder, a plurality of telescopic rods are installed on the inner wall of the outer cylinder, the other ends of the telescopic rods are installed with clamping blocks, grooves are formed on the inner side surfaces of the clamping blocks, clamping wheels are rotationally connected to the inner walls of the grooves, a first connecting block is fixed on the upper surface of the toothed ring, a second connecting block is fixed on the bottom surface of the clamping block, a rotating plate is hinged to the side surface of the first connecting block, and the other end of the rotating plate is hinged to the second connecting block.

[0006] A fixing plate is fixed to the inner wall of the outer cylinder. A motor is installed on the bottom surface of the fixing plate. A gear is installed at the output end of the motor. The gear meshes with a toothed ring. The output end of the motor can drive the gear to rotate. The rotation of the gear can drive the toothed ring to rotate.

[0007] A driving device is installed on the side surface of the clamping block. The output end of the driving device is connected to a clamping wheel. The driving device can drive the clamping wheel to rotate. While the clamping wheel squeezes the cable, the rotation of the clamping wheel completes the diversion of the cable.

The winding device includes a housing fixed to the top plate. A turntable is rotatably connected inside the housing. A sleeve is fixed to the left side surface of the turntable. A scroll spring is installed on the inner wall of the sleeve. A fixed rod is fixed to the inner wall of the housing. The other end of the scroll spring is connected to the fixed rod.

[0009] A cable is provided on the outer surface of the sleeve. One end of the cable passes through the housing and is connected to an external detection device. An installation seat is fixed to the right side surface of the turntable. Two conductive slip rings are installed on the side surface of the installation seat.

[0010] The other end of the cable is connected to the conductive slip ring. A cable is installed on the right side surface of the housing. One end of the cable passes through the housing and is connected to the conductive slip ring. The other end of the cable is connected to a comprehensive mud logging instrument.

[0011] A support rod is installed on the outer surface of the outer cylinder. The length of the support rod is greater than the size of the wellhead to be detected.

[0012] The present utility model provides a wire laying auxiliary platform for comprehensive mud logging, and its beneficial effects are as follows:

[0013] 1. For the wire laying auxiliary platform for comprehensive mud logging, by arranging the support rod to place the outer cylinder directly above the wellhead, during the process of the cable driving the detection device to move, the motor drives the gear to rotate and then drives the toothed ring to move. The movement of the toothed ring drives the rotating plate to rotate and then drives the clamping block to move. The cable is clamped and limited from the side by the clamping wheel, avoiding the shaking of the cable during the lowering process, completing the stable laying of the cable, and at the same time realizing the stable movement of the cable underground.

[0014] 2. The wire-laying auxiliary platform for comprehensive mud logging is provided with a winding device. One end of the cable of the winding device is connected to the comprehensive mud logger, and the other end is connected to the detection device. As the detection device moves, the cable moves to drive the sleeve to rotate. When the clamping wheel disengages from the cable, the elastic force of the scroll spring can drive the detection device to rise. At the same time, since the cable is connected to the conductive slip ring, the rotation of the sleeve will not drive the cable connected to the comprehensive mud logger to move, maintaining the stability of the comprehensive mud logger.

A motor 209 is installed on the bottom surface of the fixing plate 208. A gear 210 is installed at the output end of the motor 209. The gear 210 meshes with the toothed ring 201. The output end of the motor 209 can drive the gear 210 to rotate. The rotation of the gear 210 can drive the toothed ring 201 to rotate. The rotation of the toothed ring 201 causes the rotating plate 207 to rotate and then pushes the telescopic rod 202 to expand and contract. A driving device 211 is installed on the side surface of the clamping block 203. The output end of the driving device 211 is connected to the clamping wheel 204. The driving device 211 can drive the clamping wheel 204 to rotate. While the clamping wheel 204 presses the cable 406, the clamping wheel 204 rotates to complete the diversion of the cable 406.

[0026] Please refer specifically to Figure 3 , Figure 4 and Figure 5 , a top plate 3 is arranged at the top end of the outer cylinder 1. A winding device 4 is installed on the bottom surface of the top plate 3. The winding device 4 includes a housing 401 fixed to the top plate 3. A turntable 402 is rotatably connected inside the housing 401. A sleeve 403 is fixed to the left side surface of the turntable 402. A volute spring 404 is installed on the inner wall of the sleeve 403. A fixing rod 405 is fixed on the inner wall of the housing 401. The other end of the volute spring 404 is connected to the fixing rod 405. A cable 406 is arranged on the outer surface of the sleeve 403. One end of the cable 406 passes through the housing 401 and is connected to an external detection device. An installation seat 407 is fixed to the right side surface of the turntable 402. Two conductive slip rings 408 are installed on the side surface of the installation seat 407.

[0027] Please refer specifically to Figure 2 , Figure 3 , Figure 4 and Figure 5, the other end of the cable 406 is connected to the conductive slip ring 408. The cable 406 is installed on the right side surface of the housing 401. One end of the cable 406 passes through the housing 401 and is connected to the conductive slip ring 408, and the other end of the cable 406 is connected to the comprehensive mud logging instrument. The support rod 5 is installed on the outer surface of the outer cylinder 1. The length of the support rod 5 is greater than the size of the wellhead to be detected. The outer cylinder 1 is arranged directly above the wellhead through the support of the support rod 5, which facilitates the cable 406 to drive the detection device to move.

[0028] Working principle: When in use, first, the outer cylinder 1 is erected directly above the wellhead by setting the support rod 5. During the process of the cable 406 driving the detection device to move, the motor 209 drives the gear 210 to rotate, thereby driving the toothed ring 201 to move. The movement of the toothed ring 201 drives the rotating plate 207 to rotate. The rotation of the rotating plate 207 drives the clamping block 203 to move. The movement of the clamping block 203 drives the clamping wheel 204 to move. The cable 406 is clamped and limited from the side by the clamping wheel 204, avoiding the shaking of the cable 406 during the lowering process, completing the stable erection of the cable 406, and at the same time realizing the stable movement of the cable 406 in the well.

[0029] When in use, one end of the cable 406 of the winding device 4 is connected to the comprehensive mud logging instrument, and the other end is connected to the detection device. When the detection instrument needs to descend, the driving device 211 drives the clamping wheel 204 to rotate, thereby driving the cable 406 to move, completing the descent of the detection instrument. When the detection instrument needs to ascend, after the clamping wheel 204 is separated from the cable 406, the elastic force of the volute spring 404 can drive the detection device to ascend. At the same time, relying on the connection between the cable 406 and the conductive slip ring 408, the rotation of the sleeve 403 will not drive the cable 406 connected to the comprehensive mud logging instrument to move, maintaining the stability of the comprehensive mud logging instrument.
