[0025] In the implementation process, it is particularly worth pointing out that the displacement sensor 3 model is selected according to actual needs, and the motor 41 model is selected according to actual needs, which meets the work. The shape of the barrel 1 is cylindrical, and the middle is hollow. The staff can disassemble the two barrel covers 2 by rotating the bolts on the two barrel covers 2, and can repair the mechanical parts inside the barrel 1. After finishing, the two barrel covers 2 are fixed back to the far away position. When measuring the wellbore diameter of the oil well, the external hoisting equipment drives the horizontal well four-arm caliper to move to the inside of the wellbore, so that the four displacement sensors 3 move. When the four displacement sensors 3 are attached to the inner walls of the four directions of the wellbore, the displacement sensor 3 transmits the signal to the external controller, the controller controls the driving assembly, and the movement of the displacement sensor 3 is stopped. When the four displacement sensors 3 are all attached to the inner walls of the oil well, the displacement sensor 3 transmits the displacement signal to the controller, and the controller transmits the signal to the external computer, and starts to measure the wellbore diameter of the oil well in multiple directions.

The rubber sleeve 483 is installed on the outer wall of the sleeve 482. When the logging instrument collides with the inner wall of the oil well, the two rubber sleeves 483 are impacted. The material of the rubber sleeve 483 is relatively soft and can absorb part of the impact force.

[0028] Further, the connecting column 45 is provided with a pulley 451 away from the shell 44. When the connecting column 45 moves, the connecting column 45 drives the pulley 451 to move. The outer wall of the pulley 451 is attached to the inner wall of the empty box 47. The pulley 451 moves in the slide way of the inner wall of the empty box 47, thereby guiding the connecting column 45 to move more stably.

[0029] In the implementation process, it is worth pointing out that when the connecting column 45 moves, the connecting column 45 drives the pulley 451 to move.

[0033] In the implementation process, it is worth pointing out that the outer wall of the connector 21 is provided with mounting holes. The number of mounting holes on one connector 21 is four. The staff can install the logging instrument on the external hoisting equipment through the mounting holes on the connector 21, thereby moving the whole logging instrument.

[0034] Specifically, first, the staff installs the logging instrument to the external hoisting equipment through the mounting hole on the joint 21, and when the logging instrument moves, the motors 41 on both sides are connected to the external power supply, the motors 41 drive the gear 42 to rotate, the gear 42 moves along the rack 43, and the rack 43 moves, thereby driving the shell 44 to move, the shell 44 drives the connecting column 45 to move, the connecting column 45 drives the pulley 451 to move, the pulley 451 moves in the slide of the inner wall of the empty box 47, the connecting column 45 moves in the empty box 47, the connecting column 45 drives the annular sleeve 46 to move, and the two annular sleeves 46 are attached together to cover the four displacement sensors 3. After the completion, the motors 41 on both sides are stopped, and when the logging instrument collides with the inner wall of the oil wellbore, the rubber sleeve 483 on both sides is impacted, the rubber sleeve 483 drives the sleeve 482 to move, the sleeve 482 moves in the groove 481, and the sleeve 482 deforms the spring 484. In this process, the spring 484 repeatedly rebounds, and the friction between the sleeve 482 and the groove 481 consumes part of the kinetic energy, thereby playing a damping role. When the logging instrument moves to the working position, the motors 41 on both sides are rotated in the opposite direction, so that the annular sleeves 46 on both sides return to the initial position, and the four displacement sensors 3 are exposed. When the four displacement sensors 3 are attached to the inner walls of the four directions of the wellbore, the displacement sensor 3 transmits a signal to the external controller, the controller controls the driving assembly to stop the movement of the displacement sensor 3. When the four displacement sensors 3 are all attached to the inner wall of the oil wellbore, the displacement sensor 3 transmits a displacement signal to the controller, and the controller transmits the signal to the external computer, and starts to measure the wellbore diameter of the oil wellbore in multiple directions.

[0035] In example 2, by Figure 1 and 2 It can be known that the displacement sensor 3 is fixedly connected with the mounting plate 31 through bolts, the first connecting block 32 is fixedly connected to the side away from the displacement sensor 3 of the mounting plate 31, the inclined rod 33 is rotationally connected to the first connecting block 32 through a pin shaft, the second connecting block 34 is rotationally connected to the end away from the first connecting block 32 of the inclined rod 33 through a pin shaft, the connecting plate 35 is fixedly connected to the outer wall of the second connecting block 34, the electric telescopic rod 36 is fixedly connected to the inner wall of the connecting plate 35 through bolts, and the end away from the connecting plate 35 of the electric telescopic rod 36 is fixedly connected to the inner wall of the cylinder cover 2.
