[0026] In one embodiment, Figure 1 , Figure 2 As shown, the test bench also includes a shielding box 5, a power shaft 6 and a motor power source 7. The shielding box 5 is fixed on the front support seat 1. The left end of the power shaft 6 is located inside the shielding box 5 and the right end extends to the outside of the shielding box 5.

The transmission part 8 is used to transmit the torque of the power shaft 6 to the logging instrument so that the logging instrument rotates along its own axis.

[0028] The horizontal logging while drilling instrument rotary test bench in this embodiment uses a shielding box 5 to shield the motor power source 7, effectively alleviating the problem of electromagnetic interference generated by the motor power source 7 on the logging instrument, ensuring the debugging accuracy of the logging instrument, and thus ensuring the smooth progress of the drilling operation.

[0029] In one embodiment, Figure 1 , Figure 2 As shown, the motor power source 7 includes a support frame 71 disposed in the shielding box 5, the support frame 71 is fixedly connected to the shielding box 5, and the power shaft 6 is rotatably connected to the support frame 71 through a bearing to improve the support effect on the power shaft 6. A servo motor 72 is fixedly connected to the support frame 71, and the servo motor 72 is connected to the power shaft 6 through a set of synchronous pulleys 73.

[0030] In this embodiment, "a set of synchronous pulleys 73" refers to two synchronous wheels and a synchronous belt, wherein one synchronous wheel is fixedly mounted on the output shaft of the servo motor 72, and the other synchronous pulley 73 is fixedly mounted on the power shaft 6, and the two synchronous wheels are connected by a synchronous belt so that the servo motor 72 can control the power shaft 6 to rotate smoothly.

[0031] In one embodiment, Figure 1 , Figure 2As shown, the servo motor 72 and the synchronous pulley 73 are respectively located at one end of the power shaft 6 away from the middle support seat 2, that is, the servo motor 72 and the synchronous pulley 73 are close to the left end of the power shaft 6, increasing the distance between the servo motor 72 and the logging instrument, thereby reducing electromagnetic interference.

[0032] In one embodiment, Figure 1 , Figure 3 As shown, the transmission part 8 includes a receiving frame 81 fixedly connected to the middle support seat 2, and a driven part 82 is horizontally arranged on the receiving frame 81, and the driven part 82 is rotatably connected to the receiving frame 81. A transmission shaft 83 is arranged between the power shaft 6 and the driven part 82, and the left end of the transmission shaft 83 is connected to the power shaft 6 through a transmission universal joint 84, and the right end is connected to the driven part 82 through a transmission universal joint 84, so as to improve the transmission fault tolerance rate and ensure that the torque can be transmitted smoothly.

[0033] In one embodiment, Figure 1 , Figure 3 As shown, the transmission shaft 83 is connected to the two transmission universal joints 84 respectively by fastening bolts 85, that is, the transmission shaft 83 can be disassembled, and the staff can choose a longer transmission shaft 83 to ensure that the distance between the servo motor 72 and the logging instrument is far enough to improve the electromagnetic interference problem.

[0034] In one embodiment, Figure 1 , Figure 3 As shown, the driven part 82 includes a driven shaft 821 horizontally rotatably connected to the receiving frame 81, and the left end of the driven shaft 821 is connected to the corresponding transmission universal joint 84.

An inverted U-shaped limiting frame 42 is arranged above the support plate 41, and a supporting block 43 is vertically arranged in the middle of the limiting frame 42. The bottom of the supporting block 43 is rotatably connected to a limiting roller 44, and the limiting roller 44 is used to abut against the well logging instrument.

[0036] In one embodiment, Figure 1 , Figure 4As shown, two limit seats 45 are provided on the support plate 41, and the two limit seats 45 are respectively located below the corresponding limit frames 42, and the two limit seats 45 are symmetrically distributed on both sides of the corresponding limit frames 42, and the tops of the two limit seats 45 are respectively connected to the corresponding limit frames 42. Support rollers 46 are rotatably connected to the two limit seats 45, and the support rollers 46 are used to abut against the well logging instrument.

[0037] In one embodiment, Figure 1 , Figure 4 As shown, the rotation axes of the limit roller 44 and the support roller 46 are respectively parallel to the logging instrument. When the logging instrument is placed horizontally on the two limit seats 45, the four support rollers 46 are respectively located below the logging instrument, and the two limit rollers 44 are respectively located above the logging instrument, and the limit rollers 44 and the support rollers 46 are respectively in contact with the logging instrument to achieve radial limitation of the logging instrument, thereby ensuring that the logging instrument can rotate smoothly.

[0038] In one embodiment, Figure 1 , Figure 4 As shown, the bottom of the limit seat 45 is horizontally slidably connected to the corresponding support plate 41, and the sliding direction of the limit seat 45 is perpendicular to the axial direction of the logging instrument. A control member 9 is provided on the support plate 41, and the control member 9 is used to control the corresponding two limit seats 45 to slide in a direction close to or away from each other to adjust the position of the support roller 46.

[0040] By controlling the positions of the limiting seat 45 and the support block 43, the positions of the limiting roller 44 and the support roller 46 are adjusted, so that the two limiting parts 4 can limit the well logging instruments with different outer diameters, thereby improving the adaptability of use.

[0041] In one embodiment, Figure 1 , Figure 4 As shown, the control component 9 includes a bidirectional lead screw 91 and a control nut 92. The bidirectional lead screw 91 is horizontally rotatably connected to the corresponding support plate 41, and the two ends of the bidirectional lead screw 91 are respectively threadedly connected to the corresponding limit seats 45. The control nut 92 is fixedly sleeved in the middle position of the bidirectional lead screw 91, and the control nut 92 can cooperate with an external wrench.

[0042] In one embodiment, Figure 1 , Figure 4 As shown, the limit seat 45 is connected to the corresponding support plate 41 through a fastening screw 11, and a long sliding hole 12 is provided on the limit seat 45. The length direction of the sliding hole 12 is parallel to the sliding direction of the limit seat 45, and the screw rod of the fastening screw 11 passes through the sliding hole 12.

[0043] When the position of the limit seat 45 needs to be adjusted, the two fastening screws 11 are loosened, and then the control nut 92 is driven by an external wrench to rotate the bidirectional lead screw 91, and the bidirectional lead screw 91 controls the two limit seats 45 to move synchronously, thereby realizing automatic centering adjustment of the two supporting rollers 46. Subsequently, the fastening screws 11 are tightened to fix the limit seat 45, so as to ensure the locking stability of the limit seat 45.

[0044] In one embodiment, Figure 1 , Figure 4 As shown, the control component 10 includes a control screw 101 and an adjusting hand wheel 102.

The control screw 101 is threadedly connected to the limit frame 42, and the bottom of the control screw 101 is rotatably connected to the support block 43. By adjusting the hand wheel 102 to control the rotation of the control screw, the control screw 101 can control the support block 43 to drive the limit roller 44 to move vertically, thereby realizing the position adjustment of the limit roller 44.
