For example, the position relationships such as front, back, up, down, left, and right are determined according to the Figure 1 layout direction of the attached drawings of the specification.

[0016] The present invention will be further described below in conjunction with embodiments and the attached drawings:

[0017] As shown in the Figure 1 attached drawings, the test tooling for the high-integration well inclination measuring instrument includes a vibration motor 1, a cylinder 2, a test nipple 3, a pressure sensor 4, a first solenoid valve 5, a second solenoid valve 6, a filter pressure reducing valve 7, a base, a power supply module, a host computer, and a control unit. The vibration motor 1 and the cylinder 2 are both fixed on the base; the second solenoid valve 6 and the pressure sensor 4 are successively and fixedly installed on the outside of the test nipple 3 from top to bottom; a first hose 8 is fixedly connected between the outlet of the filter pressure reducing valve 7 and the inlet of the first solenoid valve 5, a second hose 9 is fixedly connected between the outlet of the first solenoid valve 5 and the inlet of the second solenoid valve 6, the outlet of the test nipple 3 is hermetically and fixedly connected to the upper part of the cylinder 2, there is a piston rod in the cylinder 2 that can extend and retract downward, a connecting pipe 10 is hermetically and fixedly connected to the lower part of the cylinder 2, a piston 11 is arranged in the connecting pipe 10, a cross pipe 12 is fixedly connected to the outside of the connecting pipe 10, and a displacement detection sensor 13 is hermetically fixed on the right side of the cross pipe 12; the host computer is respectively connected to the control unit and the pressure sensor 4, and the control unit is respectively connected to the power supply module, the filter pressure reducing valve 7, the first solenoid valve 5, the second solenoid valve 6, and the vibration motor 1.

[0018] The above control unit can be a known PIC18F4620 control chip in the art; the host computer can be a known computer, laptop computer, etc.

[0019] When the present invention works, first, the movement 28 of the well inclination measuring instrument is hermetically fixed by threads at the lower end of the connecting pipe 10, so that the piston 11 in the connecting pipe 10 can enter the movement 28. Then, the inlet of the filter pressure reducing valve 7 is connected to the outlet of an external gas source generating device, the power supply module supplies power to the control unit, the host computer outputs a start instruction to the control unit, and the control unit controls the vibration motor 1 to start. After the vibration motor 1 vibrates, the specific process is as follows:

[0020] (1) Pressurization: The control unit controls the filter pressure reducing valve 7, the first solenoid valve 5, and the second solenoid valve 6 to open, the gas source applies hydraulic pressure to the test nipple 3, pressurizes the cylinder 2, collects the pressure through the pressure sensor 4, and maintains the pressure when the pressure reaches 60 psi (0.4 MPa);

[0021] (2)Pressure holding: The control unit first controls the second solenoid valve 6 to close, and then controls the first solenoid valve 5 to close to complete pressure holding.

[0022] (3)Differential pressure pulse signal measurement: After pressure holding is completed, the piston rod of the cylinder 2 pushes the piston 11 in the connecting pipe 10 downward into the movement mechanism 28. The piston 11 displaces downward twice to form two differential pressure pulse signals. After the pressure sensor 4 collects the pulse signals, they are output to the host computer for decoding to measure the differential pressure pulse signals generated during the operation of the well inclination measuring instrument.

[0023] (4)Actuating stroke measurement: During the test, when the piston rod of the cylinder 2 pushes the piston 11 downward, the displacement detection sensor 13 also moves accordingly. The displacement detection sensor 13 collects its own displacement to represent the displacement of the piston 11 in the movement mechanism 28, and is used to measure the actuating stroke of the valve rod of the well inclination measuring instrument.

[0024] During the above process, the whole device is vibrated by the vibration motor 1 to simulate the working state of the well inclination measuring instrument underground; the filter pressure reducing valve 7 is used to filter the air source.

[0025] In summary, in the present invention, by pressurizing the cylinder 2, the piston rod of the cylinder 2 pushes the piston 11 in the connecting pipe 10 to move. The displacement detection sensor 13 collects the displacement of the piston 11 to complete the measurement of the actuating stroke of the valve rod of the well inclination measuring instrument, and the pressure sensor 4 collects the differential pressure pulse signals to complete the measurement of the differential pressure pulse signals generated during the operation of the well inclination measuring instrument, realizing the precise test of the functions of the well inclination measuring instrument, with simple operation, low cost, and effectively improving the functional test efficiency of the well inclination measuring instrument.

[0026] According to actual needs, the above-mentioned test tool for the high-integration well inclination measuring instrument can be further optimized and / or improved:

[0027] As shown in the appendix Figure 1 It also includes a pressure gauge 14, and the pressure gauge 14 is fixedly installed on the test nipple 3 at the position between the second solenoid valve 6 and the pressure sensor 4.

[0028] By setting the pressure gauge 14 as above, it is convenient for on-site staff to directly read the pressure in the test nipple 3 from the pressure gauge 14.

[0030] The above-mentioned power indicator light 16 is used to indicate that the device is in the working process, preventing accidental touch and misoperation.

[0031] As mentioned above, by setting the timing display screen 22, after the vibration motor 1 starts, the control unit controls the timing display screen 22 to start timing. And after the control unit controls the second solenoid valve 6 and the first solenoid valve 5 to close in sequence, that is, when the pressure holding process starts, the control unit controls the timing display screen 22 to return to zero and start timing again, so that the pressure holding duration is about 2 minutes, which is used to measure the time required for a single data signal to be sent and received.

[0032] The above-mentioned automatic button 21 is used to control the control unit. On-site staff can directly press the automatic button 21 to conduct tests, so there is no need for the upper computer to output a start command to the control unit, which is convenient for on-site operation.

[0033] The above-mentioned vibration motor button 17 is used to start the vibration motor 1 before the test. The stationary button 18 is used to stop the vibration motor 1. The pressure application button 19 is used to control the opening and closing of the first solenoid valve 5.

[0035] As attached Figure 1 As shown in the figure, it further includes a test bracket. The test bracket includes a mounting plate 24 and a mounting bracket 25. The mounting bracket 25 is fixedly installed at the bottom of the mounting plate 24.

[0036] By setting the above-mentioned test bracket, it provides support for the entire test device, preventing the vibration of the vibration motor 1 during the test from driving the entire device to move, which is not convenient for the test work.

[0037] As attached Figure 1As shown, the base includes a horizontal fixed plate 26 and a vertical fixed plate 27. The rear side of the horizontal fixed plate 26 is fixedly connected to the upper side of the vertical fixed plate 27 to form an inverted "L" shape.

A through hole is provided on the upper side of the horizontal fixed plate 26, and the bottom of the connecting pipe 10 passes through the through hole and is located below the horizontal fixed plate 26.

[0038] With such a setting, it is convenient to fix the cylinder 2 and the vibration motor 1, and at the same time, it is convenient to fix them to the test bracket.
