Description

Technical Field

[0001] This invention relates to the field of probe testing devices, and more particularly to a wired drilling trajectory pressure measurement probe testing device and its usage method. Background Technology

[0002] Wired track-and-pressure measurement systems are commonly used in directional drilling operations in coal mines. The most critical component of the system is the track-and-pressure measurement probe, which measures the trajectory and pressure parameters at the bottom of the borehole. The measurement data is transmitted to the explosion-proof computer at the borehole opening via a dedicated cable drill rod and probe communication line. After data demodulation and processing, the trajectory and pressure parameters are displayed in real time. Drilling engineers adjust the direction and control the pump pressure based on the displayed parameters to complete the directional drilling according to the design requirements. At the same time, the borehole computer supplies power to the track-and-pressure measurement probe through the probe communication line and the cable drill rod.

[0003] Due to factors such as drilling depth, quality issues, wear and aging, and oxidation of connecting springs, wired drill pipes used for transmitting measurement data often experience problems such as poor data transmission, transmission failure, or excessive voltage drop in the power supply causing the probe to malfunction. The performance of the wired drilling trajectory pressure measurement probe directly affects the success of the measurement. Therefore, there is an urgent need to design a wired drilling trajectory pressure measurement probe testing device to test the performance of the drilling trajectory pressure measurement probe under different conditions.

[0004] The pressure value of the drilling trajectory pressure measurement probe is measured by a pressure sensor at the tail of the probe to measure the bottom hole pressure. Testing is typically conducted using a pressure test bench. During testing, the tail of the drilling trajectory pressure measurement probe is installed at one end of the test bench, and a pressure gauge is placed at the other end. The pressure of the test bench is adjusted, and the probe is connected to a computer via a communication cable to view the pressure value. The value is compared with the pressure gauge reading to determine if the error meets the standard requirements. This testing method cannot simulate the actual pressure values ​​under real-world operating conditions and cannot test the water pressure resistance of the drilling trajectory pressure measurement probe casing. Currently, there is no wired drilling trajectory pressure measurement probe testing device that can simultaneously perform communication and probe power supply simulation testing, pressure range testing, and casing water pressure resistance testing. Summary of the Invention

[0005] To address the problem that existing technologies cannot simultaneously test the communication and power supply performance of the probe, test the pressure range of simulated actual operating conditions, and test the water pressure resistance of the probe casing for drilling trajectory pressure measurement, this invention provides a wired drilling trajectory pressure measurement probe testing device and its usage method.

[0006] On the one hand, the present invention provides a wired drilling trajectory pressure measurement probe testing device, which adopts the following technical solution:

[0007] A wired drilling trajectory pressure measurement probe test device includes a test chamber, a test pump, and a communication test component. The output end of the test pump is sealed and connected to one end of a high-pressure hose, and the other end of the high-pressure hose is sealed and connected to the test chamber. The test chamber is connected to the communication test component via a communication line.

[0008] Furthermore, the test chamber includes a pressure chamber, and the side wall of the pressure chamber is provided with two connection holes, which are respectively connected to a vent valve and a pressure gauge by threads; the outer side wall of the pressure chamber is provided with a pressure boosting hole, which is connected to the inside of the pressure chamber; the opening of the pressure chamber is threaded with a sealing joint and sealed by a first O-ring.

[0009] Furthermore, the sealing joint includes an end and a connecting part. The outer surface of the connecting part is provided with a thread that mates with the opening of the pressure chamber. The sealing joint has a through hole for fixing the drilling trajectory pressure measurement probe. The drilling trajectory pressure measurement probe is installed in the through hole. One end of the drilling trajectory pressure measurement probe is provided with a probe communication end. The probe communication end is threaded into the through hole and sealed by a second O-ring. The other end of the drilling trajectory pressure measurement probe is provided with a pressure sensor.

[0010] Furthermore, the communication testing component includes a computer, a data processing board, a through-hole drill pipe simulator, a communication line, a positive terminal connection post, and a negative terminal connection post. The computer is connected to the data processing board via the communication line, and the data processing board is connected to the through-hole drill pipe simulator via the communication line. The through-hole drill pipe simulator is connected to the positive terminal connection post and the negative terminal connection post via the communication line. The positive terminal connection post extends into the through hole and is threadedly connected to the communication end of the probe inside the through hole. The negative terminal connection post is threadedly connected to the end of the sealing connector.

[0011] Furthermore, the cable drill pipe simulator includes four adjustable resistors, four adjustable inductors, and one adjustable capacitor. The adjustable resistors and adjustable inductors are connected in series to form an LR series circuit, and an adjustable capacitor is connected in parallel between the four LR series circuits.

[0012] Furthermore, the pressure testing pump is a manual pressure testing pump or an electric pressure testing pump;

[0013] Furthermore, the operating pressure range of the test pump is 0–30 MPa;

[0014] Furthermore, the pressure value of the high-pressure hose and pressure gauge is ≥30MPa;

[0015] Furthermore, the water pressure test range of the drilling trajectory pressure measurement probe is 0–12 MPa.

[0016] On the other hand, this application provides a method for using a wired drilling trajectory pressure measurement probe testing device, employing the following technical solution:

[0017] A method for using a wired drilling trajectory pressure measurement probe test device includes the following steps: S1: After connecting the drilling trajectory pressure measurement probe to the sealing joint, it is installed in the test chamber. The test pressure pump is connected to the test chamber through a high-pressure hose. The computer, data processing board, and cable drill pipe simulator are connected to the drilling trajectory pressure measurement probe through a communication line.

[0018] S2: Fill the test chamber with clean water, pressurize it with a test pump, set the pressure value according to the test value, turn on the computer, start the drilling trajectory pressure measurement software, and adjust it to display the normal pressure value. The error between the pressure value displayed by the software and the value displayed by the pressure gauge installed on the test chamber is within the standard allowable accuracy range.

[0019] S3: Adjust the pressure inside the test chamber until the pressure gauge shows a pressure of 12MPa. Hold the pressure for 20 minutes. If the pressure gauge value does not change, it confirms that the water pressure resistance of the outer shell meets the requirements.

[0020] S4: During the pressure holding process, adjust the four adjustable resistors R1 to R4, the four adjustable inductors L1 to L4, and the adjustable capacitor C1 respectively. The drilling trajectory pressure measurement software can normally display the inclination angle, azimuth angle, tool face angle, and pressure value. This can simulate the working conditions of the drilling trajectory pressure measurement probe under various working conditions such as different depths, cable drill pipe quality problems, water ingress due to wear and aging, and oxidation and loose connection of connecting springs.

[0021] S5: Depressurize the test chamber using the test pump, shut down the computer, disconnect the wiring, remove the drilling trajectory pressure measurement probe and wipe it clean.

[0022] In summary, the beneficial effects of this invention are as follows: By setting up an experimental chamber, a cable drill pipe simulator, and communication testing components, this invention can simulate various working conditions such as different depths, cable drill pipe quality problems, water ingress due to wear and aging, and oxidation and loose connection of connecting springs, and can test the communication and probe power supply performance, as well as the range of bottom hole pressure values; by setting up an experimental chamber and a pressure testing pump, the water pressure resistance performance of the probe shell for drilling trajectory pressure measurement can be tested.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The present invention will be further described in detail below:

[0031] This invention discloses a wired drilling trajectory pressure measurement probe testing device, such as... Figure 1 As shown, a wired drilling trajectory pressure measurement probe testing device of the present invention includes a test chamber 1, a pressure testing pump 5, and a communication testing component. The output end of the pressure testing pump 5 is sealed and connected to one end of a high-pressure hose 4, and the other end of the high-pressure hose 4 is sealed and connected to the test chamber 1. The test chamber 1 is connected to the communication testing component via a communication line 9. In this embodiment, by adding the test chamber 1 and the pressure testing pump 5, the high-pressure water-crossing working environment encountered by the drilling trajectory pressure measurement probe 16 during drilling can be simulated. By adjusting the output pressure of the pressure testing pump 5, the pressure encountered by the drilling trajectory pressure measurement probe 16 at different depths can be simulated. Preferably, the pressure testing pump 5 is a manual pressure testing pump or an electric pressure testing pump, the working pressure range of the pressure testing pump 5 is 0-30 MPa, and the pressure value that the high-pressure hose 4 can withstand is ≥30 MPa. By adding a communication test component, various working conditions can be simulated, such as different depths, quality problems of the cable-driven drill pipe, water ingress due to wear and aging, and oxidation and loose connection of the connecting spring. The communication and power supply performance of the drilling trajectory pressure measurement probe, the range of bottom hole pressure values, and the water pressure resistance performance of the drilling trajectory pressure measurement probe shell can be tested.

[0032] like Figure 1 , Figure 2 , Figure 4As shown, the experimental chamber 1 includes a pressure chamber 13. Two connection holes are provided on the side wall of the pressure chamber 13, each threadedly connected to a vent valve 2 and a pressure gauge 3, respectively. A pressure boosting hole is provided on the outer side wall of the pressure chamber 13, communicating with the interior of the pressure chamber 13. A sealing joint 12 is threadedly connected to the opening of the pressure chamber 13 and sealed by a first O-ring 14. In this embodiment, the pressure boosting hole on the side wall of the pressure chamber 13 is used to connect a high-pressure hose 4, which is sealed to the pressure boosting hole. The pressure provided by the pressure testing pump 5 enters the pressure chamber 13 through the pressure boosting hole. By adding the vent valve 2 and the pressure gauge 3, the reading of the pressure gauge 3 can be observed in real time to adjust the output pressure of the pressure testing pump 5, and the pressure in the pressure chamber 13 can be changed by the vent valve 2. Preferably, the pressure value of the pressure gauge 3 is ≥30MPa. The first O-ring 14 is located at the opening of the pressure chamber 13. When the sealing joint 12 is threadedly connected to the pressure chamber 13, the first O-ring 14 can achieve overall sealing and pressure bearing after connection.

[0033] like Figure 1 As shown, the sealing joint 12 includes an end 121 and a connecting part 122. The outer surface of the connecting part 122 is provided with threads that mate with the opening of the pressure chamber 13. The sealing joint 12 has a through hole for fixing the drilling trajectory pressure measurement probe 16. The drilling trajectory pressure measurement probe 16 is installed in the through hole. One end of the drilling trajectory pressure measurement probe 16 is provided with a probe communication end 17, which is threaded into the through hole and sealed by a second O-ring 18. The other end of the drilling trajectory pressure measurement probe 16 is provided with a pressure sensor. In this embodiment, the sealing joint 12 is a T-shaped frustum with a through hole in the middle that passes through the end 121 of the sealing joint 12 and the connecting part 122. The shape of the through hole matches the drilling trajectory pressure measuring probe 16 and the probe communication end 17. A thread that matches the probe communication end 17 is provided at the opening near the end 121 in the through hole. The second O-ring 18 is provided on the probe communication end 17. When the probe communication end 17 is connected to the through hole by the thread, the top of the probe communication end 17 will pass through the through hole. The second O-ring 18 can achieve overall sealing and pressure bearing after connection. A retaining ring is provided at the connection point 122 between the drilling trajectory pressure measurement probe 16 and the sealing joint 12. The retaining ring surrounds the outer wall of the drilling trajectory pressure measurement probe 16, and has two fixing holes on its surface. Two connecting screws 15 pass through these holes to bolt the retaining ring to the bottom of the connection point 122, thus fixing the drilling trajectory pressure measurement probe 16 inside the pressure chamber 13. The connection point between the connecting screws 15 and the sealing joint 12 is sealed with an O-ring to bear pressure. Figure 3 As can be seen, a stabilizer is also provided at the end of the drilling trajectory pressure measurement probe 16 near the pressure boosting hole. The stabilizer can ensure the straightness of the drilling trajectory pressure measurement probe 16.

[0034] like Figure 1 As shown, the communication test component includes a computer 6, a data processing board 7, a through-hole drill pipe simulator 8, a communication line 9, a positive terminal 10, and a negative terminal 11. The computer 6 is connected to the data processing board 7 via the communication line 9. The data processing board 7 is connected to the through-hole drill pipe simulator 8 via the communication line 9. The through-hole drill pipe simulator 8 is connected to the positive terminal 10 and the negative terminal 11 via the communication line 9. The positive terminal 10 is inserted into the through hole and threadedly connected to the probe communication end 17 inside the through hole. The negative terminal 11 is threadedly connected to the end 121 of the sealing connector. In this embodiment, by adding the through-hole drill pipe simulator 8, various working conditions such as different depths, through-hole drill pipe quality problems, water ingress due to wear and aging, and oxidation and loose connection of the connecting spring can be simulated. The positive terminal 10 is threaded to the communication end 17 of the probe, and the negative terminal 11 is threaded to the end 121 of the sealing connector. The two transmit the data collected by the drilling trajectory pressure measurement probe 16 through the communication line 9 and the cable drill pipe simulator 8 to the computer 6 and the data processing board 7. After data demodulation processing, the two display the trajectory and pressure parameters in real time.

[0035] like Figure 5 As shown, the cable-through drill pipe simulator 8 includes four adjustable resistors, four adjustable inductors, and one adjustable capacitor. The adjustable resistors and adjustable inductors are connected in series to form an LR series circuit, and an adjustable capacitor is connected in parallel between the four LR series circuits. In this embodiment, the four adjustable resistors R1-R4 and the four adjustable inductors L1-L4 are connected in series to form four LR series circuits, and the adjustable capacitor C1 is connected in parallel between the four LR series circuits. By adjusting the four adjustable resistors R1-R4, the four adjustable inductors L1-L4, and the adjustable capacitor C1, various working conditions can be simulated, such as different depths, cable-through drill pipe quality problems, water ingress due to wear and aging, and oxidation and loose connection of connecting springs.

[0036] like Figure 1 As shown, the water pressure resistance range of the drilling trajectory pressure measurement probe 16 is 0 to 12 MPa. In this embodiment, the drilling trajectory pressure measurement probe 16 should withstand a pressure of 12 MPa for 20 minutes in a test chamber 1 filled with water. If the pressure gauge value does not change, it is determined that the water pressure resistance of the outer shell meets the requirements.

[0037] The implementation principle of this invention is as follows: When the wired drilling trajectory pressure measurement probe test device provided by this invention is working, it follows the... Figures 1-4Connect the drilling trajectory pressure measurement probe, pipeline, and wiring. Place the drilling trajectory pressure measurement probe 16 into the test chamber 1 and inject clean water into the test chamber 1. Pressurize the chamber using the test pressure pump 5. Keep the vent valve 2 in the open position. After the gas is completely expelled, tighten the vent valve and observe the pressure value displayed on the pressure gauge 3. When the test value is reached, open the drilling trajectory pressure measurement software on the computer 6. The difference between the displayed pressure value and the pressure gauge value should meet the measurement tolerance required by the standard. Adjust the test value sequentially to complete the test. The probe's water pressure resistance requirement is 12MPa. Adjust the pressure gauge value to reach 12MPa and maintain the pressure for 20 minutes. If the pressure gauge value does not change, it is confirmed that the shell's water pressure resistance meets the requirements.

[0038] The method of using the wired drilling trajectory pressure measurement probe test device of the present invention includes the following steps:

[0039] S1: Insert the drilling trajectory pressure measurement probe 16 into the through hole of the sealing joint 12. The probe communication end 17 is threaded into the through hole and sealed by the second O-ring 18. After connection, it is installed in the pressure chamber 13 inside the test chamber 1. The output end of the test pressure pump 5 is connected to the pressure boosting hole on the side wall of the pressure chamber 13 through the high pressure hose 4. The computer 6 is connected to the data processing board 7 and the cable drill rod simulator 8 in sequence through the communication line 9, and finally connected to the positive terminal 10 connected to the probe communication end 17 and the negative terminal 11 connected to the sealing joint 12 respectively.

[0040] S2: Water is injected into the test chamber 1 and pressurized by the test pump 5. The pressure value is set according to the test value. In this embodiment, the test value is adjusted step by step according to the test values ​​of 0 MPa, 5 MPa, 10 MPa and 12 MPa. The computer 6 is turned on and the drilling trajectory pressure measurement software is started. The software is adjusted to display the pressure value normally, and the error between the pressure value displayed by the software and the value displayed by the pressure gauge 3 installed on the test chamber 1 is within the standard allowable accuracy range. After multiple adjustments without error, the test can be started.

[0041] S3: Adjust the pressure inside test chamber 1 until the pressure gauge 3 shows a pressure of 12MPa. Hold the pressure for 20 minutes. If the pressure gauge 3 value does not change, it is confirmed that the water pressure resistance of the outer shell meets the requirements.

[0042] S4: During the pressure holding process, adjust the four adjustable resistors R1 to R4, the four adjustable inductors L1 to L4, and the adjustable capacitor C1 respectively. The drilling trajectory pressure measurement software can normally display the inclination angle, azimuth angle, tool face angle, and pressure value. This can simulate the working conditions of the drilling trajectory pressure measurement probe 16 under various working conditions such as different depths, cable drill pipe quality problems, water ingress due to wear and aging, and oxidation and loose connection of connecting springs.

[0043] S5: Depressurize the test chamber 1 by using the test pressure pump 5, shut down the computer 6, disconnect the circuit connection, take out the drilling trajectory pressure measurement probe 16 and wipe it clean.
