Technical Field

[0001] This invention relates to the field of oil drilling testing instruments, and in particular to a dynamic measuring device for engineering parameter measurement tools. Background Technology

[0002] In rotary steerable drilling technology, engineering parameter measuring tools are lowered into the ground along with the rotary steerable tool for drilling operations. Driven by the rotary steerable tool, the engineering parameter measuring tools rotate synchronously with it. During downhole operation, the rotary steerable tool continuously contacts the formation, generating vibrations that affect subsequent connected tools, including the engineering parameter measuring tools. To test the performance of the engineering parameter measuring tools, dynamic calibration is necessary. Existing testing devices can only test the performance of these tools at fixed angles such as 0°, 45°, and 90°, resulting in incomplete experimental data and low accuracy. Therefore, to address these shortcomings, a dynamic measuring device for engineering parameter measuring tools is proposed. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", "top", and "bottom" are based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this invention and to simplify the description. It is not intended to indicate or imply that the component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0022] like Figure 1-4 As shown, the present invention provides a dynamic measuring device for engineering parameter measuring tools, specifically comprising: The device comprises a vibration table 9 and a base 1, with the vibration table 9 mounted below the base 1. The base 1, as the main body of the device, primarily serves to bear and support loads, and is used to mount other components within the device. The vibration table 9 itself generates vibration and transmits this vibration to other components within the device, causing the entire device to vibrate synchronously with the vibration table 9, simulating tool vibration in the downhole working environment. During operation, the frequency and amplitude of tool vibration change depending on the working conditions. The vibration amplitude of the vibration table 9 can be controlled to adjust the operating environment, ensuring the device's operating environment matches the downhole working environment and improving the accuracy of dynamic measurements. The base 1 has a support plate 10 at its top, with its bottom hinged to the edge of the base 1. After hinged to the base 1, the support plate 10 can open and close along its connection point. When a tool is mounted on the support plate 10, the tool can be tilted at an angle to the horizontal plane by opening and closing the support plate 10 and controlling the opening and closing amplitude.

[0023] A tripod 14 is provided between the supporting base plate 10 and the base 1. The bottom end of the tripod 14 is fixed to the base 1, and the top end is hinged to the supporting base plate 10. The longitudinal section of the tripod 14 is triangular. Connecting the supporting base plate 10 and the base 1 through the tripod 14 simplifies the installation steps between the base 1 and the supporting base plate 10 and reduces the installation difficulty of the supporting base plate 10 and the base 1.

[0024] It should be noted that a shock-absorbing pad 16 is provided between the bottom end of the support base plate 10 and the top end of the base 1. The shock-absorbing pad 16 is generally made of rubber and plays a role in shock absorption and buffering between the support base plate 10 and the base 1, preventing the support base plate 10 from colliding with the top end of the base 1 when the support base plate 10 is frequently opened and closed, thus preventing damage to the support base plate 10 and the base 1 and extending the service life of the device.

[0025] In this invention, a hydraulic support arm 7 is provided inside the base 1. The fixed end of the hydraulic support arm 7 is connected to the base 1, and the movable end is connected to the bottom end of the support plate 10. The hydraulic support arm 7 lifts the support plate 10 upwards and controls the lifting height. The hydraulic support arm 7 is used to control the opening and closing of the support plate 10. When the hydraulic support arm 7 extends its movable end outwards, the movable end pushes the support plate 10 upwards, causing the support plate 10 to open and causing the components mounted on the support plate 10 to tilt and form an angle with the ground. Before the hydraulic support arm 7 moves, the extension amount of the hydraulic support arm 7 can be adjusted by controlling the power source of the hydraulic support arm 7. After the movable end of the hydraulic support arm 7 is extended, it can remain stable, thereby fixing the position of the support plate 10 and the tool mounted on the support plate 10, making the measured data more accurate and stable, and realizing the measurement of any angle during the measurement process.

[0026] The base 1 has a fixing frame 15 at its inner bottom end. The fixing frame 15 is connected to the fixed end of the hydraulic arm 7 and is fixedly connected to the base 1. The fixing frame 15 functions similarly to the tripod 14. While connecting the hydraulic arm 7 to the base 1, it reduces the workload during connection. If the connection between the base 1 and the hydraulic arm 7 becomes loose, only the fixing frame 15 needs to be replaced or tightened, without the need for repeated disassembly of the base 1 and the hydraulic arm 7.

[0027] like Figure 1-4 As shown, a stepper motor 2 and a centralizer 13 are mounted on the support base plate 10, with a parameter measuring tool 5 positioned between the stepper motor 2 and the centralizer 13. The parameter measuring tool 5, as the object being tested, is lifted by the support base plate 10 during measurement, forming an angle with the ground. The centralizer 13 and the stepper motor 2 are located at opposite ends of the parameter measuring tool 5, clamping it onto the support base plate 10. The output end of the stepper motor 2 is connected to the parameter measuring tool 5. After starting the stepper motor 2, the parameter measuring tool 5 rotates around its axis between the centralizer 13 and the stepper motor 2, simulating the rotation of the parameter measuring tool 5 along with the rotary guide tool during downhole operation. Combined with the vibration table 9, this allows for complete simulation of the downhole working environment. Meanwhile, by controlling the output power of the stepper motor 2, the rotation speed of the parameter measuring tool 5 can be changed. While adjusting the rotation speed of the stepper motor 2, the vibration frequency and amplitude of the vibration table 9 can be adjusted, which can simulate most working conditions downhole, thereby improving the accuracy of the measurement data.

[0028] The centralizer 13 is equipped with wires that connect the parameter measuring tool 5 to the control system. The control system receives data measured by the tool within the device and processes the received data. The parameter measuring tool 5 has an upper connector 4 and a lower connector 11 at its upper and lower ends, respectively. The upper connector 4 and lower connector 11 are used to connect to the stepper motor 2 and the centralizer 13, respectively. The upper connector 4 and lower connector 11 can fit tightly with the parameter measuring tool 5, eliminating the need to modify the connection between the stepper motor 2 and the centralizer 13 to fit the parameter measuring tool 5, thus ensuring a stable connection between the parameter measuring tool 5 and the stepper motor 2 and the centralizer 13.

[0029] It should be noted that a universal joint 3 is provided between the upper connector 4 and the stepper motor 2, and the lower connector 11 and the centralizer 13 are connected via a rotary connector. The universal joint 3 can bend in any direction while rotating, acting as a buffer between the upper connector 4 and the stepper motor 2 to prevent damage to the upper connector 4 from severe vibration and rotation. During operation, the universal joint 3 will slightly bend in the direction of greater bending force due to vibration and rotation, thus providing a buffering effect. When the rotary connector connects the lower connector 11 and the centralizer 13, it allows for the transmission of power and signals between the two devices without affecting their relative rotation. The rotary connector includes a female connector 21 and a male connector 20. The female connector 21 is fixed to the centralizer 13, and the male connector 20 is fixed to the lower connector 11. The end of the female connector 21 is connected to the power supply and control system. The male connector 20 is connected to the parameter measuring tool 5 through the lower connector 11. After the male connector 20 contacts the female connector 21, the data measured in the parameter measuring tool 5 is transmitted to the control system through the male connector 20 and the female connector 21. The power supply provides power to the parameter measuring tool 5 through the male connector 20 and the female connector 21.

[0030] To improve the stability of the device, multiple straight-lined straight-lined rings 6 are evenly arranged on the support base plate 10 between the stepper motor 2 and the straightener 13. The parameter measuring tool 5 passes through the straight-lined rings 6. The straight-lined rings 6 support and limit the parameter measuring tool 5, fixing it on the straight line between the stepper motor 2 and the straightener 13, preventing the parameter measuring tool 5 from shifting position. When the parameter measuring tool 5 is long, the middle position of the parameter measuring tool held by the stepper motor 2 and the straightener 13 will bend and deform downward under the action of gravity. When the stepper motor 2 drives the parameter measuring tool 5 to rotate, it is easy to cause irreversible damage to the parameter measuring tool 5. The straight-lined rings 6 support the parameter measuring tool 5 upward, preventing it from deforming under the action of gravity, thereby avoiding damage to the parameter measuring tool 5. A bearing 19 is provided between the inner wall of the straight-lined ring 6 and the parameter measuring tool 5. The bearing 19 is located between the straightening ring 6 and the parameter measuring tool 5, which avoids direct contact between the straightening ring 6 and the parameter measuring tool 5, reduces the friction between the straightening ring 6 and the parameter measuring tool 5, and reduces the wear on the side wall when the parameter measuring tool 5 rotates.

[0031] like Figure 2-4As shown, an angle sensor 12 is installed on the support base 10. The angle sensor 12 and the parameter measuring tool 5 move with the support base 10. When the support base 10 is raised, the angle sensor 12 can measure its current tilt angle. At this time, the measurement result of the angle sensor 12 is not affected by the rotational motion, and the measurement result is correct. After comparing the measurement result of the parameter measuring tool 5 with the measurement result of the angle sensor 12, the accuracy of the parameter measuring tool 5 can be determined based on the difference between the measurement results of the parameter measuring tool 5 and the angle sensor 12. The vibration table 9, stepper motor 2, hydraulic support arm 7, parameter measuring tool 5, and angle sensor 12 are all connected to the control system. The control system controls the output power of the power source and the stepper motor 2 and receives the measurement signals from the parameter measuring tool 5 and the angle sensor 12. During the performance testing of parameter measurement tool 5, the extension of the hydraulic support arm is adjusted by the control system to position the support base plate 10 at the target well angle. Then, the stepper motor 2 is started, and the readings of parameter measurement tool 5 and angle sensor 12 are read. According to the work plan, the working states of vibration table 9, stepper motor 2, and hydraulic support arm 7 are continuously adjusted to change the vibration state, rotation state, and tilt angle of the device. After receiving the readings from parameter measurement tool 5 and angle sensor 12, the control system compares the two to determine the working performance of parameter measurement tool 5. The closer the measurement result of parameter measurement tool 5 is to the measurement result of angle sensor 12, and the smaller the difference between the two measurement results, the better the working performance of parameter measurement tool 5.

[0032] The supporting base plate 10 is provided with a sensor clamping block 17, and the angle sensor 12 is fixed on the sensor clamping block 17. The sensor clamping block 17 is used to fix the angle sensor 12. By clamping the angle sensor 12 with the sensor clamping block 17, the tightening and processing of the angle sensor 12 can be avoided, reducing wear on the angle sensor 12 and extending the service life of the device.

[0033] Meanwhile, a shock-absorbing ring 18 is provided between the inner wall of the sensor clamping block 17 and the angle sensor 12. The shock-absorbing ring 18 is generally made of elastic materials such as rubber, which can balance the influence of vibration on the angle sensor 12 during operation and reduce the impact of vibration on the measurement results of the angle sensor 12.

[0034] In this invention, since the device will vibrate continuously under the drive of the vibration table 9 during measurement, in order to strengthen the device structure and prevent the connections of various components from loosening under the influence of vibration during operation, the straightening ring 6, the straightener 13, the sensor clamping block 17 and the vibration table 9 are fixedly connected to the base 1 by fixing bolts 8.

[0035] The dynamic measurement device for engineering parameter measuring tools provided by this invention can evaluate the working status of the parameter measuring tool under different tilt angles, rotational speeds, and vibration amplitudes. The specific operation process of this device is as follows: Step 1: After assembling the device according to its structure, clamp the parameter measuring tool between the straightening ring and the stepper motor.

[0036] Step Two: The control system extends the hydraulic outrigger, starts the stepper motor, and reads the readings from the parameter measuring tool and angle sensor. Simultaneously, the operating states of the stepper motor, vibration table, and hydraulic outrigger are continuously adjusted. During this process, under the adjustment of the control system, the vibration amplitude, vibration frequency, and rotation speed of the parameter measuring tool constantly change, causing the tool's operating conditions to continuously change. At the same time, the parameter measuring tool and angle sensor continuously measure their own angles and send the measurement results to the control system for recording.

[0037] Step 3: Compare the measurement results of the parameter measuring tool and the angle sensor recorded in the control system, and judge the working performance of the parameter measuring tool based on the difference between the measurement results of the parameter measuring tool and the angle sensor.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
