Description

Technical Field

[0001] The invention relates to a deflection correction tool detection system and belongs to the technical field of oil and gas development. Background Art

[0002] In order to solve the problem of anti-deflection and fast drilling in high-steep structures, large-angle formations and other easily deflected strata faced by deep oil and gas development, various deflection correction drilling tools have been developed. Before the tools are put into use, it is necessary to confirm the actual performance of the deflection correction tools under harsh working conditions downhole, such as the palm extension sensitivity of the deflection correction tool, palm displacement, and the functional relationship between palm force and circulating fluid pressure and flow rate. This requires a reliable detection system to fully test the tools before use, and optimize the deflection correction tools based on the test data to ensure the performance and reliability of the deflection correction tools.

[0003] Most of the existing technologies only conduct static tests such as hydrostatic sealing, tension and compression to evaluate the deflection correction tools. The test process does not match the actual working conditions such as well inclination angle, tool rotation speed, circulating fluid flow rate, pressure, etc. In addition, the structure of the downhole deflection correction tool itself is complex, and it is difficult to simulate the actual downhole working conditions by establishing an accurate theoretical model. As a result, the support palm of the deflection correction tool cannot be effectively extended and retracted during use, or the displacement and support force of the support palm are too large, resulting in tool support pressure, sticking, and severe wear of the palm.

[0046] Its Figure 8 As shown in the figure, the hydraulic control system is mainly composed of a dedicated transformer, a soft starter, a hydraulic pump, a hydraulic cooling system, a hydraulic oil tank, a motor, etc. The dedicated transformer supplies power to the soft starter, which starts and stops the hydraulic pump motor. The motor drives the hydraulic pump to provide hydraulic power to the motor, driving the motor to rotate.

[0047] Combination Fig. 9 The principle of the data acquisition and control system of the detection system is further explained. The data acquisition and control system of the detection system consists of a sensor detection device, a junction box, a multi-core cable, a camera, a network cable, a router, a hydraulic system, a motor, a bottom drive device, a lower computer, a host computer (server), an equipment-side operating table, a detection system control room, and a cross-regional command center. The multi-sensor detection device realizes one-input and multiple-output through the junction box, and transmits the sensor data to the lower computer through a multi-core cable. The data is processed by the lower computer and then uploaded to the host computer to realize data acquisition and storage; multiple cameras are connected to the router via a network cable, and multiple cameras are connected to the host computer to realize video data acquisition and storage; the hydraulic system provides power to the motor, and then drives the bottom drive device to rotate, thereby driving the tool to be tested to rotate. The speed and other signals collected by the sensor are processed by the lower computer and the host computer to realize closed-loop control of the motor, so that the bottom drive device can obtain a stable target speed.

[0048] It is further explained that the detection system is designed with three control points, namely the equipment-side operating table, the detection system control room, and the cross-regional command center; the equipment-side operating table enables the test equipment to debug the detection equipment under no-pressure conditions, or to rotate at low speed after installing the tool to be tested, and the operator can operate and confirm the working status of the equipment while close to the equipment; the detection system control room is a control room specially built at the location of the detection equipment. The control room is a closed room with bulletproof glass windows, which is convenient for detection personnel to operate safely when the equipment is under pressure and realize the inherent safety of the detection operation; the third control end is the cross-regional command center server and display screen. After connecting to the upper computer server, real-time remote control, remote decision-making, remote viewing of detection data and detection videos, and playback of data and videos are realized in the command center for data analysis and decision-making.

[0049] Combination Fig.10 Further explaining the sensor detection device, the sensor detection device is mainly composed of a liquid level sensor 401, a tool inlet pressure sensor 402, an angle sensor 403, an azimuth sensor 404, a tool outlet pressure sensor 405, a force-displacement sensor 406, and a speed torque sensor 407; the detection system detects the real-time operating parameters of the tool 7 to be tested through sensors such as displacement, pressure, angle, azimuth, force-displacement, speed torque, etc.

When the piston rod 411 moves back and forth, the distance at which the sensing rod of the displacement sensor 409 overlaps with the cavity of the piston rod 411 generates different current signals to measure the displacement of the piston rod; the spring 410 has a reset effect, so that the piston rod 411 pushes the force sensor 412 to further push the force measuring palm 413, so that the force measuring palm 413 is close to the surface of the tool to be tested; the force-displacement sensor realizes feedback of the tool palm force while measuring the displacement.
