[0001] This invention relates to the field of drilling auxiliary measurement and control technology, specifically to a rotary steering measurement and control stabilization platform and measurement and control system based on electromagnetic damper adjustment. Background Technology

[0002] The measurement and control stabilization platform is a measurement and control device used in oil drilling. Its function is to ensure that the monitoring platform is not affected by the rotation of the drill string during drilling. It works with the command system of the rotary steerable drilling system to adjust the tool face angle of the steerable tool in real time during drilling to achieve the steerable function.

[0003] Early measurement and control stabilization platforms adopted a dual-motor structure, with the upper turbine generator providing downhole power and the lower turbine generator providing control torque. This approach resulted in a complex structure and large size. Adjusting the torque of the lower turbine generator by adjusting the load resistance was inconvenient for heat dissipation. The control process was cumbersome, the braking torque was small, and the failure rate was high. Summary of the Invention

The second rotor is coaxially spaced on the outer side of the second stator. The lower turbine sleeve is coaxially fitted on the outer side of the lower isolation cover and is rotatably connected to the lower isolation cover via bearings.

[0009] The beneficial effects of this invention are as follows: The rotary guiding and control stabilization platform based on electromagnetic damper adjustment utilizes an electromagnetic coupler to achieve non-contact torque transmission between the turbine sleeve and the damper; moreover, the upper and lower isolation covers serve as sealing components, creating a good sealing environment for the internal pressure regulating damper, balancing damper, and generator. Furthermore, the pressure regulating damper and balancing damper are electromagnetic dampers, possessing advantages such as non-contact operation, linear control, and high braking efficiency. Compared to the existing dual-generator structure which occupies a large space, this invention, during the adjustment of the torque applied to the stabilization platform, converts the kinetic energy of the mud into heat energy generated by the regulating and balancing dampers, which is distributed on the rotor of the dampers, resulting in better braking and heat dissipation effects.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, it also includes an upper end cover and a lower end cover, the upper end cover being installed at the end of the upper isolation cover opposite to the platform body, and the lower end cover being installed at the end of the lower isolation cover opposite to the platform body.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the setting of the upper end cover and the lower end cover is conducive to sealing the end of the turbine sleeve.

[0013] Furthermore, it also includes a base sleeve, which is sleeved on the outside of the platform body, and the two ends of the base sleeve are fixedly connected to the upper isolation cover and the lower isolation cover through a first connector and a second connector, respectively.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the base sleeve helps to seal the inside of the measurement and control stabilization platform, and facilitates the installation and setup of electronic components.

[0015] Furthermore, the helical direction of the blades of the upper turbine sleeve is opposite to that of the blades of the lower turbine sleeve.

The detection sensor is installed on the platform body and detects the actual value of the preset deflection parameter of the platform body.

[0021] The upper turbine sleeve and the lower turbine sleeve rotate under the impact of mud. The upper turbine sleeve transmits power to the first rotor of the voltage regulating damper through the upper magnetic coupler. The first rotor drives the generator rotor to rotate. The lower turbine sleeve transmits power to the second rotor of the balance damper through the lower magnetic coupler.

[0022] The control module is used to adjust the maximum deviation of the actual value of the preset deflection parameter within a preset time period to the preset difference range corresponding to the preset deflection parameter by adjusting the first actual voltage across the balance damper and the second actual voltage across the voltage regulating damper.

[0023] The beneficial effects of this invention are as follows: The measurement and control system of this invention is convenient to control. It uses an electromagnetic damper to achieve the braking effect. Compared with the traditional dual-motor design, it only uses one generator, resulting in a simpler structure. The generator outputs three-phase AC power, which is rectified by a rectifier bridge to output DC power for use by the voltage regulating damper and the stabilizing and balancing damper. DC power control is convenient. The voltage regulating damper and the stabilizing and balancing damper are electromagnetic dampers, which have the advantages of non-contact operation and high braking efficiency, simplifying the system structure, improving the system braking efficiency, and increasing the system braking torque. This invention uses a magnetic coupler to achieve non-contact torque transmission, and uses the upper isolation cover and the lower isolation cover as sealing components to create a good sealing environment for the internal voltage regulating damper, stabilizing and balancing damper, and generator, thereby improving the system's sealing performance.

[0024] Furthermore, the control module is specifically used to: based on the actual value of the preset deflection parameter and the preset difference range corresponding to the preset deflection parameter, use the PID method to adjust the first actual voltage across the balance damper and the second actual voltage across the voltage regulating damper until the maximum deviation of the actual value of the preset deflection parameter within a preset time period is adjusted to the preset difference range corresponding to the preset deflection parameter.

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] like Figures 1-4 As shown, the rotary guide measurement and control stabilization platform based on electromagnetic damper adjustment in this embodiment includes an upper turbine sleeve 6, an upper magnetic coupler 5, a pressure regulating damper 4, an upper isolation cover 2, a generator 7, a lower turbine sleeve 15, a lower isolation cover 16, a lower magnetic coupler 13, a balance damper 14, and a platform body 9.

The lower magnetic coupler 13 is connected to the lower turbine sleeve 6 and the balance damper 14 respectively and transmits the power of the lower turbine sleeve 6 to the balance damper 14.

[0033] The voltage regulating damper 4 includes a first rotor 19 and a first stator 21 arranged opposite to each other; the balancing damper 14 includes a second rotor 12 and a second stator 22 arranged opposite to each other; the generator 7 includes a generator rotor and a generator stator arranged opposite to each other; the two ends of the platform body 9 are fixedly connected to the first stator 21 and the second stator 22 respectively in the axial direction; wherein, the generator rotor is a magnet, the generator stator includes a stator coil and a motor shaft 3, the stator coil is fixed on the motor shaft 3, and the motor shaft 3 is fixedly connected to the first stator 21, as shown below. Figure 2 As shown, Figure 2 The boxes drawn in the text are for easy indication of the structure of the damper, coupler, and generator.

[0034] The first stator 21 is covered with an upper isolation cover 2. The first rotor 19 is coaxially mounted on the inner wall of the upper isolation cover 2 via bearings. The first rotor 19 is coaxially spaced on the outer side of the first stator 21. The upper turbine sleeve 6 is coaxially spaced on the outer side of the upper isolation cover 2 and is rotatably connected to the upper isolation cover 2 via bearings. The generator stator is fixed on the first stator 21, and the generator rotor is fixed on the inner wall of the first rotor 19.

[0035] The second stator 22 is covered with a lower isolation cover 16. The second rotor 12 is coaxially mounted on the inner side wall of the lower isolation cover 16 through a bearing. The second rotor 12 is coaxially spaced on the outer side of the second stator 22. The lower turbine sleeve 15 is coaxially spaced on the outer side of the lower isolation cover 16 and is rotatably connected to the lower isolation cover 16 through a bearing.

[0036] Specifically, in this embodiment, both the upper turbine sleeve 6 and the lower turbine sleeve 15 adopt a cylindrical structure. The upper isolation cover 2 and the lower isolation cover 16 also adopt a cylindrical structure.

[0037] like Figure 1 and Figure 2 As shown, the rotary guide measurement and control stabilization platform of this embodiment also includes an upper end cover 1 and a lower end cover 17. The upper end cover 1 is installed on the end of the upper isolation cover 2 opposite to the platform body 9, and the lower end cover 17 is installed on the end of the lower isolation cover 16 opposite to the platform body 9. A piston ring 18 is also provided on the lower end cover 17 for sealing the connection between the lower end cover 17 and the connecting shaft on the second stator 22. The upper end cover 1 and the lower end cover 17 facilitate sealing the end of the turbine sleeve.

[0038] like Figure 1 and Figure 2As shown, the rotary guide measurement and control stabilization platform of this embodiment also includes a base sleeve 11. The base sleeve 11 is sleeved on the outside of the platform body 9, and both ends of the base sleeve 11 are fixedly connected to the upper isolation cover 2 and the lower isolation cover 16 through a first connector 8 and a second connector 20, respectively. An annular cavity 10 is formed between the base sleeve and the platform body 9 for assembling electronic components, etc. The base sleeve helps to seal the inside of the measurement and control stabilization platform and facilitates the installation and setup of electronic components.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the blade helix direction of the upper turbine sleeve 6 is opposite to the blade helix direction of the lower turbine sleeve 15.

[0040] like Figure 2 and Figure 3 As shown, the first stator 21 of the voltage regulating damper 4 in this embodiment has a first annular groove in the middle, and a first stator coil is fixed in the first annular groove.

[0041] like Figure 2 and Figure 3 As shown, the second stator 22 of the balance damper 14 in this embodiment has a second annular groove in the middle, and a second stator coil is fixed in the second annular groove.

[0042] like Figure 2 As shown, the upper magnetic coupler 5 in this embodiment includes a first inner permanent magnet and a first outer permanent magnet arranged opposite to each other. The first outer permanent magnet is fixed on the inner side wall of the upper turbine sleeve 6, and the first inner permanent magnet is fixed on the outer side wall of the first rotor 19.

[0043] like Figure 2 As shown, the lower magnetic coupler 13 in this embodiment includes a second inner permanent magnet and a second outer permanent magnet arranged opposite to each other. The second outer permanent magnet is fixed on the inner side wall of the lower turbine sleeve 15, and the second inner permanent magnet is fixed on the outer side wall of the second rotor 12.

[0044] In this embodiment, the first outer permanent magnet of the upper magnetic coupler is fixedly installed on the inner surface of the upper turbine sleeve, and the first inner permanent magnet of the upper magnetic coupler is fixedly installed on the outer surface of the first rotor of the pressure regulating damper. Utilizing the interaction force between the inner and outer permanent magnets, non-contact torque transmission is achieved between the upper turbine sleeve and the pressure regulating damper rotor. When the mud impacts the upper turbine sleeve, it rotates, driving the first rotor of the pressure regulating damper to rotate via the upper magnetic coupler. In this embodiment, the second outer permanent magnet of the lower magnetic coupler is fixedly installed on the inner surface of the lower turbine sleeve, and the second inner permanent magnet of the lower magnetic coupler is fixedly installed on the outer surface of the second rotor of the balance damper. When the mud impacts the lower turbine sleeve, it rotates, driving the second rotor of the balance damper to rotate via the lower magnetic coupler. In this embodiment, the upper and lower turbine sleeves have the same blade shape but are installed in opposite directions. During operation, the mud impacts the upper and lower turbine sleeves, causing them to rotate in opposite directions. The balancing damper applies torque to the measurement and control stabilization platform. The torque generated by the generator and voltage regulating damper on the measurement and control stabilization platform is equal in magnitude but opposite in direction to the torque generated by the stabilizing balancing damper, allowing adjustment of the platform's rotational speed and stabilization angle. The upper and lower isolation covers serve as sealing components, creating a good sealing environment for the internal voltage regulating damper, stabilizing balancing damper, and generator. The generator outputs three-phase AC power, which is rectified by a rectifier bridge to output DC power for use by the voltage regulating damper and stabilizing balancing damper, facilitating DC power control. The voltage regulating damper and stabilizing balancing damper are electromagnetic dampers, possessing advantages such as non-contact operation, linear control, and high braking efficiency.

[0045] This embodiment of the rotary steering and control stabilization platform based on electromagnetic damper adjustment utilizes an electromagnetic coupler to achieve non-contact torque transmission between the turbine sleeve and the damper. Furthermore, upper and lower isolation covers serve as sealing components, creating a favorable sealing environment for the internal pressure regulating damper, balancing damper, and generator. Moreover, the pressure regulating damper and balancing damper are electromagnetic dampers, offering advantages such as non-contact operation, linear control, and high braking efficiency. Compared to the existing dual-generator structure which occupies a large space, this embodiment of the rotary steering and control stabilization platform, during the adjustment of the torque applied to the platform, converts the kinetic energy of the mud into heat energy generated by the regulating and balancing dampers, which is distributed on the rotor of the dampers, resulting in better braking and heat dissipation effects.

[0046] This embodiment also provides a measurement and control system, including the rotary guide measurement and control stabilization platform based on electromagnetic damper adjustment, and further including a control module and a detection sensor. The control module is electrically connected to the detection sensor, the voltage regulating damper 4, the balance damper 14, and the generator stator, respectively. Figure 4As shown; the detection sensor is installed on the platform body 9 and detects the actual value of the preset deflection parameter (preset rotation speed or preset stability angle) of the platform body; wherein, the conversion relationship between the preset deflection parameter and voltage can be manually fitted according to historical deflection parameter and voltage data to obtain the functional relationship between the deflection parameter and voltage, and calibrated according to the functional relationship, or it can be manually calibrated according to experience.

[0047] The upper turbine sleeve 6 and the lower turbine sleeve 15 are rotated by the impact of mud. The upper turbine sleeve 6 transmits power to the first rotor of the voltage regulating damper 4 through the upper magnetic coupler 5. The first rotor 19 drives the generator rotor to rotate. The lower turbine sleeve 15 transmits power to the second rotor of the balance damper 14 through the lower magnetic coupler 13.

[0048] The control module is used to adjust the maximum deviation of the actual value of the preset deflection parameter within a preset time period to the preset difference range corresponding to the preset deflection parameter by adjusting the first actual voltage across the balance damper and the second actual voltage across the voltage regulating damper.

[0049] Furthermore, the control module is specifically used to: based on the actual value of the preset deflection parameter and the preset difference range corresponding to the preset deflection parameter, use the PID method to adjust the first actual voltage across the balance damper and the second actual voltage across the voltage regulating damper until the maximum deviation of the actual value of the preset deflection parameter within a preset time period is adjusted to the preset difference range corresponding to the preset deflection parameter.

[0050] The control module is also used to convert the three-phase power output from generator 7 into DC power through a rectifier bridge, and to adjust the magnitude of the first and second actual voltages via PWM. The three-phase AC power output from the generator is rectified by the rectifier bridge to output DC power to supply the voltage regulating damper and the balancing damper, making DC power control convenient.

[0051] In this embodiment, when the upper turbine sleeve 6 rotates due to mud impact, it drives the first rotor of the voltage regulating damper to rotate via the upper magnetic coupler 5. The three-phase AC power output by the generator 7 is rectified by the rectifier bridge and supplied to the voltage regulating damper 4 and the balancing damper 14. When the lower turbine sleeve 15 rotates due to mud impact, it drives the second rotor of the balancing damper to rotate via the lower magnetic coupler 13. The balancing damper 14 generates braking torque on the platform body 9. The torque generated by the generator 7 and the voltage regulating damper 4 on the platform body 9 is equal in magnitude and opposite in direction to the torque generated by the balancing damper 14 on the measurement and control stabilization platform 9, thus stabilizing the measurement and control stabilization platform. The voltage regulating damper 4 controls and offsets the power fluctuations of the mud pump, thereby reducing the voltage fluctuations of the generator 7 and improving the quality of the generator 7.

[0052] The generator 7 outputs three-phase AC power, which is rectified by the rectifier bridge and then supplied to the voltage regulating damper 4 and the balancing damper 14. The torque generated by the voltage regulating damper 4 on the platform body 9 is equal in magnitude and opposite in direction to the torque generated by the balancing damper 14 on the platform body 9, thereby stabilizing the platform body 9. The preset voltage UR2 of the voltage regulating damper 4 and the preset voltage UR1 of the balancing damper are set. The three-phase power output by the generator is converted into DC power through the rectifier bridge. The voltage magnitude is changed by PWM regulation. The balancing damper 14 generates a braking torque T1 on the platform body 9. The torque T2 generated by the balancing damper on the platform body 9 is equal in magnitude and opposite in direction when the platform body 9 is stable, so as to achieve the stability of the platform body 9 (the deflection angle or rotation speed is within the preset range). Specifically, the control module compares the second actual voltage UO2 at both ends of the voltage regulating damper with UR2 to obtain ΔU2, and compares the first actual voltage UO1 at both ends of the balancing damper 14 with UR1 to obtain ΔU1. When the platform body reaches stability, the voltage difference ΔU1 and ΔU2 are reduced to 0. This method occupies less space and can be easily implemented.

[0053] Figure 4 The control block diagram for the generator output voltage is given. Figure 4 The damper in the design can be either a pressure-regulating damper or a balancing damper. When the damper is a pressure-regulating damper, the turbine sleeve is the upper turbine sleeve; when the damper is a balancing damper, the turbine sleeve is the lower turbine sleeve. Figure 4 It can be seen that the initial adjustment process is as follows: the preset voltage of the voltage regulating damper is set to UR2, the upper turbine sleeve applies driving torque to the platform body, and the generator inputs the second actual voltage Uo2 to the voltage regulating damper. The coefficient k2 represents the adjustment coefficient. The cyclic adjustment process is as follows: UR2 and Uo2 are compared by the control module to obtain ΔU2, and then the second actual voltage Uo2 input by the generator to the voltage regulating damper is adjusted by the PID method. The same adjustment method is used to adjust the first actual voltage Uo1 input by the generator to the balance damper, and the voltage difference ΔU1 and ΔU2 are reduced to 0.

[0054] In drilling operations, the tool facet angle and its duration of action required for tool guidance, calculated using a preset trajectory and the actual trajectory, constitute the setpoint for platform stabilization control. The difference between this setpoint and the signal detected by the parameter sensor serves as the input signal for control calculations, controlling the calculation results. A controllable torque is provided by the balancing damper 14, achieving closed-loop control. During drilling, the turbine sleeve and generator below the platform generate positive torque. The control shaft of the platform body is rigidly connected to the stator of the balancing damper 14; when its rotor rotates, it generates a certain electromagnetic torque. The negative torque of the platform body comes from the frictional torque on the connecting bearings, the electromagnetic torque of the adjusting damper 4, and the electromagnetic torque of the generator 7, which rotates in the opposite direction. The presence of the reverse torque causes the platform body to rotate in the same direction as the drill string. By changing the current of the balancing damper 14 and the adjusting damper 4 through the control module, the total torque applied to the platform body 9 can be adjusted. Changing the sum of the torques acting on the platform body 9 allows for the adjustment of the platform's rotational speed and stability angle.

[0055] The measurement and control system in this embodiment is easy to control. It uses an electromagnetic damper to achieve the braking effect. Compared with the traditional dual-motor design, it only uses one generator, which simplifies the structure. The generator outputs three-phase AC power, which is rectified by a rectifier bridge to output DC power for the voltage regulating damper and the stabilizing and balancing damper. The DC power control is convenient. The voltage regulating damper and the stabilizing and balancing damper are electromagnetic dampers, which have the advantages of non-contact operation and high braking efficiency. This simplifies the system structure, improves the system braking efficiency, and enhances the system braking torque. This embodiment uses a magnetic coupler to achieve non-contact torque transmission. The upper isolation cover and the lower isolation cover are sealed components, creating a good sealing environment for the internal voltage regulating damper, stabilizing and balancing damper, and generator, thus improving the system's sealing performance.

The control module is electrically connected to the detection sensor, the voltage regulating damper, the balance damper, and the generator stator, respectively. The detection sensor is installed on the platform body and detects the actual value of the preset deflection parameter of the platform body. The upper turbine sleeve and the lower turbine sleeve rotate under the impact of mud. The upper turbine sleeve transmits power to the first rotor of the voltage regulating damper through the upper magnetic coupler. The first rotor drives the generator rotor to rotate. The lower turbine sleeve transmits power to the second rotor of the balance damper through the lower magnetic coupler. The control module is used to adjust the maximum deviation of the actual value of the preset deflection parameter within a preset time period to the preset difference range corresponding to the preset deflection parameter by adjusting the first actual voltage across the balance damper and the second actual voltage across the voltage regulating damper.

9. The measurement and control system according to claim 8, characterized in that, The control module is specifically used to: based on the actual value of the preset deflection parameter and the preset difference range corresponding to the preset deflection parameter, use the PID method to adjust the first actual voltage across the balance damper and the second actual voltage across the voltage regulating damper until the maximum deviation of the actual value of the preset deflection parameter within a preset time period is adjusted to the preset difference range corresponding to the preset deflection parameter.
