Description

Technical Field

[0002] Horizontal directional drilling rig is a kind of construction machinery that can drill holes according to the designed curve without excavating the ground surface and successfully avoid obstacles within a certain radius underground. It is suitable for a variety of geological conditions, such as sand and clay. It can be constructed without excavating the ground. It is used for laying a variety of underground public facilities, such as pipelines and cables. It is also widely used in the laying of flexible pipelines for water supply, electricity, telecommunications, natural gas, coal gas, and oil.

[0003] When the existing directional drilling rig is in operation, due to the presence of mud and impurities at the threaded connection of the drill pipe, the connection speed of the drill pipe is affected when the drill pipe is threaded, and at the same time, the wear between the drill pipes is increased, and even the drill tool is damaged and deformed, which may also cause the drill pipe connection to fall off and slip. At the same time, when each drill pipe is connected, there is a lack of lubrication of lubricating oil, which causes greater friction when the drill pipe is connected, accelerates the wear of the drill pipe, causes scratches, increases the probability of failure, causes damage to the pipe, and affects the progress of the project. At the same time, the mud on the surface of the drill pipe is likely to increase the friction between the drill pipe and the soil, increase the resistance to advancement, slow down the speed of drilling, and affect the efficiency of construction.

[0004] Therefore, the present application provides a directional drilling guidance precision control system and method that is resistant to geomagnetic interference to meet the needs. Summary of the invention

[0016] The present application also provides another technical solution: a method for using a directional drilling guidance precision control system that is resistant to geomagnetic interference, comprising the following steps:

[0017] S1: Multi-sensor data fusion module: The system integrates multiple sensors, including gyroscopes, accelerometers, magnetometers, and inertial measurement units. Each sensor collects physical parameters during the drilling process, such as the angle, acceleration, and magnetic field strength of the drill bit, in real time. This module uses a data fusion algorithm to comprehensively analyze the data information from different sensors to obtain more accurate and stable drill bit attitude and position data;

[0018] S2: Geomagnetic interference detection and compensation module: This module is designed to detect data from the magnetometer in real time and identify abnormal interference signals in the geomagnetic field. By comparing the normal geomagnetic field model, the system can determine whether the current geomagnetic data is interfered with. Once interference is detected, the system will start the adaptive filtering algorithm to filter and compensate for the interference signal. The algorithm combines historical data and current environmental parameters to dynamically adjust the compensation strategy to ensure the accuracy of the guidance data;

[0019] S3: Direction calculation module: This module uses the comprehensive data provided by the multi-sensor data fusion module and applies the optimized attitude solution algorithm to calculate the precise direction and attitude of the drill bit in real time. The system also uses adaptive filters and Kalman filters to further improve the accuracy of direction calculation, especially in the case of abnormal geomagnetic field or large data fluctuations;

[0020] S4: Automatic calibration module: The system is equipped with an automatic calibration function, which can automatically adjust the sensor sensitivity and data processing parameters according to the sensor feedback information in different geological environments. The automatic calibration module can identify and correct sensor drift problems caused by changes in external conditions such as temperature, pressure, and vibration, thereby ensuring the long-term stability and reliability of the data;

[0021] S5: Real-time monitoring and feedback module: The system displays the current position, direction and related environmental parameters of the drill bit in real time through a graphical user interface or other monitoring means. Once the system detects that the guidance deviation exceeds the preset threshold, the real-time monitoring module will immediately issue an alarm and make instant adjustments to the drill bit through the control algorithm to correct the drilling trajectory.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In the above scheme, by setting up a cleaning and adjusting component, utilizing the cooperation among the servo motor, the main gear, the slave gear, the gear swivel seat, the telescopic rod, the piston rack, the nozzle, the threaded brush, the rotating chamber and the piston cylinder, the cleaning and adjusting component can be in the first operating chamber. The surface of the front end threaded connecting rod of the drill pipe and the internal thread of the rear end of the drill pipe are cleaned, and the impurities in the thread are flushed by the water source of the nozzle. At the same time, the threaded brush removes impurities that are difficult to clean, thereby keeping the drill pipe connection clean and tidy, facilitating the connection of adjacent drill pipes, reducing the connection time, reducing the wear during the connection of the drill pipe, avoiding damage and deformation of the drill tool due to the presence of impurities, and avoiding the risk of the drill pipe falling off in the formation.

[0024] By setting up an alternating positioning component and utilizing the slide rod, the first operating chamber, the second operating chamber, the correction seat, the pulley and the elastic seat, the cleaning and lubrication processes of the device can be divided into different tasks, thus avoiding the cumbersome process operations. At the same time, the division of labor and cooperation in the operating chamber speeds up the construction time, and the positioning and correction of the drill pipe by the correction seat speeds up the connection between two adjacent drill pipes, thus avoiding the wear of the drill pipe caused by forced connection and mismatch, preventing the occurrence of safety hazards, and saving the cost caused by wear.

[0025] By setting up a lubrication and impurity removal component, and utilizing a trigger rod, a lever, a bracket, a push rod, an annular oil chamber, an oil nozzle, a fixed elastic plate and an annular scraper, when the second operating chamber rises to the position of the first operating chamber, the drill pipe connection can be lubricated with lubricating oil, thereby reducing the friction between two adjacent drill pipes when connected, and reducing the wear of the drill pipe during construction. The spraying of lubricating oil speeds up the connection time, speeds up the drilling speed, reduces the probability of failure, increases the accuracy of the drill bit direction, avoids the occurrence of safety hazards, speeds up the progress of engineering construction, and improves the efficiency of construction.

[0046] As an implementation method in this embodiment, Figures 6 to 8As shown, the cleaning and adjusting component 6 includes a servo motor 61, which is arranged inside the lifting box 11, and a main gear 62 is installed at the output end of the servo motor 61, and a slave gear 63 is meshed and connected at the bottom of the main gear 62, and a gear rotating seat 64 is meshed and connected at the bottom of the slave gear 63, and a telescopic rod 65 is arranged at one end of the gear rotating seat 64, and a piston rack 66 is installed on the surface of the telescopic rod 65, and a threaded brush 68 is installed at one end of the piston rack 66, and a nozzle 67 is arranged on one side of the threaded brush 68, and a piston cylinder 610 is sleeved on the surface of the telescopic rod 65 at the other end of the gear rotating seat 64, and a rotating chamber 69 is installed at one end of the piston cylinder 610, and a threaded brush 68 and a nozzle 67 are arranged on the surface of the rotating chamber 69. When the drill pipe 4 moves to the inside of the lifting box 11, the cleaning and adjusting component 6 starts to run, and at this time, the servo motor 61 starts to start, and the output end of the servo motor 61 starts to rotate, which drives the output end The main gear 62 rotates. When the main gear 62 rotates, the slave gear 63 meshing at the bottom rotates after the torque of the main gear 62 is changed. The rotation of the slave gear 63 drives the gear rotating seat 64 at the bottom of the slave gear 63 to start rotating. When the gear rotating seat 64 starts to rotate, the telescopic rods 65 installed at both ends of the gear rotating seat 64 start to perform telescopic movement. When the telescopic rod 65 performs telescopic movement, the piston frame 66 and the piston cylinder 610 installed at the front end of the telescopic rod 65 perform telescopic movement synchronously. At this time, the threaded brush 68 and the nozzle 67 move in parallel and rotate at the same time. The rotating chamber 69 installed at one end of the piston cylinder 610 is at the tail end of the drill pipe 4, and the threads in the drill pipe 4 are horizontally flushed, and the rotation brushing is performed at the same time. The piston frame 66 at the other end flushes the surface of the threaded joint of the drill pipe 4 and also performs left and right washing to ensure the cleanliness of the connection.

[0047] As an implementation method in this embodiment, Figures 7 to 10As shown, the alternating positioning assembly 7 includes a slide bar 71, which is slidably connected to the interior of the lifting box 11, a first operating cavity 72 is installed at one end of the slide bar 71, a second operating cavity 73 is installed at the bottom of the first operating cavity 72, the first operating cavity 72 and the second operating cavity 73 are both provided with openings, and the sizes of the openings are consistent with the diameter of the drill pipe 4, a correction seat 74 is provided inside the second operating cavity 73, the correction seat 74 is a trapezoidal base, an elastic seat 76 is installed inside the correction seat 74, and a pulley 75 is installed at one end of the elastic seat 76, the slide bar 71 slides upward in the slide groove on the inner wall of the lifting box 11, and at this time the first operating cavity 72 is opened. 2 drives the second operating chamber 73 to move upward synchronously. When the first operating chamber 72 moves upward, the opening at the bottom of the first operating chamber 72 moves away from the drill pipe 4. At this time, the second operating chamber 73 begins to slowly approach the drill pipe 4. When the second operating chamber 73 slowly approaches the drill pipe 4, the correction seat 74 begins to contact the surface of the drill pipe 4. Through the inclination of the surface of the correction seat 74, the drill pipe 4 is closely attached to the inner wall of the correction seat 74 and fixed to the middle. At the same time, the pulley 75 assists the movement of the drill pipe 4, and the elastic seat 76 at one end of the pulley 75 bears the force brought by the drill pipe 4 and reacts to the pulley 75 so that the drill pipe 4 can move in the middle position.

[0048] As an implementation method in this embodiment, Figures 9 and 10As shown, the lubrication and impurity removal component 8 includes a trigger rod 81, the bottom of the trigger rod 81 is rotatably connected to a lever 82, a bracket 83 is installed in the middle of the lever 82, a push rod 84 is installed at one end of the lever 82, an annular oil chamber 85 is installed on the top of the push rod 84, the diameter of the annular oil chamber 85 is larger than the drill pipe 4, a fixed elastic plate 87 is installed at one end of the push rod 84, an oil nozzle 86 is installed on the inner wall of the annular oil chamber 85, an annular scraper 88 is installed on the inner wall of one end of the second operating chamber 73, the inner wall of the annular scraper 88 fits the outer surface of the drill pipe 4, when the front end outer surface of the drill pipe 4 touches the trigger rod 81, the trigger rod 81 starts to move slowly downward, the slow movement of the trigger rod 81 drives the lever 82 connected to the bottom end of the trigger rod 81 to rotate, when the lever 82 is subjected to the force applied by the trigger rod 81, the lever 82 flips on the bracket 83, when the lever 82 flips on the bracket 83 When the push rod 84 is rotated, the push rod 84 at the other end of the lever 82 moves. Since the push rod 84 moves parallel to the bottom surface of the second operating chamber 73, when the push rod 84 is lifted by the lever 82, the push rod 84 moves parallel to the bottom surface of the second operating chamber 73. When the push rod 84 moves, the fixed elastic plate 87 connected to one end of the push rod 84 is pulled. At the same time, the annular oil chamber 85 at the top of the push rod 84 moves following the moving direction of the push rod 84. At this time, the oil nozzle 86 sprays. When the annular oil chamber 85 moves, the oil nozzle 86 continues to spray from one end of the threaded joint of the drill pipe 4 to the other end of the threaded joint and stops. When the spraying is finished, the drill pipe 4 starts to continue to be transported and starts to connect with the tail of another drill pipe 4. When the drill pipe 4 passes through the second operating chamber 73, the annular scraper 88 scrapes off the impurities on the outer surface of the drill pipe 4. When the impurities are scraped off the surface of the drill pipe 4 by the annular scraper 88, the impurities fall off into the recovery bin 17 for collection.

[0049] The working principle of the technical solution provided by the present invention is as follows:

[0050] First, move the vehicle body 1 to the construction position, check the integrity of the device, confirm the position of the hole to be drilled, adjust the angle direction of the drill bit 13 in the connection box 12, fix the anchor drill 16, and then check through the control center 5 whether the data sent back by the gyroscope 14 and the accelerometer 15 are normal. After confirmation, start the device, unload the pipe rack 2 and push the drill pipe 4 to the track 10. At this time, the power seat 3 starts to push on the track 10. When the power seat 3 moves, the push head 9 at the front end of the power seat 3 moves synchronously. When the push head 9 moves, it begins to contact the tail of the drill pipe 4, and the push head pushes the tail of the drill pipe 4 to slide on the track 10 to the inside of the lifting box 11.

[0051] When the drill pipe 4 moves to the inside of the lifting box 11, the cleaning adjustment component 6 starts to operate. At this time, the servo motor 61 starts to start, and the output end of the servo motor 61 starts to rotate, which drives the main gear 62 at the output end to rotate. When the main gear 62 rotates, the slave gear 63 engaged at the bottom rotates after the torque of the main gear 62 is changed. The rotation of the slave gear 63 drives the gear rotating seat 64 at the bottom of the slave gear 63 to start rotating. When the gear rotating seat 64 starts to rotate, the telescopic rods 65 installed at both ends of the gear rotating seat 64 start to telescope. When the telescopic rod 65 telescopes, the piston frame 6 installed at the front end of the telescopic rod 65 6 and the piston cylinder 610 perform telescopic movement synchronously. At this time, the thread brush 68 and the nozzle 67 move in parallel and rotate at the same time. The rotating chamber 69 installed at one end of the piston cylinder 610 is at the tail of the drill pipe 4, and the threads in the drill pipe 4 are horizontally flushed, and the rotating brush is performed at the same time, while the piston frame 66 at the other end flushes the surface of the threaded joint of the drill pipe 4 and also washes left and right to ensure the cleanliness of the connection. When the front and rear ends of the drill pipe 4 are cleaned, the servo motor 61 stops. At this time, the telescopic rod 65 is tightened, and the piston frame 66 and the piston cylinder 610 are away from the drill pipe 4. At this time, the alternating positioning assembly 7 starts to operate.

[0052] When the alternating positioning assembly 7 starts to operate, the slide bar 71 slides upward in the slide groove on the inner wall of the lifting box 11. At this time, the first operating chamber 72 drives the second operating chamber 73 to move upward synchronously. When the first operating chamber 72 moves upward, the opening at the bottom of the first operating chamber 72 moves away from the drill pipe 4. At this time, the second operating chamber 73 begins to slowly approach the drill pipe 4. When the second operating chamber 73 slowly approaches the drill pipe 4, the correction seat 74 begins to contact the surface of the drill pipe 4. Through the inclination of the surface of the correction seat 74, the drill pipe 4 is closely attached to the inner wall of the correction seat 74 and fixed to the middle. At the same time, the pulley 75 assists the movement of the drill pipe 4, and the elastic seat 76 at one end of the pulley 75 bears the force brought by the drill pipe 4, and reacts to the pulley 75 so that the drill pipe 4 can maintain the middle position and move. At this time, after the tail of the drill pipe 4 is corrected, the front end of the other drill pipe 4 contacts the lubrication and impurity removal assembly 8, causing it to start running.

[0053] When the front end outer surface of the drill pipe 4 touches the trigger rod 81, the trigger rod 81 starts to move slowly downward. The slow movement of the trigger rod 81 drives the lever 82 connected to the bottom end of the trigger rod 81 to rotate. When the lever 82 is subjected to the force applied by the trigger rod 81, the lever 82 flips on the bracket 83. When the lever 82 flips on the bracket 83, the push rod 84 at the other end of the lever 82 moves. Since the push rod 84 moves parallel to the bottom surface of the second operating chamber 73, when the push rod 84 is lifted by the lever 82, the push rod 84 moves parallel. When the push rod 84 moves, the fixed elastic plate 87 connected to one end of the push rod 84 is pulled. At the same time, the annular oil chamber 85 at the top of the push rod 84 moves following the moving direction of the push rod 84. At this time, the oil nozzle 86 sprays. When the annular oil chamber 85 moves During movement, the oil nozzle 86 continuously sprays from one end of the threaded joint of the drill pipe 4 to the other end of the threaded joint and stops. When the spraying is finished, the drill pipe 4 starts to continue to be transported and starts to connect with the tail of another drill pipe 4. When the drill pipe 4 passes through the second operating chamber 73, the annular scraper 88 scrapes the impurities on the outer surface of the drill pipe 4. When the impurities are scraped off the surface of the drill pipe 4 by the annular scraper 88, the impurities fall into the recovery bin 17 for collection. At the same time, when the drill pipe 4 moves, it is continuously corrected by the pulley 75 on the correction seat 74. When the tail of the drill pipe 4 is in the position of the correction seat 74, the fixed elastic plate 87 pulls the push rod 84 back. At this time, the lever 82 starts to flip, the trigger rod 81 rises, and the slide rod 71 starts to move downward inside the lifting box 11. The first operating chamber 72 cleans the next group of drill pipes 4 again.

[0054] The present application also provides another technical solution: a method for using a directional drilling guidance precision control system that is resistant to geomagnetic interference, comprising the following steps:

[0055] S1: Multi-sensor data fusion module: The system integrates multiple sensors, including gyroscope 14, accelerometer 15, magnetometer, and inertial measurement unit. Each sensor collects physical parameters in the drilling process in real time, such as the angle, acceleration, and magnetic field strength of the drill bit 13. This module uses a data fusion algorithm to comprehensively analyze the data information from different sensors, thereby obtaining more accurate and stable drill bit 13 posture and position data;

[0056] S2: Geomagnetic interference detection and compensation module: This module is designed to detect data from the magnetometer in real time and identify abnormal interference signals in the geomagnetic field. By comparing the normal geomagnetic field model, the system can determine whether the current geomagnetic data is interfered with. Once interference is detected, the system will start the adaptive filtering algorithm to filter and compensate for the interference signal. The algorithm combines historical data and current environmental parameters to dynamically adjust the compensation strategy to ensure the accuracy of the guidance data;

[0057] S3: Direction calculation module: This module uses the comprehensive data provided by the multi-sensor data fusion module and applies the optimized attitude solution algorithm to calculate the precise direction and attitude of the drill bit 13 in real time. The system also uses adaptive filters and Kalman filters to further improve the accuracy of direction calculation, especially in the case of abnormal geomagnetic field or large data fluctuations;

[0058] S4: Automatic calibration module: The system is equipped with an automatic calibration function, which can automatically adjust the sensor sensitivity and data processing parameters according to the sensor feedback information in different geological environments. The automatic calibration module can identify and correct sensor drift problems caused by changes in external conditions such as temperature, pressure, and vibration, thereby ensuring the long-term stability and reliability of the data;

[0059] S5: Real-time monitoring and feedback module: The system displays the current position, direction and related environmental parameters of the drill bit 13 in real time through a graphical user interface or other monitoring means. Once the system detects that the guidance deviation exceeds the preset threshold, the real-time monitoring module will immediately issue an alarm and make real-time adjustments to the drill bit 13 through a control algorithm to correct the drilling trajectory.
