Description

Technical Field

[0001] The invention relates to the technical field of directional drilling, and in particular to a mechanical selection control method for large longitudinal slope directional drilling. Background Art

[0002] A large longitudinal slope refers to a situation in which a line in a road, railway, or pipeline project has a large longitudinal slope along its length, and the large longitudinal slope is often accompanied by complex topography, such as gullies, rock protrusions, and landslides. Directional drilling technology is widely used in the fields of oil, natural gas, and urban infrastructure construction. However, when faced with a large longitudinal slope, the traditional directional drilling machinery selection method faces many challenges. Due to the large drilling angle, complex geological conditions, and high construction difficulty under the large longitudinal slope terrain, conventional machinery and equipment often cannot meet the requirements of accuracy, stability, and construction efficiency under these conditions. At present, most machinery selection relies on experience and simple theoretical calculations, and lacks a systematic control method. This approach may lead to improper machinery selection, which in turn affects the construction progress and even causes drilling failure. In addition, under the large longitudinal slope terrain, the selection and adjustment of machinery and equipment are crucial to the success of construction.

[0003] Secondly, when the existing mechanical selection exploration equipment is used to take soil samples in a large longitudinal slope environment, it is difficult to completely and comprehensively remove the sampled soil because the internal soil bag falls downward due to its own gravity when the sampling tube is pulled out upward. This makes it difficult for staff to accurately judge the texture distribution of the entire soil profile, and may misjudge the characteristics of the soil, resulting in deviations in the analysis structure.

[0004] Moreover, it is difficult for the mechanical selection exploration device to separately preserve the soil at different depths in the land. When the mechanical selection exploration device is taken out, part of the soil will be mixed due to adhesion during the process, resulting in deviations in the soil data detection, which makes it difficult to accurately reflect the true situation of the soil and affect the selection of directional drilling rigs. At the same time, when sampling the soil, it is difficult for ground tools to detect the soil pressure at different depths and can only perform pressure detection on the sparse soil in the mechanical selection exploration device, resulting in reduced accuracy of soil pressure in a large longitudinal slope environment, affecting the selection of mechanical equipment in directional drilling operations and extending the construction period. Therefore, the present application provides a mechanical selection control method for large longitudinal slope directional drilling to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a mechanical selection control method for large longitudinal slope directional drilling to solve the problem that when the existing device is performing soil sampling in a large longitudinal slope environment, it is difficult to accurately judge the texture distribution of the entire soil profile, and the soil characteristics may be misjudged, resulting in deviations in the analysis structure. In addition, it is difficult for the mechanical selection exploration device to preserve the soil at different depths in the land in a single manner. When the mechanical selection exploration device is taken out, the soil is in a mixed state, resulting in deviations in data detection, making it difficult to accurately reflect the true situation of the soil, affecting the selection of the directional drilling rig. At the same time, when sampling the soil, it is difficult for the ground tool to detect the soil pressure at different depths, and it can only perform pressure detection on the sparse soil in the mechanical selection exploration device, resulting in reduced accuracy of soil pressure in a large longitudinal slope environment, affecting the selection of mechanical equipment in directional drilling operations, extending the construction period, and reducing the accuracy of the operation.

According to the construction progress and real-time data, the mechanical selection is dynamically adjusted. If necessary, the mechanical equipment is replaced or adjusted to cope with sudden geological changes or mechanical failures.

[0055] As an implementation method in this embodiment, Figures 1 to 12As shown, the surface of the selected exploration equipment 1 is installed with a base 2, a hydraulic push rod 3 is installed on one side of the base 2, a push track 5 is installed on the output end of the hydraulic push rod 3, a control center 4 is installed on the top of the selected exploration equipment 1 away from the base 2, a push seat 9 is slidably connected to the surface of the push track 5, a motor 10 is installed on the top of the push seat 9, a rotating tube 11 is installed on the output end of the motor 10, and a drill bit 12 is installed at the bottom of the rotating tube 11; it also includes a sampling assembly 6, a sampling assembly 6 is installed at the bottom of the motor 10, and the sampling assembly 6 is used for sampling the different Soil at the same depth is collected; it includes a rotating sealing component 7, the surface of the rotating tube 11 is equipped with a rotating sealing component 7, and the rotating sealing component 7 is used to seal soil at different depths; it includes a detection and adjustment component 8, the inner wall of the rotating tube 11 is equipped with a detection and adjustment component 8, and the detection and adjustment component 8 is used to detect the pressure of soil layers at different depths; the interior of the collection and sampling component 6 is equipped with a rotating sealing component 7, and the bottom of the rotating sealing component 7 is equipped with a detection and adjustment component 8; the rotating tube 11 is connected to the output end of the motor 10, and a plurality of groups of holes are arranged on the surface of the rotating tube 11.

[0056] As an implementation method in this embodiment, Figures 4 to 10As shown, the sampling assembly 6 includes a power gear 61, which is mounted on the surface of the rotating tube 11. One end of the power gear 61 is meshedly connected with a driven gear 62. The driven gear 62 has two groups located at both ends of the power gear 61. One end of the driven gear 62 is meshedly connected with an inner-tooth rotating cylinder 63. The top of the inner-tooth rotating cylinder 63 is slidably connected with a turntable 64. A folded sampling tube 65 is mounted at the bottom of the inner-tooth rotating cylinder 63. A plurality of groups of holes are provided on the surface of the folded sampling tube 65. An inner blade tube 66 is mounted at the bottom of the folded sampling tube 65. The inner blade tube 66 The internal bevel blade of the drill bit 12 is opposite to the bevel blade of the drill bit 12. A lock buckle 67 is installed on the surface of the folded sampling tube 65. An oil tank 68 is installed at one end of the inner tooth rotating cylinder 63. The oil pipe at the bottom of the oil tank 68 is connected to the inner wall of the folded sampling tube 65. Before the motor 10 starts, the folded sampling tube 65 starts to close. Under manual observation, the lock buckle 67 installed on the surface is locked to prevent the folded sampling tube 65 from loosening during mining. Then the motor 10 is started to rotate. When the motor 10 starts to rotate, the rotating tube 11 installed at the output end of the motor 10 is synchronously moved. The sampling assembly 6 starts to rotate, and the rotating tube 11 rotates at the output end of the motor 10. The power gear 61 installed on the surface of the rotating tube 11 rotates in the same direction. When the power gear 61 starts to rotate, the driven gear 62 meshing on the surface starts to rotate. When the driven gear 62 also starts to rotate, the inner gear rotating cylinder 63 meshing on the surface of the driven gear 62 starts to rotate. At this time, the rotation direction of the inner gear rotating cylinder 63 is opposite to the rotation direction of the drill bit 12. At the same time, the inner gear rotating cylinder 63 continues to rotate on the turntable 64. At this time, the bottom of the folded sampling tube 65 The inner blade tube 66 rotates, and the inner blade and the rotation direction of the inner blade tube 66 are opposite to the rotation direction of the drill bit 12. After the soil is loosened, the inner blade tube 66 can quickly rotate and push the soil into the interior of the folded sampling tube 65 for transportation. When the folded sampling tube 65 is transported to the ground, the oil tank 68 continuously transports oil to the inner wall of the folded sampling tube 65. The transported oil overflows through the holes on the surface of the folded sampling tube 65 and directly contacts the soil to reduce the friction between the folded sampling tube 65 and the soil during the descent, thereby increasing the service life of the device.

[0057] As an implementation method in this embodiment, Figures 7 to 11As shown, the rotary sealing assembly 7 includes a receiving top plate 71, which is mounted on the surface of the rotating tube 11. The inner wall of the receiving top plate 71 is provided with a stepped groove, and the inner wall of the stepped groove is provided with a baffle. A spring 78 is installed on the top of the receiving top plate 71. A rotating disk 72 is provided above the receiving top plate 71. The rotating disk 72 is arranged in a stepped manner. Baffles are installed at both ends of the rotating disk 72. The size of the rotating disk 72 is smaller than the size of the stepped groove inside the receiving top plate 71, and the rotating disk 72 is arranged on the receiving top plate 71. On the moving track of plate 71, a bracket 73 is installed at the bottom of rotating disk 72, a connecting rod 74 is installed at the bottom of bracket 73, a blocking blade 75 is installed on the surface of connecting rod 74, the top of blocking blade 75 is slidably connected with a slide frame 76, and the bottom of blocking blade 75 is slidably connected with a circular frame 77. When the folded sampling tube 65 is dropped to the maximum depth, the soil sampled inside the folded sampling tube 65 will be pushed upward. At this time, under the push of the soil, the rotating sealing assembly 7 starts When the top plate 71 contacts the rotating disk 72, the baffle plates inside the top plate 71 and on the surface of the rotating disk 72 are staggered. At this time, the top plate 71 drives the rotating disk 72 to rotate. The rotation of the rotating disk 72 causes the bracket 73 to rotate synchronously. At the same time, the rotation of the bracket 73 causes the connecting rod 74 installed at the bottom to start moving. The connecting rod 74 is inserted into the slider at the top of each group of blocking blades 75. When the connecting rod 74 moves, the slider at the top of the blocking blade 75 starts to move in the slide frame 76, and the cylinder at the bottom of the blocking blade 75 also starts to move in the hole inside the circular frame 77. At this time, the blocking blade 75 slowly approaches the surface of the rotating tube 11 and stops after being completely fitted therewith. At this time, soil of different depths is divided into different chambers for storage.

[0058] As an implementation method in this embodiment, Figures 10 to 12As shown, the detection and adjustment component 8 includes a connecting pipe 81, which is installed at the bottom of the rotating disk 72. A moving seat 82 is installed on the outer surface of the connecting pipe 81, and a rack 83 is installed at the bottom of the moving seat 82. A rotating wheel 84 is meshed and connected on the surface of the rack 83. A force plate 85 is installed at one end of the rotating wheel 84. The length of the force plate 85 is half of the inner diameter of the rotating tube 11. The force plate 85 and the rotating wheel 84 have the same rotation trajectory. A liquid sensor 86 is installed inside the front end of the force plate 85, and a pull rope 87 is installed at one end of the force plate 85. A pressure sensor 88 is installed at the end of the pull rope 87 away from the force plate 85. The pressure sensor 88 is installed inside the rotating tube 11. After the rotary sealing component 7 seals soil at different depths, the top plate 71 pushes the rotating disk 72. The detection and adjustment component 8 starts to operate, and the connecting tube 81 is pulled. The pulling of the connecting tube 81 causes the movable seat 82 to move. When the movable seat 82 moves upward, the rack 83 also moves upward with the movable seat 82. The movement of the rack 83 drives the meshing connected rotating wheel 84 to rotate. At this time, the rotation of the rotating wheel 84 causes the force plate 85 to begin to flip on the inner wall of the rotating tube 11 into the cavity of the folded sampling tube 65. Since the soil has filled the entire chamber at this time, the liquid sensor 86 at the front end of the force plate 85 detects the moisture contained in the formation and transmits it to the control center 4. At the same time, the force generated by the force plate 85 during the flipping process continues to pull the pressure sensor 88 through the pull rope 87. When the pressure sensor 88 is subjected to the force of the pull rope 87, the generated data is synchronously transmitted back to the control center 4.

[0059] The working principle of the technical solution provided by the present invention is as follows:

[0060] First, move the selected exploration equipment 1 to the site with a large longitudinal slope, check the integrity of each device, and then start the hydraulic push rod 3 on the base 2 through the control center 4 to extend the diameter of the front end of the hydraulic push rod 3. When the hydraulic push rod 3 is extended, the output end of the hydraulic push rod 3 is connected to the push track 5 and is slowly turned by the front end rotating shaft of the selected exploration equipment 1 until it is perpendicular to the soil surface. Then stop the output of the hydraulic push rod 3, and at the same time, lower the support rods around the vehicle body to contact the ground to play a role of stable support. Then, make the front end of the push track 5 against the ground to keep it stable, and then start the motor 10 to rotate the rotating tube 11 at the output end of the motor 10. When the rotating tube 11 rotates, the drill bit 12 installed at the bottom of the rotating tube 11 rotates at the same time, and then start the pushing seat 9 to push the device slowly toward the soil.

[0061] Before the motor 10 starts, the folded sampling tube 65 starts to close. Under manual observation, the lock buckle 67 installed on the surface is locked to prevent the folded sampling tube 65 from loosening during mining. Then the motor 10 is started to rotate. When the motor 10 starts to rotate, the rotating tube 11 installed at the output end of the motor 10 rotates synchronously, and the sampling assembly 6 starts to rotate. At this time, the rotating tube 11 rotates at the output end of the motor 10, and the power gear 61 installed on the surface of the rotating tube 11 rotates in the same direction. When the power gear 61 starts to rotate, the driven gear 62 meshing with the surface starts to rotate. When the driven gear 62 also starts to rotate, the internal gear rotating cylinder 63 meshing with the surface of the driven gear 62 starts to rotate. At this time, the inner gear The rotation direction of the toothed rotating drum 63 is opposite to that of the drill bit 12, and the inner toothed rotating drum 63 continuously rotates on the turntable 64. At this time, the inner blade tube 66 at the bottom of the folded sampling tube 65 rotates, and the inner blade and the rotation direction of the inner blade tube 66 are opposite to the rotation direction of the drill bit 12. After the soil is loosened, the inner blade tube 66 can quickly rotate and push the soil into the interior of the folded sampling tube 65 for transportation, and while the folded sampling tube 65 is being transported to the ground, the oil tank 68 continuously transports oil to the inner wall of the folded sampling tube 65, and then the transported oil overflows through the holes on the surface of the folded sampling tube 65, and directly contacts the soil to reduce the friction between the folded sampling tube 65 and the soil during the descent process, thereby increasing the service life of the device.

[0062] When the folded sampling tube 65 is lowered to the maximum depth, the soil sampled inside the folded sampling tube 65 will be pushed upward. At this time, under the push of the soil, the rotary sealing assembly 7 starts to move, and the top plate 71 is pushed upward slowly by the soil. At this time, the spring 78 applies a reverse force. The reverse force of the spring 78 makes the soil inside the folded sampling tube 65 solid and then continues to push upward. When the top plate 71 contacts the rotating disk 72, the baffles inside the top plate 71 and on the surface of the rotating disk 72 are staggered. At this time, the top plate 71 drives the rotating disk 72 The rotation of the rotating disk 72 causes the bracket 73 to rotate synchronously. At the same time, the rotation of the bracket 73 causes the connecting rod 74 installed at the bottom to start moving. The connecting rod 74 is inserted into the slider at the top of each group of blocking blades 75. When the connecting rod 74 moves, the slider at the top of the blocking blade 75 starts to move in the slide frame 76, and the cylinder at the bottom of the blocking blade 75 also starts to move in the hole inside the circular frame 77. At this time, the blocking blade 75 slowly approaches the surface of the rotating tube 11 and stops after it is completely fitted therewith. At this time, soil of different depths is divided and stored in different chambers.

[0063] When the rotary sealing assembly 7 seals the soil at different depths, the top plate 71 pushes the rotating disk 72, the detection and adjustment assembly 8 starts to operate, the connecting pipe 81 is pulled, and the pulling of the connecting pipe 81 causes the movable seat 82 to move. When the movable seat 82 moves upward, the rack 83 also moves upward with the movable seat 82. The movement of the rack 83 drives the meshing connected rotating wheel 84 to rotate. At this time, the rotation of the rotating wheel 84 causes the force-bearing plate 85 to begin to flip on the inner wall of the rotating tube 11 into the cavity of the folded sampling tube 65. Since the soil has filled the entire chamber at this time, the liquid sensor 86 at the front end of the force-bearing plate 85 detects the moisture contained in the stratum and transmits it to the control center 4. At the same time, the force generated by the force-bearing plate 85 during the flipping process continues to pull the pressure sensor 88 through the pull rope 87. When the pressure sensor 88 is subjected to the force of the pull rope 87, the generated data is synchronously transmitted back to the control center 4, providing the staff with a reference for selection.
