Description

Technical Field

[0001] The present invention relates to a sampling device and method for geological exploration in the technical field of intelligent detection devices for oil sand mines. Background Art

[0002] Sampling devices for geological exploration are key tools for geological surveys, mineral exploration, and environmental monitoring. In recent years, significant innovations have been made in aspects such as stratified sampling, portability, and function integration. Oil sand ore is a mixture of debris or rock in the earth's crust and the water and bitumen contained therein, belonging to unconventional petroleum resources. The purpose of sampling oil sand ore is to evaluate the bitumen content, ore grade, and resource recoverability. Usually, due to the complexity of the composition of oil sand ore and different geological conditions, the hardness at different depths of the sampling site will be different.

[0003] When the existing sampling device samples oil sand ore, it drills through a drill pipe and a drill bit. The drilled core enters the drill pipe, and then the core is taken out from the drill pipe to complete the sampling. However, when the existing device is in use, the drill bit will pass through different hardness strata, and the rotation speed and pressure applied by the sampling device to the drill bit are fixed. When the drill bit encounters a stratum with higher hardness, the drilling efficiency will be reduced. Summary of the Invention

[0007] Preferably, it further includes: a communication shell, which is fixedly connected to the mounting frame. The communication shell is communicated with the sliding shell. The sliding shell is used to supply water to the transfer member, thereby cooling the drill pipe and the drill bit. The communication shell is communicated with a water supply device; an adjusting plate, which is slidably connected to the communication shell. The adjusting plate is used to adjust the communication area of the communication shell.

[0008] Preferably, it further includes: a first housing fixedly connected to the mounting frame; a first sliding member slidably connected to the first housing, the first sliding member passing through the first housing and fixedly connected to the adjusting plate.

[0013] Preferably, the damping in the vertical direction between the plugging ring and the drill pipe is greater than the circumferential damping.

[0014] A usage method of a sampling device for geological exploration, based on the above sampling device for geological exploration, specifically includes the following steps: S1: First, start the driving device, adjust the position of the mounting frame, then install the drill pipe and the drill bit by threading, and after the connection is completed, start the motor, and the motor drives the drill bit to rotate; S2: Then start the water supply device, make water enter the communication housing, then enter the sliding housing through the hose, and then flow out from the drill bit through the intermediate member, the connecting member, and the drill pipe. After that, the driving device drives the drill bit to move downward for sampling; S3: When the resistance received by the drill bit increases, at this time, the mounting frame drives the motor to move downward relative to the friction wheel, changes the transmission position between the conical pulley and the friction wheel, and increases the rotation speed of the friction wheel; S4: At the same time, the mounting frame drives the second housing to move downward relative to the second sliding member, drives the adjusting plate to move upward, thereby increasing the communication area of the communication housing, and further increasing the water inflow; S5: When the drill bit drills to the oil sand ore, the resistance to the rotation of the drill bit increases, and the transmission adjusting plate moves upward, thereby increasing the amount of water flowing out of the drill bit to cool the oil sand ore; S6: Before the sampling is completed, cryogenic liquid is added through the inlet of the storage shell. After the sampling is completed, the drill pipe drives the sealing ring to move upward by friction, so that the sealing ring releases the sealing of the spray port on the storage shell. Then, the cryogenic liquid in the storage shell sprays from the spray port to the drill pipe to cool the drill pipe; S7: When the sampling is completed, turn off the motor and the water supply device, and make the driving device drive the mounting frame to move upward. The mounting frame drives the drill pipe and the drill bit to move out of the drill hole. Then, separate the connecting piece, the drill pipe and the drill bit respectively, take out the core in the drill pipe, and then establish a physical model for monitoring the oil content by hyperspectral and a mathematical model based on deep learning through the analysis and testing of the taken core.

[0015] Advantages of the present invention: By the different resistances received by the drill bit when drilling different formations, the transmission position between the frustum wheel and the friction wheel is changed. At the same time, the compression amount of the first spring between the mounting frame and the sliding shell is used to provide different pressures for the drill bit, so that the pressure and rotation speed of the drill bit are higher when drilling formations with high hardness, thus ensuring the drilling speed of the device.

[0016] According to the different resistances received by the drill bit in the vertical direction and the rotation direction, adjust the position of the adjusting plate, thereby changing the communication area of the communication shell, and then providing enough water for the drill bit to maintain the stability of its temperature and avoid the drill bit from getting too hot.

[0017] When the drill pipe is taken out of the drill hole, the drill pipe is cooled by cryogenic liquid, so that the oil sand ore in the drill pipe maintains a solidified state, which is convenient for taking out the core later and ensuring the accuracy of the sample information.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] A sampling device for geological exploration, as Figures 1 - 3 and Figure 5 shown, includes: a driving device 1, the driving device 1 is provided with a control terminal and a mounting frame 2; a sliding housing 3, slidably connected to the mounting frame 2, a first spring is arranged between the sliding housing 3 and the mounting frame 2, and the mounting frame 2 is rotatably connected with a rotating ring 4; a transfer member 5, slidably connected to the rotating ring 4, the transfer member 5 is rotatably connected with the sliding housing 3, and the transfer member 5 is provided with a connecting member 6; a drill pipe 7, threadedly connected to the connecting member 6, and the drill pipe 7 is threadedly connected with a drill bit 8; a motor 9, fixedly connected to the mounting frame 2, the output shaft of the motor 9 is fixedly connected with a frustum wheel 10, the transfer member 5 is fixedly connected with a friction wheel 11, and the friction wheel 11 and the frustum wheel 10 are frictionally driven. The friction coefficient of the side of the friction wheel 11 in the vertical direction is less than the friction coefficient of its circumferential direction.

[0022] In the above solution, it aims to achieve automatic adjustment of the rotation speed and pressure during the drilling of the drill bit 8, so that the drilling speed of the device is within a stable range. The driving device 1 is an existing device, which is used to adjust the drilling angle and the position of the mounting frame 2, and provide pressure for the drill bit 8 during drilling. The thrust of the mounting frame 2 is transmitted to the sliding shell 3 through the first spring. When vibrations occur during the drilling of the drill bit 8, the vibrations can be absorbed by the first spring, reducing the vibrations transmitted to the mounting frame 2, thereby reducing the vibrations of the driving device 1 and protecting the electronic components. Seals are provided between the sliding shell 3 and the transfer member 5, and between the transfer member 5 and the connecting member 6. Both the transfer member 5 and the connecting member 6 are hollow members for water to pass through. The generatrix of the frustum wheel 10 on the side close to the friction wheel 11 is in a vertical state, which is used to ensure that the friction wheel 11 always fits with the frustum wheel 10 when moving up and down. The friction wheel 11 and the frustum wheel 10 have less friction in the vertical direction, making it easier for the friction wheel 11 to move in the vertical direction.

[0023] Further, as Figure 4 shown, it further includes: a communication shell 12, fixedly connected to the mounting frame 2. The communication shell 12 is in communication with the sliding shell 3. The sliding shell 3 is used to supply water to the transfer member 5, thereby cooling the drill pipe 7 and the drill bit 8. The communication shell 12 is connected to a water supply device; an adjustment plate 13, slidably connected to the communication shell 12, and the adjustment plate 13 is used to adjust the communication area of the communication shell 12.

[0024] Further, as Figure 2 and Figure 4 shown, it further includes: a first shell 14, fixedly connected to the mounting frame 2; a first sliding member 15, slidably connected to the first shell 14, and the first sliding member 15 passes through the first shell 14 and is fixedly connected to the adjustment plate 13.

[0025] Further, as Figure 2 and Figure 3 shown, it further includes: a second shell 16, fixedly connected to the mounting frame 2. The second shell 16 is in communication with the first shell 14; a second sliding member 17, slidably connected to the second shell 16, and the second sliding member 17 is fixedly connected to the sliding shell 3.

[0026] In the above solution, it aims to supply water to the drill bit 8 during drilling and adjust the water supply amount according to the pressure during the drilling of the drill bit 8, so that the drill bit 8 can maintain a stable temperature when working under different pressures. The water supply device is an existing device, which is used to provide water flow to cool the drill bit 8. The communication shell 12 and the sliding shell 3 are connected by a hose. Seals are provided between the first sliding member 15 and the first shell 14, and between the second sliding member 17 and the second shell 16. The first shell 14 and the second shell 16 are connected by a hose, and both of them and the hose therebetween are filled with a liquid for transmission, such as hydraulic oil.

[0027] Workflow: When using this device to detect the distribution of oil sand ore, first move this device to the working location, then start the driving device 1 to drive the mounting frame 2 to move upward. The mounting frame 2 drives the intermediate member 5 to move upward through the rotating ring 4. The intermediate member 5 drives the connecting member 6 to move. When it has moved a sufficient distance to install the drill pipe 7, the mounting frame 2 stops moving. Then connect the drill pipe 7 to the connecting member 6 by threads, and then connect the drill bit 8 to the drill pipe 7. After the connection is completed, start the motor 9. The motor 9 drives the frustum wheel 10 to rotate. The frustum wheel 10 drives the friction wheel 11 to rotate through friction. The friction wheel 11 drives the intermediate member 5 to rotate. The intermediate member 5 drives the drill pipe 7 to rotate through the connecting member 6. The drill pipe 7 drives the drill bit 8 to rotate. Then start the water supply device to make water enter the communication shell 12, then enter the sliding shell 3 through the hose, and then flow out from the drill bit 8 through the intermediate member 5, the connecting member 6, and the drill pipe 7, so as to cool the drill pipe 7 and the drill bit 8 during drilling. After that, the driving device 1 drives the mounting frame 2 to move downward, and the mounting frame 2 drives the drill bit 8 to move downward, so that the drill bit 8 drills into the ground for sampling.

[0028] When the drill bit 8 contacts the ground, the drill bit 8 is subject to an upward resistance. At this time, the mounting bracket 2 continues to move, compressing the first spring between it and the sliding housing 3. At this time, the mounting bracket 2 drives the motor 9 to move downward relative to the friction wheel 11, and the motor 9 drives the frustum wheel 10 to move, thereby changing the transmission position between the frustum wheel 10 and the friction wheel 11 and increasing the rotation speed of the friction wheel 11. When the drilling speed of the drill bit 8 matches the pressure and rotation speed it receives, the frustum wheel 10 and the friction wheel 11 stop moving relative to each other, so that the device drills stably. When encountering a harder soil layer during drilling, the frustum wheel 10 and the friction wheel 11 will continue to move relative to each other, so as to drill the harder soil layer at a faster rotation speed and greater pressure to ensure the drilling speed. At the same time, the mounting bracket 2 drives the second housing 16 to move downward relative to the second sliding member 17, pressing the liquid in the second housing 16 into the first housing 14. The liquid in the first housing 14 increases, pushing the first sliding member 15 to move upward, and the first sliding member 15 drives the adjusting plate 13 to move upward. When the frustum wheel 10 and the friction wheel 11 stop moving relative to each other, the adjusting plate 13 also stops moving, thereby increasing the communication area of the communication housing 12, and further increasing the water inflow to ensure the cooling efficiency of the drill pipe 7 and the drill bit 8, and preventing the drill pipe 7 and the drill bit 8 from overheating due to the increase in rotation speed and pressure. When the sampling is completed, turn off the motor 9 and the water supply device, and make the driving device 1 drive the mounting bracket 2 to move upward. The mounting bracket 2 drives the drill pipe 7 and the drill bit 8 to move out of the drill hole. At this time, the pressure on the lower side of the drill bit 8 disappears, and the sliding housing 3 moves downward under the action of the first spring. The sliding housing 3 pushes the intermediate member 5 to move downward, and the intermediate member 5 drives the friction wheel 11 to move, so that the friction wheel 11 is reset. At the same time, the sliding housing 3 drives the second sliding member 17 to move, so that the second sliding member 17 and the second housing 16 return to their initial relative positions, and drives the adjusting plate 13 to reset. Then separate the connecting member 6, the drill pipe 7 and the drill bit 8 respectively, and take out the core in the drill pipe 7.

[0029] Further, as Figures 2 - 4 shown, it further includes: a first rotating shaft 18, rotatably connected to the intermediate member 5, the intermediate member 5 is rotatably connected to the connecting member 6, and the first rotating shaft 18 is fixedly connected with a third housing 19; a second rotating shaft 20, rotatably connected to the connecting member 6, the second rotating shaft 20 is fixedly connected with a third sliding member 21, the third sliding member 21 is slidably connected to the third housing 19, and a second spring is provided between the two; an annular housing 22, slidably connected to the mounting bracket 2, the annular housing 22 is rotatably connected to the intermediate member 5, the third housing 19 is provided with a pipeline, and the pipeline passes through the intermediate member 5 and communicates with the annular housing 22, and the annular housing 22 communicates with the first housing 14.

[0030] In the above solution, it is aimed to adjust the water supply according to the rotational resistance suffered by the drill bit 8 during drilling, so that the drill bit 8 can maintain a stable temperature when working under different rotational resistances. The number of the first rotating shafts 18 can be set as required. In the figure, there are three first rotating shafts 18 evenly distributed circumferentially. Seals are provided between the third housing 19 and the third sliding member 21, and between the annular housing 22 and the transfer member 5. Moreover, liquids for transmission are filled in the third housing 19 and between the annular housing 22 and the transfer member 5. The transfer member 5 and the connecting member 6 are driven by the second spring between the third sliding member 21 and the third housing 19. Thus, when vibrations occur during the drilling process of the drill bit 8, the vibrations can be absorbed by the second spring, reducing the vibrations transmitted to the transfer member 5. The annular housing 22 and the first housing 14 are communicated through a hose.

[0031] Workflow: When the device drills, the transfer member 5 drives the first rotating shaft 18 to rotate. The first rotating shaft 18 drives the third housing 19 to rotate. The third housing 19 slides relative to the third sliding member 21 and compresses the second spring between the two. At the same time, the liquid in the third sliding member 21 is pressed into the first housing 14. The third housing 19 pushes the third sliding member 21 to rotate through the second spring. The third sliding member 21 pushes the second rotating shaft 20 to rotate. The second rotating shaft 20 pushes the connecting member 6 to rotate. Thus, the rotation of the frustum wheel 10 is transmitted to the connecting member 6 to drive the drill bit 8 to rotate for drilling. When the rotational resistance suffered by the drill bit 8 is equal to the elastic force of the second spring between the third housing 19 and the third sliding member 21, the third housing 19 and the third sliding member 21 stop moving relative to each other. When the drill bit 8 drills to the oil sand ore, due to the asphalt contained in the oil sand ore, the oil sand ore is viscous, and the resistance suffered by the drill bit 8 during rotation increases. At this time, the third housing 19 further compresses the adjacent second spring, thereby pressing more liquid in it into the first housing 14, causing the first sliding member 15 to continue to drive the adjusting plate 13 to move upward, and further increasing the amount of water flowing out at the drill bit 8 to cool the oil sand ore, making the asphalt in a relatively hard but low-viscosity state, thereby reducing the probability of the oil sand ore adhering to the drill pipe 7 and the drill bit 8. At the same time, it prevents the asphalt from flowing more easily due to too high a temperature and flowing from the gap between the drill pipe 7 and the core to other positions, affecting the judgment of the distribution of the oil sand ore.

[0032] Further, as Figure 1 and Figure 5 shown, it further includes: a storage shell 23, fixedly connected to the driving device 1. The storage shell 23 is provided with an inlet and a spray port.

[0033] Further, as Figure 5 shown, it further includes: a plugging ring 24, slidably connected to the storage shell 23. The plugging ring 24 is used to plug the spray port of the storage shell 23. The plugging ring 24 is slidably connected to the drill pipe 7. The damping in the vertical direction between the plugging ring 24 and the drill pipe 7 is greater than the damping in the circumferential direction.

[0034] In the above solution, it is aimed to cool the drill pipe 7 to reduce the probability of asphalt adhering to the inner wall of the drill pipe 7, making it easier to take out the core from the drill pipe 7. A plug is provided at the inlet of the storage shell 23. Before the drill pipe 7 is taken out of the borehole, a cryogenic liquid, such as liquid nitrogen, is added into the storage shell 23. Taking the addition of liquid nitrogen as an example, after the addition, the inlet is blocked with the plug. Then, after the sealing ring 24 releases the blockage of the nozzle of the storage shell 23, the air pressure generated by the vaporization of the liquid nitrogen is used to spray the liquid nitrogen out of the nozzle of the storage shell 23, so as to evenly spray the liquid nitrogen on the drill pipe 7 and evenly cool the drill pipe 7. Even if the vaporization of the liquid nitrogen is too fast and the air pressure in the storage shell 23 is too high, the plug can be pushed open, and thus the inlet of the storage shell 23 is used for pressure relief.

[0035] Working process: When the drill pipe 7 of this device moves downward, the drill pipe 7 maintains the position of the sealing ring 24 through friction, so that the sealing ring 24 blocks the nozzle on the storage shell 23. Before the drill pipe 7 moves upward, a cryogenic liquid is added through the inlet of the storage shell 23. During the process of the drill pipe 7 and the drill bit 8 being removed from the borehole after the sampling of this device is completed, the drill pipe 7 drives the sealing ring 24 to move upward through friction, so that the sealing ring 24 releases the blockage of the nozzle on the storage shell 23. Then, the cryogenic liquid in the storage shell 23 is sprayed from the nozzle onto the drill pipe 7 to cool the drill pipe 7, so that the oil sand ore in the drill pipe 7 maintains a solidified state, which is convenient for taking out the core later and ensures the accuracy of the sample information.

[0036] Please refer to Figures 1 - 5 , a usage method of a sampling device for geological exploration. Based on the above sampling device for geological exploration, it specifically includes the following steps: S1: First, start the driving device 1, adjust the position of the mounting frame 2, then install the drill pipe 7 and the drill bit 8 through threads. After the connection is completed, start the motor 9, and the motor 9 drives the drill bit 8 to rotate; S2: Then start the water supply device, so that water enters the communication shell 12, then enters the sliding shell 3 through the hose, and then flows out from the drill bit 8 through the transfer member 5, the connecting member 6, and the drill pipe 7. After that, the driving device 1 drives the drill bit 8 to move downward for sampling; S3: When the resistance received by the drill bit 8 increases, at this time, the mounting frame 2 drives the motor 9 to move downward relative to the friction wheel 11, changing the transmission position of the frustum wheel 10 and the friction wheel 11, and increasing the rotation speed of the friction wheel 11; S4: At the same time, the mounting frame 2 drives the second shell 16 to move downward relative to the second sliding member 17, driving the adjusting plate 13 to move upward, thereby increasing the communication area of the communication shell 12, and further increasing the water inflow; S5: When the drill bit 8 drills to the oil sand ore, the resistance received by the rotating drill bit 8 increases, driving the adjusting plate 13 to move upward, and further increasing the amount of water flowing out from the drill bit 8 to cool the oil sand ore; S6: Before the sampling is completed, cryogenic liquid is added through the inlet of the storage shell 23. After the sampling is completed, the drill pipe 7 drives the plugging ring 24 to move upward by friction, so that the plugging of the nozzle on the storage shell 23 by the plugging ring 24 is released. Then, the cryogenic liquid in the storage shell 23 sprays from the nozzle towards the drill pipe 7 to cool the drill pipe 7. S7: When the sampling is completed, turn off the motor 9 and the water supply device, and make the driving device 1 drive the mounting frame 2 to move upward. The mounting frame 2 drives the drill pipe 7 and the drill bit 8 to move out of the drill hole. Then, separate the connector 6, the drill pipe 7 and the drill bit 8 respectively, take out the core in the drill pipe 7, and then establish a physical model for monitoring the oil content by hyperspectral and a mathematical model based on deep learning through the analysis and testing of the taken core.

[0037] In summary, the invention includes but is not limited to the above embodiments. Any equivalent replacement or partial improvement made under the spirit and principle of the present invention will be regarded as being within the protection scope of the present invention.

After the connection is completed, start the motor (9), and the motor (9) drives the drill bit (8) to rotate; S2: Then start the water supply device to make water enter the communication shell (12), then enter the sliding shell (3) through the hose, and then flow out from the drill bit (8) through the transfer member (5), the connecting member (6), and the drill pipe (7). After that, the driving device (1) drives the drill bit (8) to move downward for sampling; S3: When the resistance received by the drill bit (8) increases, at this time, the mounting frame (2) drives the motor (9) to move downward relative to the friction wheel (11), changes the transmission position of the frustum wheel (10) and the friction wheel (11), and increases the rotation speed of the friction wheel (11); S4: At the same time, the mounting frame (2) drives the second shell (16) to move downward relative to the second sliding member (17), driving the adjusting plate (13) to move upward, thereby increasing the communication area of the communication shell (12), and further increasing the water inflow; S5: When the drill bit (8) drills to the oil sand ore, the resistance received by the rotating drill bit (8) increases, driving the adjusting plate (13) to move upward, and further increasing the amount of water flowing out of the drill bit (8) to cool the oil sand ore; S6: Before the sampling is completed, add low-temperature liquid through the inlet of the storage shell (23). After the sampling is completed, the drill pipe (7) drives the plugging ring (24) to move upward by friction, so that the plugging ring (24) releases the plug of the nozzle on the storage shell (23), and then the low-temperature liquid in the storage shell (23) sprays from the nozzle to the drill pipe (7) to cool the drill pipe (7); S7: When the sampling is completed, turn off the motor (9) and the water supply device, and make the driving device (1) drive the mounting frame (2) to move upward. The mounting frame (2) drives the drill pipe (7) and the drill bit (8) to move out of the drill hole, then separate the connecting member (6), the drill pipe (7) and the drill bit (8) respectively, take out the core in the drill pipe (7), and then establish a physical model for monitoring the oil content by hyperspectral and a mathematical model based on deep learning through the analysis and testing of the taken core.
