Description

Technical Field

[0001] The present invention relates to the technical field of oil production engineering instruments, in particular to a soil layer surveying device for engineering surveying and a method thereof. Background Art

[0002] Soil layer drilling survey machines conduct geological surveys deep underground in the measurement of low-carbon oil and gas extraction projects, helping engineers understand the types, structures and distribution of underground rocks and determine the location and reserves of oil and gas reservoirs. This process starts from the ground, where a suitable exploration drilling point needs to be determined. The drilling rig then drills into the ground layer by layer. During the drilling process, the drill rig continuously rotates the drill bit, passing through different soil and rock layers until it reaches the target depth. Through detailed underground surveys, engineers can plan the safest and most economical drilling path, reduce unnecessary drilling times and energy consumption, in line with the goal of low-carbon development, and reduce waste and impact on the surrounding environment in the subsequent oil and gas extraction process. After the core drilling is completed, The coring operation must strictly follow the standard process. First, confirm the equipment status and prepare auxiliary tools. Then, lift the drill pipe in sections and use knocking vibration to loosen the core to avoid damage to the sample caused by forced extraction. After the core tube is removed, the core must be slowly pushed out with a core pusher. If it is stuck, rotation or tapping should be used to assist in removing it. The extracted cores must be arranged and cleaned in layer sequence, and the color, cracks and other characteristics must be recorded. They can be stored in segmented PVC pipes or customized core boxes, with buffer materials filled between layers, and depth numbered and packaged for protection. Special layers need to be handled separately. Finally, the core recovery rate is checked, the equipment is maintained, and the borehole is safely disposed of. The entire process emphasizes operational stability and sample integrity to ensure the accuracy of geological data and the reliability of subsequent engineering decisions.

[0003] However, during the coring operation, workers are still required to continuously strike the drill pipe using rotation, rubber hammers, etc., and make the drill pipe tilted or upright to release the core sample before they can collect and arrange the cores. In deep hole exploration operations in oil and gas formations, the total length of the drill pipe can reach tens of meters, and the length of the drill pipe sections is two to three meters. When striking the drill pipe with a rubber hammer, the position and force of the strike must be judged based on experience. If the first strike fails to loosen the core, multiple attempts at different points must be made, or even the striking tool may be replaced (such as using a metal hammer). In clay layers or tightly cemented rock formations, the process may last for tens of minutes, far exceeding the theoretical operation time. In addition, the core removal requires close cooperation between the drilling rig operator and the on-site workers: the former controls the drill pipe posture, and the latter performs the striking action. If communication is poor or there is an operational error (such as striking before the drill pipe is completely fixed), the process may need to be readjusted, further slowing down the progress of core extraction. Summary of the Invention

[0004] The purpose of the present invention is to provide a soil layer surveying device and method for engineering surveying, wherein the upper end of the drill rod to be cored is fixed by a free-style pick-up rod assembly, and the double-side belt lifting assembly drives the free-style pick-up rod assembly to rise until the drill rod is in an upright state, and a stepping motor is used to drive the upper belt conveyor structure and the follower-type double-position push-pull slide rod assembly to work. The follower-type double-position push-pull slide rod assembly forces the gear rack type impact rod assembly to continuously knock the drill rod in the upright state. The rock core detached during the knocking process falls on the upper belt conveyor structure and is sent out for collection, arrangement, and numbering operations by the staff, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a soil layer surveying device for engineering surveying, comprising:

[0006] A hollow bottom frame, a well frame is fixed to one side of the top of the hollow bottom frame, and a free-style pick-up assembly for clamping the end of the drill rod is installed on one outer wall of the well frame. A double-side belt lifting assembly for driving the free-style pick-up assembly to perform Z-axis lifting is installed inside the well frame, and a gear rack-type striker assembly is installed on the front and rear outer walls of the well frame;

[0007] An upper belt conveyor structure is installed on the top of the hollow bottom frame, and a lower belt conveyor structure is installed inside the hollow bottom frame below the upper belt conveyor structure. A reverse transmission structure is installed between the lower belt conveyor structure and the upper belt conveyor structure. A follower-type double-position push-pull slide bar assembly for receiving the rotational force from the reverse transmission structure is installed inside the hollow bottom frame. The follower-type double-position push-pull slide bar assembly is used to drive the two gear rack-type impact bar assemblies on the left and right outer walls of the well frame to work synchronously. A stepper motor for driving the upper belt conveyor structure is installed on the outer wall of the frame of the upper belt conveyor structure, and a control panel is installed on one side of the surface of the well frame. The output end of the control panel is electrically connected to the double-side belt lifting assembly, the free-style picking rod assembly, and the input end of the stepper motor respectively.

[0008] Preferably, the double-sided belt lifting assembly includes a lower transmission shaft and an upper transmission shaft rotatably installed at upper and lower positions inside the well frame, and a synchronous belt traction structure installed between the two ends of the surface of the lower transmission shaft and the upper transmission shaft. The double-sided belt lifting assembly also includes a back frame slidably installed on the inner wall of the well frame, the surface of the back frame is fixedly connected to the back side of the synchronous belt traction structure, the free-style picking rod assembly is installed on the back frame, and a rotating drive mechanism for driving the lower transmission shaft to rotate is installed at the bottom of the well frame.

[0009] Preferably, the rotation drive mechanism includes a reduction motor installed at the bottom of the well frame and a sprocket transmission structure installed at the end of the reduction motor drive shaft for driving the lower transmission shaft to rotate. Two symmetrical guide columns are installed on the inner wall of one side of the well frame, and the back frame and the guide columns are slidably matched. The input end of the reduction motor is electrically connected to the output end of the control panel.

[0010] Preferably, the free-style rod picking assembly includes two double right-angle wall side frames slidably mounted on one side of the well frame surface, a rotating shaft rotatably mounted on the outer wall of one side of the double right-angle wall side frame through a bearing seat, and a T-seat fixed between the opposite ends of the two rotating shafts, and a three-jaw pneumatic chuck is installed at one end of the T-seat surface.

[0011] Preferably, a cylinder is installed on the top of the T-seat, and the bottom end of the piston rod of the cylinder passes downward to the outside of the T-seat and is fixedly connected to the top of the three-jaw pneumatic chuck.

[0012] Preferably, the reverse transmission structure includes a transition shaft rotatably mounted on the outer wall of one side of the upper belt conveyor structure frame and a first-stage driving transmission structure mounted at one end of the transition shaft surface. The transition shaft and one of the belt rollers of the upper belt conveyor structure are power-connected through the first-stage driving transmission structure. A reversing gear disc is also mounted at one end of the transition shaft surface for power-engagement with one of the belt rollers of the lower belt conveyor structure.

[0013] Preferably, the follower-type double-position push-pull slide assembly includes a base frame fixed to the bottom of the hollow bottom frame, a Y-shaped angle plate slidably installed on the top of the base frame, and a short shaft rotatably installed on the outer wall of one side of the base frame. A secondary driving transmission structure is installed between one end of the short shaft and one of the belt rollers of the lower belt conveyor structure, and the other end of the short shaft is installed with a crank-connecting rod structure for driving the Y-shaped angle plate to perform reciprocating linear sliding.

[0014] Preferably, the rack and pinion type impact rod assembly includes an axle seat fixed on the outer wall of one side of the well frame, a vertical shaft rotatably installed on the top of the axle seat, and several impact rod curved arms fixed on the surface of the vertical shaft. A rack and pinion transmission structure for connecting the vertical shaft and the Y-shaped angle plate is installed on the outer wall of the axle seat away from the well frame.

[0015] Preferably, the rack and pinion transmission structure consists of a helical rack and a helical gear. The helical gear is fixed to the bottom end of the vertical shaft. The helical rack is slidably mounted on one side outer wall of the shaft seat and meshes with the helical gear. One end of the rack and pinion transmission structure is fixedly connected to one side outer wall of the Y-shaped angle plate.

[0016] The present invention also provides a soil layer surveying method for engineering surveying, such as the soil layer surveying device for engineering surveying described above, comprising the following steps:

[0017] S101: The staff starts the device through the control panel and sets the coring parameters, including the rotation speed of the follower double-position push-pull slide assembly and the expected lifting height of the free-style pick-up assembly by the double-side belt lifting assembly. The free-style pick-up assembly is used to wrap and tightly clamp the top of the drill pipe. After the top of the drill pipe is fixed by the free-style pick-up assembly, the double-side belt lifting assembly slowly lifts the free-style pick-up assembly until the drill pipe is gradually adjusted to an upright position.

[0018] S102: After the drill rod is in an upright state, the staff starts the stepper motor through the control panel to work. The stepper motor first drives the upper belt conveyor structure to work, and then the upper belt conveyor structure drives the lower belt conveyor structure to work through the reverse transmission structure. At this time, the conveying directions of the upper belt conveyor structure and the lower belt conveyor structure are opposite, and the lower belt conveyor structure drives the follower double-position push-pull slide bar assembly to move. The follower double-position push-pull slide bar assembly forces the gear rack type striker assembly to continuously knock the drill rod. The regular knocking action causes the rock core to gradually break away from the drill rod. The escaped rock core falls on the upper belt conveyor structure, and the upper belt conveyor structure gradually pushes the rock core along the conveying path to the next link;

[0019] S103: When the rock cores continue to fall on the belt surface of the upper belt conveyor structure and are conveyed away from the well frame, the staff places the PVC rock core box on the lower belt conveyor structure. The lower belt conveyor structure conveys the PVC rock core box toward the well frame so that the continuously conveyed rock cores fall evenly in the PVC rock core box until the PVC rock core box is conveyed out of the lower belt conveyor structure and is full of rock cores.

[0020] S104: After ensuring that all the cores in the drill rod have been successfully removed and collected, the staff lowers the free-style rod pickup assembly through the double-sided belt lifting assembly until the drill rod lies flat on the belt surface of the upper belt conveyor structure, then releases the clamping limit of the free-style rod pickup assembly and prepares for the next round of coring operations.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the soil layer surveying device for engineering surveying and the method thereof are provided with a vertical well frame, a double-side belt lifting assembly, a free-style pick-up rod assembly, a stepping motor, an upper belt conveyor structure, a follow-up double-position push-pull slide rod assembly and a gear rack type striker rod assembly and other structures that cooperate with each other. The upper end of the drill rod to be cored is fixed by the free-style pick-up rod assembly, and the double-side belt lifting assembly drives the free-style pick-up rod assembly to rise until the drill rod is in an upright state. The stepping motor is used to drive the upper belt conveyor structure and the follow-up double-position push-pull slide rod assembly to work. The follow-up double-position push-pull slide rod assembly forces the gear rack type striker rod assembly to continuously knock on the drill rod in the upright state. The rock core detached during the knocking process falls on the upper belt conveyor structure and is sent out.

[0022] The process of switching the drill rod from a horizontal state to an upright state is automatically completed by an electric mechanism through the cooperation of the double-side belt lifting assembly and the free-style rod picking assembly, eliminating the tedious steps of manually unlocking the chuck and manually adjusting the angle in traditional oil and gas soil exploration operations, so that the knocking operation can be started immediately, and the time for single posture adjustment is greatly shortened. The gear rack type striker assembly is driven by a stepper motor and a follower double-position push-pull slide assembly to achieve high-frequency, equal-amplitude regular knocking. Compared with the uneven force and rhythm fluctuation of manual knocking, the impact energy transmission of the mechanical striker is much better. The delivery is more uniform, effectively avoiding drill pipe deformation caused by local stress concentration. Especially in the dense rock formations of oil and gas exploration, the continuous and stable mechanical vibration can quickly destroy the adhesion between the core and the pipe wall. The upper belt conveyor structure is linked with the knocking action in real time. Once the core is detached, it is sent out immediately without waiting for manual collection. The operator only needs to number and package it at the terminal. This completely solves the process breakpoint of "processing-waiting-reprocessing" in the traditional coring operation of oil and gas soil exploration, making the drilling, coring and transportation a seamless closed-loop process.

[0023] Secondly, when the drill pipe is upright, the striking force of the mechanical striker is strictly transmitted along the axial direction of the drill pipe, avoiding the lateral force during manual tilting and striking. This vibration can maintain the natural bedding structure of the core to the maximum extent, especially for samples of fragile formations such as shale and coal seams. The protection effect is significantly improved. After the core falls off, it falls directly into the upper belt conveyor structure without manual grabbing or handling throughout the process, avoiding accidental falling or squeezing damage during traditional manual placement. In addition, the broken core with cracks is kept in a natural scattered state, retaining the real structural information for subsequent geological analysis. Through subsequent analysis of the core, it is possible to understand in detail the type, structure, porosity and oil and gas potential of the underground rock formation, helping the oil and gas mining engineering team to determine the location and scale of oil and gas reserves, and thus formulate a scientific and reasonable mining plan;

[0024] During the final operation, workers do not need to come into close contact with the vibrating drill pipe, completely avoiding the risk of mechanical injury in traditional hammering operations. The closed-loop motion trajectory design of the follower double-position push-pull slide bar assembly ensures that the mechanical components of the rack and pinion impact bar assembly operate within a preset safety range, eliminating the hidden dangers of tool splashing or equipment loss of control, and ensuring the safety of coring operations during oil and gas soil exploration.

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Embodiment 1, by Figures 1 to 5 The present invention includes a hollow bottom frame 1, a well frame 2 is fixed to one side of the top of the hollow bottom frame 1, and a free-style pick-up rod assembly 4 for clamping the end of the drill rod is installed on one side of the outer wall of the well frame 2. A double-side belt lifting assembly 3 for driving the free-style pick-up rod assembly 4 to perform Z-axis lifting is installed inside the well frame 2, and a gear rack type striker assembly 10 is installed on the front and rear outer walls of the well frame 2.

[0040] An upper belt conveyor structure 5 is installed on the top of the hollow bottom frame 1. A lower belt conveyor structure 6 is installed inside the hollow bottom frame 1 below the upper belt conveyor structure 5. A reverse transmission structure 8 is installed between the lower belt conveyor structure 6 and the upper belt conveyor structure 5. A follower-type double-position push-pull slide bar assembly 9 for receiving the rotational force from the reverse transmission structure 8 is installed inside the hollow bottom frame 1. The follower-type double-position push-pull slide bar assembly 9 is used to drive the two gear rack-type impact bar assemblies 10 on the left and right outer walls of the well frame 2 to work synchronously. A stepper motor 7 for driving the upper belt conveyor structure 5 is installed on the outer wall of the frame of the upper belt conveyor structure 5. A control panel 11 is installed on one side of the surface of the well frame 2. The output end of the control panel 11 is electrically connected to the input end of the double-sided belt lifting assembly 3, the free-style picking rod assembly 4, and the stepper motor 7 respectively.

[0041] A soil layer surveying method for engineering surveying in this embodiment, such as the above-mentioned soil layer surveying device for engineering surveying, includes the following steps:

[0042] S101: The staff starts the device through the control panel 11 and sets the coring parameters, including the rotation speed of the follower double-position push-pull slide assembly 9 and the expected lifting height of the free-style pick-up assembly 4 by the double-side belt lifting assembly 3. The free-style pick-up assembly 4 is used to wrap and tightly clamp the top of the drill pipe. After the top of the drill pipe is fixed by the free-style pick-up assembly 4, the double-side belt lifting assembly 3 slowly lifts the free-style pick-up assembly 4 until the drill pipe is gradually adjusted to an upright state.

[0043] S102: After the drill rod is in an upright state, the staff turns on the stepper motor 7 through the control panel 11 to work, and the stepper motor 7 first drives the upper belt conveyor structure 5 to work, and then the upper belt conveyor structure 5 drives the lower belt conveyor structure 6 to work through the reverse transmission structure 8. At this time, the conveying directions of the upper belt conveyor structure 5 and the lower belt conveyor structure 6 are opposite, and the lower belt conveyor structure 6 drives the follower double-position push-pull slide bar assembly 9 to move, and the follower double-position push-pull slide bar assembly 9 forces the gear rack type striker assembly 10 to continuously knock on the drill rod, and the regular knocking action is used to gradually separate the rock core from the drill rod, and the escaped rock core falls on the upper belt conveyor structure 5, and the upper belt conveyor structure 5 gradually pushes the rock core to the next link along the conveying path;

[0044] S103: As the cores continue to fall onto the belt surface of the upper belt conveyor structure 5 and are conveyed away from the well frame 2, the worker places the PVC core box on the lower belt conveyor structure 6. The lower belt conveyor structure 6 conveys the PVC core box toward the well frame 2, so that the continuously conveyed cores fall evenly into the PVC core box until the PVC core box is conveyed out of the lower belt conveyor structure 6 and is full of cores.

[0045] S104: After ensuring that all the cores in the drill rod have been successfully removed and collected, the staff lowers the free-style rod picking assembly 4 through the double-side belt lifting assembly 3 until the drill rod lies flat on the belt surface of the upper belt conveyor structure 5, and then releases the clamping limit of the free-style rod picking assembly 4 and prepares for the next round of coring operation.

[0046] Example 2, based on Example 1, Figure 6 、 Figure 7 and Figure 8 It is given that the double-side belt lifting assembly 3 includes a lower transmission shaft 302, an upper transmission shaft 303, and a synchronous belt traction structure 304 installed between the ends of the surfaces of the lower transmission shaft 302 and the upper transmission shaft 303, which are rotatably installed at the upper and lower positions inside the well frame 2. The double-side belt lifting assembly 3 also includes a back frame 305 slidably installed on the inner wall of the well frame 2, and the surface of the back frame 305 is fixedly connected to the back of the belt of the synchronous belt traction structure 304. The free-style picking rod assembly 4 is installed on the back frame 305. A rotary drive mechanism for driving the lower transmission shaft 302 to rotate is installed at the bottom of the well frame 2;

[0047] The rotary drive mechanism includes a reduction motor 301 installed at the bottom of the well frame 2 and a sprocket transmission structure 306 installed at the end of the drive shaft of the reduction motor 301 for driving the lower transmission shaft 302 to rotate. Two symmetrical guide posts 307 are installed on the inner wall of one side of the well frame 2. The back frame 305 and the guide posts 307 are slidably matched. The input end of the reduction motor 301 is electrically connected to the output end of the control panel 11. The cooperation between the reduction motor 301 and the sprocket transmission structure 306 can adjust the lifting speed and force according to actual needs to meet the requirements of different core extraction;

[0048] When the free-style rod picking assembly 4 is located at the bottom of the well frame 2 and actively clamps the end of the drill pipe, the staff starts the reduction motor 301 through the control panel 11 to work, and the reduction motor 301 drives the lower transmission shaft 302 to rotate through the sprocket transmission structure 306, and then the two synchronous belt traction structures 304 between the lower transmission shaft 302 and the upper transmission shaft 303 drive the back frame 305 and the free-style rod picking assembly 4 to move upward in the Z-axis direction, so that the drill pipe gradually becomes upright. The double-sided belt lifting assembly 3 ensures that the two sides of the well frame 2 are evenly stressed during the vertical lifting of the drill pipe, avoids deformation of the frame caused by unilateral traction, and ensures the continuity and reliability of the core removal operation during the exploration of oil and gas soil layers;

[0049] The free-style pick-up rod assembly 4 includes two double right-angle wall side frames 401 slidably mounted on one side of the surface of the well frame 2, a rotating shaft 402 rotatably mounted on the outer wall of one side of the double right-angle wall side frame 401 through a bearing seat, and a T-shaped seat 403 fixed between the opposite ends of the two rotating shafts 402. A three-claw pneumatic chuck 405 is installed at one end of the surface of the T-shaped seat 403, and a cylinder 404 is installed at the top of the T-shaped seat 403. The bottom end of the piston rod of the cylinder 404 extends downward to the outside of the T-shaped seat 403 and is connected to the three-claw pneumatic chuck 405. The top of the movable chuck 405 is fixedly connected. When the back frame 305 slides vertically along the guide column 307, the back frame 305 drives the double right-angle wall side frame 401, T-shaped seat 403 and other components upward. During this process, the three-jaw pneumatic chuck 405 firmly clamps the upper end of the drill pipe. The three-jaw pneumatic chuck 405 can automatically adjust the contact area according to the outer diameter of the drill pipe to avoid slippage caused by insufficient clamping force, thereby reducing the possibility of accidental slippage of the drill pipe and ensuring safety at the oil and gas soil exploration operation site.

[0050] The T-seat 403 deflects around the rotating shaft 402, allowing the cylinder 404 and the three-jaw pneumatic chuck 405 to obtain the function of A-axis rotation, helping the drill rod to be transformed from a lying state to an inclined and upright state, and improving the flexibility of the three-jaw pneumatic chuck 405 in clamping the rod.

[0051] Example 3, based on Example 2, Figure 9 、 Figure 10 、 Figure 11 and Figure 12It is given that the reverse transmission structure 8 includes a transition shaft 801 rotatably mounted on the outer wall of one side of the frame of the upper belt conveyor structure 5 and a first-level driving transmission structure 802 installed on one end of the surface of the transition shaft 801. The transition shaft 801 and one of the belt rollers of the upper belt conveyor structure 5 are powered by the first-level driving transmission structure 802. One end of the surface of the transition shaft 801 is also equipped with a reversing gear plate 803 for power engagement with one of the belt rollers of the lower belt conveyor structure 6. The stepper motor 7 and the upper belt conveyor structure 5 directly drive the escaped rock core to gradually move away from the well frame 2. The belt conveyor structure is a stable and gentle transportation method that helps To prevent the core from being broken or damaged, during this process, the belt roller connected to the upper belt conveyor structure 5 and the drive shaft of the stepper motor 7 drives the transition shaft 801 to rotate through the first-level drive transmission structure 802. Then, the transition shaft 801 drives the lower belt conveyor structure 6 via the reversing gear plate 803, so that the conveying directions of the upper belt conveyor structure 5 and the lower belt conveyor structure 6 are opposite, so that the PVC core box on the lower belt conveyor structure 6 moves toward the direction of the upper belt conveyor structure 5 and gradually receives the dropped cores, so that engineers can later analyze the type, structure and distribution of the underground rocks in this part to determine the location and reserves of oil and gas reserves;

[0052] The follower-type double-position push-pull slide bar assembly 9 includes a base frame 901 fixed to the bottom of the hollow bottom frame 1, a Y-shaped angle plate 905 slidably installed on the top of the base frame 901, and a short shaft 902 rotatably installed on the outer wall of one side of the base frame 901. A secondary driving transmission structure 903 is installed between one end of the short shaft 902 and one of the belt rollers of the lower belt conveyor structure 6. The other end of the short shaft 902 is installed with a crank-connecting rod structure 904 for driving the Y-shaped angle plate 905 to perform reciprocating linear sliding. One of the belt rollers of the lower belt conveyor structure 6 drives the short shaft 902 to rotate through the secondary driving transmission structure 903, and then the rotational power of the short shaft 902 is converted into a reciprocating linear sliding action of the Y-shaped angle plate 905 through the crank-connecting rod structure 904, thereby utilizing the Y-shaped angle plate 905 to force the gear rack type striker assembly 10 to work;

[0053] The rack and pinion type striker assembly 10 includes a shaft seat 1001 fixed on the outer wall of one side of the well frame 2, a vertical shaft 1002 rotatably mounted on the top of the shaft seat 1001, and a plurality of striker crank arms 1004 fixed on the surface of the vertical shaft 1002. A rack and pinion transmission structure 1003 for connecting the vertical shaft 1002 and the Y-shaped angle plate 905 is installed on the outer wall of the shaft seat 1001 away from the well frame 2. The rack and pinion transmission structure 1003 consists of a helical rack and a helical gear. The helical gear is fixed to the bottom end of the vertical shaft 1002. The helical rack is slidably mounted on the outer wall of one side of the shaft seat 1001 and meshes with the helical gear. One end of the rack and pinion transmission structure 1003 is fixedly connected to the outer wall of one side of the Y-shaped angle plate 905.

[0054] During the reciprocating linear sliding action of the Y-shaped angle plate 905, the Y-shaped angle plate 905 drives the helical rack of the gear rack transmission structure 1003 to move, and utilizes the helical rack and helical gear to drive the vertical shaft 1002 to rotate. During this process, the vertical shaft 1002 rotates back and forth at a certain angle, and the rotation angle is proportional to the sliding distance of the Y-shaped angle plate 905, that is, the vertical shaft 1002 drives the impact rod crank arm 1004 to continuously impact the drill rod, causing the rock core in the drill rod to loosen and detach. Through the smooth loosening and detachment of the rock core, the repeated operation of the drill rod and the device is reduced, thereby shortening the coring cycle after drilling, thereby reducing energy consumption and the amount of operation of the staff.

[0055] Before the operation of the embodiment of the present application begins, the staff should check the entire device to ensure that all mechanical components, including the well frame 2, the double-side belt lifting assembly 3, the free-style pick-up rod assembly 4, the stepper motor 7, the upper belt conveyor structure 5, the lower belt conveyor structure 6, the follow-up double-position push-pull slide assembly 9, the gear rack type impact rod assembly 10 and the control panel 11 are in normal working condition, and confirm that the power connection is good; next, the staff starts the device through the control panel 11, sets the coring parameters, including the rotation speed of the follow-up double-position push-pull slide assembly 9 and the expected lifting height of the double-side belt lifting assembly 3 to the free-style pick-up rod assembly 4. During this process, the worker pushes the end of the drill rod containing the core into the free-style pick-up rod assembly 4, and uses the free The free-style rod picking assembly 4 wraps and tightly clamps the top of the drill rod to ensure that the drill rod is firmly fixed. After the top of the drill rod is fixed by the free-style rod picking assembly 4, the double-sided belt lifting assembly 3 begins to slowly lift the free-style rod picking assembly 4 until the drill rod is gradually adjusted to an upright state, creating an ideal angle for subsequent operations. During this process, the staff must ensure that the lifting process is smooth without abnormal vibration or deviation; after the drill rod is in an upright state, the staff turns on the stepper motor 7 through the control panel 11 to work, and the stepper motor 7 first drives the upper belt conveyor structure 5 to work, and then the upper belt conveyor structure 5 drives the lower belt conveyor structure 6 to work through the reverse transmission structure 8. At this time, the conveying of the upper belt conveyor structure 5 and the lower belt conveyor structure 6 is The direction is opposite, and the lower belt conveyor structure 6 drives the follow-up double-position push-pull slide bar assembly 9 to move, and the follow-up double-position push-pull slide bar assembly 9 forces the gear rack type striker assembly 10 to continuously knock the drill rod, and uses regular knocking action to gradually separate the rock core from the drill rod, ensuring that the rock core is pulled out under the action of controlled force, and the rock core that has escaped falls on the upper belt conveyor structure 5, and the upper belt conveyor structure 5 gradually pushes the rock core to the next link along the conveying path; during the knocking process, the gear rack type striker assembly 10 on both sides of the well frame 2 continuously moves synchronously, repeatedly knocks the upright part of the drill rod, causing the rock core to gradually loosen and break away from the drill rod, and the staff continues to observe the state of the drill rod to confirm that the rock core is smoothly removed; when the rock core continues to fall on the upper belt conveyor When the drill rod is on the belt surface of the structure 5 and is sent out and away from the well frame 2, the staff places the PVC core box on the lower belt conveyor structure 6, and the lower belt conveyor structure 6 sends the PVC core box in the direction of the well frame 2, so that the continuously sent cores fall evenly in the PVC core box until the PVC core box is sent out of the lower belt conveyor structure 6 and is full of cores, and then the cores in the PVC core box are arranged and numbered; after ensuring that all the cores in this drill rod have been successfully taken out and collected, the staff lowers the free-style pick-up rod assembly 4 through the double-sided belt lifting assembly 3 until the drill rod lies flat on the belt surface of the upper belt conveyor structure 5, and then releases the clamping limit of the free-style pick-up rod assembly 4 and prepares for the next round of coring operation;After the core is extracted, the staff will analyze the type, structure, porosity, and oil and gas potential of the underground rock formation to understand the specific conditions of the underground oil and gas reservoir, avoid over-exploitation and waste of resources, and develop a reasonable low-carbon extraction plan to extend the service life of the oil and gas field and reduce the generation of waste and pollutants.
