Description

Technical Field

[0001] The present invention relates to the technical field of oil extraction engineering equipment, and particularly to a soil layer survey device and method for engineering measurement. Background Art

[0002] In the engineering measurement of low-carbon oil and gas extraction, the soil layer drilling survey machine conducts geological exploration by drilling deep into the ground, helping engineers understand the types, structures, and distributions of underground rocks, judge the locations and reserves of oil and gas reservoirs. This process starts from the ground, where a suitable survey drilling point needs to be determined, and then the drill rig drills into the ground layer by layer. During the drilling process, the drill rig continuously rotates the drill bit, passing through different soil layers and rock layers until the target depth is reached. Through detailed underground exploration, engineers can plan the safest and most economical drilling path, reduce unnecessary drilling times and energy consumption, meet the goal of low-carbon development, and reduce waste and environmental impact during subsequent oil and gas extraction; after the core drilling is completed, the core extraction operation needs to strictly follow the standard process. First, confirm the equipment status and prepare auxiliary tools, then lift the drill pipe in sections and cooperate with knocking and vibration to loosen the core, avoiding damage to the sample caused by forced extraction; after the core barrel is disassembled, the core needs to be slowly pushed out with a core pusher. When it gets stuck, rotation or gentle knocking methods can be used to assist in removing it. The extracted cores need to be arranged and cleaned in sequence, and features such as color and fissures are recorded. They can be stored in segmented PVC pipes or customized core boxes, with buffer materials filled between layers, and depth numbers and encapsulation protection are carried out. Special strata need to be treated separately. Finally, check the core recovery rate, maintain the equipment, and safely dispose of the drilling hole. The whole process emphasizes operation stability and sample integrity to ensure the accuracy of geological data and the reliability of subsequent engineering decisions;

[0003] However, in the core extraction operation stage, it is still necessary for workers to continuously knock various parts of the drill pipe using methods such as rotation and rubber hammers, and keep the drill pipe in an inclined or upright state to make the core sample come out, and then the core collection and arrangement operations can be carried out. During the deep-hole survey operation of oil and gas soil layers, the total length of the drill pipe can reach dozens of meters, and the length of each section of the drill pipe is two to three meters. When using a rubber hammer to knock the drill pipe, it is necessary to judge the knocking position and force through experience. If the core is not loosened by the first knock, it is necessary to try different positions multiple times, or even replace the knocking tool (such as changing to a metal hammer). In clay layers or tightly cemented rock layers, this process may last for dozens of minutes, far exceeding the theoretical operation time. And knocking out the core requires close cooperation between the drill rig operator and the on-site workers: the former controls the posture of the drill pipe, and the latter performs the knocking action. If there is poor communication or operational errors (such as knocking starts when the drill pipe is not fully fixed), the process may need to be readjusted, further slowing down the core extraction progress. Summary of the Invention

[0004] The purpose of the present invention is to provide a soil exploration device and method for engineering survey. The upper end of the drill rod to be cored is fixed by a free-style rod-picking assembly, and the double-sided belt lifting assembly drives the free-style rod-picking assembly to rise until the drill rod is in an upright state. The stepping motor drives the upper belt conveying structure and the follow-up double-position push-pull sliding rod assembly to work. The follow-up double-position push-pull sliding rod assembly forces the gear-rack type impact rod assembly to continuously strike the drill rod in the upright state. During the striking process, the detached core falls on the upper belt conveying structure and is sent out for the staff to collect, arrange, and number, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A soil exploration device for engineering survey, comprising:

[0006] A hollow bottom frame, one side of the top of the hollow bottom frame is fixed with a well frame, and a free-style rod-picking assembly for clamping the end of the drill rod is installed on the outer wall of one side of the well frame.

A lower belt conveying structure is installed inside the hollow bottom frame below the upper belt conveying structure. A reverse transmission structure is installed between the lower belt conveying structure and the upper belt conveying structure.

[0009] Preferably, the rotation drive mechanism includes a reduction motor installed at the bottom of the well frame and a sprocket drive structure installed at the end of the drive shaft of the reduction motor for driving the lower transmission shaft to rotate. Two symmetric guiding columns are installed on one inner wall of the well frame, and the back frame is slidably engaged with the guiding columns. 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 installed on one side of the surface of the well frame, a rotating shaft rotatably installed on the outer wall of one side of the double right-angle wall side frame through a bearing seat, and a T-shaped seat fixed between the opposite ends of the two rotating shafts. A three-jaw pneumatic chuck is installed at one end of the surface of the T-shaped seat.

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

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

[0013] Preferably, the follow-up double-position push-pull sliding rod assembly includes a chassis fixed at the bottom of the hollow bottom frame, a Y-shaped gusset slidably installed at the top end of the chassis, and a short shaft rotatably installed on the outer wall of one side of the chassis. A second-stage driving transmission structure is installed between one end of the short shaft and one of the belt rollers of the lower belt conveyor structure.

[0014] Preferably, the gear-rack type impact rod assembly includes a shaft seat fixed on the outer wall of one side of the well frame, a vertical shaft rotatably installed at the top end of the shaft seat, and a plurality of impact rod crank arms fixed on the surface of the vertical shaft. A gear-rack transmission structure for connecting the vertical shaft and the Y-shaped gusset is installed on the outer wall of the shaft seat away from the well frame.

[0015] Preferably, the gear-rack transmission structure is composed of an inclined rack and an inclined gear. The inclined gear is fixed at the bottom end of the vertical shaft. The inclined rack is slidably installed on the outer wall of one side of the shaft seat and meshes with the inclined gear. One end of the gear-rack transmission structure is fixedly connected to the outer wall of one side of the Y-shaped gusset.

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

[0017] S101: The operator starts the device through the control panel and sets the coring parameters, including the rotation speed of the follow-up dual-position push-pull slide rod assembly and the expected lifting height of the double-sided belt lifting assembly for the free rod picking assembly. The free rod picking assembly wraps around and tightly clamps the top of the drill pipe. After the top of the drill pipe is fixed by the free rod picking assembly, the double-sided belt lifting assembly slowly lifts the free rod picking assembly until the drill pipe is gradually adjusted to an upright state;

[0018] S102: After the drill pipe is in an upright state, the operator turns on the stepper motor to work through the control panel. 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 follow-up dual-position push-pull slide rod assembly to act. The follow-up dual-position push-pull slide rod assembly forces the gear-rack type striker assembly to continuously strike the drill pipe, and the regular striking action causes the core to gradually break away from the drill pipe. The removed core falls on the upper belt conveyor structure, and the upper belt conveyor structure gradually pushes the core along the conveying path to the next link;

[0019] S103: When the core continuously falls on the belt surface of the upper belt conveyor structure and is sent out and away from the well frame, the operator places the PVC core box on the lower belt conveyor structure. The lower belt conveyor structure sends the PVC core box towards the well frame direction, so that the continuously sent core evenly falls into the PVC core box until the PVC core box is sent out of the lower belt conveyor structure and filled with core;

[0020] S104: After ensuring that all the cores in this drill pipe have been successfully removed and collected, the operator lowers the free rod picking assembly through the double-sided belt lifting assembly until the drill pipe lies flat on the belt surface of the upper belt conveyor structure. Then, the clamping restriction of the free rod picking assembly is released, and the next round of coring operation is prepared.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The soil exploration device and method for engineering measurement are provided with mutually cooperating structures such as a vertical well frame, a double-sided belt lifting assembly, a free rod picking assembly, a stepper motor, an upper belt conveyor structure, a follow-up dual-position push-pull slide rod assembly, and a gear-rack type striker assembly. The upper end of the drill pipe to be cored is fixed by the free rod picking assembly, and the double-sided belt lifting assembly drives the free rod picking assembly to rise until the drill pipe is in an upright state. The stepper motor drives the upper belt conveyor structure and the follow-up dual-position push-pull slide rod assembly to work. The follow-up dual-position push-pull slide rod assembly forces the gear-rack type striker assembly to continuously strike the drill pipe in an upright state. During the striking process, the separated core falls on the upper belt conveyor structure and is sent out;

[0022] Through the cooperation of the double-sideband lifting assembly and the free-style rod-lifting assembly, the process of switching the drill pipe from the horizontal state to the vertical state is automatically completed by the electric mechanism, eliminating the cumbersome steps of manually unlocking the chuck and manually adjusting the angle in traditional oil and gas soil exploration operations. This enables the percussion operation to be started immediately, significantly shortening the single-time attitude adjustment time. The rack and pinion type impact rod assembly, driven by a stepper motor and a follow-up double-position push-pull slide rod assembly, realizes high-frequency and equal-amplitude regular percussion. Compared with the uneven force and fluctuating rhythm of manual percussion, the impact energy transmission of the mechanical impact rod is more uniform, effectively avoiding the deformation of the drill pipe caused by local stress concentration. Especially in the relatively compact rock formations in oil and gas exploration soil layers, the continuous and stable mechanical vibration can quickly break the adhesion between the core and the pipe wall. The upper belt conveyor structure is linked in real time with the percussion action. Once the core is detached, it is sent out immediately without waiting for manual collection. The operator only needs to number and package at the terminal, completely solving the process breakpoint of "processing - waiting - reprocessing" in traditional core removal operations in oil and gas soil exploration, and enabling seamless connection of the closed-loop processes of drill pipe lifting, core removal, and conveying;

[0023] Secondly, in the state of the vertical drill pipe, the percussion force of the mechanical impact rod is strictly transmitted along the axial direction of the drill pipe, avoiding the lateral component force during manual inclined percussion. This kind of vibration can maximally maintain the natural bedding structure of the core, especially significantly improving the protection effect on fragile formation samples such as shale and coal seams. After the core falls off, it directly drops into the upper belt conveyor structure, without any manual grasping or handling throughout the process, avoiding accidental dropping or extrusion damage during traditional manual placement. Moreover, for fractured cores with cracks, their natural scattered state is maintained, retaining the true structural information for subsequent geological analysis. By analyzing the core subsequently, the type, structure, porosity, and oil and gas-bearing potential of the underground rock formations can be understood in detail, helping the oil and gas exploitation engineering team determine the location and scale of the oil and gas reserves, and thus formulating a scientific and reasonable exploitation plan;

[0024] Finally, during the operation process, the staff does not need to be in close contact with the vibrating drill pipe, completely avoiding the risk of mechanical injury in traditional percussion operations. Moreover, the closed-loop motion trajectory design of the follow-up double-position push-pull slide rod assembly ensures that the mechanical components of the rack and pinion type impact rod assembly work within the preset safe range, eliminating the hidden dangers of tool splashing or equipment out of control, and ensuring the safety of the core-taking operation during the oil and gas soil exploration process.

Detailed implementation manners

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1 is given by Figures 1 to 5 The present invention includes a hollow bottom frame 1. One side of the top end of the hollow bottom frame 1 is fixedly provided with a well frame 2. And a free type rod picking assembly 4 for clamping the end of a drill pipe is installed on the outer wall of one side of the well frame 2. A double-sided belt lifting assembly 3 for driving the free type rod picking assembly 4 to perform Z-axis lifting is installed inside the well frame 2. Gear rack type impact rod assemblies 10 are installed on the front and rear outer walls of the well frame 2.

[0040] An upper belt conveying structure 5 is installed on the top end of the hollow bottom frame 1. A lower belt conveying structure 6 is installed inside the hollow bottom frame 1 below the upper belt conveying structure 5. A reverse transmission structure 8 is installed between the lower belt conveying structure 6 and the upper belt conveying structure 5. A following type double-position push-pull sliding rod assembly 9 for receiving the rotating power from the reverse transmission structure 8 is installed inside the hollow bottom frame 1. The following type double-position push-pull sliding rod assembly 9 is used to drive the two gear rack type impact rod assemblies 10 on the left and right outer walls of the well frame 2 to work synchronously. A stepping motor 7 for driving the upper belt conveying structure 5 to work is installed on the outer wall of the frame of the upper belt conveying 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 ends of the double-sided belt lifting assembly 3, the free type rod picking assembly 4, and the stepping motor 7 respectively.

[0041] A soil layer survey method for engineering measurement in this embodiment, such as the above-mentioned soil layer survey device for engineering measurement, 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 following type double-position push-pull sliding rod assembly 9 and the expected lifting height of the double-sided belt lifting assembly 3 for the free type rod picking assembly 4. The free type rod picking assembly 4 is used to wrap and tightly clamp the top end of the drill pipe. After the top end of the drill pipe is fixed by the free type rod picking assembly 4, the double-sided belt lifting assembly 3 slowly lifts the free type rod picking assembly 4 until the drill pipe is gradually adjusted to an upright state.

[0043] S102: After the drill pipe is in an upright state, the operator turns on the stepper motor 7 through the control panel 11 to make it work. First, the stepper motor 7 drives the upper belt conveying structure 5 to work. Subsequently, the upper belt conveying structure 5 drives the lower belt conveying structure 6 to work through the reverse transmission structure 8. At this time, the conveying directions of the upper belt conveying structure 5 and the lower belt conveying structure 6 are opposite, and the lower belt conveying structure 6 drives the follow-up dual-position push-pull slide rod assembly 9 to act. The follow-up dual-position push-pull slide rod assembly 9 forces the gear-rack type impact rod assembly 10 to continuously strike the drill pipe, and the core is gradually separated from the drill pipe by the regular striking action. The separated core falls on the upper belt conveying structure 5, and the upper belt conveying structure 5 gradually pushes the core along the conveying path to the next link;

[0044] S103: When the core continuously falls on the belt surface of the upper belt conveying structure 5 and is sent out and away from the well frame 2, the operator places the PVC core box on the lower belt conveying structure 6. The lower belt conveying structure 6 sends the PVC core box in the direction of the well frame 2, so that the continuously sent core evenly falls into the PVC core box until the PVC core box is sent out of the lower belt conveying structure 6 and filled with core;

[0045] S104: After ensuring that all the core in this drill pipe has been successfully taken out and collected, the operator lowers the free rod picking assembly 4 through the double-sided belt lifting assembly 3 until the drill pipe lies flat on the belt surface of the upper belt conveying structure 5. Subsequently, the clamping restriction of the free rod picking assembly 4 is released, and the next round of core sampling operation is prepared.

[0046] Embodiment 2 is given on the basis of Embodiment 1 by Figure 6 、 Figure 7 and Figure 8 The double-sided belt lifting assembly 3 includes a lower transmission shaft 302 and an upper transmission shaft 303 rotatably installed at the upper and lower positions inside the well frame 2, and a synchronous belt traction structure 304 installed between the two ends of the surfaces of the lower transmission shaft 302 and the upper transmission shaft 303. The double-sided belt lifting assembly 3 further includes a back frame 305 slidably installed on the inner wall of the well frame 2. 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 rod picking assembly 4 is installed on the back frame 305, and a rotation driving 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 drive 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 guiding columns 307 are installed on one inner wall of the well frame 2, and the back frame 305 is in sliding fit with the guiding columns 307. The input end of the reduction motor 301 is electrically connected to the output end of the control panel 11. The coordinated operation of the reduction motor 301 and the sprocket drive structure 306 can adjust the lifting speed and force according to actual needs to meet the requirements for removing different cores;

[0048] When the free-style rod-picking assembly 4 is at the lowermost end of the well frame 2 and actively clamps the end of the drill pipe, the staff turns on the reduction motor 301 through the control panel 11 to work. The reduction motor 301 drives the lower transmission shaft 302 to rotate through the sprocket drive structure 306. Subsequently, 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 together, so that the drill pipe gradually becomes upright. The double-sided belt lifting assembly 3 ensures that both sides of the well frame 2 are evenly stressed during the vertical lifting of the drill pipe, avoiding the frame deformation caused by unilateral traction, and ensuring the continuity and reliability of the core extraction operation during the oil and gas soil exploration process;

[0049] The free-style rod-picking assembly 4 includes two double right-angle wall side frames 401 slidably installed on one side of the surface of the well frame 2, a rotating shaft 402 rotatably installed 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. One end of the surface of the T-shaped seat 403 is equipped with a three-jaw pneumatic chuck 405, 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 penetrates downward to the outside of the T-shaped seat 403 and is fixedly connected to the top of the three-jaw pneumatic chuck 405. When the back frame 305 slides along the vertical direction of the guiding column 307, the back frame 305 drives the double right-angle wall side frame 401, the T-shaped seat 403 and other components to move 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, avoiding slippage caused by insufficient clamping force, so as to reduce the possibility of accidental sliding of the drill pipe and ensure the safety of the oil and gas soil exploration operation site;

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

[0051] Embodiment 3, on the basis of Embodiment 2, by Figure 9 、 Figure 10 、 Figure 11 and Figure 12Given that, the reverse drive structure 8 includes a transition shaft 801 rotatably installed on the outer wall of one side of the frame of the upper belt conveyor structure 5, and a primary drive transmission structure 802 installed at one end of the surface of the transition shaft 801. One of the belt rollers of the transition shaft 801 and the upper belt conveyor structure 5 is power-connected through the primary drive transmission structure 802. A reversing gear disc 803 for power engagement with one of the belt rollers of the lower belt conveyor structure 6 is also installed at one end of the surface of the transition shaft 801. The stepping motor 7 and the upper belt conveyor structure 5 directly drive the ejected core to gradually move away from the well frame 2. The smooth and gentle handling method of the belt conveyor structure helps prevent the core from being broken or damaged. During this process, the belt roller connected to the drive shaft of the stepping motor 7 of the upper belt conveyor structure 5 drives the transition shaft 801 to rotate through the primary drive transmission structure 802. Subsequently, the transition shaft 801 drives the lower belt conveyor structure 6 to work by using the reversing gear disc 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 towards the upper belt conveyor structure 5 and gradually receives the falling core, so as to facilitate the engineer to subsequently judge the location and reserves of the oil and gas storage by analyzing the types, structures and distribution of the underground rocks in this part;

[0052] The follow-up type double-position push-pull slide rod assembly 9 includes a chassis 901 fixed to the bottom of the hollow bottom frame 1, a Y-shaped gusset 905 slidably installed at the top of the chassis 901, and a short shaft 902 rotatably installed on the outer wall of one side of the chassis 901. A secondary drive 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. A crank and connecting rod structure 904 for driving the Y-shaped gusset 905 to perform reciprocating linear sliding is installed at the other end of the short shaft 902. One of the belt rollers of the lower belt conveyor structure 6 drives the short shaft 902 to rotate through the secondary drive transmission structure 903. Subsequently, the rotational power of the short shaft 902 is converted into the reciprocating linear sliding action of the Y-shaped gusset 905 through the crank and connecting rod structure 904, so as to force the gear and rack type striker assembly 10 to work by using the Y-shaped gusset 905;

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

[0054] During the reciprocating linear sliding motion of the Y-shaped angle plate 905, the Y-shaped angle plate 905 drives the inclined rack of the gear-rack transmission structure 1003 to move. By using the inclined rack and the inclined gear, the vertical shaft 1002 is driven to rotate. During this process, the vertical shaft 1002 reciprocates and rotates forward and backward by a certain angle. This 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 1004 to continuously impact the drill pipe, promoting the loosening and detachment of the core in the drill pipe. Through the smooth progress of the core loosening and detachment, the repeated operation of the drill pipe and the device is reduced, thereby shortening the core-taking cycle after drilling, and thus reducing energy consumption and the operation volume of the staff.
