TECHNICAL FIELD

[0001] The present application relates to the field of drilling operation, in particular to a kind of drilling operation intelligent shift inspection device and method. BACKGROUND

[0002] One of the core activities in drilling operation is tripping, i.e., frequently pulling or lowering the drill string from or into the borehole, which is required when performing tasks such as replacing drill bits, replacing worn-out drilling tools and coring, at which time the drill string and other drilling tools are basically hovering above the borehole, and the safety slips need to clamp the huge drill string hovering in the borehole, so the safety slips serve as the last line of defense for tripping, and thus the daily maintenance and detection of the safety slips are particularly important.

[0003] The safety slips are composed of fixed arms and movable arms connected by heavy hinges, and a plurality of replaceable rectangular tooth plates are installed on the inner inclined surface of the steel frame. Whenever the drill string gripped by the safety slips falls, the teeth will fall a small section before the C-shaped steel frame, and the teeth of the entire circle will be more tightly locked due to the inward retraction of the inclined surface inside the C-shaped steel frame. A gap is left between the back of each tooth plate and the slip base, and a spring is installed in the gap to reduce the initial impact when the drill string falls. Therefore, the spring rebound needs to be detected during the shift handover of workers in each shift, i.e., the teeth are pressed one by one with fingers, and then the rebound is observed to check the rebound. However, the pressing force of manual pressing is difficult to control, and the rebound is judged by the experience of workers, which has low accuracy. Therefore, during work, the buffer may not be in place, which may damage the safety slips and even cause the drill string to fall, resulting in personnel casualties. SUMMARY

[0004] In order to overcome the shortcomings that the teeth are pressed one by one with fingers, and then the rebound is observed to check the rebound, and the pressing force of manual pressing is difficult to control, and the rebound is judged by the experience of workers, which has low accuracy, the present application provides a kind of drilling operation intelligent shift inspection device and method.

[0005] The technical solution of the present application is: a kind of drilling operation intelligent shift inspection device, including installation frame;Further including drive assembly;Drive assembly is installed on installation frame;Lifting platform is connected to the lower side of drive assembly;Four placing tables are installed on drive assembly;Detection cylinder for detecting safety slips is connected to the middle part of installation frame.

[0006] As a further preferred scheme, the four placing tables can be combined into different sizes of rings by the driving of the drive assembly.

[0007] As a further preferred, the driving assembly comprises a first driving member and a second driving member; the first driving member is mounted on the mounting frame; the first driving member is connected with the lifting platform; four second driving members are fixedly connected on the lifting platform; and the output ends of each second driving member are fixedly connected with the adjacent placing table.

[0008] As a further preferred, the detection cylinder is connected by a plurality of groups of cylindrical bodies with continuously changing diameters, each group consisting of a rounded platform body and a cylindrical body.

[0009] As a further preferred, the oil stain detection assembly further comprises a driving unit, a moving block and a scraper ring; each rounded platform body of the detection cylinder is provided with a group of driving units; each group of driving units is connected with a moving block; and the lower side of each moving block is fixedly connected with a scraper ring.

[0010] As a further preferred, the oil stain detection assembly further comprises a driving unit, a moving block and a scraper ring; each rounded platform body of the detection cylinder is provided with a group of driving units; each group of driving units is connected with a moving block; and the lower side of each moving block is fixedly connected with a scraper ring.

[0011] As a further preferred, the scraper ring is provided in a funnel shape, and the detection cylinder is provided with an oil collecting opening at the connection position with the scraper ring.

[0012] As a further preferred, the scraper ring is provided in a funnel shape, and the detection cylinder is provided with an oil collecting opening at the connection position with the scraper ring.

[0013] As a further preferred, the scraper ring is provided in a funnel shape, and the detection cylinder is provided with an oil collecting opening at the connection position with the scraper ring.

[0014] A method for using a drilling construction intelligent shift inspection device, comprising the following working steps: S1: tooth plate detection: place the safety slips on the placing table, and move the detection cylinder downward, so that the rounded platform body extrudes the tooth plate teeth on the safety slips to realize rebound condition detection; S2: clamping detection: the third driving member simultaneously and quickly pushes the detection cylinder to move downward to simulate the rapid falling condition of the drill string and other drilling tools when falling; S3: Replenish lubricating oil: Introduce lubricating oil into the oil supply pipe corresponding to the location of the safety catch. The lubricating oil will flow out from the oil outlet and flow to the spring at the toothed plate, thereby completing the maintenance operation of the spring at the toothed plate. S4: Oil stain detection: The scraper ring evenly spreads lubricating oil onto the surface of the cylinder to simulate the scenario of oil stains on the drill string surface, thus achieving detection.

[0015] The present invention has the following advantages: The present invention compresses the teeth on the safety jaws by pressing the inverted truncated cone body, so that the springs inside the safety jaws are compressed synchronously, and then the rebound speed of each tooth is checked to know the state of each spring. The whole process is simple to operate and the results are accurate. It can press all the teeth with the same force at the same time, and compare the rebound of the teeth on the same plane to improve the detection accuracy and detection efficiency. The third drive component simultaneously and rapidly pushes the detection cylinder downwards to simulate the rapid fall of drilling tools such as drill strings. The safety slips are used to assess the cushioning effect of the detection cylinder and determine whether they can effectively provide emergency cushioning for the detection cylinder, thereby enabling convenient detection. By introducing lubricating oil into the oil supply pipe corresponding to the location of the safety catch, the lubricating oil flows out from the oil outlet and flows to the spring at the toothed plate, thereby completing the maintenance operation of the spring at the toothed plate and reducing the manual application of lubricating oil. By using a scraper ring to evenly apply lubricating oil to the surface of a cylinder, the scenario of oil contamination on the drill string surface is simulated, effectively improving the diversity and adaptability of the detection.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] Example 1: A smart shift handover inspection device for drilling operations, such as... Figures 1-5 As shown, it includes a mounting bracket 1; It also includes a drive assembly, a lifting platform 102, a placement platform 104, and a detection cylinder 105; the drive assembly is mounted on the mounting frame 1; the lifting platform 102 is connected to the lower side of the drive assembly; four placement platforms 104 are mounted on the drive assembly, and the four placement platforms 104 can be combined to form rings of different sizes to accommodate the detection of safety slips 2 of different sizes; the detection cylinder 105 is connected in the middle of the mounting frame 1, and the detection cylinder 105 is composed of multiple sets of columns with continuously changing diameters, each set consisting of an inverted frustum 10501 and a cylinder 10505, used to accommodate the detection of safety slips 2 of different sizes.

[0020] The drive assembly includes a first drive component 101 and a second drive component 103; the first drive component 101 is mounted on the mounting bracket 1, and the first drive component 101 consists of a motor and a lead screw; the first drive component 101 is connected to the lifting platform 102, and the lifting platform 102 is lifted and lowered through the first drive component 101; four second drive components 103 are fixedly connected to the lifting platform 102, and the second drive component 103 is an electric push rod; the output end of each second drive component 103 is fixedly connected to the adjacent placement platform 104.

[0021] One of the core activities in drilling operations is tripping in and out of the well, which involves frequently raising or lowering the drill string into and out of the well. Tripping in and out of the well is necessary when performing tasks such as changing drill bits, replacing worn drill tools, and coring. At this time, the drill string and other drill tools are basically suspended above the well, and safety slips 2 are needed to hold the huge drill string suspended in the well. In this case, safety slips 2 serve as the last line of defense for tripping in and out of the well. Therefore, the daily maintenance and inspection of safety slips 2 are particularly important.

[0022] The safety slip 2 consists of a fixed arm and a movable arm connected by a heavy-duty hinge. Multiple replaceable rectangular tooth plates are installed on the inclined surface inside the steel frame. Whenever the drill string engaged by the safety slip 2 falls, the tooth plates will fall slightly before the C-shaped steel frame. The entire ring of tooth plates, due to the inward convergence of the inclined surface inside the C-shaped steel frame, further locks the drill string tightly. A gap is left between the back of each tooth plate and the slip base, and a spring is installed in this gap to cushion the initial impact when the drill string falls. Therefore, the spring rebound needs to be checked at each shift change by pressing each tooth plate with a finger and then observing its rebound. However, the manual pressing pressure is difficult to control, and the rebound is judged based on the worker's experience, which has low accuracy. Therefore, during operation, insufficient cushioning may occur, damaging the safety slip 2 or even causing the drill string to fall, resulting in injury or death.

[0023] To solve the above problems, before starting work, each of the second drive components 103 moves the corresponding placement platform 104, adjusting the size of the ring formed by the four placement platforms 104 to match the size of the safety catch 2 after it is fastened. Then, the safety catch 2 is placed on the ring formed by the placement platforms 104. Then, the first drive component 101 drives the lifting platform 102 to rise. When the lifting platform 102 rises to the cylinder 10505 that matches the inner diameter of the safety catch 2, it continues to rise and contacts the corresponding inverted frustum 10501. As the safety catch 2 continues to rise, the inverted frustum 10501 gradually... The teeth on the safety jaws 2 are gradually compressed, and the springs inside the safety jaws 2 are compressed synchronously. Then, the first drive component 101 drives the lifting platform 102 to descend rapidly. Since the compression force is consistent, after the first drive component 101 descends rapidly, the state of each spring can be determined by comparing the rebound speed of each tooth (tooths with slower rebound need further inspection to check for other problems). The whole process is simple to operate and accurate. It can press all teeth with equal force at the same time and compare the rebound of teeth on the same plane to improve detection accuracy and efficiency.

[0024] Example 2, based on Example 1, such as Figure 6 and Figure 7As shown, it also includes a clamping force detection assembly, which includes a third drive component 201, a connecting ring 202, an electric oil outlet ring 203, an air inlet pipe 204, and an oil delivery pipe 205; two third drive components 201 are fixedly connected to the upper side of the mounting bracket 1, and the third drive component 201 is an electric push rod; the output ends of the two third drive components 201 are jointly fixedly connected to the connecting ring 202; the connecting ring 202 is fixedly connected to the upper side of the detection cylinder 105; each frustum 10501 of the detection cylinder 105 is equipped with an electric oil outlet. Ring 203; Each frustum 10501 of the detection cylinder 105 is provided with a plurality of air outlets 10502 arranged in an annular array; a plurality of air inlet pipes 204 are fixedly connected to the connecting ring 202, and the plurality of air inlet pipes 204 are respectively connected to the corresponding air outlets 10502; an oil supply pipe 205 is installed on the connecting ring 202; each frustum 10501 of the detection cylinder 105 is provided with a plurality of oil outlets 10503, and the oil outlets 10503 are respectively connected to the adjacent oil supply pipes 205.

[0025] Since the safety slip 2 serves as a safety buffer and fixation mechanism, it rarely functions properly under compliant operation by workers. Therefore, it is always difficult to guarantee that the safety slip 2 can effectively reduce the occurrence of accidents when dealing with emergencies. However, there is currently no equipment available to test the usage of the safety slip 2.

[0026] To address the aforementioned issues, the safety slips 2 are precisely clamped into the lower half of the cylinder 10505. Then, the two third drive components 201 simultaneously and rapidly push the detection cylinder 105 downwards to simulate the rapid descent of drill strings and other drilling tools. The cushioning effect of the safety slips 2 on the detection cylinder 105 is assessed to determine whether it can effectively provide emergency cushioning. This allows for convenient testing. If the safety slips 2 immediately clamp the detection cylinder 105 after the third drive component 201 is pushed, without significant displacement or damage, it indicates that the safety slips 2 is performing well and can continue to operate. If the detection cylinder 105 descends rapidly, or exhibits excessive displacement or slippage, it indicates that the clamping effect of the safety slips 2 is unqualified. The aforementioned testing operation effectively solves the problem of the inability to conveniently test the clamping performance of the safety slips 2 in existing technologies.

[0027] After the safety slip 2 passes inspection, rotate the electric oil outlet ring 203 to cover the oil outlet 10503. Then, high-speed airflow is introduced into the air inlet pipe 204 corresponding to the location of the safety slip 2. The high-speed airflow is ejected from the air outlet 10502 and cleans the spring at the tooth plate of the safety slip 2. After cleaning, rotate the electric oil outlet ring 203 back to its original position, keeping the oil outlet 10503 exposed, and introduce lubricating oil into the oil supply pipe 205 corresponding to the location of the safety slip 2. The lubricating oil flows out from the oil outlet 10503 and flows to the spring at the tooth plate, thus completing the maintenance operation of the spring at the tooth plate and reducing the manual application of lubricating oil. Example 3

[0028] Based on Example 2, such as Figure 8 As shown, it also includes an oil stain detection component, which includes a drive unit, a moving block 302, and a scraper ring 303. Each inverted frustum 10501 of the detection cylinder 105 is provided with a set of drive units, which consist of a motor and a lead screw. Each set of drive units is connected to a moving block 302. A scraper ring 303 is fixedly connected to the lower side of each moving block 302, and the inner ring surface of the scraper ring 303 is in contact with the outer surface of the adjacent cylinder 10505 for limiting and collecting lubricating oil.

[0029] The scraper ring 303 is made of rubber.

[0030] The scraper ring 303 divides the cylinder 10505 into upper and lower parts to enable detection in different environments.

[0031] The scraper ring 303 is funnel-shaped, and an oil collection port 10504 is provided at the connection between the detection cylinder 105 and the scraper ring 303 for collecting lubricating oil.

[0032] A detection method for an intelligent shift handover inspection device in drilling operations includes the following steps: S1: Tooth plate detection: Place the safety slip 2 on the placement table 104, move the detection cylinder 105 downward, and the inverted frustum 10501 squeezes the tooth plate on the safety slip 2 to detect the springback. S2: Clamping detection: The third drive component 201 simultaneously and rapidly pushes the detection cylinder 105 downward to simulate the situation of drill string and other drilling tools falling rapidly during the fall; S3: Replenish lubricating oil: Introduce lubricating oil into the oil supply pipe 205 corresponding to the location of the safety slip 2. The lubricating oil flows out from the oil outlet 10503 and flows to the spring at the toothed plate, thereby completing the maintenance operation of the spring at the toothed plate. S4: Oil stain detection: The scraper ring 303 evenly scrapes lubricating oil onto the surface of the cylinder 10505 to simulate the scenario of oil stains on the drill string surface, thus achieving detection.

[0033] The working environment in mines is complex and harsh. After drill strings and other drilling tools are lifted from the mine to the wellhead, their surfaces may be contaminated with mud or oil. This mud or oil can affect the normal operation of the safety slips 2. Therefore, in order to improve the accuracy of detection and the working condition of the safety slips 2 under different environments, it is necessary to simultaneously detect the working condition of the safety slips 2 when there is oil on the surface of the cylinder 10505. When it is necessary to detect the buffering effect of the safety slips 2 when there is oil on the surface of the cylinder 10505, the fourth driving component 301 drives the moving block 302 to move upward, and the moving block 302 then drives... The scraper ring 303 moves upward, and then uses the scraper ring 303 to evenly scrape the lubricating oil onto the surface of the cylinder 10505 (if the lubricating oil inside the scraper ring 303 is insufficient to form an oil film, the lubricating oil can continue to flow out through the oil outlet 10503), thereby simulating the scenario where there is oil on the drill string surface. At this time, the safety slip 2 is properly installed on the upper part of the cylinder 10505, and then the third drive component 201 drives the detection cylinder 105 to move downward. The above detection work is repeated to detect the performance of the safety slip 2 in this environment, which effectively improves the diversity and adaptability of the detection.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
