Description

Technical Field

[0001] The invention relates to the technical field of petroleum sampling, in particular to a petroleum distribution sampling device used in petroleum mining. Background Art

[0002] Oil extraction is a complex process involving exploration, drilling, development and production, aimed at extracting oil resources from underground reservoirs. With the advancement of technology, new extraction methods such as horizontal wells and hydraulic fracturing are widely used to improve recovery and efficiency.

[0003] After searching, the Chinese patent with the announcement number CN117213908B discloses a petroleum distribution sampling device for oil mining, including a motor, the motor is fixedly mounted on the bottom of the connecting plate, the power output shaft of the motor is fixedly mounted with a support rod, the outer wall of the support rod is fixedly mounted with a set of limit plates, and the outer side of the support rod is slidably mounted with a set of first bevel gears; the outer side wall of the sampling plate is provided with a slide groove, the inner side of the slide groove is slidably mounted with a slider, the outer side wall of the slider is rotatably mounted with a connecting rod, one end of the connecting rod is fixedly mounted with a drill bit, the other end of the connecting rod is fixedly mounted with a second bevel gear matching the first bevel gear, and the outer side wall of the slider is fixed with a support plate, so that the sampling device can be properly adjusted according to the thickness between different soil layers, avoiding that two adjacent storage chambers take out soil from the same soil layer, and at the same time, the method of drilling the soil with a drill bit can avoid the sampling device from encountering stones and being damaged, thereby improving the service life of the sampling device. However, the above scheme still has the following shortcomings in actual use:

[0004] The sampling operation of the above-mentioned sampling equipment relies on the coordinated work of the connecting rod and the drill bit. The drill bit is rotated to break the stratum and try to collect samples. However, although the drill bit can effectively break the soil, it is often difficult to smoothly guide the broken soil or rock debris out of the sampling hole in large quantities. At the same time, after each sampling, the staff must completely remove the entire sampling device from the oil well before taking out the sample for subsequent analysis. This operation method is not only time-consuming and labor-intensive, but also greatly reduces the continuity and efficiency of sampling.

[0005] Therefore, it is necessary to design a petroleum distribution sampling device for oil mining to solve the above problems. Summary of the invention

[0054] As a preferred technical solution of the present invention, mounting brackets are fixedly mounted on both ends of the mounting frame.

[0055] The present invention has the following beneficial effects:

[0056] 1. By setting up the installation frame, sampling plate and mounting frame, the sampling device can flexibly adjust the sampling position and direction through the use of the electric push rod and the sampling plate, so as to meet the sampling requirements of different depths and angles in the oil well, greatly improve the sampling efficiency and accuracy, and obtain more comprehensive oil distribution information;

[0057] 2. By setting the transmission component and the sampling component, the electric push rod 2 is started at the right time, and the inclined surface design is used to automatically drive the drill plate to gradually expand, effectively expanding the aperture of the sampling hole, so that the sample can be collected more comprehensively. When the sampling is completed, the reverse rotation of the sampling motor cooperates with the supporting effect of the spring, so that the drive sleeve can slide back and forth in the horizontal direction. In this process, the reciprocating movement of the drill plate effectively helps to pull out the sample in the sampling hole, greatly improving the efficiency and quality of sampling. The whole sampling process is easy to operate and has a high degree of automation, which not only reduces the labor intensity of the staff, but also significantly improves the safety and reliability of the sampling operation, providing strong technical support for oil exploration and exploitation;

[0058] 3. By setting the material guide assembly, when the drill plate of the oil sampling equipment is inserted into the inner wall of the oil well, the thorn rod is inserted into the inner wall of the oil well synchronously, which enhances the contact stability between the sampling equipment and the well wall. As the driving sleeve goes deeper, the extension plate slides smoothly along the material guide plate. When the sampling plate is pulled in the opposite direction, the thorn rod ensures that the end of the extension plate always fits closely to the inner wall of the oil well, which improves the efficiency and accuracy of sample collection. The sample can fall smoothly on the extension plate and slide smoothly into the material guide groove along its inclined surface and the guidance of the material guide plate, which not only simplifies the sample collection steps, but also reduces the loss and contamination risk of the sample during the transfer process.

[0059] 4. By setting up the collection component and the design of the partition, the samples entering the installation shell along the guide grooves at different positions are effectively separated, avoiding the confusion of samples and ensuring the purity of the samples and the accuracy of the analysis results. The guide motor can drive the three transmission rods and the spiral conveying blades to achieve synchronous rotation through the transmission of the driven wheel and the synchronous belt, ensuring the synchronous transportation of samples in each guide sleeve. Under the action of the spiral conveying blades, the samples can be smoothly transported from the bottom end of the guide sleeve to the top end, and accurately exported through the material port at the top end, and finally fall into the corresponding collection box, which provides great convenience for the staff to take materials.

Under the action of the partitions 1310, samples entering the mounting shell 131 along the material guide grooves 125 at different positions can be separated and correspond to different material guide sleeves 132. At the same time, the samples can enter the material guide sleeve 132 through the material port 135. At this time, the material guide motor 136 can drive the three transmission rods 133 and the spiral conveying blade 134 to rotate synchronously through the driven wheel 137 and the synchronous belt 138. Therefore, the sample in the material guide sleeve 132 can be transported from its bottom to the top, and can be guided out through the material port 135 at the top and fall into the corresponding collecting box 139.

[0077] The specific working principle of the present invention is as follows:

[0078] When the oil distribution sampling device for oil mining proposed by the present invention is used, the whole device can be transported to the oil well first, and the sampling plate 2 can be inserted into the inside of the oil well. The top of the sampling plate 2 is fixed by the mounting frame 1, and the mounting frame 1 can be fixed at the opening of the oil well by the mounting frames 14 on both sides. Then, according to the requirements of the sampling position, the electric push rod 7 can be turned on to drive the guide block 4 to slide in the guide groove 3, so that the position of the connecting plate 5, the sampling motor 8 and the driving sleeve 9 can be adjusted. After the adjustment is completed, the electric push rod 7 can be stopped and fixed. Then, the staff can manually push the sampling plate 2 to slide on the inner side of the mounting frame 1, and the sampling motor 8 can be turned on synchronously. When the sampling motor 8 is turned on, it can drive the driving sleeve 9 to rotate and cooperate with the sliding of the sampling plate 2 to make the driving sleeve 9 inserted into the inner wall of the oil well;

[0079] During the process of inserting the drive sleeve 9 into the inner wall of the oil well, the electric push rod 111 can be opened to extend it and drive the support rod 1110 to slide along the through-hole 112. The connecting ends of the support rod 1110 and the mounting plate 119 are both set as inclined surfaces. Under the action of the inclined surface, the support rod 1110 can lift the mounting plate 119, the fixing frame 118 and the drill plate 113 when sliding. At the same time, the guide frame 115 can slide along the fixing plate 114 through the cooperation of the slider 117 and the guide opening 116 to realize the gradual expansion of the three drill plates 113, so as to expand the aperture of the sampling hole. When the drive sleeve 9 is fully inserted into the inner wall of the oil well, the sampling motor 8 can be reversed. When the sampling motor 8 rotates forward, the vertical surface of the driving block 102 in this direction is opposite to the transmission block 104, so When the driving block 102 contacts the transmission block 104, the transmission block 104 and the transmission plate 103 can be driven to rotate, and the driving sleeve 9, the spring 108 and the annular plate 107 can be driven to rotate synchronously. When the sampling motor 8 is reversed, the inclined surface of the driving block 102 in this direction is opposite to the transmission block 104. Therefore, when rotating, the transmission block 104 and the transmission plate 103 can be pressed by the inclined surface. With the support of the spring 108, the transmission plate 103 and the driving sleeve 9 can slide back and forth in the horizontal direction along the support plate 105. When the sampling motor 8 is reversed, the staff can pull the sampling plate 2 in the opposite direction to move the driving sleeve 9 out of the sampling hole, and with the reciprocating movement of the drilling plate 113 on the driving sleeve 9, the sample in the sampling hole can be pulled out through the drilling plate 113.

[0080] When the drill plate 113 is inserted into the inner wall of the oil well, the thorn rod 124 at the end of the extension plate 123 can be synchronously inserted into the inner wall of the oil well, and with the insertion of the drive sleeve 9, the extension plate 123 can slide along the guide plate 122 to reduce the length of the two, and when the sampling plate 2 is pulled in the opposite direction, due to the fixing effect of the thorn rod 124, the end of the extension plate 123 can always fit the inner wall of the oil well, so the sample in the sampling hole can fall onto the extension plate 123, and the extension plate 123 and the guide plate 122 are inclined, so the sample can slide along the extension plate 123 and the guide plate 122 into the guide groove 125, and under the action of gravity, the sample can fall into the mounting shell 131 at the bottom end of the sampling plate 2 through the guide groove 125;

[0081] Under the action of the partition 1310, samples entering the mounting shell 131 along the material guide groove 125 at different positions can be separated and correspond to different material guide sleeves 132. At the same time, the samples can enter the material guide sleeve 132 through the material port 135. At this time, the material guide motor 136 can drive the three transmission rods 133 and the spiral conveying blade 134 to rotate synchronously through the driven wheel 137 and the synchronous belt 138. Therefore, the sample in the material guide sleeve 132 can be transported from its bottom end to the top end, and can be exported through the material port 135 at the top and fall into the corresponding collection box 139. The staff can directly take the sample in the collection box 139, which is more convenient to use. At the same time, after the sampling of the sampling plate 2 is completed once, the direction of the sampling plate 2 and the position of the driving sleeve 9 on the sampling plate 2 can be readjusted, so that sampling processing can be directly performed on different positions of the oil well.

[0082] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
