Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary sampling, and more particularly to a stable support type oilfield geological auxiliary sampling device. Background Art

[0002] Stable support type oilfield geological sampling equipment plays an important role in oilfield geological exploration and development. Its main use is reflected in multi-depth sampling. Some stable support type sampling equipment also has a lifting structure, which can realize the drill bit sampling of geological layers at different depths, improving the comprehensiveness and accuracy of sampling.

[0003] In the existing public documents, the patent with patent announcement number CN219798791U discloses a geological multi-layer sampling device for oilfield exploration. The sampling auxiliary device is used to adjust the position of the driving mechanism through a lifting mechanism to enable the high-speed rotating sampling head to explore and sample the oilfield geology downward. The lifting mechanism includes a gantry, and a secondary lifting component is arranged in the middle of the top of the inner cavity of the gantry, and the bottom end of the secondary lifting component is connected to the top surface of the driving mechanism. The utility model can not only explore and sample the oilfield geology, but also reduce the overall occupied space size when the equipment is moved, so that it is convenient for users to carry the equipment. However, the technology still has the following problems when used.

[0004] During the oilfield geological auxiliary sampling process, the drill bit needs to go deep into the oilfield geology to achieve drilling and auxiliary sampling. When the drill bit encounters the oilfield geological layer, it will produce a moving collision. At the same time, because the drill bit is long, the distance between the driving end and the other end is long, which causes the drill bit to be offset and tilted when sampling under the action of centrifugal force. It is difficult to make the drill bit position stably support auxiliary sampling according to the specified position, and the auxiliary sampling stability is poor. Therefore, a stable support type oilfield geological auxiliary sampling equipment is needed. Summary of the invention

[0038] The working principle of the stable support type oilfield geological auxiliary sampling equipment of the present invention is as follows:

[0039] Step 1: When the position is stabilized, the reinforcing block 12 is supported by the sleeve block 11, and the reinforcing block 12 supports the slide frame 20. The reduction motor 22 drives the bidirectional screw 21 to rotate, and the bidirectional screw 21 drives the two threaded sleeves 24 to approach each other under the action of the thread transmission force, and the bidirectional screw 21 rotates on the sensing end of the torque sensor 23. When the torque value sensed by the torque sensor 23 is the same as the torque value set by the controller 18, the reduction motor 22 is started by the controller 18 to install the specified torque to realize the driving operation. At the same time, the threaded sleeve 24 drives the pressure ring 25 to move down, and another threaded sleeve 24 drives another pressure ring 25 to move up. The pressure ring 25 drives multiple bearing sleeves 26 to move down, and the bearing sleeve 26 drives the extrusion ball 27 to move down. Multiple extrusion balls 27 are limited on the upper surface of the bearing groove ring 6, and multiple extrusion balls 27 below are limited on the lower surface of the bearing groove ring 6, so that the upper and lower surface limit operations of the pressure ring 25 are realized.

[0040] Step 2, during the stable support linkage, the controller 18 is supported by the mounting seat 19, the mounting seat 19 supports the guide ridge 17, the controller 18 starts the lower piezoelectric cylinder 16, and the guide ridge 17 supports the lower piezoelectric cylinder 16, the lower piezoelectric cylinder 16 pushes the guide sleeve 15 to move downward, the guide sleeve 15 slides down along the outer wall of the guide ridge 17, and at the same time the guide sleeve 15 drives the reinforcement plate 10 to move downward, the reinforcement plate 10 drives the sampling motor 13 to move downward, the sampling motor 13 drives the sleeve block 11 to move downward, the sampling motor 13 drives the rotating rod 14 to move downward, the rotating rod 14 drives the auxiliary sampling tube 1 to move downward, the auxiliary sampling tube 1 drives multiple vertical scrapers 4 to rotate, and the auxiliary sampling tube 1 drives the stabilizing ring 2 to rotate, the stabilizing ring 2 drives multiple horizontal scrapers 3 to rotate. Thus, multiple vertical scrapers 4 and multiple horizontal scrapers 3 can drill the oil field geology, so that the inner wall of the auxiliary sampling tube 1 can perform sampling operations on the oil field geology, the stabilizing ring 2 drives multiple stabilizing columns 5 to rotate, the stabilizing column 5 drives the bearing groove ring 6 to rotate, the bearing groove ring 6 rotates stably inside the sleeve shaft ring 7, and the reinforcement plate 10 supports the connecting support block 9, the connecting support block 9 supports the support block 8, the support block 8 can provide stable supporting force for the sleeve shaft ring 7, and the bearing groove ring 6 can stably realize limited rotation inside the sleeve shaft ring 7.

[0041] Step 3: During the fluctuation detection, the reinforcement block 12 supports the adjusting electric cylinder 28, and the adjusting electric cylinder 28 drives the connecting column 29 to move downward, and the connecting column 29 drives the connecting block 30 to move downward, and the connecting block 30 makes the supporting sleeve 31 move downward, and the supporting sleeve 31 drives the distance sensor 32 to be located above the adjusting pressure ring 25. Then the controller 18 turns off the adjusting electric cylinder 28, so that the distance sensor 32 can be located at the specified position on the upper surface of the pressure ring 25. When the bearing groove ring 6 rotates, it will drive multiple extrusion balls 27 to rotate, and the extrusion balls 27 roll inside the bearing sleeve 26. At the same time, the threaded sleeve 24 supports the pressure ring 25, and the pressure ring 25 supports multiple bearing sleeves 26. The bearing sleeve 26 realizes limited rolling of the extrusion balls 27, so as to realize the limited rotation operation of the bearing groove ring 6. At the same time, the distance sensor 32 performs distance sensing on the upper surface of the pressure ring 25. When the distance value sensed by the distance sensor 32 is the same as the distance value set by the controller 18 , the controller 18 closes the regulating electric cylinder 28 , so that the bottom end of the auxiliary sampling tube 1 can be stabilized with a rotation support force, thereby preventing the bottom end of the auxiliary sampling tube 1 from shaking.
