Description

An oil extraction sampling device Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically to an oil extraction sampling device. Background Technology

[0002] Petroleum, a primary target of geological exploration, is a viscous, dark brown liquid known as the "blood of industry." Petroleum reserves exist in parts of the upper crust and are mainly composed of a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petrochemical theorists believe that petroleum is generated from carbon within the Earth's crust, is unrelated to biological processes, and is renewable. Petroleum is primarily used as fuel and gasoline, and is also a raw material for many chemical industrial products, such as solutions, fertilizers, pesticides, and plastics.

[0003] In the prior art, CN220599792U discloses an oil drilling sampling device. Although the above-mentioned prior art has achieved oil extraction, in actual use, oil often contains solid impurities such as sand and rock cuttings. If unfiltered fluid is directly extracted, these impurities may cause blockage of sampling pipes, valves or pumps, or even damage precision components, affecting sampling efficiency and equipment life. Furthermore, impurities in the oil fluid can interfere with the test results after being mixed into the sample, which greatly affects subsequent testing work and has poor practicality. In view of this, we propose an oil extraction sampling device to solve the above problems. Summary of the Invention

[0037] Working principle:

[0038] When using this oil extraction sampling device, the device is first stabilized and limited by the setting of the fixing component 17. Then, the drilling operation is realized with the cooperation of the drive component 24 and the motor 18. When it is necessary to sample the oil material around the sampling chamber 4, the electric push rod 5 inside the drill pipe 3 is activated. At this time, the electric push rod 5 will drive the push plate 6 to slide inside the sampling chamber 4. The movement of the push plate 6 will drive the plug 7 to move. At this time, the plug 7 will slide inside the inlet 8, and the filter plate 11 will also separate from the sealing plate 15. At this time, the oil around the sampling chamber 4 will be filtered by the filter plate 11 and enter the interior of the fixing ring 9. After the plug 7 drives the fixing ring 9 to descend until the outlet 12 is no longer located inside the inlet 8, the filtered oil will enter the interior of the sampling chamber 4 through the outlet 12, thus achieving the filtration of the oil.

[0039] As the sealing ring 10 descends, the sealing ring 16 gradually contacts and presses against the upper surface of the sampling chamber 4, thereby achieving a secondary seal on the liquid inlet 8.

[0040] When sampling is not required, the plug 7 will be located inside the inlet 8 to achieve a seal, and the sealing ring 10 will contact the sealing plate 15. At this time, the sealing plate 15 will seal the filter plate 11, thereby ensuring the filtration effect of the subsequent filter plate 11.

[0041] After drilling and sampling are completed, the drill bit 19 is reset, and then the pump inside the water tank 21 is started. At this time, water will enter the nozzle 22 through the water pipe 23 and spray out, thereby flushing the drill bit 19.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
