Problems solved by technology

[0007] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the downhole sampling device used for oil exploitation does not have an automatic timing sampling structure, which is not convenient for the user to detect and compare the oil at different times, which may easily lead to detection results There are large errors, and it is impossible to process the oil and gas, which may easily lead to oil and gas poisoning of the user during the detection. Therefore, the safety of the device is not ideal, and there is no protection mechanism for power equipment or other auxiliary structures, which is not convenient for users. Problems with carrying and storing power equipment or other auxiliary structures

Embodiment 1

[0035] see Figure 1-6, the present invention proposes a kind of downhole sampling device for oil exploitation, including protective shell 2, bottom plate 9 and oil pump 18, the bottom of bottom plate 9 is fixedly installed with wheels 8, and the number of wheels 8 is four, A protective shell 2 is fixedly installed on the top, a controller 1 is fixedly installed on the surface of the protective shell 2, a limit block 13 is fixedly installed on both sides of the top of the protective shell 2, and a protective box is movably installed on the top of the protective shell 2 between the limit blocks 13 15. The surfaces on both sides of the protective box 15 are fixedly installed with movable blocks 12, and the movable blocks 12 overlap with the limit blocks 13. The inside of the protective box 15 is provided with a temperature insulating layer 16, and the interior of the temperature insulating layer 16 is provided with a moisture-proof layer. 17. A retractor 4 is fixedly installed o...

Embodiment 2

[0038] see Figure 2-6 , a kind of downhole sampling device for oil exploitation proposed by the present invention, compared with the first embodiment, this embodiment also includes: a protective door 7 is movably installed on the surface of the protective shell 2 at the bottom of the controller 1, and the protective door 7 is A handle 701 is fixedly installed on the surface, and the user pulls and opens the protective door 7 by holding the handle 701, and then the collection bottle 20 containing the oil can be taken out, and the oil inside is detected. A fixing member 101 is fixedly installed, and a fixing bolt is movably installed between the fixing member 101 and the protective shell 2. The contact area between the controller 1 and the protective casing 2 is increased by the fixing member 101. The protective shell 2 is fixed, thereby increasing the stability of the installation of the controller 1. A box door 1501 is movably installed on the surface of the protective box 15...

Abstract

The underground sampling device comprises a protective shell, a bottom plate and an oil well pump, the protective shell is fixedly mounted at the top of the bottom plate, a protective box is movably mounted at the top of the protective shell between limiting blocks, a collecting bottle is movably mounted in a placement box, and an oil guide pipe is movably mounted in the protective shell at the top of the collecting bottle. An electromagnetic valve is fixedly mounted on the periphery of the oil guide pipe, a fan is fixedly mounted at the top of the partition plate, an air guide pipe is arranged between the fan and the collecting bottle, and a particle filter screen is movably mounted in the protective shell on the other side of the activated carbon filter screen. Petroleum is automatically collected and sampled in different time periods, so that a user can conveniently detect and compare the sampled petroleum, the detection error is reduced, the oil gas can be treated, the environmental protection effect and safety of the device are improved, the user can conveniently carry and protect power equipment or other auxiliary structures, and the device is suitable for popularization and application. And the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a downhole sampling device for petroleum exploitation. Background technique [0002] Oil extraction refers to the act of excavating and extracting oil in places where there is oil storage. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. The oil is deeply buried in the well. In the underground fluid minerals, the oily liquid minerals produced in nature were originally called petroleum, the combustible gas was called natural gas, and the solid combustible mineral was called asphalt. These compounds are related to each other in terms of causes, so they are collectively referred to as petroleum. During oil exploration, regular petroleum testing is required to detect the quality of the oil. Before testing the oil, a small amount of oil needs to be removed from the...
