Description

Technical Field

[0001] The utility model relates to the technical field of oil mining sampling, in particular to a sampling device used for oil mining. Background Art

[0002] Oil extraction refers to the act of digging and extracting oil from places where oil is stored. Oil is a fluid mineral buried deep underground. When oil is extracted, oil testing is required on a regular basis to detect the quality of the oil. Before testing the oil, a small amount of oil needs to be taken out of the oil well. When sampling oil, a sampling device is required.

When it is necessary to extract oil at different depths in the oil well, multiple samplings are required. The operation is very cumbersome and it is not convenient to quickly sample oil at different depths in the oil well. Therefore, we propose a sampling device for oil extraction to solve the above problems. Utility Model Content
