Description

Technical Field

[0001] The utility model relates to the technical field of petroleum sampling, in particular to a water well water extraction device. Background Art

[0002] Petroleum, also known as crude oil, is a viscous dark brown liquid fuel extracted from deep underground. After being extracted from oil wells, petroleum is transported using oil pipelines. During the process of oil extraction, it is necessary to sample the oil and test the sampled oil in order to test various parameters such as the water content during crude oil transportation.

[0003] Most of the existing oil sampling methods mainly set valves on the transmission pipeline, and sample the oil by opening the valve. This method can easily lead to excessive oil pressure in the transmission pipeline, which can easily cause oil spraying during the sampling process. At the same time, the sampled oil is mostly transported in metal pipes, etc., and the open end of the metal pipe needs to be sealed. If it is not sealed well, the sealing cover is likely to fall off, and dust and other debris may contaminate the sampled oil, which can easily cause inaccurate test results. It is necessary to design a water well water extraction device to solve the above-mentioned problems. Utility Model Content

[0014] Furthermore, support columns are provided at both the left and right ends of the inner middle part of the sample box;

[0015] Through the above technical solution, when the bottom end of the seal contacts the support column, the hole formed between the seal and the empty groove can allow oil to pass through.

[0022] 2. In the utility model, the telescopic rod drives the sample box to move downward, and the spring pushes the seal upward to seal the upper part of the sample box. After the sealing cover on the upper part of the sample box is installed, it is convenient to transport the sample box. During the transportation process, the oil in the sample box will not spill, and dust and other debris will not enter the oil to pollute it, thereby increasing the protection of the oil sampled in the sample box.
