Abstract

The invention relates to the field of oil field sampling, in particular to a sampler with a multipoint uniform mixing and collecting function for an oil field. The problems to be solved are as follows: the sampling uniformity is influenced by manual three-time crude oil taking quantity and sampling time change, the mixing is not uniform after sampling, and the detection result is influenced. According to the technical scheme, the sampler with the multipoint uniform mixing and collecting functions for the oil field comprises a mounting frame, a mixing tank and the like, a mixing tank is mounted in the middle of the upper surface of the mounting rack. Crude oil is sampled in a segmented three-time sampling mode, in the sampling process, automation is completely adopted, manual control is not needed, then manual sampling errors are eliminated, the amount of the crude oil obtained through three-time sampling and the sampling time are accurately controlled, it is ensured that the crude oil obtained every time is consistent with the oil taking time, and the sampling efficiency is improved. In addition, after sampling is completed, crude oil is accumulated and mixed, it is ensured that crude oil sampled three times is evenly mixed, and the accuracy of crude oil detection is improved.

Description

Technical field [0001] The present invention relates to the field of oilfield sampling, and more particularly to a sampler having a multi-point uniform mixing acquisition function in an oil field. Background technique [0002] During the observation process of crude oil, the quality of the crude oil produced at different times in the same place is different. Therefore, when sampling, the crude oil needs to be sampled multiple times. After the sampling is completed, the sample of the crude oil is mixed, so that When detecting the crude oil quality, ensure the uniformity of the sampling, and the results are accurately detected; however, when the prior art is sampling, it is generally sampled by the sampling personnel, and therefore, when sampling, due to manual operation, each crude oil The amount varies, it is not accurate enough, and each sample time has changed, resulting in different amounts of petroleum samplement from different time points, affecting the uniformity of the sam...
