Abstract

The invention relates to a pipeline sampling device which comprises a housing, a sampling mechanism and a sphere rotating mechanism. The housing is provided with a channel, the sampling mechanism is installed on the side of the housing and used for performing sampling from a channel. The sphere rotating mechanism is installed at the upper portion of the housing and used for driving a sphere in thehousing to rotate in the channel, the sphere is provided with a main sphere pipeline and a side sphere pipeline, the side sphere pipeline is located on the side of the main sphere pipeline and is notcommunicated with the main sphere pipeline. The pipeline sampling device is high in sampling speed without the process of low-flowing-speed emptying, replacement and sampling of a conventional high-pressure sampler, the sampling time is shortened, the working efficiency is improved remarkably, and the safety is high. The sample obtained through the pipeline sampling device is all liquid in one pipeline, the actual situation of a medium in the pipeline can be fully reflected, and the pipeline sampling device has very good representativeness.

Description

technical field [0001] The invention relates to a pipeline sampling device, in particular to polymer injection oil recovery engineering in oilfields. Background technique [0002] There are roughly two types of existing sampling devices: one is an external valve that drills a small hole on the pipeline and welds the threaded joint on the pipeline. When sampling, connect a special sampling device to the valve, open the valve, and use a special sampling device Extract the sample and complete the sampling work (as attached figure 1 shown). The first disadvantage of this type of device is that it can only extract the medium close to the flow layer of the inner wall of the pipeline; in addition, the safety is poor. Using this kind of sampling device, because it is connected with the valve through threads, problems such as untightening, loosening, and misoperation may occur. In addition, the system pressure is relatively high, so safety accidents are prone to occur. [0003] An...
