Abstract

The invention provides a test device for studying the change law of the flow field in the pipeline, which includes: a gas storage tank for storing gas; The gas tank is connected to the gas supply pipeline; the liquid supply pipeline, the liquid storage tank is connected to the liquid supply pipeline; the steady flow pipeline, the steady flow pipeline is connected to the outlet end of the gas supply pipeline and the outlet end of the liquid supply pipeline; The test pipeline, the test pipeline includes an ascending section, a descending section and an inclined section, the inlet end of the test pipeline is connected with the outlet end of the steady flow pipeline, and the outlet end of the test pipeline is connected with the liquid storage tank; multiple pressure sensors, Pressure sensors are arranged on the ascending section, the descending section and the inclined section. The invention solves the problem that the test method in the prior art cannot fully and accurately test the change of the flow field in the actual pipeline.

Description

technical field [0001] The invention relates to the technical field of pipeline flow field research, in particular to a test device for studying the change rule of the flow field in a pipeline. Background technique [0002] In recent years, the production of some oil wells is at the end of the life cycle. During the production process of the oil wells after water injection and pressurization, the water content in the medium is very high, and the transmission medium in the oil pipeline often contains a certain amount of water. When the acidic components in the medium are combined with water, it is very easy to cause serious corrosion to the inner wall of the pipeline. Therefore, the accumulation of water in the pipeline plays a major role in the corrosion of high water content crude oil pipelines. The internal flow pattern changes in the spanning section and the inclined section are more complicated. Different flow velocities and medium moisture content will have a significan...
