Technical Field

[0001] The present application relates to the field of multiphase flow experiments, and in particular to a multiphase flow experiment device. Background Art

[0002] Complex pipelines in the petroleum industry are usually composed of various pipes and fittings connected in series or in parallel. Oil-water two-phase mixed flow is the most common flow form. Current research on complex pipelines is mainly limited to single-diameter pipelines. Based on pipeline series and parallel theory, flow pattern transition criteria, dual-fluid model and homogeneous flow model, a unified mechanism model of oil-water two-phase flow in complex pipelines has been established, also known as a multiphase flow experimental device.

[0003] The multiphase flow experimental device is generally composed of an oil storage tank, a water storage pipe, a gas storage tank, a mixing pipeline, an experimental detection pipeline, an oil-water separation tank, etc. When conducting experiments on multiphase flows such as oil, water, and gas, the oil in the oil storage tank, the water in the water storage tank, and the gas in the gas storage tank are generally injected into the same mixing pipeline. The liquids are mixed as they flow through, and then flow into the experimental detection pipeline to record the experimental values.

[0004] When injecting media in various states into a mixing pipeline, a multi-directional guide plate is generally installed directly in the mixing pipeline. During the flow of the medium, it directly hits the guide plate in the mixing pipeline. The guide plate changes the flow direction of the medium and allows the various media to mix. Although this mixing method can quickly mix various media, the medium may be unevenly mixed and the mixing efficiency is poor during the process of flowing through the mixing pipeline due to the short mixing pipeline. If uniform mixing is required, a longer mixing pipeline must be set up, and the installation may occupy a large space. Summary of the invention
