Abstract

The invention belongs to the technical field of oil-gas separation test experiments in an oil and gas gathering and transportation system, and superficially relates to a foam fluid performance and defoaming separation effect test experimental apparatus and a method. The experimental apparatus comprises a foam generation module for generating foam fluid, an experiment loop for transporting the foamfluid and making the foam fluid fully develop in the loop, a foam performance test module for testing foam fluid performance, a foam separation processing module for separating the foam from the fluid and the gas, and a defoaming result evaluation module for testing and evaluating a defoaming result. In the method provided by the invention, the foam generation module internally generates different foam fluid, the foam fluid is transported to the foam performance test module and the different foam separation processing module through the experiment loop, and by the foam performance test moduleand the defoaming result evaluation module connected with the foam separation processing module, foam performance and the defoaming separation effect of the foam fluid can be measured.

Description

technical field [0001] The disclosure belongs to the technical field of oil-gas separation testing experiments in oil-gas gathering and transportation systems, and in particular relates to an experimental device and method for testing foam fluid performance and defoaming and separation effects. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] CO 2 Oil displacement is achieved by CO 2 injected into the oil reservoir and treated with CO 2 As an oil displacement agent, it can achieve the effects of reducing displacement resistance, reducing crude oil viscosity, promoting crude oil volume expansion and miscible effect in the process of crude oil collection to enhance oil recovery, and CO 2 The rational use of gas can also reduce greenhouse gas emissions, which has broad application prospects. [0004] CO 2 Higher solubility in both oil an...
