Description

technical field [0001] The invention relates to the field of testing properties and solubility of single-phase / multi-phase fluids under high temperature and high pressure, in particular to a comprehensive tester for high-temperature and high-pressure multi-phase fluids. Background technique [0002] The properties of multiphase fluids, especially the properties of multiphase fluids under high temperature and pressure are natural gas and CO 2 The basis of gas accumulation research. Due to different temperature and pressure, natural gas and CO 2 The properties and solubility of natural gas vary greatly, so it is necessary to quantitatively analyze the factors affecting the properties and solubility of the fluid to study natural gas and CO 2 migration and accumulation. Therefore, the high-temperature and high-pressure multi-phase fluid comprehensive tester is an indispensable equipment for the research on the properties and solubility of high-temperature and high-pressure mu...

AI Technical Summary

Problems solved by technology

[0004] So far, with regard to hydrocarbons, CO 2 The temperature and pressure conditions of the property test equipment are low and the test accuracy is not high, it is difficult to meet the needs of gas properties and solubility research in deep-sea accumulations, and hydrocarbons, CO 2 There are not many data on the properties such as phase state and solubility in formation water

It is difficult to test the solubility under high temperature and high pressure, which requires high equipment, and the accuracy is difficult to achieve. The risk factor is high in the high temperature and high pressure test of methane, and there is no suitable testing equipment on the market at present.
