The device can simulate the multiphase flow of oil, gas, water and solid multiphase fluids and gas and liquid single-phase fluids in horizontal, vertical and inclined pipes under certain pressure and temperature conditions. It has simple structure, wide application range and easy operation. The advantage of convenience.

Description

technical field [0001] The invention relates to a temperature-controllable pressure-controlled oil-gas-water-solid multiphase pipeline simulation experiment device, and relates to the fields of development, storage and transportation of oil and natural gas. Background technique [0002] In the process of oil and natural gas development and transportation, because the products of oil and gas wells produced are often fluids with coexistence of oil, gas, water and solid media, gas-liquid-solid fluids often appear in horizontal, inclined or vertical pipelines and wellbores. , gas-solid, liquid-solid, liquid-liquid and other multiphase flow states. During the flow process in the pipeline or wellbore, with the change of pressure, temperature and pipeline inclination, phenomena such as slug flow and stratified flow will appear in the pipeline and wellbore, which will cause erosion and corrosion of the pipeline and wellbore, which are serious Threatening the safe operation of pipel...

AI Technical Summary

Problems solved by technology

[0003] Among the currently disclosed multiphase flow experimental loop devices, some devices (CN201410461202, CN201020579905) can perform gas, oil, and water multiphase flow simulation experiments, but the disclosed devices cannot simultaneously simulate horizontal, vertical, and inclined pipes. Oil, gas, water, and solid multiphase flow cannot be flexibly converted between oil, gas, water, and solid multiphase fluids and single-phase fluids such as gas and liquid, and it is impossible to control the temperature of the flow pipeline in sections, making it difficult to comprehensively Simulate the multiphase flow of different types of fluids in horizontal, vertical, and inclined pipes under varying pressure and temperature conditions
