Description

technical field [0001] The invention belongs to the technical field of oil production engineering, and in particular relates to an experimental device for studying the law of erosion and wear of a throttle valve. Background technique [0002] The throttle valve is a throttling device used to control the production of gas wells. During the testing and production of oil and gas wells, throttle valves of different specifications are required to control the production pressure difference and adjust the oil and gas production, which is critical for oil and gas production. During gas well production, when the gas flows through the throttle valve, the pressure difference at the throttle valve is large, the flow rate is high, and the flow state is relatively complex, which is prone to throttle valve erosion, especially for gas-solid particles containing solid particles. Two-phase flow, the erosion and wear phenomenon of the throttle valve is more and more obvious. Due to the large ...

AI Technical Summary

Problems solved by technology

On the one hand, the damage of the throttle valve has brought certain hidden dangers to the production safety; on the other hand, the frequent replacement of the throttle valve has seriously affected the production efficiency

However, at present, the erosion and wear mechanism of high-pressure gas-solid two-phase flow on the throttle valve is still unclear. The high-pressure gas on the well is mainly flammable and explosive gases such as methane, and indoor experiments are dangerous and difficult to operate. There are few experimental equipment that can Complete the erosion and wear experiment of this kind of high-pressure gas-solid two-phase flow on the throttle valve
