基于CFD仿真的射流泵流场数值模拟研究
Numerical Simulation Study of Flow Field in Jet Pump Based on CFD
摘要
Abstract
The hydraulic jet pump is a commonly used mechanical drainage and production technique for high-wa-ter-production gas wells,but its application suffers from issues such as high energy consumption and costs.To ad-dress these problems,numerical simulation research on the pneumatic jet pump was conducted.First,theoretical studies were performed on the characteristic parameters,characteristic equations,and control equations of the pneumatic jet pump to determine the main parameters to establish a fluid domain model.Then,numerical simula-tions were carried out using the CFD simulation software,with the operational and structural parameters of the pneumatic jet pump seving as base variables.The numerical simulation results show that the difference between the inlet pressure of the working fluid and the inlet pressure of the suction is positively correlated with parameters such as the flow velocity and pressure in the flow field.Increasing the angle of the diffuser tube is certain improvement effect on the gas-liquid retention phenomenon;optimizing the throat-to-nozzle distance significantly enhances gas flow veloc-ity and pump pressure.After applying the pneumatic jet pump process in Well A,the production time rate increased to 100％,the injection pressure decreased by 76.2％,and the energy consumption was reduced by 48.6％.关键词
