摘　　要：为了研究含气率对往复式油气混输泵排出性能的影响及转速、含气率、流量的相互关系,基于标准k-ε湍流模型和混合多相流模型,采用计算流体力学软件中的动网格技术和用户自定义函数,在介质含气率不同时对混输泵的排出过程进行三维动态仿真模拟。结果表明:介质增压速度、最大流量、平均流量与含气率成反比。根据转速、含气率、流量关系曲线调节转速,使泵的流量与抽油机流量相匹配,为往复式油气混输泵性能参数的选择及现场应用提供数据参考。In order to study the relationship among speed,gas volume fraction and flow rate,and the influence of the gas volume fraction on the discharge performance of the reciprocating oil-gas multiphase pump.This paper is based on the standard k-εturbulence model and mixture multiphase flow model.At the same time,the dynamic grid technology and UDF in the computational fluid dynamics software are used to perform three-dimensional dynamic simulation of the pump discharge process,when the gas volume fraction is different.The simulation results indicate that the speed of the medium pressurization,the maximum discharge flow rate and the average discharge flow rate in inverse proportion to the gas volume fraction.In addition,adjust the speed according to the relationship curve of speed,gas volume fraction and flow rate to match the flow rate of oil-gas multiphase pump with that of pumping unit.The results can provide data reference for the selection of pump performance parameters.
