摘要

In order to complete the numerical simulation on intemal flow and operating characteristics of down hole multiphase pump compress unit,establishing perfect finite element model,the three-dimensional turbulent current fields inside the impellers of compression unit for down hole multiphase pumps were simulated by using ANSYS.The calculation of multiphase flow is based on the standard k-ε turbulent current model.Reference information for the improvement of the pump can be obtained by the analysis of the flow of gas-oil in the channel of pump.Based on the finite method,we analyzed several situations in a pumping period.The velocity and liquid pressure distributing of sucker rod pump is studied in this paper,which may offer some evidences for the engineering design of sucker rod pump.
