针对油田特高含水阶段电动潜油离心栗叶轮冲蚀磨损问题,采用RNG k-ε湍流模型和离散相模型并利用SIM-PLEC算法进行求解,实现对电潜栗冲蚀磨损的数值模拟,并研究工况参数和叶片结构参数对电潜栗叶轮冲蚀磨损的影响.结果表明：叶轮叶片吸力面是叶轮冲蚀磨损严重区域;随着砂粒浓度的升高及叶轮转速的提高,叶轮磨损速率增大;随着粒径及出口安放角的增加,叶轮磨损速率先升高后降低;叶轮平均磨损率随着进口安放角的增加而降低....

bIn order to solve the erosive wear problems in the impeller in the high water-cut stage,the RNG k - ε turbulence model,discrete phase model and SIMPLEC algorithm are employed to realize the simulation of an electric submersible pump＇s （ESP） erosive wear. The effects of the working condition and structural parameters of the ESP are also studied. The results show that the concave side of the impeller＇s blade is a serious eroded area. With the increases of the sand volume fraction and the impeller speed, the impeller＇s wear rate goes up. With the increase of the particle size and outlet angle, the wear rate firstly rises then reduces. Finaly,the impeller＇s average wear rate reduces with the increase of the inlet angle.
