流速对潜油电机壳体腐蚀与冲蚀的研究

Research of Velocity on Electric Submersible Motor Shell Corrosion and Erosion

摘要: 利用Solidworks软件，建立了潜油电机外形的仿真模型。利用Fluent软件，建立了潜油电机外表面的流场域和边界条件，并进行了网格划分。数值模拟结果表明，在潜油电机外表面与套管内壁的环空处的流速极大，并且在变径处产生一定的湍流，加剧了对潜油电机壳体金属表面的腐蚀与冲蚀。

Abstract: The simulation model of electric submersible motor configuration is built by solidworks software. The flow field of outer surface of electric submersible motor and boundary conditions are also established by means of fluent software. At the same time, the grid division of model is carried out. Numerical simulation results show that the velocity, which is located in the place between the outer surface of electric submersible motor and casing inwall hohlraum, is maximum, and there is some turbulence in changing diameter, which increases the corrosion and erosion of electric submersible motor shell.
