摘　　要：有杆泵采油系统中的扶正器对整个采油系统稳定正常工作至关重要,抽油杆扶正器断脱事故频繁发生,严重影响了油井的正常生产,增加了维修费用和生产成本。本文通过接触有限元分析方法,用ANSYS参数化设计语言编写了抽油杆柱扶正器有限元分析的命令程序流,分析了扶正器工作状态下的受力,并对结构进行了优化,提出了改进意见。The centralizer is very important in the rod pump production system for the stable and normal operation of the whole production system. The disconnection accident of sucker rod centralizer occurs frequently,which seriously affects the normal production of oil wells and increases the maintenance cost and production cost.In this paper,through the contact finite element analysis method,the command program flow of finite element analysis of sucker rod string centralizer is compiled with ANSYS parametric design language,the force under the working state of the centralizer is analyzed,the structure is optimized,and the improvement suggestions are put forward.
