摘要
为了能够直观地研究抽油杆在井下变形情况,研制出抽油杆变形实验平台。该平台采用由PID控制的液压伺服加载系统,输出模拟抽油杆在井底弯曲变形时需要的轴向力与位移。为分析和提高伺服系统精度与稳定性,通过AMESim软件对加载系统进行建模、仿真,同时考虑了PID对系统误差调整的影响,最终获得合适的PID设置参数与液压系统方案,为抽油杆变形理论研究提供了精确、稳定的测试平台。
In order to visually study the deformation of the sucker rod in the downhole, the experimental platform for the deformation of the sucker rod is developed. Hydraulic servo system controlled by PID is adopted in the loading platform to output the axial force and displacement. To analyze and improve the accuracy and stability of the servo system, this paper considers the influence of PID on system error adjustment through AMESim software, and finally obtains the appropriate PID setting parameters and hydraulic system scheme, which provides the high precision and well stability platform for the theoretical study of sucker rod deformation.
