摘要
为了解决抽油机与电机的合理节能选配问题,在有杆抽油系统动态参数的预测模型基础上,对游梁式抽油机的几何和运动模型进行修正和扩充.分析推导井口悬点载荷的特性、变速器的传动特性和电机与其耦合后的转矩特性,建立完整的抽油系统动力耦合关系仿真模型.在悬点载荷仿真模型上,对静载荷及动载荷进行深入分析,提高了仿真模型的准确性.以典型井的参数为例进行了计算,验证了该模型的准确性.
To select a proper electrical machine and control strategy,based on dynamic parameters predicting model of oil-pumping,the geometry model and movement model are modified and expended.The characteristic of suspension load,driving characteristic of gearbox and coupled torque characteristic of electrical machine are analyzed,as a result,a dynamic coupled model for oil-pumping system is built,and its calculation accuracy is increased by deep analysis of static and dynamic suspension load.Finally,a typical system is selected to be simulated,and the correctness of the model is proved.
