摘要
根据动力学普遍原理、考虑井眼轨道、抽油杆柱构成、抽油杆与油管的滑动磨擦力及油液的内摩擦力，采用微元矢量分析方法建立了定向水平井抽油杆柱纵向振动的微分方程，并分别给出了动态参数诊断与预测的定解条件。
Abstract Differential equations of longitudinal vibration of rod string and boundary conditions for the prediction and diagnosis of the behavior of sucker rod pumping system in directional and horizontal wells have been established by taking into account of well tra jectory , constituents and weight of rod string. friction force between rod string and tubing,viscous force of crude oil,etc.SUBJECT TERMS:sucker rod pumping,diagnosis,prediction, design,mathematical model
