摘要
借助有限元法建立了斜直井抽油杆系统的动力方程，该模型既适于单级杆柱，也适于多级杆柱。该模型经修改后还可用于任意斜井的抽油杆分析。通过求解该方程，可计算各节点不同时刻的位移，计算出载荷，绘出各节点功图。文中介绍了求解该方程的一些特殊处理，可节省微机内存，适于微机上运算。
The dynamic equation of sucker rod for slant straight well has been established using finite element method. It is suitable for single and multiple stages sucker rod. Being amended,it can be used for sucker rod analysis of any slant well. By this equation,we can calculate the displacement,load and dynamometer diagram at every rod node and any time.This paper also introduces the method to solve the equation,which can save memory of microcomputer.
