根据动力学原理，考虑了斜井三维空间井眼轨迹和多级抽油杆构成，采用微元体方法分析了抽油杆受力状况，建立了计算斜井抽油杆柱不同位置处的摩擦力的方法和公式。实例井的计算结果与实际状况基本相符。

In consideration of 3D space well track and the multi-stage pumping rod structure in a deviated well,status of forces appliced on the pumping rod is analyzed by using infinitesimal method according to the dynamic principle,thus methods and formulea are established to calculate the friction forces on different positions of pumping rod in a deviated well.Calculated result is basically matched with that of actual well conditions.
