| 摘 要： | 根据定向井中抽油杆柱的实际工作状态，综合考虑了抽油杆柱刚度、油液粘滞阻力、村眨之间库仑摩擦力、井眼轨迹等因素的影响，从空间曲杆受力和力矩平衡原理出发，应用微元矢量分析理论，建立了定向井吸杆抽油系统诊断力学模型。

| Abstract: | According to the real working condition of the sucker rod in directional wells,this paper takes the effect of the following factors into consideration,bending stiffness of the rod string,viscous damping force of fluid,colomb friction force acting on the string from the tubing,trajectory of the wellbore etc.,and bases on the equilibrium principle of force and monent acting on the spatial cured rod and the analytical method of vector,then the mechanics model for diagnosis of sucker rod pumping system for directional wells is derived. |
