摘　　要：本文系统讨论了抽油机井杆管磨损形式,根据杆管磨损的截面的几何关系,分别建立斜井狗腿度导致的磨损段、末端失稳螺旋屈曲磨损段以及旋转油管情况下的杆管磨损深度和磨损截面积之间关系的理论方法,建立抽油机井杆管摩擦磨损计算模型,可以在已知抽油机井侧向载荷分布的基础上计算不同时间的杆管磨损深度和截面积,为判断油管磨漏、杆柱接箍剩余截面积等提供依据。应用该模型编制的成果软件在我国油田对比分析20井次,证实其计算的磨损是比较可靠的。Base on the wearing section geometrical relation of rod and tubing,This paper set up a model to calculate the relation of depth of wear and wearing section area for position of dogleg and Spire inflection, and for tubing circumrotate state. Those calculattion must base on the distributing of lateral load. The model can provide a referrence to make sure that whether the tubing have leaking or when it will leak. Can provide a referrence to make sure that the residual area of a collar or rod. Base on this model,can get a software to calculate wearing rate of a sucker rod pump and the cycle of borehole operation. Application the software to in 20 wells prove the model is reliable.
