1前言随着水平井、斜井、高含水井、低产井等类型油井的日渐增多,抽油机井杆管磨损问题已经成为困扰油井生产的主要问题之一。以高升采油厂雷家地区为例,初步统计有近60口井存在较严重的偏磨问题。油井磨损主要表现在管杆偏磨严重、检泵周期明显缩短、生产成本显著上升等方面,现阶段管、 1 Introduction With the increasing number of horizontal wells, inclined wells, high-water wells, low production wells and other types of wells, pumping rod wells wear has become a troubled oil production, one of the major problems. Taking the high oil production plant in Leijia region as an example, a preliminary statistics shows that there are more serious partial wear problems in nearly 60 wells. Oil well wear is mainly manifested in the serious eccentric tube wear, pump cycle was significantly reduced, significantly increased production costs, etc., at this stage pipe,
