摘　　要：偏磨是由水平正压力造成的 ,与半干摩擦力关系不大 ;中和点上下抽油杆柱都会发生不同程度的偏磨 ,80 0m以上的抽油杆一般不会发生偏磨 ;文章介绍了中和点上下扶正器安装位置及间距的计算公式。现场应用 ,收到了防止管杆偏磨 。The off-center wear of sucker rod arises from horizontal normal pressure.It occurs in up and down location of neutral point in rod string.The sucker rods over 800m don't result in off-center wear.The paper presents the calculation formulas of mounting location and spacing on centralizer.Through field application,it effectively prevents off-center wear of sucker rod,and prolongs pump detection period.
