摘　　要：抽油机井管杆偏磨是国内外各大油田普遍存在的问题,根据临盘油田338口偏磨井的生产数据,借助抽油杆受力状况分析,较全面地分析了油田高含水开发后期,抽油机井出现管杆偏磨的原因和机理,为选择合理的管杆偏磨综合防治措施奠定了基础。Issue of eccentrically worn between a pumping rod and casing strings mostly exists in each major oilfield worldwide. Regarding this scenario, based on production data acquired from 338 wells involved eccentrically worn in the Linpan Oilfield, the worn reasons and mechanisms in high water bearing yield terms are analyzed by force analysis, which lay the foundation of choosing reasonable prevention and reparation for such issue.
