摘　　要：在有杆泵抽油井的生产过程中管杆偏磨是一个普遍存在的问题。影响油井管杆偏磨的因素很多,通过分析发现对于定向斜井来说,油井的井眼轨迹是影响油井偏磨的最重要的因素。对大量的资料分析得出了油井偏磨与井斜角、全角变化率、井身剖面、中和点位置的关系,并总结了油井管杆的偏磨规律。Sucker rod's eccentric wear is a common problem in oil production process and is the main reasons of pump inspection in oil wells.The eccentric wear brings a large number of sucker rod and oil tube's abandonment every year.Most of wells are directional well in JOECO because of Jiangsu oilfield special geologic features.Factors of influence eccentric wear are numerous and the well track is the most important one.Based on plenty of well data,this paper got the relationship between eccentric wear and hole angle,rate of over-all angle,well profile,and neutral point's position and summed up the rules of eccentric wear.
