大庆油田进入特高含水期 ,抽油机井杆管偏磨井数不断增加 ,杆断比例上升 ,检泵周期缩短 ,作业费用增加。通过抽油机井杆管偏磨因素分析 ,提出了响应的预防措施 ,对减少杆管偏磨 ,降低杆断比例 ,提高泵效 ,延长检泵周期是十分必要的。在有杆抽油井中 ,当抽油机驴头下行时 ,抽油 Daqing Oilfield entered the period of ultra-high water cut. The number of partial wells in the rod wells of pumping units continued to increase, the percentage of rod breakages increased, the inspection pump cycle shortened, and the operating costs increased. According to eccentric wear factor analysis of pumping shaft, the measures to prevent response are put forward. It is necessary to reduce the partial wear of rod, reduce the proportion of rod break, improve the pump efficiency and extend the inspection cycle. In rod pumping wells, when the pumping unit head down, pumping oil
