辽河油田沈阳采油厂开发进入中后期,由于多种原因的综合作用,抽油机井偏磨井次逐年增加,加速了管杆泵的损坏,增加了采油的工作量和工作成本。本文通过现场数据分析、统计得出偏磨原因并针对种种原因做出相应对策阻止或延缓偏磨的发生。 Liaohe Oilfield Shenyang Oil Production Plant into the late development, due to a combination of a variety of reasons, pumping wells partial wear well times increased year by year, accelerating the damage to the pipe pump, increasing the workload and cost of oil production. In this paper, through field data analysis, statistical analysis of the reasons for partial wear and make corresponding measures for various reasons to prevent or delay the occurrence of partial wear.
