摘　　要：环江油田偏磨问题严重,为了解决油井偏磨问题,进行防磨工具配套综合研究,设计了油管导向短节、小直径内过流扶正器、同曲率内过流自旋式抽油杆扶正器综合防磨措施,防磨工艺计算与现场应用表明,油管导向短节锥度为1:50及长度为350mm时,小直径内过流扶正器外径为48mm,同曲率内过流自旋式抽油杆扶正器曲率为1/27、扶正块外径50mm时,综合防磨强,防磨效果明显,平均每口井每年可减少检泵次数2.51次,节约维护作业费用8.73万元,具有良好的推广应用前景和经济效益。Eccentric wear in oil wells is one serious problem in Huanjiang oilfield. In order to solve this problem,comprehensive anti-wearing tool kit,tubing steering sub design,inner overflow centralizers and calculation of anti-wearing technology in collaboration with on-site application are researched in this paper.
