摘　　要：二连油田在阿南和蒙古林区块的开发井以Φ139.7 mm套管完井方式居多,在近几年老井挖潜改造的悬挂器固井施工作业中,遇到小间隙井眼固井施工困难的问题。为满足开发需要,引进了渤海钻探公司研发的BH-XGY系列Φ139.7 mm带顶封装置的尾管悬挂器。该悬挂器针对二连油田小间隙井眼的固井施工,从锥套结构导流设计、钻杆胶塞和尾管复合胶塞结构优化方面入手,改进了多项结构。通过理论计算和现场应用对比分析,解决了二连油田小间隙井眼固井作业中井筒循环压力高、胶塞碰压难、固井质量不高的技术难题,在现场施工中取得了良好的效果。Most of the development wells in Anan and Menggulin blocks of Erlian Oilfield were completed with Φ139.7 mm casing.In recent years,the problem of cementing in small gap hole was encountered in the hanging device cementing operation.In order to satisfy the requirements of development,Erlian oilfield introduced BH-XGY series Φ139.7 mm liner hanger with top sealing device developed by Bohai Drilling Company.Aiming at the difficult problem of cementing in small gap well in Erlian Oilfield,the hanger innovated and improved several structures from the aspects of cone sleeve structure diversion design, structure optimization of drill pipe rubber plug and liner compound rubber plug.Through the comparison and analysis of theoretical calculation and field application,the technical problems of high circulating pressure in well bore,difficult rubber plug bumping and poor cementing quality in small gap well cementing operations in Erlian Oilfield were solved and it has achieved good results in the field construction.
