摘　　要：对于在Ф139．7mm油层套管开窗侧钻下Ф101，6mm尾管完井的小间隙侧钻井，固井完井质量难以保证一直是困扰侧钻井开发的难题。为此研制了Ф（118—120）mm井眼水力扩张式裸眼扩孔器，并在官8—9K等小井眼侧钻井完井施工中实施了扩孔作业，取得了较好的效果，扩孔工具工作平稳，扩孔机械钻速接近裸眼钻进机械钻速的2倍，扩孔后平均井径为152．23mm，井眼质量较好，固井质量得到了保证。After window cutting sidetracking operation in 139.7 mm production casing and completing used 101.6mm liner,a small space sidetracking well began to form between the production casing and the liner.Completion and cementing quality of this type well is a difficult problem of sidetracking well development.Hydraulic expand open hole reamer which diameter ranges between 118～120 mm was developed by many years study and practice,and reaming work in Guan8-9K slim hole sidetracking well completion,and obtain favourable effect.During reaming work,reaming tool performance stabilization,reaming rate-ofpenetration is near to 2 times of open hole rate-of-penetration,and hole quality is all right.After reaming,The average well diameter is 152.23 mm,and well cementing quality gained guarantee.Reaming technolog succeeded in Guan8-9K sidetracking slim hole,and it has a instructed effect to latter slim hole sidetracking well completion technology.
