摘要
本文介绍了大位移井的定义、完井技术及采油工艺技术。大位移井眼剖面的优化设计及悬链线的概念,在大位移井的固井完井施工中,由于大位移井延伸井段长,采用了套管漂浮接箍和套管漂浮技术。大位移井中的电潜泵机组应用于接近水平的井段中,井眼净化工作尤为重要,同时简要介绍了几种不同的油层打开方式。
This paper addresses the definition of extended reach well,completion technology,oil recovery process,well profile optimization,and the concept of catenary.In cementing operation of extended reach well,casing floating collar and casing floating technology are used.The ESP unit of extended reach well is used in nearly horizontal interval.Hole cleaning is especially important.Several methods of drilling in reservoirs are also introduced.
