摘要
鱼骨型水平井是水平井技术的进一步延伸和发展,是油田用于改善开发效果和提高采收率的一种重要手段,新疆油田近年来开始将该技术运用于油田开发。从新疆油田已钻鱼骨型分支水平井情况来看,在开采初期单井产量非常高,但开采一段时间后产量骤减。本文针对这一现象,通过对新疆油田已钻鱼骨型水平井完井现状及存在问题进行分析,并结合其钻井特点,研究出一套鱼骨型水平井分支井眼下筛管完井工艺技术实施方案及其配套工具,并在此基础上提出了几种完井方案设想。
Fishbone well is a technology that further extension and development of horizontal well.It's a important way to improve the development effectiveness and enhanced oil recovery.Xinjiang Oilfield begun to apply the technology into oilfield development in recent years.The fishbone wells have been drilled in Xinjiang Oilfield, we come to conclusion that output of single well is very high at initial stage of production,but the productivity decreases rapidly after it has been produced in a period.Aiming at this phenomenon,this paper analyzing the completion status and problems of fishbone wells have been drilled in Xinjiang Oilfield,combining its drilling characteristics, excogitate a implementation scheme of completion technique and matching tools for branch hole of fish-bone well,then,the authors propose designs of completion technique.
