摘要
油井开采后期 ,单井产量下降 ;以及部分探井、开发井由于各种原因在完井后没有获得油气流形成了低产井和无用的“空井”。有效地将这些资产盘活 ,变废为宝 ,使低产井成为高产井、“空井”成为高产油气井是投资石油勘探开发的目标。目前 ,西北石油局在塔河油田利用一口没有获得工业油气流的开发井通过侧钻获得了可喜的高产油气流 ,在该区探索出一条科学、高效开发奥陶系灰岩油气藏的新路 ,获得了极大经济、技术效益。
In later-period oil well development,individual-well producing rate is reduced.And for all kinds of causes,part exploration well and development well don't obtain oil & gas reserves to form low producing well and idle 'empty well'.How to effectively make low producing well and 'empty well' become high-yielding well is the object of petroleum exploration and development.At present,through sidetracking a low producing well,Northwest Petroleum Administration obtains high-yielding oil & gas stream in Tahe Oilfield and gets great economic and technical benefit.
