摘要
本文根据中原油田主力油层高含水而非主力油层却没有得到充分动用的特点 ,研究出一套适合中原油田老井二三类非主力油层特点的重复压裂工艺技术 ,以最近压裂的两口井为例 ,提出并应用了提高砂比、强化破胶及快速返排等一系列技术措施 ,取得了较好的效果 ,从而达到了改善油水剖面、充分开发老井二三类非主力油层、提高采收率。
According to the feature that the main production zone is high water cut, minor production zone isnot fully yet, We have studied a series of refrac-processes that are fit for minor production zone in Zhongyuan Oilfield. Taking two fractured wells for examples, we have applied a series of technologies such as enhancing sand ratio, forced breaking of emulsion and rapid flowing back etc. and received better results. Thus we will reach the destination of improving oil-water profile, fully developing minor production zone, enhancing oil recovery, stabilizing oil and controlling water.
