海拉尔油田南屯储层压裂施工分析及处理措施

Fracturing operation analysis and treatment measures of Nantun reservoir of Hailaer oilfield

摘要: 海拉尔油田由于储层埋藏深、地层应力分布不均匀及断层影响,水力压裂压力高,很容易造成砂堵,影响压裂改造效果,为此,采取了一系列压裂施工控制方法降低施工压力,并取得了良好效果。

Abstract: Due to deep reservoir burial depth , uneven distribution of formation stress and fault impact , as well as high hydraulic fracturing pressure , sand plug is easy to be caused which has a bad influence on fracturing effect.Therefore , a series of fracturing controlling methods have been adopted to reduce construction pressure.The application results indicate it has achieved good effect.
