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