Low Permeable And Low Yield Reservoir System Study Of Perforation And Water Injection

Yanchang petroleum corporation zibei oil field locate the middle part of Ordos basin,belong to AnSai Delta plain doposit. As to exploited and exploiting Triassic system upper yanchang group were low permeable,low yield,low pressure and low porosity shallow underground reservoir,the physical property and recovery factor were unsatisfactory. In order to discovery a high efficiency way to exploite this reservoir,according to industrial standards,formulate oilfield exploite scheme before exploited.This thesis analysis and research zibei oil field, propose exploite scheme of perforation and water injection in similar reservoir.And to purpose of perforation and this reservoir, design and compare perforator、the condition of perforation (perforating fluid and the methods of perforation)、parameters of perforation; To water injection, design suitable pipe column、methods of water injection、processes of water injection、requirement of water injection, propose exploite scheme of water injection.The scheme were adaptable, operable and propagable, increase these similar reservoir development benefit and effect.
