Reservoir fracture characteristics and its relationship with water injection development of Fuyu oilfield

At present,Fuyu oilfield has entered the late development stage of high water cut stage and the fracture development and distribution has directly affected water injection development effect.Based on core observation,analysis,fracture characteristics,through dynamic monitoring methods such as the well-to-well tracer test and inter-well testing by electric potential,by application of artificial and natural cracks coupling relationship,the reservoir fracture characteristics analysis have been analyzed.The artificial fracture trend has been predicted and it can provide guidance for the well pattern deployment.
