Application of Multi Subject Reservoir Studies in Oilfield Devlopment

It is more and more difficult to adjust layer system and well group and select measuring well for oilfield having developed many years.AS remaining oil highly discrete after polymer expulsion,meanwhile oilfield having developed extra high containing water period so that Horizontal well has become significant measure to exploit remaining oil in thick reservoir.It has known that the remaining oil distributing rule in base of subdividing research sedimentary facies and application of integrated reservoir studies and established corresponding methods to exploit remaining oil.With 3D geological modeling research definite quantity describe the interlayer in channel sand allocation in space and established favorite follow-up water flooding corresponding methods to extract remaining oil.It also can extract remaining oil in coping of thick reservoir and establish horizontal well productive reservoir optimizing principle and track design method.All these methods have effectively improve oilfield exploitation effect.
