Abstract: The reservoir heterogeneity of Liuhua 11-1 Oilfield was quantitatively characterized.On the basis of research on the internal,interlayer and plane heterogeneity of the oilfield,a new method for characterizing reservoir heterogeneity with integrative index of reservoir heterogeneity was introduced to overcome some defects in previous researches.This method is based on combination of three parameters including porosity,permeability and interlayer for describing reservoir quality and two parameters such as microfacies and faulting to describe geometric aspects of the reservoir.The remaining oil distribution can be predicted directly on clarifying the preferable connection between integrative index of reservoir heterogeneity and remaining oil saturation.On the basis of comprehensive analysis of dynamic and static data,some new sidetrack wells were programmed in the enrichment regions of the remaining oil.The application effects of this method in Liuhua 11-1 Oilfield are good and can be used in other similar oilfields.
