Application of reservoir quantitative characterization techniques based on dynamic and static data in dynamic study of double-high oilfield

Aiming at residual oil potential research object of J oilfield during the middle and later development periods,the fine reservoir characterization was carried on.In order to reduce the uncertainty in the study of sedimentary facies,based on well data,seismic data and dynamic action,analysis of the sedimentary microfacies was made,and the characteristics of sedimentary microfacies distribution in single sand layer were determined.Through the object-based simulation method of sedimentary facies,the contact relationship between the various microfacies sandbodies was characterized,and on this basis 3D geological models were made.Based on the research of sedimentary microfacies,quantitative characterization method of sand body was proposed,and reservoir numerical simulation verified the feasibility of the method.
