     Planar heterogeneity of low-permeability fractured oil reservoir is much stronger, the conventional equi- librium initialization method can＇t be applied to characterize the heterogeneous distribution by the saturation inter- preted by well loggings in the numerical simulation. The initializing method by the initial saturation scaled by the capillary pressure not only has the advantage in high-speed computation and good convergence of the common equi- librium initialization, but takes advantage of the logging-interpreted oil saturation. The practice shows that the method can really describe the heterogeneity of the reservoirs, improve the efficiency and precision of the water-cut history matching. The method can quantitatively evaluate the qualities of the history matching, thus the much better foundations have been laid for the remained oil studies, program optimization and the indices prediction.
