Abstract: The minimum oil-bearing throat radius r_hmin and storage index β proposed by the author in the preceding paper [1] were used in calculation of 75 oil reservoirs in Liaohe,Changqing and Shengli oil fields. The results calculated are presented and the application of r_hmin and β to reservoir evaluation is discussed in this paper,including;1) classification of oil reservoirs in terms of the storage index,2) study of oil-water distribution and determination of initial oil saturation with r_hmin and capillary pressure curves and 3) calculation of oil column height in the oil reservoir according to r_hmin determined by initial oil saturation. The results obtained show that the storage index is closely related to the initial saturation of oil and,therefore,it can serve as a criterion of classification of oil reservoir. The initial saturation determined by r_hmin is more accurate than that obtained by the routine method using capillary pressure curves,because the hydrodynamic condition has been considered in the r_hmin calculation. With the introduction of r_hmin,it is possible to apply the Berg equation for oil column calculation to any type of traps simply by substituting r_hmin for the maximum throat radius of the boundary bed.
