摘要
An acoustical method of determining the spherical, or vuggy, porosity in carbonate rock formations, as a function of shear modulus. Total porosity and shear modulus of the formation is measured. Then the intrinsic granular porosity, dry bulk modulus, and spherical porosity are calculated. The carbonate rock is modeled, consisting of a primary host medium composed of carbonate grains with intergranular porosity between them. The model is easily modified to account for the case of intercrystalline microporosity existing within the grains, in addition to the intergranular porosity between them.
