The modeling of mercury porosimetry and the relative permeability of mercury in sandstones using percolation theory
Drainage-type penetration into a number of regular networks representing the pore space was simulated on the computer with the help of a modified-site percolation approach. All of the networks are composed of two topological entities: capillaries and nodes. The porosimetry curve of mercury in sandstones the ''nonconductive saturation'' curve of mercury in sandstones, the relative permeability curve of mercury in sandstones, and the relative permeability curve of oil in a sandpack were calculated. The physical basis of the calculations is a one-to-one correspondence between the probability of a capillary being ''open'' and the cumulative distribution function of capillary diameters. In the calculations, realistic capillary- and node-diameter distribution functions, pore shapes, and relationships between the volume and the diameter of a pore were assumed. The cubic and the tetrahedral networks yield results in good agreement with the experimental data.
