Method for predicting permeability according to geometrical change in porous medium on basis of superficial effective diameter

Abstract

Provided a method for predicting permeability according to the geometrical change in a porous medium on the basis of a superficial effective diameter, wherein the permeability according to geometrical changes in the porous medium is precisely predicted. The method for predicting permeability according to geometric change in the porous medium comprises: providing a porous medium; obtaining first porosity and first permeability at a plurality of points of the porous medium, respectively; calculating a first superficial effective diameter using the first porosity and the first permeability; establishing a first correlation between the first porosity and the first superficial effective diameter, a second correlation between the first permeability and the first superficial effective diameter, and a third correlation between the first porosity and the first permeability; and using the correlations to predict a second permeability for a second porosity changed by a geometrical change in the porous medium.
