Document Type and Number:
WIPO Patent Application WO/2023/224147
Kind Code:
A1
Abstract:
The present invention provides a method for predicting permeability according to the geometrical change in a porous medium on the basis of an apparent effective diameter, wherein the permeability according to a geometrical change in the porous medium can be precisely predicted. The method for predicting permeability according to geometric change in porous medium comprises the steps of: providing a porous medium; obtaining first porosity and first permeability at a plurality of points of the porous medium, respectively; calculating a first apparent effective diameter by using the first porosity and the first permeability; establishing a first correlation between the first porosity and the first apparent effective diameter, a second correlation between the first permeability and the first apparent 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.
