Abstract
Provided a method of predicting permeability of porous material based on anisotropic flow model. The method of predicting permeability of porous material based on anisotropic flow model comprises: providing a porous medium; establishing a concentric annulus flow model for the porous medium; calculating a concentric annulus cylinder interstitial flow velocity, a concentric annulus cylinder hydraulic tortuosity, and a concentric annulus cylinder hydraulic diameter using the concentric annulus flow model; and predicting a permeability for the porous medium using the concentric annulus cylinder hydraulic tortuosity and the concentric annulus cylinder hydraulic diameter.
