4. Discussion 4.1. Validation of the Permeability ModelThe steps to determine the parameters of Chen’s model are as follows: Cf was fitted by Equation (1) using the data from the elastic compression stage to obtain the best fitting result; after the Cf was determined, the parameters α, β, and γ were fitted according to Equation (3) to obtain the best fitting value. We obtained parameters E, K, φ0, l, etc.
