Table 4 Relationships of pore structure parameters with anisotropy and heterogeneity.

Pore structure parameter Anisotropy Heterogeneity ?eff ?eff slightly decrease as A increases Small in variation r Variation is small and uncorrelated Variation is small and uncorrelated τ τ decreases significantly as A increases Variation is obvious and uncorrelated S S slightly increases as A increases S decreases significantly as H increases d No variation and uncorrelated d increases as H increases (associated with S)
