Effect of Rock Nonhomogeneous Characteristics on Threshold Permeability
Permeability is one of an important characteristic of rock materials. The connectivity of permeate passageways could be used by probability of threshold permeability for evaluation. In the foundation of micro CT scan figures of rock samples, nonhomogeneous density distribution of inner rock is studied and connectivity rough of rock by threshold permeability program is also calculated. And the results are: the distribution of rock permeate passageways is nonhomogeneity and the probability of rock threshold permeability is also greatly declined, which is determined not only by ratios of nonporous particles but also by space distribution styles of porous medium.
