A Study of the Effect of Pore Characteristic on Permeability With a Pore Network Model

Porosity represents amount of pore, but the distribution of these pores is more important to percolation. The authors get core images from a computed tomography experiment of real rock core and use multiple point geological statistics to simulate 12 samples of digital core. Then they propose a new reconstruction method of pore network model and calculate the distribution of radius of pore body and pore throat. The authors study the relationship between model parameters and permeability. From the experiment they discover the number of throat whose width is more than 20 m is the main factor of the permeability.
