AB: In this study, we have developed a new method of generating a pore-network model for representing a porous medium. The method is based on the standard cubic lattice network and thus it has two elements: pore bodies located at the lattice points and pore throats connecting the pore bodies. One of the main features of our network is that pore throats can be oriented in 13 different directions. As a result, the coordination number of pore bodies may vary from 0 to 26, with a pre-specified average value for the whole network. We have applied this method to reconstruct a real sandstone utilizing information on coordination number distribution. Various network properties, such as number of pore bodies and pore throats, average coordination number, and coordination number distribution agree very well with observation data. This method can be especially useful in studying the effect of structure and coordination number distribution of pore-network models of solute transport and multiphase flow in porous media systems.
