Abstract

In this paper, the commonly used pore structure models were summarized. The concept, construction method, and application of pore structure reconstruction model, pore network model, and equivalent pore network model were introduced. From pore structure reconstruction model to pore network model and then to equivalent pore network model, the description of pore structure develops from authenticity to equivalence, and the computational efficiency is significantly improved. A large number of studies have been carried out on seepage process on the basis of the pore structure model. Previous research shows that the pore structure model can reflect the influence of the pore structure of porous media on seepage process, and reveal the pore-scale mechanism of seepage and mass transfer process. The pore structure model has a good application prospect in many fields such as geo-environmental engineering and energy geotechnics. The future study about the pore structure model lies on the establishment of macro/microbehavior relationship according to pore structure model simulation and more universal model based on the equivalence of statistical parameters.
