Abstract
In the fracture network, the surfaces of fracture are frequently rough. In this article, a binary tree fractal model for curved capillaries has been established based on the fractal theory. The expression of the mass flux rate of the fluid in the rough fracture network has been derived following the Hagar-Poiseuille formula, and the term of the gas mass flux rate has been obtained by using the gas plane radial flow binomial law. The two have been combined to obtain a fracture network permeability model. The correctness and availability of the model have been demonstrated by comparing it with the experimental data. Furthermore, the sensitivity of the model parameters has been analyzed.
