摘 要：1 Introduction The coal, as a special reservoir, has a dual accumulating system of matrix pore and fracture. The pore is the main reservoir space of coalbed methane （CBM） in coal. Generally, pore structure is very complicated and irregularly so that it is hard to be described in the traditional geometry. The fractal theory plays an important role in describing the porous media of the seepage system in recent years. The studies by Pfeifer, Katz and Kroch show the pore distribution in such reservoirs as coal, sandstone, shale and carbonatite is according with the fractal theory.
