Abstract: Based on the model of 3D porous medium, the fracture as a very important permeability channel is taken into account in the theoretical research on percolation of medium, the research methods of percolation in 3D porous and fractured double-medium is put forward, and the percolation model of 3D porous and fractured double-medium are established. The model applies to more fields, such as coal bed, rock mass. Based on VC++6.0, the software of 3D is developed, the percolation and the percolation law of 3D porous and fractured double-medium are simulated. The results indicate that fracture in the model increases the value of percolation probability observably. It makes the percolation law of double-medium differ from the law of porous medium. The natural phenomena of percolation transition happens surely with the increase in porosity, fracture fractal dimension and fracture number distribution initial value.

Key words: percolation, pore, fracture, fractal, percolation threshold, double-medium
