FRACTAL NATURE OF VISCOUS FINGERING IN RANDOM SIERPINSKI CARPET

The visco us fingering(VF) in a random Sierpinski carpet with bond rad ii of the truncated Rayleigh distribution has been investigated by mea ns of successive over-relaxation techniques. A universal formulation o f fractal dimension for VF in fractal space has been introduced. The t opology and geometry of the porous media are found to have strong effe cts on displacement process. The fractal dimension D can be reasonably regarded as a useful parameter to evaluate the sweep efficiency and o il recovery.
