Review of fluid seepage simulation in rock fractal discrete fracture network system
摘要
Abstract
Methods for description of fractal characteristics of geometric topological parameters of a rock fracture network system, including the length, aperture, orientation, and location, are reviewed. Percolation characteristics in the rock fracture network system and the important role of CT scanning technology in analyzing the fractal characteristic of fractures are pointed out. Achievements in research on the connectivity of the fracture network system using the percolation theory, methods for generation of the rock fracture network system based on the Monte-Carlo method, and simulation of fluid seepage in a fractal discrete fracture network system are systematically introduced. It is concluded that a model of the rock fractal discrete fracture network system constructed based on fractal characteristics and percolation characteristics can reflect the real rock fracture structure and seepage mechanism in the fracture network system. However, there is no large-scale commercial software for numerical simulation of percolation at present. Construction of a numerical model for the fractal discrete fracture network system based on the percolation theory will become the major research focus.关键词
