Abstract

There are a lot of fractures in the fault zone, but it is difficult to simulate the 3D fracture zone. In this paper, a 3D simulation method of fracture zone based on fractal theory is presented. Considering the self-similarity of cracks, the fractal dimension is obtained by processing the pictures, which is obtained from the similarity simulation material experiment, while the maximum fracture length and opening of related fault zones are predicted. Then the approximate height range of the fracture zone is calculated by the empirical formula, and a fracture-based model under wire-frame is designed to simulate the fracture combined with fracture-related parameters. The experiment results show that the maximum crack parameters obtained by the prediction algorithm of crack parameters are less error than those obtained by similar simulation material tests, and the 3D model of fracture zone has a more realistic simulation effect, which provides a feasible method for 3D simulation of fracture distribution in the overburden fracture zone.
