3D Simulation of Rock Fractures Distribution in Gaosong Field, Gejiu Ore District
Fracture networks often are hierarchical and always present some kinds of scaling invariance. To consider these special characteristics, a geomathematical method is proposed in this paper to simulate the fracture distribution. The method mainly consists of: simulation of location, direction, aperture, and fracture connectivity, just as the application in Gaosong Triassic dolomite. The fracture locations are simulated using SGS method; the fracture strikes are simulated using principle component analysis method and Ordinary Kriging method. From the result, simulated fracture distribution corresponds well to hydraulic conductivity map, real fracture zone, and spring water distribution.
