Study on the Relationship between Fault System and Oil-Gas Sedimentary in Junggar Basin Based on GIS

There is a good correlation fractal value of high complexity and fault systems. Generally have higher value, fault systems of fractal dimension in fracture length, smaller, branch, tectonic deformation and fracture large extent. Otherwise, the fault systems have lower fractal dimension. Through the different methods of fractal dimension is different, have different meaning in the same place. In this paper, we calculate the fractal dimension of three types of the box counting dimension, information density and cumulative long one-dimensional functions of geographical information system (GIS), at the end of the use of weights those model to calculate the correlation coefficients between the hydrocarbon accumulation of three types of fractal dimension, to the importance of quality, fault systems.
