Fractal Dimensions of Faul t Systems and Theirn Hints to Migration Conditions of Gas from Deep Source Rocks

Abstract: Based upon the theory of fractal geometry,fractal dimensions of fault systems in the area east to theDaqing placanticline, Songliao Basin,were calculated using the box-counting approach to the reflecting T2T3and T4horizon and the studied area was divided into eight zones with different oil and gas distribution fea-tures. From the analysis of fractal behaviours on different sub一systems of faults in the studied area,it wasfound that the zone with high fault fractal dimensions is in good correspondence with the distribution of gasaccumulation from deep source rocks. This suggested that faults are main paths for gas migration from deepsource rocks. It was also concluded that the fratcal dimension of an fault system is an important parameter toquantitatively characterize the nature of migration and distribution of gas from deep source rocks.
