According to the relationship between faults and structural fractures

this paper processed fault system with fractal geometry

and set up the relationship of dimension value with fracture density in combination with log interpretation

performed fractal statistics of faults on top of the dolomite interval in the Kumugeliemu Group (Paleogene)

and the second and third lithologic intervals of the Bashijiqike Formation (Lower Cretaceous)

built relationship between fractural dimension values of faults at well point and the fracture density

and predicted interwell fracture distribution.The fractal dimension value of faults increases with fault density and length increase.Statistical values of fractal dimension of faults at well point show positive correlation with the linear density of fractures obtained by well logging interpretation.Fracture growth is significantly influenced by the geom- etry of anticlines.Fractures are commonly well developed in areas close to the axis of anticline and having a fractal dimension value over 1.25.The fracture density of three reservoir intervals near the A3 well is relatively large.Furthermore

some of the fractures may penetrate through the barriers

causing the watering of gas well.The study indicates that quantitative evaluation of fractures by using fractal geometry can guide exploration and development planning

and can be used to evaluate fractured reservoirs in oil/gas fields.
