Abstract: Based on the accurate recognition of fractures in well point of Kela?2 gas field, this paper established the relationship between the fractal dimension of fault and the fracture density, and predicted the fracture distribution between wells by the fractal dimension of fault. The study results indicate that (1) the fractures in this area are dominated by structural fracture, with most half?filled and high?angle ones, and the fracture aperture ranges fror 0.1 mm to 0.4 mm, and linear density from 0.142 n/m to 1.842 n/m; (2) the fractal dimension of fault in well point can be used to predict the degree of fracture development, for it is of positive correlation with linear density of fracture interpreted from well logging data; (3) the area with fractal dimension value bigger than 1.2 is favorable to the generation of fractures, and in area with that bigger than 1.25, fracture is most developed
