These affecting factors include density, extend, properties of faults and lithology. However, the effects from the properties of faults and lithology are concentrated on density of fault and fracture, so the information dimension is a measur-e ment for to w hat extent faults have developed. The distribution area of fracture was forecasted tw o relations:one is the rel-a tionship betw een information dimension of faults, the other is the relationship betw een the information dimension and density of fracture, three favorable fractur-e developed areas w ere sketched, w hich turned out to be in accordance w ith the distribu- tion of commercial w ells. Key words:fault;fracture;information dimension;affecting factors;favorable fractur-e developed area. 　　(fractal)“”, “ (, 1998), 20 80 ”(Mandelbort, 1982
