T hese aff ecting f acto rs include density, ex tend, pr operties of f aults and lit ho lo gy . Ho w ev er, the eff ects fro m t he pr operties of f aults and litholog y are co ncentrated o n density o f f ault and fracture, so the infor matio n dimensio n is a measur e ment for to w hat ex tent f aults have developed. T he dist ributio n area of fracture w as for ecasted tw o relatio ns : one is the rela t ionship betw een infor mation dimensio n of f aults, the other is the relatio nship betw een the infor mation dimensio n and density of fracture, three f avo rable fr act ur edeveloped ar eas w ere sketched , w hich tur n
