Abstract: The Earth Vision Software is generally accepted as adeveloping geologic model software in petroleum indus-try. Since introduction into Turpan-Hami oilfield in 1997, it has played an important part in petroleum exploration, particu-larly for prospecting subtle oil reservoirs. In numericalsimulation of oilfield exploration,the software canbe applied to de-velopfaulting model, structural model,reservoir rock model andfluid model,followed by the final petrolem reservoir modelthat is the most coincident with actual situations, providing proper and reliable geologic parameters field, increasing accura-cies of thesimulation and prediction, and improvingthe levels of comprehensive reservoir management.
