Stochastic modeling technique is increasingly becoming a significant trend in reservoir modeling. In this paper, a reviewing on the development of stochastic modeling was presented, and then, in order to emphasize the necessity of applying the technique in reservoir modeling, the stochastic character of reservoirs was discussed, and a comparasion of interpolation with simulation was made. Moreover, something was done on the classification of stochastic modeling methods, which are common in current literatures, on the basic principle, the advantage and draw backs of a few commonly used methods for modeling discrete models. After analysing the function of geological knowledge and other modeling techniques in the procedure of stochastic modeling, it was commented that stochastic modeling would be a prospective trend of reservoir modeling in the early period of reservoir development, but the key for the success of applying the technique for reservoir modeling would be how to integrate geological knowledge and other modeling techniques in stochastic modeling.
