Stochastic modeling technology of reservoirs has been broadly applied in clastic reservoirs while scarcely applied in carbonate reservoirs. The heterogeneity in carbonate rocks more severe than that in clastic rocks leads to more tough problems for geological modeling precisely. Taking into account of the difficulties such as extensive area to be modeled, insufficient drilling information, incomplete seismic interpretation data, lack of facies controlling constraints and sophisticated gas-water contact, a solution is proposed in this paper in which the inversed information of reservoir thickness is used as plane constraints during attribute simulation, two gas fields are constrained by different correlation coefficients and precise geological models have been set up finally through reserve calculation by use of variable gas-water contact, obtaining good results and providing a reference for this type of geological modeling.
