储层随机建模方法在细分沉积相中的应用

以SN油田S109井区油藏为研究对象，在储层构造、沉积微相、测井解释、储层非均质等研 究基础上，建立地质数据库，应用三维可视化技术对油藏构造、沉积微相和油藏属性建立三 维模型，通过建立的储层三维模型，对沉积微相划分等地质工作进行了检验和修改，从而建 立起符合研究区的沉积微相及储层物性分布，为后续油藏数值模拟工作打下基础。

APPLICATION OF THE RESERVOIR STOCHASTIC MODELING IN SUBDIVIDING SEDMENTARY FACIES

This paper introduces a 3D geological modeling technology of checking out and guiding geologic works. The technology can guarantee the middle and late stage development of oilfields, and can enhance the accuracy of the reservoir geological modeling. Based on the study of reservoir structures, sedimentary microfacies, interpretation of logging data, and reservoir heterogeneity, a 3D visualized geological model of the S109 section of SN Oilfield is established using the technology of 3D visualized geological modeling and the geologic database. The result is used in the reservoir precise digital modeling and in examining or amending the foundational work such as the sedimentary facies. The technology improves the precision of reservoir characterization and shortens the study period.
