摘　　要：油田进行开发调整需要进行油藏数值模拟研究,而数模的一个重要基础就是地质模型。在赵凹油田地质模型的研究过程中,首先从基础地质研究着手,通过取心井的研究共识别了11种岩石相类型及6种沉积微相,采用高分辨率层序地层学原理划分了7个短期基准面旋回。在详细地质研究基础上,以短期旋回为单位采用截断高斯模拟方法建立沉积微相三维模型,采用相控物性参数建模技术,利用顺序高斯模拟方法建立孔隙度、渗透率的三维模型。最后对模型进行了粗化处理,直接提供给油藏数模使用。The reservoir numerical simulation is based on a fine 3D reservoir model. We built a fine 3D reservoir model using stochastic modeling technique in order to provide reliable data for optimizing exploitation plans for Zhaoao oilfield. Firstly, we identified 11 kinds of lithofacies, 6 combination of lithofacies through rock core description, and 6 microfacies types,then used theories to identify 7 short term base level cycles. Based on the detailed research, we built the microfacies model using truncating gauss simulation method, then under the control of microfacies we built porosity and permeability 3D model using sequence gauss simulation method. Lastly, reservoir model is upscaled for reservoir numerical simulation.
