摘要: 采用地质约束的相控建模是提高储层建模精度的核心所在。以镇泾油田长6油层组为例,说明了这一研究的基本思路与步骤,包括等时地层格架的搭建与对比,沉积模式分析,随机模拟方法的优选与改进,定量地质知识库的建立以及储层三维随机建模。研究结果表明,与常规方法相比,这种建模思路,促进了地质沉积模式向三维建模的定量化应用,建模结果更符合地下地质体的实际情况。Abstract: Facies-controlled modeling with geological con- straint is the kernel of improving reservoir modeling accu- racy.Taking the oil set C6 in Zhenjing oilfield as an ex- ample,the basic principles and steps have been studied, which include building and comparison of isochromatic stratigraphic framework,sedimentary model analysis,op- timum selection and improvement of stochastic simulation method,the building of quantitative geological knowledge data base and 3-D stochastic modeling.Compared with conventional method,this way of modeling improves the quantitative application of 3D modeling and the results are more in accordance with underground geologic bodies.
