应用储层随机建模方法细分沉积相

为保证油田的中、后期开发效果,就要做好油藏地质工作中的细分沉积相研究。提出了细分沉积相研究的新方法,以油藏为研究对象,利用其储层构造、沉积特征、测井数据、储层非均质等研究资料,建立地质数据库,应用储层随机建模的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,并由此对该区域沉积微相划分等地质工作进行验证和修改,建立起符合本研究区储层性质的沉积微相和物性分布,为数值模拟奠定基础。

Application of the reservoir stochastic modeling in subdividing sedimentary facies

Subdivision of the sedimentary facies is very crucial in the intermediary and later stage of oilfield development. This article provides a new way to subdivide the sedimen- tary facies and takes oil reservoir as the research target. On the basis of the reservoir structure,sedimentary fea- tures,logging data and reservoir heterogeneous,geologic database has been established.By using the 3D visualized technology based on reservoir stochastic model,3D mod- els on hydrocarbon reservoir structure,sedimentary sub- facies and hydrocarbon attribution have been built up, which can be used to verify or modify the subdivision of sedimentary facies,and lays a foundation for numerical simulation.
