Petrel建模技术在埕岛油田开发调整方案中的应用

The study of geological modeling of fluvial reservoir of shoal oil field

以埕岛油田埕北11井区馆上段为研究对象,采用petrel软件建模技术,针对海上油田的特点,探讨了应用沉积微相模型控制储层物性参数模拟的方法。并总结了沉积相建模的方法、思路。同时,采用研究区实际统计变差函数,应用序贯指示的方法对储层物性参数进行了随机模拟,提出了海上类似油田应用沉积微相确定性建模与随机储层物性模拟相结合以提高整体建模精度的思路。形成了一套适合埕岛油田储层特征的三维地质建模技术,为开发调整方案的部署提供了地质基础。

In view of the characteristics of shoal oil field with big and uneven well space and few basic data, the Petrel software of geological modeling was used to build geological models of the upper of Ng reservoirs in Cbll areas of Chengdao oilfield, adopting and discussing the methods of using the microfacies model to control the reservoir property parameters simulation, and summing up the methods and ideas of the sedimentary facies modeling. The method of Sequential Indicator Simulation was adopted to make stochastic simulation of the reservoir property on the basis of the actual statistical Variogram function of the study areas. An effective method of combining microfacies determinative modeling with reservoir property stochastic simulation was put forward, which can improve the accuracy of reservoir geological model, and formed a three--dimensional geological modeling technology that can be applied to the meandering river reservoirs.
