胜利油田高89地区滩坝砂油藏CO_2驱地质建模技术研究

Study on geological modeling technology of beach bar sand reservoir by CO_2 flooding in gao89 area of Shengli Oilfield

通过对常规地质建模软件深入开发,结合高89地区实际应用情况,从复杂断层处理、网格设计方法、滩坝砂储层砂体模型控制及相控属性模拟等关键环节进行了建模技术研究,总结出了适合滩坝砂油藏CO2驱的建模技术和方法。应用效果表明,这些方法的应用极大地提高了地质建模的效率及模型的精度和准确性,反映了油藏非均质性特点,为精细油藏数值模拟等后续油藏研究奠定了基础。

Through the further development of conventional geologic modeling software, and combined with the practical application of gao89 area, modeling technology are studied from complex fault processing, grid design method, beach bar sand sandbody model control and phase control attribute simulation such as the key link, summed up a suitable beach bar sand reservoir CO2flooding technology and modeling method. The application results show that, the application of these methods has greatly improved the accuracy and the efficiency and accuracy of model of geological modeling, reflecting the characteristics of reservoir heterogeneity, which lays a foundation for the fine reservoir numerical simulation and subsequent reservoir study.
