储层建模技术在羊二庄油田明馆储层油藏描述中的应用

Application of Reservoir Modeling in Description of Minghua and Guantao Reservoir in Yangerzhuang Oil Field

摘要: 羊二庄油田明馆储层均为河流相沉积，由于曲流河的侧向迁移和辫状河河道的多期叠加造成储层非均质性严重。目前进入高含水、高开发后期，剩余油分布比较复杂，第一次油藏描述中应用传统的确定性建模方法已经不能满足剩余油挖潜描述的需要。为了解决上述问题，采用了RMS相控建模软件，通过构造建模、沉积微相建模、储层物性建模建立羊二庄油田三维可视化相控地质模型，并实现了与数模软件的无缝接口。
>The Minghua and Guantao reservoir in Yangerzhuang oil field pertain to fluvial facies, so the lateral migra- tion of Meander River and the multi-period superposition of braided channel lead to the serious reservoir heterogeneity. It is the time of last period of high cut and high development at present, residual oil distribute more complicated. Tradi- tional deterministic modeling adopted in the first description of reservoir can’t meet the excavation of residual oil. In order to solve the problems mentioned above, RMS phase-control modeling software is adopted to establish the three- dimensional visible phase-control geographical model in Yangerzhuang oil field by setting up structural modelling, sedimentary microfacies modeling and reservoir property modeling, which has realized the seamless interface with nu- merical simulation software.
