双河油田储层渗流单元分析及应用

油田开发后期预测剩余油分布的精度主要取决于数值模拟模型是否反映了储层的非均质性．介绍了双河油田储层渗流单元分析方法、渗流单元分类、储层渗流单元制图等;研究了储层渗流单元分布特征,认为渗流单元分布极其复杂,各种类型渗流单元相间分布,渗流单元规模、形态表现出极强的非均质性．提出了数值模拟器网格应根据渗流单元分布特征来划分,以期获得较高精度的剩余油公布图．

An Analysis of the Reservoir Seepage Flow Units in Shuanghe Oilfield

Prediction accuracy of residual oil distribution in late development stage depends mainly on whether numerical models reflect reservoir heterogeneity. This paper presents the analytical methods, classification and mapping of the reservoir seepage now units in shuanghe oilfield and researches their distribution features. The distribution of the seepage flow units is very complex with different types of seepage flow units alternating with each other and strong heterogeneity existed in the distribution ranges and shapes. The numerical modeling grids could be divided according to the distribution features of the seepage flow units to develop highly accurate residual oil distribution maps.
