| 摘 要： | 为了指导三塘湖油田头屯河组储层的开发,针对储层特征,选择渗透率、压实校正后的孔隙度及孔喉半径R353个参数进行聚类、判别分析,将头屯河组划分为4类流动单元,各流动单元与沉积微相具有很好的对应关系。水驱油实验中,A类流动单元,水呈活塞式推进,驱油效率高;B类呈树枝状推进,驱油效率中等;C、D类呈指状推进,驱油效率低。微观孔隙结构的差异是造成驱油效率差别的主要原因。C、D类流动单元在研究区分布面积广,残余油多,是剩余油富集区。

| Abstract: | To guide the development of Toutunhe Formation reservoir in Santanghu Oilfield, some parameters as permeability, porosity by compaction and pore throat radius R35 are clustered and analyzed aimed at the reservoir characteristics. The Toutunhe Formation reservoir is divided into four kinds of flow units. The result shows that there is a good responding relationship between each flow unit and sedimentary microfacies. Through the oil displacement experiment by water, we can see that Type A flow unit is putting... |
