| 摘 要： | 为了认识低渗低饱和砂岩油藏的水驱油特征,在不同初始含油饱和度条件下,进行了两类水驱油物理模拟实验,得出含水率随注入孔隙体积倍数变化规律的关系曲线,并结合油藏模型的孔隙结构特征和油水分布状态分析了含水率变化的机理.采用Matlab软件拟合了复杂含水率变化曲线的一般经验公式,分析了公式中各系数对含水率曲线变化特征的影响,以... |

| Abstract: | Two types of physical simulation experiments of water displacing oil with different initial oil saturation are carried out in order to study the characteristics of water flooding in low-permeability and low-oil-saturation sandstone reservoir.The water-cut variation law with injected pore volume multiple is obtained,and the mechanism of the water-cut variation is analyzed according to both pore structure and oil-water distribution of the reservoir.A general empirical formula for the water-cut variation curve... |
