摘要： 油水相对渗透率曲线反映了油水两相在多孔介质中的流动规律, 而微观孔隙结构特征是影响相渗曲 线形态的重要因素。分析了孔隙结构特征参数对储层渗透率和相渗特征的影响, 发现大庆F油层的空气渗透率随 孔隙半径和分选系数的增大而增大, 随结构系数的增大而减小; 束缚水饱和度和等渗点饱和度随孔隙半径和分选系 数的增大而减小, 随结构系数的增大而增大; 水相端点渗透率随孔隙半径和分选系数的增大而增大, 随结构系数的 增大而减小。储层物性、 相渗特征参数与孔隙结构特征参数均为幂函数关系。

Abstract: Oilwater relative permeability curve reflects the law of oil and water flowing in the porous media, and the characteristics of pore structure are important factors which greatly influence the relative permeability curve.The effects of the pore structure characteristics on the permeability and the characteristics of relative permeability in F reservoir was analyzed. It is found that the absolute permeability increases with the radius of pores and sorting coefficient upgoing and decreases with the coefficient of pore structure upgoing .The irreducible water saturation and isotonic point saturation decrease with the pore radius and sorting coefficient increasing, and increase with the coefficient of pore structure increasing.The endpoint permeability of water phase increases with the pore radius and sorting coefficient upgoing, and decreases with the coefficient of pore structure upgoing. The parameters of permeability and relative permeability characteristics in this formation are in power function relationship with the micro pore structure characteristics.
