不同润湿性砂岩孔隙度与含油饱和度的定量关系

Quantitive relationship between porosity and oil saturation of sandstones with different wettabilities

摘要: 通过实验的方法,测定了济阳坳陷、东濮坳陷及吐哈盆地1172个含油砂岩样品的润湿性、孔隙度以及最大含油饱和度。对这些数据的统计分析表明,不同润湿性砂岩孔隙度与最大含油饱和度大致存在线性定量关系。

Abstract: Wettability,porosity and maximum oil saturation of 1 172 sandstone samples from oilfields of Jiyang seg,Dongpu seg and Tuha basins are detemined by laboratory analysis. The data show that maximum oil saturation of sandstones is directly proportional to their porosity.
