【摘要】 本文指出 ,储层岩石表面粗糙、非均质性及高的能量 ,使我们难以用接触角来量度它的润湿性质。由于储层岩石孔隙结构不符合毛管束模型 ,使得 L aplace公式仅在表现接触角趋近于 0°或 180°时可用于根据毛管压力曲线计算储层岩石的孔径分布。好在由于储层岩石表面粗糙使我们常常会遇到这一极端情况。更多还原

【Abstract】 In this paper ,it is showed that the surfaceness,surface heterogeneity and high surface energy make it difficult to measure the wettability with the contact angle . Since the pore structure of porous media is not observed capillary tube model.Laplace equation can be used to calculate the pore size distribution of the reservoir rock based on the capillary pressure curve only when the apparent contact angle approaches to 0°or 180°.These extreme situations occur frequently due to the reservoir rock surface roughness.更多还原
