| 英文摘要: | A core-flooding technique to measure core- and subcore-scale capillary pressure curves is applied to the characterization of a naturally heterogeneous sandstone core. N2 and water are used as the nonwetting and wetting fluid phases, and X-ray imaging is applied to precisely visualize multiphase flow at the subcentimeter scale. The spatial variability in the Pc(S) relationship is represented in terms of scaling factors, which are further translated into a corresponding distribution of permeabilities, thus creating a unique and consistent framework where multiphase and rock properties are integrated. The analysis introduced here provides a practical and efficient method for characterizing subcore-scale heterogeneities, whose effects can be substantial on both single and multiphase flows. © 2013.
