摘要:

多孔介质自发渗吸现象普遍存在于自然界和工业应用领域, 深入研究其微观流动机理及宏观渗流规律具有重要的科学和工程价值。由于受多孔介质物理属性、流体性质、边界条件等多种因素的影响, 自发渗吸机理及渗流规律难以厘清。目前, 已有众多物理实验、理论分析及数值模拟等方法对多因素影响下的自发渗吸过程进行了广泛而深入的研究。本文就该领域存在的关键问题及最新进展进行梳理分析并提出若干思考, 以期对多孔介质自发渗吸的理解和未来研究工作提供一定的借鉴。

Abstract:

Spontaneous imbibition in porous media is ubiquitous in natural and industrial applications. It is of great value to probe into the microscopic and macroscopic multiphase flow mechanisms of spontaneous imbibition in science and engineering aspects. However, due to the multi-influencing factors such as petrophysical properties, fluid properties and boundary conditions in porous media, the microscopic and macroscopic flow mechanisms in spontaneous imbibition are difficult to be understood thoroughly. Currently, the spontaneous imbibition process under the influence of multiple factors is widely studied and mainly focused on laboratory experiments, theoretical analysis and numerical simulations. In this paper, the key issues and recent progress in spontaneous imbibition are analyzed, and some suggestions and an in-depth understanding of capillarity in porous media are provided for future work.

Key words: porous media, spontaneous imbibition, flow mechanism, seepage law
