渗透率是表征输运性质的重要参数（例如，G.传热和传质）。准确、快速地确定多孔介质的渗透率是油藏工程、地下水工程、复合材料模拟等领域的关键问题之一。自吸是一种基本的、普遍存在的自然现象，广泛存在于各种过程中。本文根据达西定律推导了自吸高度和自吸量与时间的关系，提出了一种利用自吸效应预测多孔介质有效渗透率的简单方法，包括人工和天然多孔介质渗透率的表达式。通过实验数据分析和验证了模型的有效性。
Permeability is an important parameter for characterizing the transport properties (e. g. heat and mass transfer) of porous media. It is one of the crucial issues that the permeability of porous media is exactly and quickly decided in many fields such as reservoir engineering, groundwater engineering and composite material modeling. Spontaneous imbibition is a fundamental and ubiquitous natural phenomenon extensively existing in a variety of processes. In this paper, the relationships between the height and weight of imbibition versus the time are derived based on Darcy's law, and a simple method for predicting effective permeability of porous media using spontaneous imbibition effect is proposed, including expressions for permeabilities of artificial and natural porous media. The validity of the proposed models is analysed and tested by experimental data.
