Abstract

Spontaneous imbibition plays an important role in many practical processes, such as oil recovery, hydrology, and environmental engineering. The development in spontaneous imbibition goes fast in the past few years. In this paper, we focus on boundary conditions of spontaneous imbibition, which has important effects on spontaneous imbibition rate and efficiency. We introduce the fundamental physical mechanism of spontaneous imbibition with different boundary conditions by capillary model. Then, the studies of spontaneous imbibition in core scale are reviewed. The feature of spontaneous imbibition with different boundary conditions is discussed and the relative permeability for co- and counter-current imbibition is analyzed. The scaling of imbibition data with different boundary condition is also discussed by combination of experimental and numerical methods. At last, the analytical model of spontaneous imbibition is discussed. Cited as : Meng, Q., Cai, J. Recent advances in spontaneous imbibition with different boundary conditions.

不同边界条件下的自发渗吸研究进展

自发渗吸在采油、水文、环境工程等诸多实际过程中发挥着重要作用。近年来，自然渗吸技术发展较快。本文重点研究了对渗吸速率和效率有重要影响的渗吸边界条件。本文用毛细管模型介绍了不同边界条件下自发渗吸的基本物理机制。然后，对岩心尺度下的自发渗吸研究进行了综述。讨论了不同边界条件下的自发渗吸特性，分析了共渗和逆流渗吸的相对渗透率。采用实验与数值相结合的方法，讨论了不同边界条件下渗吸数据的标度问题。最后讨论了自发渗吸的解析模型。引用本文:孟强，蔡俊。不同边界条件下的自然渗吸研究进展。毛细管学，2018,1(3):19-26,doi: 10.26804/capi.2018.03.01
