Abstract

There have been many theories to describe adsorbed or free gas. However, quantitative description of the occurrence characteristics of liquids in porous media has always been a great challenge due to a lack of basic theory. Through years of research, two theoretical equations, i.e., adsorption ratio equation and state equation of liquid, have been proposed to describe the characteristics of liquids in porous media, and revealed the mechanism of liquid occurrence. Further, a quantitative evaluation technology for the microscopic distribution of liquids was established by combining nuclear magnetic resonance theory. This research will be of great signiﬁcance for studying the microscopic distribution of liquids in tight reservoirs, such as shale, coal, and tight sandstone. Cited as: Li, J.

液体吸附比方程和状态方程的发展及其地质意义

已经有许多理论来描述吸附气体或游离气体。然而，由于缺乏基础理论，对多孔介质中液体赋存特征的定量描述一直是一个巨大的挑战。通过多年的研究，提出了描述多孔介质中液体特性的吸附比方程和液体状态方程两个理论方程，揭示了液体的发生机理。结合核磁共振理论，建立了液体微观分布的定量评价技术。该研究对研究页岩、煤、致密砂岩等致密储层流体微观分布具有重要意义。李静。液体吸附比方程和状态方程的发展及其地质意义。毛细管学，2021,4(4):63-65,doi: 10.46690/capi.2021.04.01
