Development of adsorption ratio equation and state equation of liquid and their geological significance

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