摘要： 根据吸附位势(位能)理论. 利用Dubinin吸附势的定义。对于同一种类型的吸附剂(多孔介质),对不同吸附质在不同温度条件下测得的吸附实验数据.将其吸附量和吸附势相关联_拟合得到相应的回归方程。并利 用拟合得到的回归方程,针对某个气藏(Case2).在确定的平均气层岩心参数的条件下，建立该气藏在给定气层温度下所有组分的吸附等温线。此项研究工作将为开展多孔介质中吸附作用的各种研究(如吸附平衡相态模拟和油气藏数值模拟研究等)提供重要的基础数据和研究方法，

Abstract: For the different adsorbates in the same adsorbent (porous media), the adsorption powers measured under the differenttemperatures are correlated with the adsorption potentials. The relative regression equations are given by matching the experimentaladsorption data from adsorption potential theory and definition of Dubinin adsorption potential. The regression equation can be usedto determine the average petrophysical parameters for a gas reservoir (Case 2)and create the adsorption isothermal curves forvarious components under given gas-layer temperature in it. It provides significant basic data and research methods such asadsorption phase equilibrium simulation and oil-gas reservoir numerical simulation for study of adsorption processes in porous media.

Key words: adsorption, isotherm, porous media, gas reservoir
