煤储层固—液—气相间作用的等温吸附实验研究

在介绍体积法等温吸附实验原理的基础上，阐述了平衡水煤样等温吸附实验方法，重点探讨了煤的注水实验和注水煤样的等温吸附实验技术，讨论了等温吸附实验结果的信息提取和意义。研究表明：液态水对煤基质吸附气体有显著影响，作用机理与甲烷气体同时运动于气液界面和固气界面之间有关。

A Study on Isothermal Adsorption Experimental Methods Concerning Phase Interaction in Coal Reservoirs

The coal isothermal adsorption experiment and its gained parameters played an important role in resource assessment and development of coalbed methane.The theory and equipments of the isothermal sorption experiment of the volume method were introduced,the isothermal sorption experiments of dry and equilibrium water coals were described,the technique of the experiments of isothermal sorption of injection water coals and the injecting water of coals were emphasized and explored, and the information extraction and data disposal of results of the isothermal sorption experiments were discussed.By the above researches,the following conclusion was drawn that the liquid water affects coal matrix absorbing gases markedly, and the function mechanism relates to the fact that the methane moves between the gas-liquid interface and the solid-gas interface.
