This experimental study is dedicated to the measurements of gas permeability under confinement and to preliminary characterizations of salt rock poromechanical behavior. Salt porosity and permeability under loading are recorded either with argon or hydrogen gas. Permeability measurements carried out with both gases led to similar values. Poromechanical effects occur but they are weak and strongly dependent on the level of confining pressure. Furthermore, triaxial tests have been used to investigate the evolution of permeability of damaged salt samples with time and confinement. These experimental characterizations are finally analysed in the context of gas storage applications.

盐岩气体传输特性及应力耦合效应的实验研究

该实验研究致力于限制条件下的气体渗透率测量和盐岩孔隙力学行为的初步表征。负载下的盐孔隙率和渗透率用氩气或氢气记录。用两种气体进行的渗透率测量得到相似的值。会出现多孔力学效应，但它们很弱，并且强烈依赖于围压水平。此外，三轴试验已被用于研究受损盐样品的渗透率随时间和限制的演变。这些实验特征最终在储气应用的背景下进行分析。
