... This proposal focusses on three topics: 1. Measurement of the permeability of relevant core samplex; its anisotropy and pressure dependence. The matrix permeabilities will be compared to borehole data. 2. The electrical parameters frequency dispersion of the electrical conductivity, streaming-, self- and zeta-potential provide information on the physical/chemical interactions between the rock matrix and the pore sturrand. They will be correlated with lithological parameters and borehole data and will be related to fluid mobilities. 3. Rheological properties of salt, recrystallisation and interactions with fluids will be studied under pressure/temperature conditions by means of energy dispersive x-ray diffraction. The loss of water and/or structural changes will thus be detectable.

...该提案侧重于三个主题：1。测量相关岩心样品的渗透率;其各向异性和压力依赖性。将基质渗透率与钻孔数据进行比较。2.电导率、流动电位、自电位和zeta电位的电参数频散提供了岩石基质与孔隙介质之间物理/化学相互作用的信息。它们将与岩性参数和钻孔数据相关，并与流体流动性相关。3.将通过能量色散X射线衍射在压力/温度条件下研究盐的流变特性、重结晶和与流体的相互作用。因此，水的损失和/或结构变化将是可检测的。
