Coupled Processes in Inhomogeneous Geological Systems

岩石中的电耦合系数普遍存在 用于石油、天然气和矿产勘探。 实例包括 井下电阻率和自然电位测量， 以及地表地球物理自电位剖面。 根据微观岩石解释测量结果 需要详细了解离子的作用机理， 孔隙网络中的运输 地质不均匀性 膜的形成是由于紧密混合、沉淀 和矿物混合物的成岩作用，或以有机物的形式 页岩中的表面涂层如油母岩。 这些 不均匀性可显著改变膜的性质 的岩石。 没有进行系统的研究， 研究这种依赖性。 本项目的目标是 为了更好地了解电的本质， 化学动力学耦合在这些不均匀的系统。

The electrical coupling coefficients in rocks are widely used in oil, gas and mineral prospecting. Examples include downhole resistivity and spontaneous potential measurements as well as surface gophysical self-potential profiling. Interpretation of the measurements in terms of microscopic rock properties requires a detailed knowledge of the mechanisms of ion transport in pore networks. Inhomogeneities in geologic membranes can arise as a result of intimate mixing, sedimentation and diagenesis of mixtures of minerals or in the form of organic surface coatings such as kerogen in shales. These inhomogeneities may significantly alter the membrane properties of the rock. No systematic study has been undertaken to investigate this dependence. It is the objective of this project to obtain a better understanding of the nature of electro- chemical-kinetic coupling in these inhomogeneous systems.
