论文摘要
可以通过不同的来源生成自势信号，并且可以分解各种贡献。散布电位是由于地下的水通量引起的贡献，并且在水域和储层表征中特别感兴趣。能够使用流潜力数据估算多孔和断裂培养基中的水通量取决于我们对矿物溶液接口处电动耦合的理解，以及我们理解，模型和高档这种现象的能力。已经提出了两种主要方法来预测地质媒体中流媒体的潜在产生。这些方法之一是基于确定通过水流有效拖动介质中的多余电荷。在本章中，我们描述了如何通过考虑这种有效的多余电荷密度，如何定义，计算和升级来建模流势。我们提供了这种方法的理论基础的简短概述，并描述了对水饱和和部分饱和的土壤和破裂培养基的不同应用。
Self-potential signals can be generated by different sources and can be decomposed in various contributions. Streming potential is the contribution due to the water flux in the subsurface and is of particular interest in hydrogeophysics and reservoir characterization. Being able to estimate water fluxes in porous and fractured media using streaming potential data relies on our understanding of the electrokinetic coupling at the mineral-solution interface and our capacity to understand, model, and upscale this phenomenon. Two main approaches have been proposed to predict streaming potential generation in geological media. One of these approaches is based on determining the excess charge which is effectively dragged in the medium by water flow. In this chapter, we describe how to model the streaming potential by considering this effective excess charge density, how it can be defined, calculated and upscaled. We provide a short overview of the theoretical basis of this approach and we describe different applications to both water saturated and partially saturated soils and fractured media.
