The use of electrical signals induced by seismic waves to explore for earth resources has attracted the interest of many research groups around the world since the mid-1990's. While seismoelectric signals are dependent upon a variety of physical properties, it is their potential to give information on pore fluids and fluid flow permeability with the resolution of seismic methods that has motivated interest in their measurement for applications in hydrogeology and hydrocarbon exploration. The electrokinetic coupling mechanism that has received most attention arises from disturbance of the electrical double layer that lies at the interface between the fluid and solid phases in porous and fractured media.

自20世纪90年代中期S以来，利用地震波诱发的电信号探测地球资源引起了世界各地许多研究小组的兴趣。虽然地震电信号依赖于各种物理性质，但它们具有以地震方法的分辨率提供孔隙流体和流体渗透率信息的潜力，这激发了人们对其测量在水文地质和油气勘探中应用的兴趣。在多孔和裂隙介质中，最受关注的电动耦合机制是位于流体和固体相界面处的电双电层的扰动。
