摘要
首先介绍了描述动电现象的Stern 双电层模型,接着由一般通量—力关系导出了动电效应的声电耦合关系,然后用实际地层资料计算了动态耦合系数,分析了耦合系数与频率和地层参数的相关关系。最后发现,动电效应可用于解决强水淹油层的识别问题。
Describes the Stern double electric planes (i.e.inside Helmholtz plane and outside Helmholtz plane)model with electrokinetic phenomena;Derives the coupled electromagnetics and acoustics of electrokinetic effect from the relation between flux and force;Calculates dynamic coupling factor with the real formation data;Analyses the correlationship between the coupling factor and frequency as well as formation parameters;And finally,it is found that electrokinetic effect can be used identify heavily water flooded zone.
