【摘要】 从电化学理论、薄膜效应以及浓差极化,解释了震电效应的基本原理.通过室内沙槽和岩芯标本实验,发现了震电信号,且在砂土上的震电信号比粘土上的大;含石油岩芯标本上的震电效应信号比含水岩芯标本上的强.通过室外实验,也已经测量到可信的震电效应信号,从而为石油测井继续研究提供了实验数据.更多还原

【Abstract】 The seismo-electric effect is interpreted based on electrochemistry theories,membrane effect and thickness difference polarization.In indoor sand trough and drill core experiments,the seismo-electric effect is observed.The signal of seismoelectric effect is stronger in sandy soil than in clay,and stronger in drill core saturated with oil than that with water.The seismo-electric effect is also observed in outdoor experiments.The work is a base for the deep research of this field in oil well log.更多还原
