摘要：

Acoustic wave and electromagnetic wave signals were recorded in the model borehole on the condition of different salinity by using the weak signal detection technology for investigating the seismoelectric conversion effect and exploring its potential application in well logging. The characteristics of the electromagnetic wave were analyzed by comparing with the acoustic wave. The results show that the electromagnetic wave is the converted electromagnetic wave induced by the acoustic wave when it propagates along the borehole. We found that the converted electromagnetic wave has symmetrical two dominant frequency crests in the spectrum. Pseudo-Rayleigh wave induces the seismoelectric conversion and radiates the converted electromagnetic wave in the borehole.
