Realization of sonically induced polarization (SIP) logging is based on studies of the borehole SIP effect. This effect is essentially transformation of acoustic waves into electromagnetic waves in two phase porous media, resulting in formation of borehole sonic electric transformation wave fields, and eventually behaves as transformation of acoustic radiation energy into electromagnetic energy. In this paper, through theoretical analysis of the energy components of the sonic electric transformation wave fields in two phase porous media, the overall energy composition of borehole sonic electric transformation wave fields is studied. A concept of electrical energy volumetric density of borehole low frequency SIP electrical field is proposed, and its expression is derived. Finally by modeling borehole low frequency SIP electrical fields with real formation parameter models, we have established the relationships between both acoustic frequencies and formation parameters, and electrical energy volumetric density in the borehole low frequency SIP processes.
