摘　　要：为检验前苏联和美国提出的某些震电勘探方法的实用性，在大庆开展了震电勘探方法实验，包括直流电场对地震波的影响以及地震波与电磁波的相互激发。实验是通过自制的电场前置放大器和已有的商用仪器在野外进行的。实验发现，在１０Ａ直流电场环境下，地震叠前炮记录上反射同相轴连续性变好，接收到第一类震电效应所引起的伴随电场和转换电磁波，这对震电勘探在大庆的进一步应用具有重要意义。Seismo-electric coupling has potential application on exploring oil, gas and water.In order to clear the charactere of the effect, several tests on seismo-electric couplinghave been carried out successfully in Daqing Oilfield. The experiments show thatseismo-electric coupling takes place between DC electric field and seismic wave.Under 10A DC field circumstances, the continuity of prestack seismic events becomesbetter. Electric field signals companying the seismic wave due to the first typeseismo-electric effect on the surface are received. A horizontal electric field signalwith the same travel time characters as seismo-electric convened wave from 400mdepth is also observed.
