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。
In order to test the practicability of some seismic exploration methods proposed by the former Soviet Union and the United States, experiments on seismic exploration methods were conducted in Daqing, including the influence of DC electric field on seismic waves and the mutual excitation of seismic waves and electromagnetic waves. The experiment was conducted in the field through a homemade electric field pre-amplifier and existing commercial equipment. The experimental results show that under the condition of 10 A direct current electric field, the continuity of the reflection events of the prestack shots in seismicity becomes better, and the accompanying electric fields and converted electromagnetic waves caused by the first kind of electro- Application is of great importance.
