| 摘 要： | 为了提高瞬变电磁测深法对地探测的垂向分辨能力，文中研究了磁偶源瞬变电磁法快速成像的方法.详细讨论了电磁波与地震波在介质中的传播规律,分析了磁偶源瞬变电磁场在远区的响应特性.根据磁偶源瞬变电磁场与反射地震波的传播规律的相似性，提出了TEM资料拟地震快速成像解释的思路.理论模型正、反演计算结果表明方法理论是可行的，野外实测资料处理结果进一步说明了该方法是有效的.

| Abstract: | In order to improve the vertical resolution of the transient electromagnetic method(TEM),we make a study of the interpretation system of TEM tomography.The law of propagation of electromagnetic wave and seismic wave in media and the response of TEM far-field are analyzed.According to the similarity between the propagation of magnetic dipole source TEM field and reflected-seismic wave,it is proposed to explain TEM data with the pseudo-seismic interpretation.The forward and inversion calculation results of theoretical model examples indicate that the theory is right.The processing results of field data demonstrate that this method is useful and practical. |
