| 摘 要： | 本文论述了三维电磁阵列剖面法的基本原理，并从理论上论述了大地电磁测深中的静态效应是由电磁响应中与频率无关的静态项引起的，基于这一原理，本文提出了三维ＥＭＡＰ野外采集方式和数据处理方程。三维ＥＭＡＰ法不仅能消除ＭＴ中的静态效应，而且由于采集信息量大大增加，较常规ＭＴ有更好的地质效果，文中给出的实例证明了这一点。

| Abstract: | In the present papcr,we discuss the principle of 3-D Elcctromagnetic Array Profiling (3-D EMAP) and dcmonstratc thcorctically that static offccf in magnctotclluric (MT) is caused by the static component which is indepondent on frequency. Bascd on this principle,we design the data acquistion and data processing methods.The 3-D EMAP can not only eliminiate the static offect, but also increase the acquired data message. So its geologieal effection would be better than MT, just on the gield example in this poper. |
