摘要
本文以中扬子地区大地电磁资料为基础，综合其它地质地球物理资料，在大地电磁解释工作站上，采取人机对话的方式进行了资料的整理、处理和解释。其间运用了EMAP低通滤波和二维偏移技术等先进手段，并用地震、钻井等资料进行了必要的约束反演，使解释结果更加可信，地质效果大大提高。最后，得出该区燕山期以前的构造格架等重要结论，认为中扬子地区无论是中、新生界陆相地层还是中、古生界海相地层均具有良好的含油气远景。
Based on magnetotelluric (MT ) sites in central Yangzi area and other geophysical and geological data, the features of deep and regional geoelectric structures in the area are introduced in this paper. MT data are reprocessed by using MT interpretation workstation. Because the new effective methods of data processing, such as EMAP low filtering and MT migration techniques, the interpretation accuracy increase and the results are satisfied. From this, we determined Mesozoic framework of the area and boundaries of tectonic units etc.We think both the continental deposit of the Meso-Mesozoic and Cenozoic Era and the marine deposit of the Meso-Palaeozoic Era have good prospect for oil and gas.
