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 the magnetotelluric data in the middle Yangtze region and based on other geophysical and geophysical data, the paper arranges, processes and interprets the data on the magnetotelluric interpretation workstation using man-machine dialogue. In the meantime, advanced methods such as EMAP low-pass filtering and two-dimensional migration are applied. The necessary constraint inversion is carried out by using seismic data and drilling data to make the interpretation credible and the geological effect greatly enhanced. Finally, we draw the important conclusions such as the tectonic framework before the Yanshanian period in this area, and hold that the mid-and-Cenozoic continental facies, Mesozoic and Paleozoic marine facies all have good hydrocarbon-bearing vista.
