深部电磁感应研究可以提供地下几百千米直到核幔边界的电导率分布信息,是地球构造、演化以及动力学研究中一种非常重要的地球物理手段,一直以来都是国内外研究的热点.本文拟从深部电磁感应的基本理论、正演模拟、数据处理及反演等三个方面,介绍几十年来国内外学者的研究成果,总结目前深部电磁感应研究所遇到的困难,并对其未来的发展提出建议.本文旨在使读者了解深部电磁感应研究的现状以及未来的发展方向和热点,以期推动该技术在我国得到进一步的发展和应用.
Deep electromagnetic induction studies can provide information about the electrical conductivity distribution from the subterranean to the mantle and the mantle. It is a very important geophysical approach in the study of the earth’s structure, evolution and dynamics. It has always been a hot research topic at home and abroad. This article intends to introduce the research results of scholars at home and abroad over the past decades from three aspects: the basic theory of deep electromagnetic induction, forward modeling, data processing and inversion, and summarizes the difficulties encountered by the current research on deep electromagnetic induction The future development of the proposal.This paper aims to enable readers to understand the status of the deep electromagnetic induction and the future direction of development and hot spots in order to promote the technology in our country to be further development and application.
