|
Abstract:
频率域可控源电磁法(FCSEM)是一种基于人工源激发的地球物理勘探方法，比大地电磁探测有更强的扛干扰能力，比重磁勘探有更高的分辨率。因此在地球物理资源勘探领域中发挥着关键的作用。FCSEM反演方法的研究及其算法稳定性、有效性和计算效率，一直都是近年来的热点。本文主要介绍了可控源电磁法三维反演数值模拟技术，进展，以及相关解算法的应用，并对各种方法的特点作了比较分析，最后对FCSEM进行了总结，并给出了未来的发展方向。
Frequency domain controlled source electromagnetic (FCSEM), a geophysical exploration method, is based on artificial source excitation. The method is stronger in the interference carrying than electromagnetic exploration and is higher in resolution than gravity-magnetic prospecting. Recently, the theory research and effectiveness, stability, and computational efficiency of 3D CSEM inversion have always been the focus. This paper mainly introduces 3D CSEM inversion, including the progress of numerical simulation methods and the application of algorithms relating solution, compares the properties of various methods, and gives the prospect of future development. Finally, CSEM method is summarized, and the future development direction is given.
