基于Maxwell 3D瞬变电磁法三维正演研究
Research about 3D Forward Modeling of Transient Electromagnetic Method Based on Maxwell 3D
摘要
Abstract
Transient electromagnetic method (TEM) is a very valuable way in the time domain electromagnetic methods which is used widely in geophysical electromagnetic field. At present, there are many problems with speed and precision about 3D inversion, which needs 3D forward analysis providing support. Though, there is very little software based on 3D forward modeling in domestic used for TEM. This article model forward methods based on Ansoft Maxwell 3D, used in the TEM forward modeling analysis. Compared with the traditional electromagnetic model analysis software-EMMA, it is not only proved to be feasibility in even half space model ,but also to build a low resistance globe model, simulation analysis model, and the simulation results can well reflect the existence of the underground anomalyglobe. The research process proved that Ansoft Maxwell 3D can be a very good used in modeling and analyzing TEM forward method, contenting the guidance demand of inversion method.关键词
