野外CSAMT大多采集的是二维剖面数据,如何利用这些二维剖面数据获得尽可能接近实际情况的地电断面是许多电磁学者关心的问题。在对电磁正反演充分调研的基础上,可以对二维CSAMT剖面数据进行三维模型的模拟反演,通过三维数值模拟解决人工场源的三维特征问题,保证对三维地质体的模拟,同时拟合二维剖面数据,减小野外施工难度。在充分调研的基础上,系统地介绍了电磁正反演的研究现状及发展方向,讨论了用三维模型拟合二维剖面数据反演的可行性。
Most CSAMTs collected in the field are two-dimensional profile data. How to use these two-dimensional profile data to obtain the geoelectric profile as close to the actual situation as possible is a concern of many electromagnetists. Based on the full investigation of electromagnetic forward and inverse electromagnetic field, the 3D CSAMT profile data can be simulated and reconstructed by three-dimensional model. The three-dimensional numerical simulation can be used to solve the three-dimensional feature problem of the artificial field source to ensure the simulation of 3D geological body. Simultaneously, Combined two-dimensional profile data, reduce the difficulty of field construction. On the basis of full investigation and research, this paper systematically introduces the research status and development direction of forward and backward electromagnetic induction, and discusses the feasibility of fitting the two-dimensional cross-section data with 3D model.
