摘　　要：1.Current status Three-dimensional(3D)inversion of geophysical EM data is generally underdetermined,non-linear,and of large-scale that is very difficult to solve by optimization.In the past two decades,with the advancement of computational equipment and numerical algorithms,3D geophysical EM inversion has made great progress.Numerous inversion codes and platforms based on the regularizations have been successfully developed and are being widely used in the industry and scientific research.The development of 3D EM inversions mainly involve the following aspects.
