Abstract：In recent years,integrative geophysical techniques of gravity,magnetic survey and electric survey developed toward the direction of 3D high precision and high-resolution survey and integrative survey,the former is basis and the latter is objective,both aspects have both connection and difference.So far as 3D gravity and magnetic survey is concerned?the data acquisition ? topographic correction and 3D forward and inversion methods are gradually practical;in view of 3D electro-magnetic survey,the data acquisition and processing can be easily fulfilled technically and there is a set of more feasible methods now,the current main issue is that the 3D forward and inversion methods haven’t a more adaptive and rapid algorithm,meanwhile,the 3D visualization of electro-magnetic data is proposed to adapt the platform used for visualization of seismic data.When expounding the development of integrative geophysical techniques of gravity,magnetic survey and electric survey,the paper emphasized the old integrative mode in the past that makes correlation and reference each other is no longer used,on the contrary,it must be a joint inversion based on 3D data,currently-studied joint inversion methods include constrained extrapolation method,anomaly-stripped method,sequential correction method and uniform correction method.
