The present situation of research on cross hole electromagnetic imaging technique at home and abroad is introduced systematically, including sensitivity analysis and scope of application of the imaging system, resolution of imaging methods, research on field operation and instrument, influence of metal casing.

The cross-well logging technique of measuring electric resistivity of stratum through metal casing has wide foreground, but it is still in the primary stage of investigation and exploiture.

Method for fine-description of reservoir based on cross-hole seismic data;

Application of cauchy-constraint blind deconvolution in cross-hole seismic data processing;

Numeric simulation of 3-Component cross-hole seismic surveying wavefield in VTI media;
