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 existing forward and inversion methods of cross hole electromagnetic imaging and their virtues and defects are introduced emphatically. It is pointed out that the future development of the cross hole electromagnetic imaging technique will still focus on instrument, influence of metal casing and imaging methods, and that the multicomponent cross hole electromagnetic system will be ultimately used in detecting the anisotropic property of cross hole formation in order that the hydrocarbon reservoirs can be accurately described.
