摘　　要：系统地介绍了国内外井间电磁成像技术的研究现状 ,包括成像系统的灵敏度分析和适用范围 ,成像方法的分辨率 ,野外现场研究和仪器装备研究 ,金属套管的影响。重点介绍了现有的井间电磁成像正反演方法及其优缺点。指出井间电磁成像的研究方向将围绕仪器研制、金属套管的影响及成像方法等方面进行 ,最终将采用多分量井间电磁系统探测井间地层的各项异性特征 。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.
