摘　　要：井间电磁探测方法(Cross-hole Electromagnetic Method,CHEM)是近20年发展起来的一项新的储层监测和评价技术,它可以提供井间储层电阻率分布信息,进而实现流体空间分布的描述。该技术可用于识别由于储层非均质性等造成的死油区、监测储层的宏观波及系数、优化设计加密井位和提升油藏数值模拟的有效性。通过对近年国际学术会议及相关学术期刊关于井间电磁探测技术文献的追踪分析,介绍了井间电磁探测技术的基本原理、响应数值模拟、采集设计与处理解释技术和目前在油气储层监测中的应用状况及存在的问题,指出了井间电磁探测技术未来的发展与研究方向,以供国内电磁勘探业界及相关研究人员参考。Developed in recent years, the cross-hole electromagnetic method (CHEM) is one of the new technologies applied to hydrocarbon reservoir evaluation and monitoring. It can directly provide information of resistivity distribution of an inter-well area, and therefore it can provide fluid distribution mapping at the inter-well scale. It can be used for identifying bypassed hydrocarbon resulted from the heterogeneity, monitoring the macroscopic sweep efficiency, planning optimum infill drilling and improving effectiveness of reservoir simulation. Based on the analysis of the publications related to the cross-hole electromagnetic method, we review in this paper its fundamental principle, development history, the techniques of data acquisition, processing and interpretation. We also discuss the challenges in the present applications and the development trend in the future.
