| 摘 要： | 电磁勘探技术是应用最早、应用最广的物探技术之一,也是与地震法最为接近的勘探技术。电磁勘探技术无论是发展规模还是技术水平与地震的差距还是很大。加快电磁勘探技术的发展和应用具有重要意义。通过对比两者的技术经济特征,分析电磁勘探技术在油气、深部矿产和水资源等六个领域的现状、潜力和机遇。进一步剖析了电磁勘探技术中电磁波场的固有局限性、岩石导电物理机理研究的不足,以及电磁勘探数据采集、处理解释技术的问题,同时指出了在这几个方面的发展方向。

| Abstract: | Electromagnetic exploration technology is one of the earliest and most widely used geophysical techniques,and it is also the closest exploration technology to seismic method.However,why is the gap between the development scale and technology level of electromagnetic exploration technology and earthquakes so large?It is of great significance to accelerate the development and application of electromagnetic exploration technology.By comparing the technical and economic characteristics of the two methods,this paper analyses the present situation,potential and opportunity of electromagnetic exploration technology in six fields,including oil and gas,deep mineral resources and water resources,further analyses the inherent limitations of electromagnetic wave field in electromagnetic exploration technology,the insufficiency of the study of rock conductivity physical mechanism,and the problems of data acquisition,processing and interpretation technology in electromagnetic exploration,and points out these problems.The development direction of this aspect. |
