摘要: 多通道瞬变电磁法是近年来国际发展的油气资源探测新方法,为了实现这种方法由油气资源领域向矿产资源勘查领域的拓展,中国科学院地质与地球物理研究所牵头对其装备与数据处理解释系统开展技术攻关.针对上述自主研发的多通道瞬变电磁装置,基于其数据采集、数据处理与解释等技术要求,本文对与之匹配开发的多通道瞬变电法磁数据处理解释系统(包含预处理、大地响应正演模拟、二维和三维数据偏移成像等模块)的性能进行分析,结果表明:经过对多通道瞬变电磁法数据处理方法的技术攻关,形成了包含数据处理、正演模拟、二三维偏移成像、解释与可视化等模块的多通道瞬变电磁数据处理解释系统,为多通道大功率电法勘探系统的应用提供了良好的支撑作用.

Abstract: Multi-channel Transient Electromagnetic Method (M-TEM) is a new method for detecting oil and gas resources in recent years. In order to develop this method from the field of oil and gas resources to mineral resources exploration, the research of this method in equipment technology, data processing and interpretation system is carried out by the Institute of Geology and Geophysics, Chinese Academy of Sciences. In the form of data acquisition, data processing and interpretation,data preprocessing, forward simulation, and two-dimensional and three-dimensional data migration imaging are analyzed in this paper. The results show that the data processing technology of MTEM can support two or three dimensional migration imaging, interpretation and visualization. Also, it will provide a good support for the application of multi-channel and high-power electrical exploration system.
