摘要： 近年来，瞬变电磁法发展极快，它在地球物理勘探方面受到了极大的青睐。瞬变电磁法相对于传统的直流电
勘探法具有较大的优势，包括灵敏度高、探测深度较深以及抗干扰性强等，这也使得瞬变电磁法被广泛应用于煤矿、油
田等领域。为了满足现代地球物理勘探的应用需求，应用瞬变电磁法时需要充分结合实际生产条件，尽可能地控制其分
辨率和精度。从瞬变电磁法的基本原理出发，探讨了其发展及应用，同时分析了它在工程物探领域的应用实况，侧面证
明了瞬变电磁法的科学性和可行性。

Abstract: In recent years, transient electromagnetic method (TEM) has developed very fast, which has received great favor in
geophysical exploration. Compared with the traditional DC electric exploration method, TEM has great advantages, including high
sensitivity, deep detection and strong anti-interference, which makes TEM widely used in coal mine, oil field and other fields. In
order to meet the application requirements of modern geophysical exploration, the resolution and precision of TEM should be
controlled as much as possible by combining the actual production conditions. Based on the basic principle of TEM, this paper
discussed the development and application of TEM, and analyzed its application in the field of engineering geophysical exploration,
which proves the science and feasibility of TEM.

Key words: transient electromagnetic method; geophysical exploration; data processing; geological structure
