| 本文对深地资源勘查 5种电磁新方法进行了讨论。它们分别是极低频电磁法(WEM)、多通道瞬变电磁法(MTEM)、电性源短偏移瞬变电磁法(SOTEM)、广域电磁法和相关检测电磁法。前 3种电磁法的作者认为，可实现 10 km深度范围内金属矿和油气资源的有效探测。由于资源与勘查方法缺乏应有的针对性，笔者不能苟同。广域电磁法有创意，笔者在几何测深能力与频率测深的分辨率以及场区场量的认识作了一些补充。对相关检测在电性源电磁法应用中存在问题作了商榷，第二方案虽有很大进步，但频、时域转换还存在问题有待进一步弄清问题所在。笔者认为，深地资源的勘查，不应以深度为目标，必须解决方法分辨率才能有所奏效。基础理论研究和高新技术的引进势在必行。 |
| 英文摘要: |
| This paper discusses five new electromagnetic methods for deep ground resource exploration. They are very low frequency electromagnetic method (WEM), multi-channel transient electromagnetic method (MTEM), electrical source short excursion transient electromagnetic method (SOTEM), wide-area electromagnetic method and related detection electromagnetic method. The authors of the first three electromagnetic methods believe that the e.ective detection of metal ore and oil and gas resources within a depth of 10km can be achieved. Due to the lack of resources and prospecting methods that should be targeted, the author cannot agree. The wide-area electromagnetic method is creative, and the author has made some supplements in the geometric sounding capability, the resolution of frequency sounding, and the knowledge of the .eld volume. The problems of related detection in the application of electrical source electromagnetic method are discussed. Although the second scheme has made great progress, there are still problems in frequency and time domain conversion that need to be further clari.ed.The author believes that the exploration of deep ground resources should not take depth as the goal. The resolution of the method must be resolved to be e.ective. Basic theoretical research and the introduction of high-tech are imperative. |
