提高电磁法信号采集质量和勘探效果方法的讨论

Discussion on improving the quality and effectiveness of electromagnetic method signal acquisition

全空域效应影响着电磁法野外采集信号质量和勘探效果,抑制或消除全空域效应愈来愈必要。本文给出了全空域效应概念、抑制或消除全空域效应原理,提出全空域效应影响采集信号质量和勘探效果机理,探讨电磁法中全空域效应及来源,抑制或消除思路、方法。

The whole airspace effect affects the quality of signal acquisition and the exploration effect in the field of electromagnetic method,and restraining or eliminating all airspace effect is more and more necessary.In this paper,the concept of full space effect,the principle of eliminating or eliminating the full space effect are given.The effect of the whole space effect on the quality of the acquisition signal and the mechanism of the exploration effect is put forward.The whole space effect and source in the electromagnetic method are discussed,and the ideas and methods are suppressed or eliminated.
