高频电磁测深法是一种利用天然高频电磁场作为场源的电磁勘探方法,具有高分辨率和相对直流电法较深的勘探深度的特点,特别适合中浅层地热和地下水勘探。本文介绍了一个应用高频电磁测深评价地下热水资源的一个成功实例。野外数据采集采用了高频电磁测深系统MT-U5A,采用远参考技术,以保证数据采集质量。高频电磁测深资料二维反演成像处理结果较好地描述了地下热水的空间分布范围,为查明该区的地下热水的来源提供了较有利的证据。
High-frequency electromagnetic sounding method is a kind of electromagnetic prospecting method using natural high-frequency electromagnetic field as the field source. It has the characteristics of deep exploration depth with high resolution and relative direct current method, and is especially suitable for medium-shallow geothermal and groundwater exploration. This article presents a successful example of using HF electromagnetic sounding to evaluate geothermal water resources. Field data acquisition using high-frequency electromagnetic sounding system MT-U5A, using far reference technology to ensure data acquisition quality. The result of 2-D inversion imaging of high-frequency electromagnetic sounding data can well describe the spatial distribution of underground hot water and provide more favorable evidence for identifying the source of underground hot water in this area.
