摘要
近年来,音频大地电磁法和土壤氡气测试,在大深度地质及区域构造调查领域内取得了优异的勘探效果.该文介绍了应用音频大地电磁法和氡气测试法两种手段对川西某地热构造进行探测的实例,通过数据处理及解译,综合分析判断,查明了该岩浆岩地区地热分布情况,经钻探验证,成功开采出地热水.该实例表明,音频大地电磁法和氡气测试法,在地热勘察中具有较高的实用和推广价值.
Abstract
In recent years,audio-frequency magnetotelluric(AMT)method and soil radon testing have achieved excellent exploration results in the field of large-deepth geological and regional tectonic investi-gation.This paper introduces a comprehensive application of these two methods to detect a geothermal structure in western Sichuan Province.Through data processing and interpretation,comprehensive analy-sis and judegment,the geothermal distribution in the magmatic rock area is identified.After drilling veri-fication,geothermal water is successfully mined.Practice has shown that audio-frequency magnetotelluric method and radon testing method have high practical and popularization value in geothermal exploration.
