可控源大地电磁测深方法在河北三河市东部山区水文地质调查中的应用

Application of controlled source audio-frequency magnetotelluric sounding method in hydrogeological survey of eastern mountainou area of Sanhe city,Hebei

随着三河市东部山区近年来的快速发展,对水资源的需求也日益增加,良好的物探勘查方法是解决日益严峻的水资源需求的关键。我们应用对中深部勘查效果较好的方法可控源大地电磁测深法对该地区进行地下水勘查研究。通过研究地质资料、布置测线、数据采集、数据处理、数据反演分以及钻探、对比验证最终得出该地区的地下水的赋存位置及空间展布,从而验证可控源音频大地电磁测深法在三河市东部山区水文地质勘查中良好的应用效果。

With the rapid development of eastern mountainous area of S anhe city in recent years,demand for water resources is also increasing day by day. A good geophysical prospecting method is the key to solve the increasingly severe demand for water resources. For this reason,in this area we have conducted hydrogeological survey by using magnetotelluric sounding of method controlled source which possesses good effect for middle to deep exploration of groundwater. By studying geological data,arrangement of line,data acquisition,data processing,data inversion points,and through validation of drilling and contrast,we obtain groundwater occurrence location and spatial distribution in this area. This achievement demonstrates good application effect of the controlled source audio-frequency magnetotelluric sounding method on mountain hydrology geology exploration in eastern Sanhe.
