摘要
近年来,可控源音频大地电磁法(CSAMT)在地热资源勘查中应用越来越多,在构造判定和地层划分方面具有独特的优势。介绍了CSAMT的方法原理,详细论述了江苏句容茅山地热资源勘查中V8多功能电法系统野外施工、数据采集、数据处理及最后的应用成果。茅山CSAMT成果与地质及地热井资料吻合较好,说明CSAMT法在地热资源勘查方面是一种行之有效的物探方法。该方法工作成本低、效率高,是当前地热勘查工作首选也是较为有效的方法。
Recently,the Controlled Source Audio-frequency Magnetotelluric( CSAMT) method is widely used in geothermal resource exploration,which is mostly owing to its advantage in structural identification and stratigraphic subdivision. While introducing the principle of CSAMT,this paper presents the field operation,data collection,data processing and final application result in geothermal exploration by using V8 Receiver in the geothermal resource exploration in Mount Maoshan of Jurong,Jiangsu Province. The result of CSAMT method in Mount Maoshan is consistent with the geological and geothermal wells information. Thus,it is concluded that the CSAMT is a cost-effective and highly efficient geophysical prospecting method in geothermal exploration.
