摘　　要：因为地热勘查目标体较深,埋藏浅的也要近千米,勘探难度大,单一的物探勘查方法所得结果认识模糊,很难获得好的效果。笔者设计一项地热勘查,在辽宁省某地热带上,投入了地面高精度磁测、CSAMT、TEM、使用EH-4做MT(fmin=0.1 Hz)、使用V8做MT等多种勘查方法。多种方法的投入既提供了多参数多信息,又相互验证了方法的有效性,从而对最终结果的判识起到了至关重要的作用,最终成功布井。说明了综合利用物探方法在勘探难度增大的工作中是解决问题的有效途径。Currently,increasing attention is paid to the green energy,and tourism has become a critical part of modem people＇s lives. In such a situation, geothermal exploration becomes more and more important in geophysical work because the targets of geothermal ex-ploration are relatively deep,and their burial depths are about 1 km,or even up to 3 km or deeper. The single geophysical method is commonly employed and,as a result,the understanding of result is unclear,and the geological interpretation is not effective. In this study,the authors carried out a geothermal survey,in ＂which the magnetic,CSAMT,TEM, MT/AMT （using EH-4 and V8 instru-ments） methods were employed. Multiple geophysical methods can supply multi-parameter information,and can cross-validate the ef-fectiveness of each method. The successful selection of drilling targets demonstrated that the employment of integrated geophysical meth-ods is an effective solution in challengeable exploration tasks.
