摘　　要：采用可控源音频大地电磁法和广域电磁法在江苏省滨海县月亮湾进行地热资源勘查,对可控源音频大地电磁法数据进行近场和过渡场曲线辅助校正和反演约束,获得滨海港地下地热资源电性结构信息,同时采用微动探测方法获得地下几何结构信息。综合分析3种地球物理资料进行解释结果,获得研究区地热模型,确定异常位置,随后钻井深度2919 m,出水量2171 m^(3)/d,水温51℃,综合物探成果与地质及地热井资料高度吻合,说明运用综合物探方法进行地热勘查,提高了勘探结果的可靠性。This study explored the geothermal resources in Yueliangwan,Binhai County,Jiangsu Province using the controlled source audio-frequency magnetotellurics(CSAMT)method and the wide-field electromagnetic method.Through the auxiliary correction of near-field and transition-field curves,as well as the inversion based on the CSAMT data,this study obtained the electrical structure information of underground geothermal resources in the Binhai port.Meanwhile,this study acquired the information on the underground geometric structure using the microtremor exploration method.By comprehensively analyzing the interpretation results of three kinds of geophysical data,this study obtained the geothermal model of the study area and determined the locations of the anomalies.A geothermal well with a depth of 2919 m was drilled in the study area,obtaining water yield of 2171 m^(3)/d with a water temperature of 51℃.The high consistency between the results from the comprehensive geophysical exploration and the geological and geothermal well data indicates that the comprehensive geophysical exploration method can improve the reliability of geothermal exploration results.
