摘　　要：地热能作为一种新型清洁能源以其用途广、清洁低碳、可再生及开采成本低廉等特点,逐渐成为各国能源开发利用的重点,作为地热资源勘探的重要手段,物探方法以其精准度高、投入成本低备受青睐,然而单一的物探方法所得结果具有多解性。为提高物探结果的精确度,采用多种物探方法相结合的方式能使所得成果更加可靠。以云南省保山盆地金鸡片区地热资源勘查为例,采用直流垂向电测深与EH-4电磁测深相结合的综合物探方法,查明了该地区构造分布情况及地热异常区范围,为类似地热勘查工作提供参考。Geothermal energy,as a new type of clean energy,has gradually become the focus of energy development and utilization in various countries due to its wide application,clean and low carbon,renewable and low cost of exploitation.As an important means of geothermal resource exploration,the physical exploration method is highly favored for its high accuracy and low investment cost,however,the results obtained by a single physical exploration method are multi-deterministic.In order to improve the accuracy of physical exploration results,the combination of multiple physical exploration methods can make the results more reliable.Taking the geothermal resources exploration in Jinji Area of Baoshan Basin,Yunnan Province as an example,the comprehensive physical exploration method combining DC vertical electric bathymetry and EH-4 electromagnetic bathymetry is used to identify the tectonic distribution and the range of geothermal anomalies in the area,which provides a reference for similar geothermal exploration work.
