摘　　要：本文通过利用地温测量、重力、磁力、CSAMT、氡气测量、微动测深以及大地电场岩性探测等综合物探方法,开展了平谷地区的地热资源勘查工作,初步查明了平谷区的地热地质条件,圈定了具有地热开发潜力的远景区,评价了平谷区地热资源开发潜力,并在后北宫地热远景区进行了钻探验证。利用多种物探方法综合解释,避免了单一方法的片面性和物探的多解性,在地热勘查中取得了较好的效果,可为地热调查工作程度较低区域开展勘查工作提供有意义的借鉴。Based on the application of multiple geophysical prospecting methods（including the geothermal survey, gravity exploration, magnetic exploration, CSAMT, radon measurement, fretting sounding and geoelectric fi eld lithology detection）, the geothermal resource survey of the Pinggu District has been carried out. In this surveying work, geological setting for the geothermal resource of the Pinggu District has been investigated, target areas with exploring potential have been defi ned, exploring potential of the geothermal resource has been evaluated, and geothermal prospecting area in Houbeigong region has been verifi ed by drilling. Avoiding the one-sidedness of single-method and the multiplicity of the geophysical prospecting, the application of multiple geophysical prospecting methods obtains preferable effort in geothermal exploration and provides meaningful reference for the area with lower level of the geothermal survey work.
