摘　　要：大地电磁勘探方法作为一种传统的频率域测深法,具有勘探深度大、不受低阻层屏蔽、施工效率高等优势,在地热调查中应用广泛。以新疆温泉县博尔塔拉河谷地地区地热资源成藏模式为研究对象,利用大地电磁测深与可控源音频大地电磁两种勘探数据,反演计算出岩层电阻率信息,结合地质测深、地震构造解译等结果相互印证,综合分析,成功圈定目标区地热远景区,为该地区地热资源试采及进一步勘查与开发远景规划的制定提供依据。As a traditional frequency domain depth measurement method,the magnetotelluric exploration method has the advantag-es of large exploration depth,no shielding by low resistance layers,and high construction efficiency,and is widely used in geothermal investigations.The article takes the geothermal resource accumula-tion model in the Bortala River Valley area of Wenquan County,Xinjiang as the research object.Using two types of exploration da-ta,namely magnetotelluric sounding and controllable source audio magnetotelluric,the rock resistivity information is inverted and cal-culated.Combined with geological sounding,seismic structure in-terpretation and other results,they are mutually confirmed.Through comprehensive analysis,the geothermal prospect area of the target area is successfully delineated,providing a basis for the trial mining and further exploration and development of geother-mal resources in the region.
