摘要
During the geothermal exploration in Longmenxishan of Luoyang and Luoyang basin,such integrated geophysical methods as audio frequency ground electric field ΔU measurement,radiometric α measurement and IP sounding were employed and,as a result,four hot water wells of concealed faulted structure type were successfully determined,in which the highest temperature reached 98.5 ℃,and the water quantity was as high as 96 m3/h,suggesting the important role of geophysical methods in search for hot water of concealed faulted structure type.The genesis of the high temperature geothermal wells is tentatively discussed in this paper.
