Application of integrated electromagnetic methods in exploration of geothermal resource in Yinchuan Basin

The correct guidance of geothermal resources development was particularly important.In this paper,taking Shahu tourism area Pingluo Courtry,Ningxia,as an example,Combining the methods of the controlled source audio frequency magnetotelluric sounding and Geoelectric Field Lithology sounding,the fracture dip direction and angle were conjected with the method of controlled source audio frequency magnetotelluric sounding,the reservoir favorable zone was conjected using the lithologic sounding,then wells location were set according to the above results.Finally the largest water,highest temperature geothermal wells in the Yinchuan basin were obtained,which confirmed integrated geophysical methods in large sedimentary basin had a good application effect.
