The Sihe area of Fuxin city is a blank area to develop the geothermal resources. The fault location, depth of the heat stratum layer roof and its temperature are inferred by the integral geophysical survey (include gravity exploration, magnetic exploration, CSAMT and geoelectric field lithology detection) to identify the geothermal resources. As a result, the the exploration target area is determined and the location of drilling well is designed. It provides important basis for the next step of drilling work.
