Description
Summary:We applied CSAMT and the resistivity method based on Wenner device to the fault structure detection in a geothermal field target area, and carried out hydrogeological drilling in the geophysical anomaly area. The temperature measurement results in the well showed that the groundwater temperature is more than 50°C, which verified the effectiveness of the comprehensive geophysical method in geothermal resource exploration. The conclusions show that the resistivity method and CSAMT are suitable for the detection of thermal storage fault structures, and the comprehensive analysis method combined with the two methods can more accurately determine the plane distribution and occurrence of concealed fault structures.
