Abstract
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.
Highlights
Geothermal resource is a kind of valuable clean energy, which can be used for heating and power generation, and provide medical hot spring water source
Fault structure is the main channel of underground hot water migration and temperature conduction
It is important to find out the spatial distribution characteristics of fault structures in the survey area for geothermal resources exploration, and it is of great significance to evaluate the reserves of deep geothermal resources
Summary
Geothermal resource is a kind of valuable clean energy, which can be used for heating and power generation, and provide medical hot spring water source. Drilling method and geophysical prospecting method are two kinds of commonly used geothermal resources exploration methods, the former is intuitive and accurate, but the exploration cost is high It is mostly used for the verification of geophysical anomaly area, and the geophysical method has high efficiency which is suitable for the area detection of fault structure in geothermal field target area. Radon measurement method is a kind of radioactive detection technology which can indirectly infer the plane distribution and tendency of underground structures by measuring the radon content in the soil. This method can not obtain the vertical distribution characteristics of the structure, and is mostly used for the general survey of geothermal resources. The research contents of this paper can provide reference for the improvement of geothermal resources exploration technology
