Application of CSAMT in geothermal field in Dingqi Town,Zhenning County,Guizhou Province
Before the extraction of geothermal resources,the preliminary geophysical exploration can greatly reduce the ex-traction cost.At this study,two profiles(L1-L1'and L2-L2')were investigated by Controlled Source Acoustic Magneto-telluric(CSAMT)in Dingqi Town,Zhenning County,Guizhou Province,to find out the scale of regional geothermal re-source storage and the correlation between faults and thermal reservoirs.The result indicated that the reserves in the L1 pro-file are more abundant than L2 and more mining potential.The two faults serve as effective water and thermal channels for geothermal resources and the external environment.Meanwhile,a geothermal well drillingwas successfully carried out ba-sing on the results of geophysical interpretation,as well explored that the volume of geothermal water reaches 3 154 m3/d and temperature are 52.5 ℃.
