Target delineation and drilling verification of geothermal resources exploration in Hangjiahu plain of Zhejiang Province

Abstract：Based on the achievements gained in the implementation of the project "Exploration of Geothermal Resources in Hangjiahu Plain of Zhejiang Province," in combination with regional geological setting, the authors made a detailed geothermal- geological analysis of geothermal resources in Hangjiahu plain in such key technological aspects as the source, the communication, the cover, and the storage". It is shown that the geothermal resource is of the faulted sag basin type. Six geothermal exploration target areas were delineated. Drilling verification shows that the Hangjiahu area has great geothermal resource potential.
