The Research Of Geothermal Resources Assessment And Development On The Sedimentary Basin In Zhejiang Province

The geothermal resource exploration in the Hangjiahu Plain and Ningshao Plain and the other place started late.The current results of prospecting is still not ideal which can not meet market demand.At present,the geothermal resources in this area are mainly used in physical therapy and bath,lack of rational development and utilization planning.Resource utilization is low.Therefore,it is helpful to analyze and summarize the distribution of the sedimentary basin geothermal resources in Zhejiang Province.Resources assessment and research of development of geothermal resources in this region will have the important guiding significance to the next geothermal geological prospecting works,also will help how to reasonably develop and geothermal resources,protect the ecological environment and improve the geothermal resource utilization efficiency.Based on the data collected,geothermal geology survey and geothermal wells(springs)field investigation,the investigation of the development and utilization of geothermal resources and geothermal resource evaluation methods,analyze and sumlarize the distribution and the occurrence conditions of sedimentary basin type geothermal resources in Zhejiang province and the type of geothermal fluid water chemical characteristics are analyzed.Then,the sedimentary basin type geothermal resources in the province are calculated and evaluated,and the type of geothermal fluid quality is evaluated.Finally,this paper expounds the sedimentary basin type geothermal resources development and utilization prospect in Zhejiang province,study this paper probes into the problems in the process of development and utilization,and puts forward suggestions on the rational development and utilization.First,this research has carried on the thorough investigation to the general situation of the geothermal resources in Zhejiang province.Including the geothermal geological survey of geothermal geological conditions,regional terrestrial heat flow characteristics,regional geothermal field characteristics,and so on.And including the investigation of the development and utilization.In addition,the geothermal fluids were sampled and analyzed.Secondly,this research has carried on the type division of the geothermal resources in Zhejiang province.On this basis,this study focuses on the analysis of the distribution characteristics and formation mechanism of the sedimentary basin geothermal resources in Zhejiang province.And the correlation analysis of the water chemistry characteristics of this type of geothermal fluid is carried out.Then,based on the combination of theoretical model and geological survey results,this study evaluated the sedimentary basin geothermal resources in Zhejiang province.The content of the evaluation includes the total geothermal resources storage,the total geothermal fluid storage,the total exploitable geothermal fluid storage,the total exploitable geothermal fluid heat,and the quality of geothermal fluid.Finally,the history of the development and utilization of geothermal resources in Zhejiang province was studied.And the development and utilization status of the sedimentary basin geothermal resources in Zhejiang province were analyzed.On the basis of this,combined with the survey and evaluation of the results,this study put forward constructive suggestions for the future development of geothermal resources in Zhejiang province.
