太湖南岸地热资源现状及资源潜力评价

Geothermal Resource Status Quo and Resource Potential Assessment in Taihu Lake South Bank Area

根据热储埋藏条件、盖层、导热构造、地形地貌的总体特征,将太湖南岸地热资源区划分为湖州太湖南岸地热资源区、湖州小梅口地热资源区和湖州苍山地热资源区3区。通过计算区内地热流体年开采累计可利用热能量、热储中的热量、热储中岩石的热量和热储中水的热量,得出太湖南岸地热资源区热储中的热量是现有7口地热井年开采累计可利用热能量的1162倍,其中,热储中水的热量是现有7口地热井年开采累计可利用热能量的126倍,热储中岩石的热量是现有7口地热井年开采累计可利用热能量的1036倍,研究表明太湖南岸地热资源区可利用的地热资源丰富、潜力巨大。初步预测太湖南岸地热资源区东西两侧广大区域内均有可能存在丰富的地下热水资源,可作为今后地热资源勘查的重要区域。

According to geothermal reservoir buried condition,overburden,thermal conducted structure,topographic and landform overall features have partitioned the Taihu Lake south bank geothermal resource area into Huzhou Taihu Lake south bank,Huzhou Xiaomeikou,and Huzhou Cangshan 3 geothermal resource subareas.Through computation of the area’s geothermal fluid annual exploitation available thermal energy,reservoir thermal amount,reservoir rock thermal amount and reservoir water thermal amount have worked out thermal amount in Tainu Lake south bank geothermal resource area is 1,162 times of present 7 geothermal well annual exploitation accumulative available thermal energy.In which,reservoir water thermal amount is 126 times of present 7 geothermal well annual exploitation available thermal energy;reservoir rock thermal amount is 1,036 times of present 7 geothermal well annual exploitation available thermal energy.The study has shown that the area’s available geothermal resources are abundant with huge potential.This paper has predicted within the area’s east and west sides vast area is likely existed abundant geothermal water resources and this area can be important exploration area henceforth.
