【摘要】 受多种因素制约,上海市近年来陆续实施的地热资源勘查效果都不理想。本文在汇总整理本市有关地热资料的基础上,对区内热源、热储、热盖和通道等地质条件进行了分析,并划分了12个地热资源远景区。热盖为上侏罗统、松散层区域性热盖和上白垩统-古近系、下古生界陆源碎屑岩局部性热盖。热储具有下古生界和白龙港玄武岩层状热储和断裂破碎带带状热储。热源主要为正常的地温增温,断陷盆地盆缘断裂和主要断裂具有深部导热作用。更多还原

【Abstract】 Confined by several factors,the effect of geothermal resource exploration has not been effective,in recent years.Base on the data owning,this paper has analyzed the geological conditions from geothermal source,geothermal cover and geothermal reservoir,etc.,and recognized 12 geothermal resource prospective areas,and summarized 2D conceptual model of geothermal resource.Geothermal cover includes regional cover composed of upper Jurassic,loose bed and partial cover composed of upper Cretaceous,Paleocene,lower Paleozoic terrigenous clastic rocks.Geothermal reservoir develops layered reservoir including lower Paleozoic,Bai Longgang Basalt and banding reservoir of fault belts.Heat is mainly from Geo-temperature gradient,the faults of faulted depression brink and main deep faults can conduct the deep heat.更多还原
