Abstract:As showed by regional geological survey and geothermal exploration information, regional structures are widely distributed Liuhangtou area in Linyi city. Precipitation always infiltrates into deep underground along tectonic fracture zone. The thickness of Cambrian Ordovician limestone karst strata is more than 1500m. Regional groundwater runs in deep karst formation with good permeability. During the period of moving to Liuhangtou region, underground water continuously suffered from the geothermal heat of deep earth heat source, Cambrian Ordovician karst stratum become geothermal reservoir, while the overlying strata is good cap rock with low thermal conductivity. Combining with the research of deep geothermal well temperature and chemical characteristics of geothermal water, geothermal conceptual model of Liuhangtou area has been established.
