区域地质调查和地热地质勘探资料显示，临沂市柳航头地区区域构造发育较强烈，大气降水通过构造破碎带向地下深部运动，深部寒武奥陶纪灰岩岩溶地层厚度可达1500余米。区域地下水在深部渗透性较好的岩溶地层内径流，向柳航头地区运动过程中，不断受到地球深部热源的地温加热而形成地热水，寒武奥陶纪岩溶地层成为热储层，其上覆地层导热率较低，是较好的盖层。结合研究区内的地热井深部测温数据和地热水化学特征数据，建立柳航头地区地热概念模型。

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 tecton-ic 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 conductivi-ty. Combining with the research of deep geothermal well temperature and chemical characteristics of geothermal wa-ter, geothermal conceptual model of Liuhangtou area has been established.
