摘要
菏泽地热田内蕴藏着丰富的地热资源,地质构造条件、热储地质条件都比较有利,是开发地热资源的有利地段。区域地质构造主要为聊考断裂和曹县断裂,热储层分2大类呈双层结构,上部为新近系孔隙-裂隙热储,下部为奥陶系碳酸盐岩裂隙岩溶热储。该区地下热水是50年前形成的,水中氟、偏硅酸达到矿水命名浓度,为氟水、硅水;锶已接近锶水;偏硼酸已接近矿水浓度,还含有F-,H2SiO3,HBO2,Li等多种对人体有益的矿物元素,可作为采暖,洗浴等用水。
Geothermal resource is very rich in Heze geothermal field. Geological tectonic conditions, geothermal reservoirs are relatively favorable for exploiting geotherm. Regional geological structures are mainly composed of Liaokao fault and Caoxian fault. Geothermal reservoir was divided into two major double-decker structure, the upper part is Neogene pore-fractured geothermal reservoir, while the lower part is the Ordovician carbonate fractured karst geothermal reservoir. Underground geotherm was formed in 50 years ago. The contents of fluoride in water and pianguisuan can reach the degree for naming as mineral water. The geotherm also contains some useful mineral elements, such as F^- , H2SiO3, HBO2 and Li. Thus, it can be used in heating and bathing as well.
