山东菏泽地区地热田地质特征

Geological Characteristics of Geothermal Fields in Heze Area of Shandong Province

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[CD*2]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，H2SiO3，HBO2，Li等多种对人体有益的矿物元素，可作为采暖，洗浴等用水。
