靖安县项家地热水资源特征及成因分析

Analysis of Characteristics and Genesis of Xiangjia Geothermal Water Resources in Jing’an County

通过对项家地热水钻孔的井温和采样测试成果数据分析,结合区域地质背景分析了该地热水成因机理,结果表明,水温随深度增加而升高,大气降水为主要补给来源。地热水水质类型为HCOs CaNa型,不结垢,不能直接作为饮用水和农田灌溉用水,但可用于理疗、洗浴、采暖、温室等方向的开发利用。

By analysis of the well temperature and the sampling test results of Xiangjia geothermal water borehole,the genetic mechanism is analyzed base on the regional geological background,proving that the water temperature increases with the increase of depth,and the atmospheric precipitation is the main supply source;the water quality of geothermal water belongs to HCO3-CaNa type,which cannot be directly used for drinking and farmland irrigation but can be used for the development and utilization of physiotherapy,bathing,heating and greenhouse.
