贵阳市龙洞堡地区地热水成因及其特征研究
|
摘要
贵阳市地热水开发已多年,本文选取地热水开发新区龙洞堡进行研究,对其地热水成因、地温以及地下水化学特征等进行分析。结果表明:该区地热水主要储存于寒武系白云岩中,地热水贮藏条件良好且水量充足,上部有厚层砂岩作为保温层,区域的深大断裂为其提供了良好的热运输通道,地热水经过较长的水岩作用物质含量较高,地热水水化学类型为SO_4—Ca型水,其中锶、氟、偏硅酸的含量较高,水温、水质适合,具有一定的理疗效果,适用于进行温泉洗浴产业的开发。
The development of geothermal water in Guiyang City has been for many years.In this paper,geothermal water was selected to develop the Longdong Fort of the new district.The causes of geothermal water,geotemperature and the chemical characteristics of groundwater were analyzed.The results show that the geothermal water in this area is mainly stored in the Cambrian dolomite.Geothermal water is well-stored and has adequate water volume.Thick sandstone is used as the thermal insulation layer in the area,and the deep faults in the area provide good heat transport Channel,geothermal water after a long time the role of high water and rock matter,geothermal water chemical type of SO4-Ca-type water,strontium,fluoride,metasilicate content is higher,water temperature,water quality suitable,with a certain Therapeutic effect,suitable for hot spring bathing industry development.
