江西省通天寨地区地热水资源赋存规律研究

Study on Regularity of Geothermal Water Resources in Tongtianzhai Area of Jiangxi Province

石城县一带赋存较为丰富的地热水资源。石城—寻乌断裂带是通天寨地区的主断裂带,为活性断层,规模大,分布广。断裂有沟通深部热源的作用,是形成石城通天寨地热水资源的根本条件。通天寨地热水赋存规律受地形地貌、大气降水、地层岩性和地质构造的影响,其中,主要受地质构造的影响。地热水的形成机制为地表水沿断裂中的裂隙和孔隙入渗到地球深部,经过热流增温和吸收岩石的热量,沿着断裂裂隙和岩石孔隙上升,最终储存在热储层中形成地热水。

Shicheng County area has abundant geothermal water.The Shicheng—Xunwu fault,a large scale and widely distributed active fault,is the main fault in the Tongtianzhai area.The fault has the effect of communicating the deep heat source,which is the fundamental condition for the formation of hot water resources in Shicheng Tongtianzhai.Regularity of geothermal water resources in the Tongtianzhai area is affected by topography,rainfall,lithology and geological structure,of which,it is mainly affected by geological structure.The mechanism of geothermal water is that the surface water penetrates deep into the earth along the cracks and pores in the fracture,warms and absorbs the heat of the rock through heat flow,rises along the fracture cracks and rock pores,and finally stores in the thermal reservoir to form geothermal water.
