摘要
广东三坑地热田位于吴川—四会深大断裂带的东北侧 ,三坑向斜岩溶盆地内。地下热水主要赋存于 NE与 NW向断裂构造及其交汇部位的岩溶裂隙发育带中。根据地热地质条件及水热对流系统分析 ,地下热水是在水热对流系统中由深循环高温构造裂隙水与浅循环常温岩溶水混合而成。三坑地热田热水资源具有水温适中、水量丰富、水质良好、动态稳定等特点 。
The Sankeng geothermal field is located on the northeastern side of the Wuchuan Sihui deep fault and in the Sankeng synclinal karstic basin. The hot groundwater occurs mainly in NE and NW trending faults and karstic fissure zones at their intersections. Based on the analysis of geothermal geology and hydrothermal convection system, the hot groundwater is formed from the mixing of the deep circulating high temperature structural fissure water with the shallow circulating ordinary temperature karstic water in the hydrothermal convection system. The Sankeng thermal water resources of Sankeng geothermal field, being characterized by their moderate water temperature, abundant water quantity, good water quality and stable regime, has a great potential for exploitation.
