康定小热水地区山区断裂破碎带地热资源勘查与评价

Investigation and evaluation of geothermal resources of shattered fractures zones in mountainous areas of Xiaoreshui, Kangding

以康定市小热水地区为例,基于区域地层和地质构造形态,采用温泉点调查、大地电磁测深、钻探以及水文地质测试、放喷实验等技术手段,初步查明了研究区的温泉赋存规律、断裂构造延展形态,分析了热源特征、地热水含水层结构及补径排特征,最后评价区内地热资源开采潜力和允许开采量,可以为类似山区地热资源勘查与开发工作提供有益的参考。

Taking the mountainous areas of Xiaoreshui,Kangding as an example,based on regional stratigraphy and geological structures,a series of technical investigations including hot spring spot investigation,magnetotelluric sound.ing test,drilling test,hydrogeological test and discharge experiments were performed to ascertain the occurrence regulari.ty of hot springs and extension forms of shattered fracture structures,to analyze the characteristics of heat sources and structures and distributions of geothermal water aquifers,and to evaluate the exploration potential of the allowable pro.duction amount of geothermal resources.The present work can provide useful references for exploration and application of geothermal resources in similar mountainous areas.
