贵州黔东南州北西部地热水资源量估算与评价

Estimation and evaluation of geothermal water resources in the Northwest of Qiandongnan Prefecture,Guizhou Province

贵州省黔东南州北西部地热资源整装勘查为2013年度省地质勘查基金整装勘查项目(第三批),勘查区受挽近期活动构造带的影响,区内断裂储热、导热较好,热储单元条件较好,热储主要为带状热储,带状热储主要是指受断裂控制,沿断裂带呈带状分布的热储。文章通过对勘查区地质、构造、水文地质及地球物理等特征综合分析后,勘查区的热储类型主要为典型带状热储,其储水、储热、导热层均为断层破碎带,其地热水资源量估算与评价具有一定代表性。

Geothermal resources reconnaissance in the north and west of Qiandongnan Prefecture,Guizhou Province is the third batch of reconnaissance projects of the Geological Exploration Fund of Guizhou Province in 2013. The exploration area is affected by the recent active tectonic belt of pulling. The faults in the area have good heat storage and conduction,and the conditions of thermal storage units are good. The thermal reservoirs are mainly zonal ones. The zonal thermal reservoirs are mainly controlled by faults and distributed along the faults. Based on the comprehensive analysis of geological,structural,hydrogeological and geophysical characteristics of the exploration area,the main types of thermal reservoirs in the exploration area are typical zonal thermal reservoirs,whose water storage,thermal storage and thermal conductivity are fault fracture zones,and the estimation and evaluation of geothermal water resources are representative.
