摘要
安徽省地热资源丰富,开发潜力大。探讨地热资源分布规律及成藏模式对于优化安徽能源与产业结构优化调整和生态环境保护等具有十分重要意义。本文在分析安徽省地质构造、大地热流、地温梯度等地质背景的基础上,系统分析总结了安徽省地热资源的分布规律、热储岩性、地热流体水化学特征等,研究了安徽省隆起山地对流型和沉积盆地热对流型两类地热资源的赋存条件,提出了相应成藏模式。
Anhui Province is rich in geothermal resources,which have great development potential.It is of great significance to explore the distribution law and reservoiring model of geothermal resources for energy industry optimizing and restructuring and ecological environment protecting in the province.Based on analysis of geological backgrounds such as geological structure,terrestrial heat flow and geothermal gradient in the province,this paper systematically summarizes distribution law,lithology of thermal reservoir,hydrochemical characteristics of geothermal fluid,discusses conditions for occurrence of two types of geothermal resources,i.e.,convective type in uplift mountain area and convective type in sedimentary basin in the province,and puts forward corresponding reservoiring model.
