摘要
京津冀地区雾霾较为严重,同时地热资源丰富,因此,充分利用地热资源是调整该地区能源结构,减缓雾霾的重要途径之一。本文在分析京津冀地区构造、大地热流、地温梯度等地质背景的基础上,分别总结了京津冀地区隆起山地对流型与沉积盆地传导型地热资源的成藏模式与赋存条件,并对两种地热资源的资源量、开发利用现状与潜力进行了分析。京津冀地区地热资源储量折合标准煤约1383亿t,年地热流体可开采热量折合标准煤1100万t,但目前地热流体年开采热量仅相当于114万t标准煤,约占总量的10%,开发利用潜力巨大。
Haze in Beijing-Tianjin-Hebei region is relatively heavy;at the same time,this region is rich in geothermal resources.The development of geothermal resources can contribute to the energy structure adjustment and the control of haze in that region.In this paper,based on the analysis of the fracture,strata,terrestrial heat flow and geothermal gradient of Beijing-Tianjin-Hebei region,the authors summed up the formation mode and hosting conditions of convection geothermal and conductive geothermal resources respectively.The quantity,exploitation situation and the development potential of geothermal resources were also calculated.The result shows that geothermal resource reserves are equivalent to about138.3billion tons of standard coal,and heat in geothermal fluid of the local region amounts to about11million tons of standard coal.Nevertheless,the exploitation quantity is only equivalent to about10%of the total resources,and hence the potential for geothermal resources development and utilization is huge.
