摘要
干热岩作为重要地热资源的组成部分,具有清洁、稳定、可再生的资源优势及巨大的高温发电潜力。基于河北省地温场分布特征,地热地质背景、大地热流、酸性岩体分布及盖层特征,初步认为省内基岩构造凸起区或山间盆地构造活动区存在低孔隙度、渗透性而缺少流体的隐伏高温变质岩系。综合分析初步圈出了6块干热岩地热资源赋存潜力区。在此基础上结合国内外干热岩成因机制分析将河北省干热岩地热资源的赋存类型分为沉积盆地型、沉积盆地型叠加高温放射型、近代火山型和板块俯冲型4种成因模式。
As an important geothermal resources component,the hot and dry rock has clean,steady and reproducible resource superiority and huge high temperature power generation potential.Based on geothermal field distribution features,geothermal geological setting,telluric heat flow,acidic rock mass distribution and overburden features in the Hebei Province,initially considered that in bedrock structural protruding region or intermountain basin tectonically active region have existed low porosity,low permeability and lack of fluid concealed high temperature metamorphic rock series.The comprehensive analysis has initially delineated 6 hot and dry rock geothermal resource hosting potential regions.On this basis,combined with home and abroad hot and dry rock genetic mechanism analyses partitioned the hot and dry rock geothermal resource hosting type in the province into sedimentary basin type,sedimentary basin superimposed high temperature radiation type,modern volcanic type and plate subduction type 4 genetic models.
