河北省沧县台拱带干热岩资源潜力评估

Hot Dry Rock Resource Potential Assessment in Cangxian Anticlise Zone, Hebei Province

沧县台拱带位于华北断陷盆地,处在凸凹相间配置的构造格局,新生界厚度适中,属于沉积盆地干热岩资源。经预测,区内5 km以浅干热岩资源量为2 405×1018J,相当于8.21×1010t标准煤产生的热量,赋存潜力巨大,开发利用这一洁净能源对缓解我省日益严重的环境污染形势具有重要的现实意义。

Through geothermal geological condition analysis in the Cangxian anticlise zone, North China fault basin depression and up- lift alternating structural framework. Cenozoic group thickness is moderate and contained sedimentary basin hot dry rock resources. Through prediction, hot dry rock resources above depth 5km in the area is 2 405×10^18J, amount to 8.21×10^10 tons equivalent of coal produced caloricity, thus huge hosting potential. Exploitation and utilization of the clean energy source have important practical significance to relieve increasingly serious environmental pollution situation in the province.
