摘　　要：河北省地热资源较丰富,开发利用历史悠久,断陷盆地地热资源具有量大、质优的特点,具备大规模开发利用价值。本文通过热储法对冀西北赤城断陷盆地进行进行系统评价,结果表明赤城断陷盆地地热资源量达662.85×10^(16)J,地热水储量达34.43×10^(8)m^(3),估算100年的地热流体可开采量为1.72×10^(8)m_(3)。年可采热水资源热量272×10^(6)MJ,折合热能10.08MW,计算折合标煤9280.87t/a,减排二氧化碳22144.15t/a,具有显著的经济环境效益,对实现“双碳”目标具有重要作用。Hebei Province is rich in geothermal resources,with a long history of development and utilization.The geothermal resources in the fault basin have the characteristics of large quantity and high quality,and have the value of large-scale development and utilization.The results show that the geothermal resources in the Chicheng fault basin are 662.85×10^(16)J,the geothermal water reserves are 34.43×10^(8)m^(3),and the recoverable amount of geothermal fluid in 100 years is estimated to be 1.72×10^(8)m^(3).The annual recoverable heat of hot water resources is 272×10^(6)MJ,equivalent to 10.08MW of thermal energy,equivalent to 9280.87/a of coal-fired energy,and 22144.15t/a of carbon dioxide reduction,which has significant economic and environmental benefits and plays an important role in achieving the"double carbon"goal.
