摘　　要：地热资源是清洁环保的新型可再生能源,河南省沿黄地区浅层地热能和深层地热水资源丰富,开发利用浅层地热能和深层地热水资源可以缓解资源与环境压力、减少二氧化碳排放量、促进生态文明建设与经济可持续发展。河南省沿黄8个主要城市浅层地热能可开采资源量为6.4489×10^14 kJ/a,折合标准煤2200.55万t/a;沉积盆地埋深2500 m以上热储层储存的地热流体量约3.12万亿m^3,地热流体可开采量约为7662万m^3/a,可利用的热能量约10.88万亿kJ/a,折合标准煤约37.13万t/a;隆起山地地热流体可开采量为838.77万m^3/a,可利用热能量为2.318494×10^16 J/a,折合标准煤78.80万t/a。通过分析河南省沿黄地区地热地质、水文地质条件、成因类型及分布等,探讨了浅层地热能开发利用适宜性和开发利用潜力,以及地热资源勘查与开发利用存在的问题,提出应在整体规划、合理开发和有效利用地热资源的前提下,大力开发利用浅层地热能和深层地热水资源。Geothermal resources are new clean and green renewable energy.The Yellow River Basin in Henan Province is rich in shallow geo⁃thermal energy and deep geothermal water resources.The development of them can alleviate the pressure on resources and the environment,reduce carbon dioxide emissions andpromote ecological progress and sustainable economic development.The amount of recoverable resources of shallow geothermal energy in eight major cities along the Yellow River totals 6.4489×10^14 kJ/a,which is equivalent to 22.0055 million t/a of standard coal.The amount of geothermal fluid stored in thermal reservoirs with a depth of more than 2500 m in the sedimentary basin of the Yellow River Basinis about 3.12 trillion m^3,the recoverable amount of geothermal fluid is about 76.62 million m^3/a,and the available thermal energy is about 10.88 trillion kJ/a,equivalent to about 37.13×10^4 t/a of standard coal.The geothermal recoverable resources of ten geothermal fields including Wentang geothermal field in Shaanzhou in the west of Sanmenxia City were calculated.The recoverable amount of uplift mountain geothermal fluid is 838.77×10^4 m^3/a,and the available thermal energy is 2.318494×10^16 J/a,which is equivalent to 78.80×10^4 t/a of standard coal.After analyzing the geothermal and hydrogeological conditions,genetic types and distribution,the feasibility and prospect of development and utilization of shallow geothermal energy as well as issues arising from them were discussed.It is proposed that on the premise of overall planning,rational development and effective use of geothermal resources,we will scale up the development and utiliza⁃tion shallow geothermal energy and deep geothermal water resources significantly.
