摘　　要：济南市东部地区地热地质条件较好,典型代表为章丘地热田。为了估算评价其地热资源,服务于进一步的预可行性勘查,该文在资料收集、野外勘查的基础上,依据地热地质条件及地热田勘查研究程度,确定奥陶纪灰岩裂隙岩溶层状、带状热储层为章丘地热田的主要研究对象。该文对章丘地热田地热能资源量、地热流体可开采量进行了计算。章丘地热田总面积为468.524km^2,在章丘地热田Ⅰ,Ⅱ计算分区385.225km^2范围内,地热资源总量为1.337×10^18J,折合标准煤0.4562×10^8 t,地热资源储量查明程度为推断的。按照最大允许压力降低值0.3MPa计算,章丘地热田奥陶系热储地热流体资源可开采量为6620.56m^3/d。按照地热流体可开采量计算的地热田产能为10.83MW,年开采累计可利用的热能量为5.690×10^8MJ,折合标准煤1.941×10^4t/a。通过该次评价,为持续做好该区的地热资源开发利用工作,带动当地经济发展,构建能源节约型社会提供了数据支持。The geological conditions of geothermal in eastern Jinan are good,and typical representative is Zhangqiu geothermal field.In order to estimate and evaluate its geothermal resources,and serve a further pre-feasibility survey,based on the data collection and field exploration,according to geological conditions of geothermal and geothermal field exploration research,the Ordovician limestone fissure karst layered and strip-like thermal reservoir are determined as the main research object of Zhangqiu geothermal field.The geothermal energy resources and geothermal fluid recoverable amount in Zhangqiu geothermal field are calculated.The total area of Zhangqiu geothermal field is 468.524km^2.In the area of 385.225km^2 inⅠandⅡcalculation area of Zhangqiu geothermal field,the total geothermal resource is 1.337×10^18 J which is equivalent to 0.4562×10^8t of standard coal.The degree of investigation of geothermal resource reserves is inferred.According to the maximum allowable pressure drop value of 0.3MPa,the recoverable amount of geothermal fluid resources of Ordovician thermal storage in Zhangqiu geothermal field is 6620.56m^3/d.The geothermal field capacity calculated according to the recoverable amount of geothermal fluid is 10.83MW,and the cumulative available thermal energy for annual mining is 5.690×10^8MJ which is equivalent to 1.941104t/a of standard coal.Through this research,theoretical support is provided for the development and utilization of geothermal resources in the area,driving local economic development and building an energy-saving society.
