摘　　要：地热能作为一种分布广泛、储量丰富的清洁能源,不合理的开发利用会导致资源利用效率低下及一系列生态环境问题。选取山东省聊城临清典型地热分布区域,基于详细地热地质调查资料,探索构建基于“群井联动”的地热供暖模式,开展可行性及运行效益分析。结果表明:在保证相同供暖面积及供暖质量的基础上,构建的“群井联动”地热供暖模式可减少41.46%的地热资源开采量,大幅提高了地热资源最大利用效率,同时实现地热尾水回灌;静态投资回收期约为3年,运行20个供暖季总收益为2574.2万元,经济效益较好;采用该模式对重点工作区进行区块划分,有助于解决地热井密集、开发不均衡及无法施工回灌井等问题,可为其他地区的地热能供暖提供技术参考和应用示范。As a widely distributed and abundant clean energy source,geothermal energy may lead to inefficient resource utilization and a series of ecological environmental issues when improperly developed.The typical geothermal distribution area in Linqing,Liaocheng City,Shandong Province was selects as the research object.Based on detailed geothermal geological survey data,the construction of a“multi-well coordination system”geothermal heating model was explored and the feasibility analysis with operational benefit was conducted.The results demonstrate that the proposed coordinated multi-well geothermal heating mode can reduce geothermal resource extraction by 41.46%while maintaining equivalent heating coverage and quality standards,significantly enhancing maximum utilization efficiency of geothermal resources.The system simultaneously achieves geothermal tailwater reinjection with favorable economic returns.The static investment payback period approximates 3 years,and the total revenue over 20 heating seasons reaches 25.742 million yuan.Through zoning division implementation in key operational areas,this model effectively addresses challenges including dense well distribution,uneven development patterns,and difficulties in reinjection well construction.The findings provide technical references and application demonstrations for geothermal heating development in other regions.
