鹤壁新城区浅层地热能资源开采适宜性分区与评价

摘要

浅层地热能是一种新型能源,资源分布广泛,适宜就地开发利用,且对环境危害小.随着鹤壁市城市规模的扩大及新城区的建立,对能源的需求量加大,同时需对环境进行保护,鹤壁新城区浅层地热能开发与评价日趋重要.在充分收集已有地质、水文地质、工程地质等资料的基础上,运用了调查、钻探、取样和现场试验等方法,并运用层次分析法(AHP)对鹤壁新城区浅层地热能适宜性分区进行综合评价,划分为适宜区、较适宜区及不适宜区.用该方法得出的分区结果合理可靠,为鹤壁新城区浅层地热能的开发利用提供了科学依据.%Shallow geothermal energy is a kind of new energy,this resources is distributed widely and suitable to developing in-situ,the same time is litde harm to the environment.With the development of Hebi city's size,the new city zone is being built,the energy demand is increasing,and also the environmental protection requirements,so the extraction of shallow geothermal energy in Hebi city is become more and more important.Based on existing data such as hydrogeology,engineering geology and the initial site survey,shallow geothermal energy survey,drilling,sampling,field test were carried out.Then using the AHP to assess the suitability for use of shallow geothermal energy in the new city zone of Hebi.According this method,the authors divided the new city zone of Hebi into the suitable,general suitable and unsuitable subareas.The result of suitability division is proved reasonable and reliable.The assessment will provide a scientific basis and supporting system for the development and utilization of shallow geothermal energy in the new city zone of Hebi.
