摘　　要：介绍了含水层储能技术、江水源热泵技术、冰源热泵技术、浅层渗滤海水源热泵技术、地源热泵综合能源技术和地热综合梯级利用技术等浅层地热和中深层地热利用创新技术的基本工作原理。通过调研这些技术在长三角地区的应用案例,分析了其技术先进性、经济性以及需要解决的主要问题。结果表明,含水层储能要优化成井技术以避免对地下环境的破坏;江水源热泵技术难点在于水温、水质、水量以及运行管理上;冰源热泵对于冰浆的制备与输运系统提出了更高要求;浅层渗滤海水源热泵工程的实施必须要有适合的水文地质条件;地源热泵综合能源技术强调了供能系统的多元化和互补性,而地热综合梯级利用技术则是突出了用能系统的能量梯度化,这两种技术推广的关键在于经济性。This paper introduces the working principle of some new technologies of shallow geothermal and mid-deep geothermal utilization innovative technologies such as aquifer thermal energy storage(ATES),river water source heat pump,ice source heat pump,shallow infiltration seawater source heat pump,comprehensive energy of ground source heat pump and geothermal gradient utilization.By investigating the application cases of these technologies in the Yangtze River Delta region,this paper focuses on the analysis of their advanced technologies,excellent economy and the main problems to be solved.According to their respective characteristics,the prospects for the promotion and application of these innovative geothermal utilization technologies in regions rich in geothermal resources in China,including the Yangtze River Delta,are forecasted.For aquifer energy storage,well completion technology should be optimized to avoid damage to the underground environment.The difficulties in the promotion of river water source heat pump lie in operation management.Ice source heat pump puts forward higher requirements for the preparation and transportation system of ice slurry.The implementation of shallow infiltration seawater source heat pump project must have suitable hydrogeological conditions.The ground-source heat pump integrated energy technology emphasizes the diversification and complementarity of the energy supply system,while the geothermal integrated cascade utilization technology highlights the energy gradient of the energy consumption system.The key to the promotion of these two technologies is economy.
