杭嘉湖平原水热型地热资源综合评价与开发利用建议

COMPREHENSIVE EVALUATION AND SUGGESTIONS FOR DEVELOPMENT AND UTILIZATION OF HYDROTHERMAL RESOURCES IN HANGZHOU-JIAXING-HUZHOU PLAIN

通过对杭嘉湖地区水热型地热资源进行综合评价可知,该区地热储量为439.18×10^(14)kJ,地热流体储存量为212.22×10^(8)m^(3),地热流体可开采量为16864.8×10^(4)m^(3)/a,地热流体可开采热量为2366.88×10^(10)kJ/a,可用于旅游疗养、地热供暖、水产养殖等方向.建议地热资源的开发利用应开采与保护并重,做到科学规划、合理开发、绿色可持续发展.除用于旅游疗养外,该区地热资源可结合入特色农业、地质文化村等建设中,形成梯级综合利用模式;可结合区内丰富的浅层地热能资源,形成深浅结合的利用模式;还可结合热泵技术、太阳能技术、空气能技术等清洁能源技术,形成“地热+”复合开发模式.

The comprehensive evaluation of hydrothermal resources in Hangzhou-Jiaxing-Huzhou region shows that the geothermal reserves is 439.18×10^(14)kJ,with the geothermal fluid storage of 212.22×10^(8)m^(3),the exploitable geothermal fluid of 16864.8×10^(4)m^(3)/a,and the exploitable heat of 2366.88×10^(10)kJ/a,which can be used for convalescent tour,geothermal heating and aquaculture.It is suggested that the local authorities should pay equal attention to the protection of geothermal resources in the process of development and utilization to achieve scientific planning,rational exploitation and green sustainable development.Besides,the geothermal resources can be combined with the characteristic agriculture and construction of geological cultural village to form a cascade comprehensive utilization mode,combined with the abundant shallow geothermal energy resources to form a deep-shallow combination utilization mode,and combined with clean energy technologies such as heat pump,solar energy and air energy to form a“geothermal+”compound development mode.
