金华市区浅层地温能资源量评价

Evaluation of shallow geothermal energy resources in Jinhua urban area

在分析金华市区的地层岩性与水文地质条件的基础上,结合岩土体热物性测试所获得的参数,对金华市区浅层地温能热容量进行计算,得到金华市区80、100和120 m以浅浅层地温能热容量分别为1.87×10^14、2.35×10^14、2.82×10^14 kJ/℃,其中重点研究区浅层地温能热容量分别为1.01×10^14、1.27×10^14、1.52×10^14 kJ/℃。对重点研究区的浅层地温能资源量进行评价,获得地埋管地源热泵系统可利用的浅层地温能资源量分别为3.38×10^13、4.20×10^13和4.98×10^13 kJ,为浅层地温能的开发利用提供科学依据和重要的数据支持。

Based on introducing formation lithology and hydrogeological conditions of Jinhua urban area,combined with the various thermal parameters obtained from rock and soil thermal physical properties test,the shallow geothermal capacity in Jinhua urban area was calculated.In this way,the shallow geothermal capacity in the depth of 80 m,100 m and 120 m were 1.87×10^14 kJ/℃,2.35×10^14 kJ/℃and 2.82×10^14 kJ/℃,respectively.Especially,the shallow geothermal capacity in the major research area were 1.01×10^14 kJ/℃,1.27×10^14 kJ/℃and 1.52×10^14 kJ/℃,respectively.In addition,the shallow geothermal energy resources of the major research area were evaluated,and the results showed that the amount of available shallow geothermal energy resources that could be used by buried pipe ground source heat pump system were 3.38×10^13 kJ,4.20×10^13 kJ and 4.98×10^13 kJ,respectively,providing a scientific basis and an important data source support for the development and utilization of shallow geothermal energy resources.
