Study on the Occurrence Conditions of Shallow Geothermal Energy and Its Development&Utilization Potential in Huangshi Urban Planning Area

对黄石地区浅层地温能赋存条件及开发利用潜力的系统研究尚属空白。在系统分析黄石城市规划区浅层地温能赋存条件及相关热物性参数的基础上,开展浅层地温能开发利用适宜性分区及开发利用潜力评价。结果表明,研究区浅层岩土体地温为18~22℃,可开发利用条件较好;研究区地下水地源热泵建设较适宜区面积为6.94 km^(2),无适宜区;地埋管地源热泵建设适宜和较适宜区面积为367.11 km^(2)。综合分析认为,研究区地埋管地源热泵系统适宜区和较适宜区的可利用资源量为2.62×10^(4) kJ,夏季可制冷面积为3.71×10^(8) m^(2),冬季可供暖面积为4.79×10^(8) m^(2),为黄石城市规划区合理开发利用浅层地温能提供科学依据。

There is no systematic study on the occurrence conditions and exploitation potential of shallow geothemal energy in Huangshi area.Based on the systematic anlysis of the occurrence conditions and related thermophysical parameters of shallow geothermal energy in Huangshi urban planning area,the suitability zoning and potential evaluation of shallow geothermal energy development and utilization are carried out.The results show that the ground temperature of shallow rock and soil in the study area ranges from 18℃to 22℃,which has good development and utilization conditions;The suitable area for the construction of ground source heat pump in the study area is 6.94 km2,and there is no suitable area;The suitable area for the construction of ground source heat pump is 367.11 km2.Comprehensive analysis shows that the available resources of the suitable and more suitable area of the ground source heat pump system in the study area are 2.62×10^(4) kJ,and the cooling area in summer is 3.71×10^(8) m^(2),the heating area in winter is 4.79×10^(8) m^(2),which provides scientific basis for reasonable development and utilization of shallow geothermal energy in Huangshi urban planning area.
