四川天府新区龙泉驿片区浅层地热能资源评价OACHSSCD

Sichuan Tianfu New Area is a key urban development new area,aiming at building a resource-saving and environment-friendly new district.Shallow geothermal resources are clean renewable resources,and its development and utilization can not only alleviate energy shortage,but also play the role of energy conservation and emission reduction.The measured average formation temperature above 200 m in the study area is 18.65～19.4℃,and the average thermal conductivity of the formation is 2.43 W/(m·℃).The western and eastern hilly or platform areas of Longquan Mountain are suitable for ground source heat pumps,accounting for 56.61%.The low mountainous area of Longquan Mountain in the central and eastern regions is relatively suitable for ground source heat pumps,accounting for 43.39%.All areas are unsuitable for groundwater source heat pumps.The total cooling power of shallow geothermal energy in summer is 1.41×106 kW,and the cooling area is 1.79×107 m2.The total heating power in winter is 1.13×106 kW,and the heating area is 1.92×107 m2.It is estimated that the development of shallow geothermal energy in study area can save 0.201 million tons of standard coal per year,reduce the emission of various types of waste gas and waste residue pollution by about 0.506 million tons.The effect of energy saving and emission reduction is remarkable.
