摘要
根据雄安新区雄东片区浅层地热能的地温场和热物性等赋存条件,估算了雄东片区浅层地热能静态储量和资源潜力,评价了开发利用的经济环境效益。经计算,雄东片区150 m以浅浅层地热能热容量为4.7×10^(12)kJ/℃,静态储量为23.4×10^(12)kJ,制冷工况下资源潜力为43.3万m^(2)/km^(2),供暖工况下资源潜力为85.9万m^(2)/km^(2)从经济效益角度评价,当浅层地热能开发利用率为25%时,雄东片区全年大约可节约6077吨标准煤,全年大约可节约费用2006万元,可减排二氧化碳14501吨、减排二氧化硫103吨、减排粉尘49吨。
According to the occurrence conditions and distribution characteristics of shallow geothermal energy resources in Xiongdong area of Xiongan New Area,the potential of shallow geothermal energy resources in this area is estimated,and the exploitation and utilization is evaluated from the perspective of economic and environmental benefits.The results show that the total shallow geothermal capacity of 150m shallow rock and soil bodies in Xiongdong area is about 4.7×10^(12)kJ/℃,the total static reserves of shallow geothermal energy are about 23.4×10^(12)kJ,and the average resource potential of buried pipe heat transfer under summer cooling conditions is 433,000 m^(2)/km^(2).The average resource potential of heating conditions in winter is 859,000 m^(2)/km^(2).From the perspective of economic benefit,when the utilization rate of shallow geothermal energy development is 25%,about 6077 tons of standard coal can be saved in Xiongdong District throughout the year,about 2006 million yuan of annual cost can be saved,14,501 tons of carbon dioxide can be reduced,103 tons of sulfur dioxide can be reduced,and 49 tons of dust can be reduced.
