In order to analyze the impact of CO₂ injection temperatures on heat extraction rate and the sustainability of CO₂-EGS, five cases with different CO₂ injection temperatures ranged from 18℃ to 42℃ are designed. Simulation results show that the range of the average heat extraction rate for those five cases is 6.56～8.47MW in the entire period of CO₂-EGS operation. The heat extraction rates vary over time and the rate is 6.37～7.9MW in the stage of CO₂ and water displacement and the rate is 6.64～8.68MW after aqueous phase disappear, respectively. In whole process of CO₂-EGS, the temperature of production fluid decreases with a rate of 1.89～1.74℃/a and the system sustainable time is 10.58～11.49a. Injection temperature of CO₂ significantly impacts the heat extraction rate of EGS; however has a little impact on the sustainability of CO₂-EGS. Reducing CO₂ injection temperature in the range permitted by the CO₂-EGS operation is a good choice for CO₂-EGS. Those results could provide the reference for the geological storage and resource utilization of CO₂., authors=WANG Fugang, NA Jin, GENG Xinxin, authorsList=WANG Fugang;NA Jin;GENG Xinxin,

articleAbstract=以鄂尔多斯CO₂地质储存工程区马家沟组地层为人工地热储层,用TOUGH2软件建立以CO₂为传热载体的CO₂-EGS模拟模型,设计并模拟了5种不同的CO₂注入温度(18～42℃)条件下CO₂-EGS系统运行特征,分析了CO₂注入温度对热提取率和系统可持续性的影响。结果表明,5种方案的热量提取率在CO₂-水驱替阶段变化区间为6.37～7.9MW,在液相流消失阶段变化区间为6.64～8.68MW。整个CO₂-EGS系统运行期的平均地层热提取率为6.56～8.47MW,系统可持续时间10.58～11.49a,系统运行期温度下降速率为1.89～1.74℃/a。CO₂的注入温度对深层地热能系统热量提取率影响显著,对系统的可持续性影响较小。为了获得最大的经济效益,应在CO₂-EGS运行允许范围内减小CO₂的注入温度。研究成果可以为CO₂地质储存与资源化利用提供参考。,
