Abstract Seasonal storage of heat in shallow aquifers for increasing the efficiency of geothermal energy systems requires a proper monitoring strategy. We expanded our earlier work on harmonic pulse testing (HPT) to incorporate the effect of a temperature front moving into the reservoir due to injection of hot (or cold) water. Our analytical solutions were applied to monitor the thermal front evolution in a doublet system. Thermal front position and average temperature around the injector could indeed be characterized through the application of the proposed HPT interpretation. Additional analyses were carried out adding noise to evaluate the robustness of the interpretation methodology.

用于监测含水层热能储存热锋的脉冲测试

摘要 在浅层含水层中季节性储存热量以提高地热能系统的效率需要适当的监测策略。我们扩展了我们早期在谐波脉冲测试 (HPT) 方面的工作，将由于注入热水（或冷水）而导致温度前沿移动到储层中的影响。我们的分析解决方案用于监测双联系统中的热前沿演变。喷射器周围的热锋位置和平均温度确实可以通过应用所提出的 HPT 解释来表征。进行了额外的分析，增加了噪音，以评估解释方法的稳健性。
