基于TOUGH软件模拟加拿大BORDEN含水层储能试验

Numerical Simulation of Aquifer Thermal Energy Storage Experiment of Canadian BORDEN Based on TOUGH Software

介绍了含水层储能地下温度场和地下流场(TH)耦合运移的机理;针对加拿大BORDEN含水层储能试验及观测数据,根据实际土层工程地质、水文地质和初始温度条件,建立了BORDEN储能试验的TH耦合3D数值模型。将模拟结果与实际观测数据进行对比,二者非常接近,符合理论和实际观测情况;模拟了热羽逐渐移动的规律,证明利用TOUGH软件在地下TH耦合模拟方面的准确性和实用性,为将来的地下含水层储能工程设计提供理论基础和参考依据。

The thermal-hydrologic(TH) coupled migration mechanism of underground temperature and fluid field of ATES was introduced.Aiming at the Canadian BORDEN storage energy site test and observation data,according to engineering geological,hydrological and initial temperature conditions of actual soil layers,the TH coupled 3D numerical model of BORDEN test was built by TOUGH software.It shows that the simulation results are very proximal to the observation data and agreement with theoretical and practical observation situations.Moreover,the law about which the heat plume deviates gradually was also be simulated.It is proved that it is accurate and useful to apply TOUGH in the field of underground TH coupled simulation,which will supplies theoretical basis and references for engineering design of ATES in future.
