| 中文摘要 | 建立三维水热耦合数值模拟模型,对不同地下水天然流动情况下,含水层采能过程中及采能后地温场的演化进行了模拟和分析。结果表明,对于地下水流动较为显著的地区,地温场的变化幅度不仅受地下水天然流速的影响,还与井位布局方向密切相关。区域地下水的天然流速越大,系统停运期抽水井的温度恢复速度越快;对于相同地下水天然流速,地下水流向沿抽水井指向回灌井比垂直于抽灌井对之间连线方向的情况,抽水井温度变化幅度要小。; A 3-D numerical model which couples a groundwater flow model with the heat transfer was used to analyze changes in the geological temperature field during and after energy mining for various regional groundwater flow scenarios. The simulation results show that the temperature field changes are closely related with both the regional groundwater flow velocities and the relationship between the well pair locations and the natural groundwater flow. Higher regional groundwater velocities more quickly restore the temperature of the pumping well. For the same natural groundwater flow velocity, the temperature changes at the pumping well are smaller if the regional groundwater flows parallel to the well pair rather than perpendicular to the well pair.; 创新研究群体科学基金资助项目(50221903); 国家“九七三”基础研究基金项目(2005CB724202) |
