摘要
本文提出了一个承压含水层的三维对流-热弥散模型。该模型的控制方程中不仅包含传统的对流和传导项,还有热弥散项,后者在许多著作中常被忽略掉。模型用来描述上海贮能试验场的一系列含水层贮能试验(单井灌水试验,对井灌水-回采试验,群井灌水-回采试验)。温度计算值和野外观测资料拟合得很好(相对误差2.8—4.5％)。文中描述了使用的模型,并对温度分布的计算值和观测值进行详细比较。
A three-dimensional convection-heat dispersion model for a confined aquifer is developed. The governing equation of the model contains not only the convection and conduction terms that were usually considered, but also the heat dispersion term that was generally neglected in many papers. This model is used for describing a series of seasonal aquifer thermal energy storage tests made at the Shanghai site including the injection test in a single well, the injection production test in paired wells and the injecton-production test in a group of wells. The simulated temperatures agree very well with the field data (relative errors being 2.8—4.5%). A general description of the 3-D numerical model used is given, which is followed by a detailed comparison of simulated and observed temperature distributions.
