Vertical recirculation wells used for remediation or heat recovery induce drawdown distribution that varies for confined, unconfined, leaky, and reservoir-covered aquifers. A recirculation well with arbitrary arrangement of extraction and injection screen intervals is simulated with the general well function of Perina and Lee (2006) and Perina (2014) after a minor modification. Distribution of radial flux along the screen intervals is determined as part of the solution for the mixed boundary condition along the well-aquifer interface. Drawdown distribution reaches steady state, with the transient period lasting over one year for unconfined aquifer and less than one hour for the other three aquifer types in the example considered. The drawdown distribution varies by aquifer type and shows sensitivity to aquifer hydraulic properties and well construction, suggesting that a recirculation well offers an effective and economical alternative to pumping tests for characterization of aquifer hydraulic properties.

用于修复或热回收的垂直再循环井引起的下降分布因承压、非承压、渗漏和储层覆盖的含水层而异。采用 Perina 和 Lee (2006) 和 Perina (2014) 的一般井函数在稍作修改后模拟了具有任意布置的提取和注入筛管间隔的再循环井。沿滤网间隔的径向通量分布被确定为沿井-含水层界面的混合边界条件解的一部分。下降分布达到稳定状态，在所考虑的示例中，非承压含水层的瞬态持续时间超过一年，而其他三种含水层类型的瞬态持续时间不到一小时。
