摘要
本文对部分穿透高导电性多孔地下含水层的抽井流量进行了计算机分析。分析中评价了抽油机井、3口部分穿透观测井和6个短筛压力表的水位损耗情况。WT软件考虑了上覆非饱和带脱水引起的延迟重力排水。这种流动被模拟为漫漫性横流或从顶部不透水的水槽中泄漏。采用Hantush（1962）的分析方法，利用所有观测井和压力计的后期压降数据确定含水层参数。利用PEST软件对含水层性质进行了优化，并推测了抽油井的层状比径向损失参数。结果与之前的两个分析进行了比较。kr和kz参数与Moench et al.（2001）的相关数据拟合，而Sy参数与Tartakovsky和Neuman（2007）的数据接近。为s参数找到了一个中间值。
Estimation of Hydrogeologic Parameters at the Cape Cod Hydrology Research Site.
The article deals with computer analysis of flow to pumping well partially penetrating the high conductivity porous water table aquifer. Water level depletion in the pumping well, 3 partially penetrating observation wells, and 6 piezometers of short screen are evaluated in the analysis. The WT software considers the delayed gravity drainage caused by dewatering of the overlying unsaturated zone. This flow is emulated as diffusive crossflow or leakage from an aquitard with an impervious top. The analytical method by Hantush (1962) is applied to confirm the aquifer parameters using the late time drawdown data in all observation wells and piezometers. The software PEST is employed to optimize the aquifer properties and the presumably laminar specific radial loss parameter of the pumping well. The results are compared with two earlier analyses. The kr and kz parameters fit the relevant data by Moench et al. (2001), whereas the Sy parameter is close to the value by Tartakovsky and Neuman (2007). An intermediate value is found for the Ss parameter.
