A wide variety of well drilling techniques and well completion methods is used in the installation of dewatering and artificial recharge wells for the purpose of construction dewatering. The selection of the optimal well type is always a trade-off between the overall costs of well completion and development, the optimal well hydraulics of the well itself, the hydraulic impact of the well on its surroundings, and the required operational life span of the well. The present study provides an analytical framework that can be used by dewatering and drilling companies to quantify the contribution to head loss of typical dewatering and artificial-recharge well configurations. The analysis shows that the placement of partially penetrating wells in high-permeability layers could promote the use of quick and cheap installation of naturally developed wells using jetting or straight-flush rotary drilling. In high-permeability layers, such wells can be favorable over wells completed with filter pack, which require extensive well development to remove the fines from the filter cake layer. The amount of total head loss during discharge/recharge at a volumetric rate of 20 m³/h per meter of filter length, into or from a gravely aquifer layer, is reduced by factors of 3–4 while using naturally developed well types instead of well types completed with a filter pack that contains a filter cake layer due to borehole smearing.

为了进行建筑脱水，在脱水和人工补给井的安装中使用了各种各样的钻井技术和完井方法。最佳井类型的选择始终是在完井和开发的总成本，井本身的最佳井水力，井对周围环境的水力影响以及所需的使用寿命之间进行权衡的问题。好。本研究提供了一个分析框架，可以由脱水和钻井公司用来量化典型的脱水和人工补给井配置对压头损失的贡献。分析表明，将部分渗透井放置在高渗透率层中，可以促进使用快速或廉价的自然开发井（通过喷射或同井旋钻）进行安装。在高渗透率层中，这样的井可能会比带有过滤组件的井更为有利，后者需要大量的井开发才能从滤饼层中除去细屑。容积率为20 m的放电/充电过程中的总压头损失量使用自然开发的油井类型，而不是由于井眼拖尾而使包含滤饼层的滤芯完成的油井类型，每米滤池长度（进入或离开严重的含水层）的³ / h降低3-4倍。
