摘要

每天都有成千上万的水井为各种目的抽取地下水。这些井通常在没有充分了解当地水文地质和目标含水层的情况下选址和设计。不幸的是,不知情的油井选址和设计不仅在欧洲,而且在许多发展中国家都是常见的做法。这种做法不仅会危及油井的基本功能,而且还会导致许多被广泛引用的环境后果,如不希望的含水层水混合、危险的土壤沉降以及地表水或泉水的干涸。这篇简短的文章强调了地下水调查的关键程序,以便更明智地选址和设计井,以帮助减轻不期望的环境后果。这个主题在最近的文献中已经讨论过,但是本文基于作者的现实世界经验提供了对实践者可能有价值的实际见解。本文描述了一些重要的程序,这些程序应该是任何水井工程的一部分,无论要提取多少水。本文讨论了油井选址和设计的三个关键问题:1)初步调查的必要性和潜在的环境影响;2)应该参与这些调查的关键专家;3)水文地质学家的核心任务。给出了解释性数据和参考文献。

Water well drilling: tips and key points to consider in water well design
Thousands of water wells are drilled every day to abstract groundwater for a range of purposes. These wells are frequently sited and designed without adequate knowledge of the local hydrogeology and the targeted aquifer. Unfortunately, uninformed well siting and design is a common practice not only in Europe but also in many developing countries. The practice can not only jeopardize basic well function but also lead to a number of widely cited consequences to the environment, such as, undesired aquifer water mixing, hazardous soil subsidence, and the drying up of surface water bodies or springs. This brief paper highlights the key groundwater investigation procedures for more informed well siting and design to help mitigate against undesired environmental consequences. The subject has been discussed in recent literature, however this paper contributes practical insight based on the author’s real-world experience that may be valuable to the practitioner. The paper describes important procedures which should always be part of any water well project, regardless how much water is to be extracted. The paper addresses three issues critical to siting and designing wells: 1) the need for preliminary investigations and potential environmental impacts 2) the key experts that should be involved in these investigations; and 3) the core tasks of the hydrogeologist. Explanatory figures and references are given.
