Standard Test Method for (Field Procedure) for Withdrawal and Injection Well Testing for Determining Hydraulic Properties of Aquifer Systems 测定含水层系统水力特性的抽注井试验(现场程序)的标准试验方法
发布日期: 2020-01-01
1.1 本试验方法涵盖了选择井位、控制变化(排放或注入)速率和测量水位的现场程序,用于分析含水层或含水层以及相邻围隔层的水力特性。 1.2 本试验方法与试验方法等分析程序结合使用 D4105/D4105M 或 D4106 评估数据并确定含水层特性。 1.3 按照指南中的说明选择适当的现场和分析程序 D4043号 . 1.4 限制- 该测试方法的局限性主要与该测试方法确定的现场情况与分析测试方法的简化假设之间的对应关系有关 D4105/D4105M 或 D4106 和 D4043号 . 1.5 单位- 以国际单位制表示的数值应视为标准值。以国际单位制以外的单位报告试验结果不应视为不符合本标准。 1.6 所有观察值和计算值应符合实践中确定的有效数字和舍入准则 D6026 . 1.6.1 本标准中用于规定如何收集/记录或计算数据的程序被视为行业标准。此外,它们代表了通常应保留的有效数字。使用的程序不考虑材料变化、获取数据的目的、特殊目的研究或用户目标的任何考虑因素;通常的做法是增加或减少报告数据的有效位数,以与这些考虑因素相称。考虑工程设计分析方法中使用的有效数字超出了本标准的范围。 1.7 该测试方法提供了一组用于执行一个或多个操作的指令。本文件不能取代教育或经验,应与专业判断结合使用。 并非本标准的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准,也不应在不考虑许多独特方面的情况下应用本文件。本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.8 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.9 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 在适当的水文地质现场,使用抽油井或注入油井测试现场程序和适当的分析程序,以确定含水层的透射率和蓄水系数以及封闭层的导水率。 5.2 实践 D3740 提供本测试方法中活动的评估因子。 注2: 本标准产生的结果的质量取决于执行该标准的人员的能力,以及所用设备和设施的适用性。符合实践标准的机构 D3740 通常认为能够胜任和客观的测试/采样/检查等。本标准的用户应注意遵守惯例 D3740 本身并不能保证可靠的结果。可靠的结果取决于许多因素;实践 D3740 提供了一种评估其中一些因素的方法。 5.3 由于该测试方法确定的现场情况与分析测试方法的简化假设之间的对应关系,该测试方法可能受到限制 D4105/D4105M 或 D4106 和 D4043号 .
1.1 This test method covers the field procedure for selecting well locations, controlling change (discharge or injection) rates, and measuring water levels used to analyze the hydraulic properties of an aquifer or aquifers and adjacent confining beds. 1.2 This test method is used in conjunction with an analytical procedure such as Test Methods D4105/D4105M or D4106 to evaluate the data and determine aquifer properties. 1.3 The appropriate field and analytical procedures are selected as described in Guide D4043 . 1.4 Limitations— The limitations of this test method are primarily related to the correspondence between the field situation determined by this test method and the simplifying assumptions of the analytical Test Methods D4105/D4105M or D4106 and D4043 . 1.5 Units— The values stated in SI units are to be regarded as standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard. 1.6 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 . 1.6.1 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 1.7 This test method offers a set of instructions for performing one or more operations. This document cannot replace education or experience and should be used in conjunction with professional judgement. Not all aspects of this standard may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a projects many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Withdrawal or injection well test field procedures are used with appropriate analytical procedures in appropriate hydrogeological sites to determine transmissivity and storage coefficient of aquifers and hydraulic conductivity of confining beds. 5.2 Practice D3740 provides evaluation factors for the activities in this test method. Note 2: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors. 5.3 This test method may be limited due to the correspondence between the field situation determined by this test method and the simplifying assumptions of the analytical Test Methods D4105/D4105M or D4106 and D4043 .
