1.1 本规程描述了创建相关性的程序步骤，该相关性可用于比较动态成像分析仪（分析仪）和规定筛组之间支撑剂粒度分布的结果。 1.2 本规范中包含的支撑剂尺寸和分布规范列于API标准19C（API 19C）中，如 表1 然而，随着行业的发展，可能会使用其他规范，这种做法也可以与这些规范一起使用。 1.3 本规程可能不适用于所有支撑剂类型和名称。所确定的相关性的可接受性由操作员判断。 1.4 以国际单位制表示的值应视为标准值，但根据惯例，通常使用“替代”系统识别筛目名称 第11页 ，例如3英寸。和200号而不是75号的“标准”系统 mm和75µm。 1.5 观察值和计算值应符合实践中确立的有效数字和舍入指南 D6026型 ，除非被本标准取代。 1.5.1 用于规定在实践中如何收集/记录和计算数据的程序 D6026型 被视为行业标准。此外，它们代表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，以符合这些考虑。 考虑工程数据分析方法中使用的有效数字超出了这些测试方法的范围。 1.6 本实践提供了一组用于执行一个或多个特定操作的说明。本文件不能代替教育或经验，应结合专业判断使用。并非本实践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判断给定专业服务是否充分的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。 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。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 通过将分析仪的结果与筛组相关联，可以使用非筛方法，从而得出相互可比的结果。 5.2 使用分析仪测量支撑剂有助于提供颗粒形状特征，这对这些材料的性能很重要。目前，形状分析由操作员根据API 19C对少量颗粒的目视观察进行确定。 来自许多颗粒成像分析的可用信息可用于评估支撑剂形状特征，而不是仅少量。

1.1 This practice describes procedural steps to create a correlation that can be used to compare results of proppant size distributions between dynamic imaging analyzers (analyzers) and prescribed sieve sets. 1.2 The proppant size and distribution specifications that are included in this practice are listed in API Standard 19C (API 19C) and shown in Table 1 , however as industry evolves additional specifications may come into use and this practice can be used with those as well. 1.3 This practice may not be applicable to all proppant types and designations. The acceptability of the correlations determined are judged by the operator. 1.4 The values stated in SI units are to be regarded as the standard, except sieve designations are typically identified using the ‘alternative’ system in accordance with Practice E11 , such as 3 in. and No. 200 instead of the ‘standard’ system of 75 mm and 75 µm, respectively. 1.5 Observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 , unless superseded by this standard. 1.5.1 The procedures used to specify how data are collected/recorded and calculated in Practice D6026 are regarded as the industry standard.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 these test methods to consider significant digits used in analysis methods for engineering data. 1.6 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice 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 project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process. 1.7 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. 1.8 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 The ability to correlate results of analyzers to sieve sets enables the use of non-sieve methods to be employed that give comparable results to each other. 5.2 The use of analyzers for proppant measurement has the benefit of providing particle shape characteristics which are important in the performance of these materials. Shape analysis is currently done by operator’s determination based on a visual observation of a small number of particles per API 19C. Available information from imaging analysis of many particles can be used to assess the proppant shape characteristics as opposed to just a small number.
