标准摘要
[中文适用范围]： 本文件适用于生产环境中的多相流计量，涵盖 custody transfer（交接计量）单相流计量点之前的上游环节，适用于陆上、海上或海下的分配计量。对于其他多相流计量应用，如油藏管理、试井和流动保障等，本标准可作为参考或指导文件使用。但本标准的重点在于对多相流计量精度有要求的分配计量系统应用。本文件引用了相关现有标准和推荐做法，以补充该领域的指导内容。文件阐述了多相流计量所采用的原理、多相计量的类型与分类、预期性能评估，以及多相计量系统的选型与操作。同时，文件还讨论了运行要求或限制，包括流量计验收期望、校准准则及流动特性等方面的内容。 [外文原描述]： Addresses multiphase flow measurement in the production environment, upstream of the custody transfer (single-phase) measurement point, where allocation measurement for onshore, offshore, or subsea is applied. For other multiphase flow measurement applications such as reservoir management, well tests, and flow assurance, the standard can be used as a reference or guide. However, the focus of this standard is on those applications where the accuracy of multiphase flow measurement for allocation systems is required. This document refers to existing standards and recommended practices to supplement the guidance it provides in this subject area. The document addresses principles used in multiphase flow measurement, multiphase metering types and classifications, assessment of expected performance, and selecting and operating multiphase measurement systems. Operational requirements or constraints are addressed, including expectations for flow meter acceptance, calibration criteria, flow loop
