自2019年5月24日中国国家发展和改革委员会等四部委共同发布《油气管网设施公平开放监管办法》以来,中国天然气贸易交接计价方式实现了由体积向能量的正式转变，但在具体开展的能量计量工作中,标准、法制、关键技术等方面尚存在诸多问题。在对国内外天然气能量计量法规、标准及关键技术充分调研的基础上,分析了规范、标准的适用性。分析结果表明，中国开展天然气能量计量技术已成熟,从工艺流程方案、流量计及配套设备仪表选型、站场改造方案等角度提出了开展天然气能量计量改造的关键设计问题,为能量计量的研究及设计工作提供技术支持。
TheRegulations on the Fair Opening of Oil and Gas Pipeline Network Facilitieswas jointly issued by China NDRC( National Development and Reform Commission ), National Energy Administration, Ministry of Housing and Urban-Rural Development and State Administration for Market Regulation on May 24 2019. It marked the milestone change in the pricing of natural gas in China from volume basis to energy basis. Aiming at the existing problems and research status of developing natural gas energy metering in China, this paper analyzes the applicability of standards and specifications of energy metering based on the study of relevant domestic and international laws, standards and key technologies of natural gas energy metering. The result shows that the technologies of natural gas energy metering in China are sufficiently matured. The key design approach for natural gas energy metering is proposed from the analysis on the aspects of process flow scheme, the selection of flowmeter and associated equipment, and the modification of existing metering station. This key design approach provides technical support for further work on energy metering research and design.
