进入冬四九，鄂尔多斯盆地部分地区气温跌至-20℃，凛冽寒风中，中国石油长庆油田天然气生产现场 却是一派火热景象——日产天然气超1.7亿立方米，源源不断地输往京津冀、陕甘宁等地区的50多个大 中城市。 据测算，这一日产气量可等效替代标煤20余万吨，减排二氧化碳约24万吨，在守护万家温暖的同时， 为"双碳"目标推进注入了强劲的绿色动力。 在我国推进碳达峰、碳中和的过程中，天然气已成为当前时期增长更快、更现实的绿色能源。作为中国 陆上天然气管网枢纽中心，长庆油田始终锚定绿色发展方向，将环保理念融入气田开发全流程，构建 起"源头减排、过程控污、末端利用"的全链条绿色保供体系。 在源头管控上，长庆油田推广大平台集约布井技术，精准避开地面水源区、林缘区等环境敏感地带，对 部分敏感区域的天然气井实施封堵保护；钻井泥浆和压裂液循环利用技术的普及，搭配"开发一片、保 护一片、绿化一片"的植被恢复行动，让气田与周边生态和谐共生。 生产过程中，节能减排技术的落地见效让绿色底色愈发鲜明。产品天然气冷量回收、凝析油稳定余热利 用等技术的应用，每年可节约天然气6000万立方米以上、节约用水8万吨，实现了生产效能与环保效益 的同步提升。 ...

Core Viewpoint - The article discusses the implementation of a new methodology for voluntary greenhouse gas emission reduction projects in the context of low gas recovery from onshore oil fields, aiming to enhance methane recovery, reduce carbon emissions, and promote the green transition of the oil extraction industry in China [4][5]. Summary by Sections Background - The methodology was jointly issued by the Ministry of Ecology and Environment and the National Energy Administration on November 21, 2025, to encourage broader industry participation in greenhouse gas emission reduction [4]. Principles of Methodology - **Scientific Principle**: The emission reduction mechanism must be scientifically sound and comply with industry technical standards [7]. - **Operability Principle**: The methodology should simplify monitoring parameters while ensuring data is verifiable and traceable [9]. - **Conservativeness Principle**: Emission reductions should be conservatively estimated to avoid overestimation [10]. - **Sustainable Development Principle**: Projects must align with sustainable development goals and not negatively impact the environment or socio-economic development [11]. Applicable Conditions - The methodology applies to low gas recovery projects from onshore oil fields, requiring specific conditions such as a processing capacity of at least 30,000 Nm³/d and compliance with national laws and industry policies [14][15]. Project Duration and Baseline Scenario - The project duration for emission reduction claims can last up to 10 years, with a baseline scenario established for comparison [17]. Additionality Demonstration - The projects face challenges such as complex gas composition, remote locations, and high investment costs, which necessitate additionality proof for the emission reduction claims [19][20]. Emission Reduction Calculation - Emission reductions are calculated based on the replacement of newly extracted natural gas with recovered gas, considering various emission sources [21][22]. Data Management Requirements - A robust data management system must be established, including monitoring, recording, and cross-verifying data, with a retention period of at least 10 years for all project-related data [25]. Verification and Public Oversight - Verification of emission reductions will be conducted by designated institutions, with monitoring data made publicly available through local ecological departments [27][30].
