油气田企业碳资产开发重点方向及路径研究

Study on key direction and path of carbon asset development of oil&gasfield enterprises

在“碳达峰、碳中和”背景下,碳资产开发是提升节能减排及新能源项目经济效益的重要手段,有利于油气田企业按期实现碳达峰以及新能源业务规模效益发展。为了加快油气田企业绿色低碳转型发展,助力实现“双碳”目标,对国内外碳资产开发体系进行了系统梳理,分析了油气田企业碳资产开发的重点方向,提出了碳资产的开发路径。研究结果表明:(1)油气田企业碳资产开发重点方向主要集中于甲烷减排和回收利用、余热余压利用、可再生能源/新能源利用以及二氧化碳捕集利用和封存(CCUS)等类型项目;(2)大型风光电等并网可再生能源类型项目可筹备申请国家CCER,不上网的小型分布式光伏、地热源利用等可再生能源类型项目,以及余热余压等自用项目,伴生气回收、逸散甲烷回收等油气田自身减排类型项目可以同步考虑UER项目和VCS项目;(3)油气田伴生气回收利用类项目,目前只有针对油田的减排方法学,气矿类项目需要做适当优化,余压余热利用、可再生能源和新能源利用的减排机制及方法学已经非常成熟,CCUS建议联合第三方开发新的方法学;(4)建议油气田企业提前摸底企业碳资产可开发资源,建立专业的碳资产开发管理团队,因地制宜及时启动减排项目开发。

Under the background of"carbon peaking and carbon neutrality",carbon asset development is an important means to improve the energy conservation&emission reduction and the economic benefits of new energy projects,and it helps oil&gasfield enterprises achieve carbon peaking and large-scale benefit development of new energy business on schedule.In order to speed up the green and low-carbon transformation and development of oil&gasfield enterprises and assist the achievement of the"dual carbon"goal,this paper systematically sorts out domestic and foreign carbon asset development systems,analyzes key directions of carbon asset development of oil&gasfield enterprises,and proposes development paths of carbon asset.And the following research results are obtained.First,the carbon asset development of oil&gasfield enterprises mainly focuses on methane emission reduction and recycling,waste heat and pressure utilization,renewable energy/new energy utilization,and CO_(2)capture,utilization and storage(CCUS)projects.Second,large-scale grid connected renewable energy projects(such as wind and solar power)can be prepared to apply for national CCER,while small-scale distributed photovoltaic,geothermal energy utilization and other renewable energy projects that are not connected to the grid,as well as self use projects(such as waste heat and pressure)and oil&gasfield emission reduction projects(such as associated gas recovery and escaping methane recovery)can apply for UER projects and VCS projects simultaneously.Third,as for the associated gas recovery and utilization projects of oil&gasfields,there is only the emission reduction methodology for oil fields.Gas mining projects need to be properly optimized.The emission reduction mechanisms and methodologies of waste pressure and heat utilization and renewable energy/new energy utilization have been well developed.As for CCUS,it is suggested to cooperate with the third party to develop new methodologies.Fourth,It is recommended that oil&gasfield enterprises figure out their exploitable resources of carbon assets in advance,establish a professional carbon asset development management team,and start the development of emission reduction projects in time according to local conditions.
