摘　　要：油气田拥有丰富的压力能资源,开发利用天然气余压发电项目潜力较大,由于当前技术和装备仍不够成熟,影响了余压发电项目的规模效益开发,迫切需要通过碳资产开发来提升项目的经济性。为了推动天然气余压发电产业的健康可持续发展,助力油气田企业如期实现“双碳”目标和新能源业务规模效益发展,对油气田余压发电项目碳资产开发进行了可行性评估,测算了碳资产开发对天然气余压发电项目收益的影响,分析了项目碳资产开发的可行性。研究结果表明:(1)参考当前碳市场价格,天然气余压发电的单位装机年减排收益达到188元/kWh,远高于陆上风电和光伏项目,但其单位投资年减排收益低于陆上风电项目,与光伏项目基本持平;(2)从方法学、额外性、监测可行性、减排量及收益评估等四个方面论证了余压发电项目碳资产开发的可行性;(3)天然气余压发电项目碳资产开发及监测管理在技术角度不存在困难,但因项目规模较小,单个项目开发收益不具经济可行性,可采取多个项目可研方案整体设计,碳资产捆绑开发;(4)通过特殊类型项目开发规则完善、建立适合我国“双碳”工作发展策略的正面技术清单、采用数字化管理方式提升开发效率、碳金融工具的应用等4方面举措来推动余压发电碳资产开发。Oil&gas fields are rich in pressure energy resources and have great potential to develop and utilize waste natural pressure gas for power generation.The current technologies and equipment are still not mature enough,which impacts the large-scale benefit development of waste pressure power generation project,so it is in urgent need to improve the economy of the project through carbon asset development.In order to promote the healthy and sustainable development of the waste natural gas pressure power generation industry and help oil&gasfield enterprises achieve the"dual carbon"goal as scheduled and the large-scale benefit development of new energy business,this paper evaluates the feasibility of the carbon asset development of the oil&gasfield’s waste pressure power generation project,measures the impact of carbon asset development on the income of waste natural gas pressure power generation project,and analyzes the feasibility of the carbon asset development of the project.And the following research results are obtained.First,referring to the current carbon market price,the annual emission reduction income per unit installed capacity of waste natural gas pressure power generation is 188 yuan/kWh,which is much higher than that of onshore wind power and photovoltaic project,but the annual emission reduction income per unit investment is lower than that of onshore wind power project and basically the same as that of photovoltaic projects.Second,the feasibility of carbon asset development of waste pressure power generation project is demonstrated from the aspects of methodology,additionality,monitoring feasibility,emission reduction and income evaluation.Third,there is no technical difficulty in carbon asset development and monitoring management of waste natural gas pressure power generation project,but due to the small scale of the project,the development income of a single project is not economically feasible.It is suggested to design multiple project feasibility schemes as a whole and perform bundled development
