摘　　要：CCUS/CCS是全球油气行业绿色低碳转型发展的共同战略选择,开展碳减排量核算评估对CCUS项目建设和决策具有重要参考意义。按照《中国石油天然气生产企业温室气体排放核算方法与报告指南(试行)》要求,分析某CCUS示范区块现状,针对CCUS项目全链条工艺流程中CO_(2)的捕集、管道运输、驱油、埋存各阶段,确定核算边界,识别排放源,提出CO_(2)排放监测方案、计算公式和核算方法。依据项目运行中各环节用能消耗、工艺碳排放、泄漏点监测等,通过工程可研报告中的数据对减排量进行计算,得出在不考虑CO_(2)放空、逸散的情况下,CCUS示范工程投产后首年CO_(2)减排量为60.2×10^(4)t,为CCUS碳资产开发提供数据支撑。CCUS/CCS is a common strategic option made by the global oil and gas industry for green and low-carbon transitional development.Evaluation on accounting reduction of carbon emission is of important reference to construction and making decisions on the CCUS projects.Based on the requirements of“Method for accounting greenhouse gases emission and report guide for China’s oil and natural gas production enterprises(trial)”,this article analyzes the present conditions of a certain CCUS demonstration block.Focusing on the various stages of the CCUS project-CO_(2) capture,piped transmission,oil flooding and burial-as well as determination of the accounting boundaries and identification of emission sources,the article also puts forward the monitoring plan,calculation formula and accounting method for CO_(2) emission.Based on energy consumption,carbon emission from the process and monitoring of leaking spots in operation of the project and calculation of emission reduction according to the data from the engineering feasibility study and under the condition that venting and dissipation of CO_(2) are not taken into account,reduction of CO_(2) emission is estimated at 60.2×10^(4) tons in the first year after the CCUS demonstration project is put into production,thus providing data support for CCUS carbon asset development.
