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-CO2 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 CO2 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 CO2 are not taken into account,reduction of CO2 emission is estimated at 60.2×104 tons in the first year after the CCUS demonstration project is put into production,thus providing data support for CCUS carbon asset development.
