Influence and Analysis of Fire Flooding Heavy Oil Development on the Realization of"Dual Carbon"Goal in Oilfields
Thermal recovery of heavy oil is the main source of carbon emission in oilfield production,and it is also an important link to achieve the goal of"dual carbon".Based on the current situation of fire flooding production and development,the impact of different heavy oil development methods on car-bon emission is studied by combining theoretical calculation of fire flooding flue gas with actual produc-tion.The analysis results show that among the three different heavy oil development methods,under the same air consumption,the CO2 emissions generated by fire flooding are the highest,while the CO2 emissions generated by gas boilers are the lowest.According to the actual production situation,at the same crude oil production rate,the CO2 emissions generated by fire flooding are the smallest.Rely-ing on the supporting technology of fire flooding flue gas reinjection can significantly reduce carbon emissions,and effectively improve heavy oil recovery rate.Continuous research and improvement of the fire flooding flue gas reinjection process is conducive to the promotion and application of the fire flooding development mode,and provides theoretical reference for the transformation of oilfield devel-opment to green and low-carbon.
