摘要
稠油热采是油田生产过程中碳排放的主要来源,也是影响实现"双碳"目标的重要环节.针对火驱生产开发现状,通过将火驱烟道气理论计算与实际生产相结合,研究了不同稠油开发方式对碳排放量的影响,分析结果表明:在三种不同稠油开发方式中,同一空气消耗量下,火驱产生的CO2 的排放量最大,燃气锅炉产生的CO2 的排放量最小;根据实际生产状况,在同一原油产量下,火驱产生的CO2 的排放量最小.依靠火驱烟道气回注地面配套工艺能显著降低碳排放量,有效提高稠油采收率.持续研究完善火驱烟道气回注工艺,有利于火驱开发方式的推广运用,为油田开发向绿色低碳转型提供理论参考.
Abstract
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.
