摘　　要：目前海上稠油热采主要利用燃油锅炉产生高干度蒸汽,锅炉燃烧后产生的烟道气含有CO_(2)以及其他组分,将烟道气处理并回注利用,不仅能提高油田采收率,还可减少碳排放。通过原油燃烧实验,测定燃烧产物中二氧化碳、二氧化硫、氮氧化物及粉尘的含量,在此基础上创新研发适用于海上油田燃油锅炉烟道气处理及回注的工艺和装备,将烟道气处理后随蒸汽注入稠油井中,实验表明蒸汽与气体同时注入可使周期产油量较只注蒸汽增大2~3倍,两者协同增效作用显著。相关装备已安装于渤海油田某稠油热采开发平台,后期将为海上稠油规模化热采提质增效及注热装备节能环保探索有效途径提供技术借鉴。At present,offshore heavy oil thermal recovery mainly uses oil-fired boilers to generate high-dryness steam.The flue gas generated after boiler combustion contains CO 2 and other components.The flue gas is treated and reinjected for use,which can not only improve oil recovery,but also reduce carbon emissions.Carried out the crude oil combustion experiment,explored the content of carbon dioxide,sulfur dioxide,nitrogen oxide and dust in the combustion products,and innovated and developed the process and equipment applicable to the flue gas treatment and reinjection of oil-fired boilers in offshore oil fields.After the flue gas treatment,it was injected into the heavy oil wells with steam.The experiment showed that the injection of steam and gas at the same time could increase the periodic oil production by 2 to 3 times compared with the injection of steam only,and the synergy between the two was significant.Relevant equipment has been installed on a heavy oil thermal recovery development platform in Bohai Oilfield,which will provide technical reference for the exploration of effective ways to improve quality and efficiency of large-scale thermal recovery of offshore heavy oil and energy conservation and environmental protection of thermal injection equipment.
