摘　　要：分析北部湾油田的地质情况后认为注入CO2气体可提高原油采收率。通过筛选论证,将东方1-1气田在海南岛陆上终端分离出的CO2注入北部湾的C油田,CO2日分离量1 000 t时,正好能满足油田驱油需要的注入量,可实现20年的稳定注入。虽然180 km的管线费用较大,但是驱油提高的采收率产生的效益更大,不仅能覆盖前期所有的投入,还能有不少获利,如果计算碳税或者碳交易的一些收入,CO2驱油的前景更加光明,具有很好的经济、环保及社会效益。By screening and assessment,the C oil field located in Beibu Gulf is chosen as the place for EOR to inject the CO2 discharged from the terminal of gas field in Hainan Island.According to the oilfield conditions,when the rate of injected CO2 reaches 1 000 t/d,it is just accordant with the requirement of stable CO2 injection for 20 years.Although paving 180 km pipeline is expensive,the benefit from EOR by CO2 injection process will be greater,not only offsetting the cost invested at the early stage,but also gaining a lot of profit.If carbon tax and carbon trade are implemented in China,the CO2 injection process for EOR will be more promising.
