摘要
由长岩心实验、微观实验以及细管实验结果,认识到了一些新的重要的CO2驱油化学机理:萃取原油中碳轻质化学成分、萃取后混相以及水气交替驱时水对混相影响机理,这些机理的认识对油田二氧化碳驱油应用具有指导意义。
There are a series of experiment researches about CO2 oil displacing in the microcosmic and long cores test, component change of carbon in oil from tubule experiment. Based on these tests, some important chemical mechanisms on the craft mode of CO2 flooding and the water alternate gas injection are recognized. These mechanisms, including the effect of water on CO2 miscible flooding and miscible after extraction light C composition, offer good reference to studies of CO2 flooding in oil reservoir and laboratory.
