英文摘要： Researches on interfacial tension and viscosity of CO2 and crude oil system have significant influence on exploring mechanism of CO2 sequestration and flooding, evaluating the potential of CO2 sequestration and building an integrity flow mechanism of CO2 and crude oil system. This project is going to conduct the following researches. Firstly, an experimental equipment and system should be developed to measure the density, interfacial tension and viscosity of multicomponent mixtures under reservior pressure. Secondly, interfacial tension and viscosity experiments should performed systematically for the mixture system between the CO2 and typical component of the crude oil including alkane, cyclo alkane, and aromatic hydrocarbon. Subsequently, the same experiment will also conducted on the CO2 and crude oil system. These work will replenish the shortage of the existing data. Lastly, based on the physcial properties, the relationship between crude oil and hydrocarbons should be constructed. After that a theoretical model of interfacial tension and viscocity for CO2 and crude oil system should be built. With the research of this project, the experimental data and prediction model of interfacial tension and viscosity for the CO2 and crude system should obtained, which provide the basis data and theoretical support
