【摘要】 随着CO2强化采油技术（CO2-EOR）在国内原油开采领域地逐步推广,我们需要面对并解决原油溶CO2引起油品性质改变所带来的各方面问题。由于CO2在原油体系中具有较高的溶解性,在注CO2开采后,原油体系内将混溶烃类气体及大量CO2,从而对体系的流变性产生巨大影响。本研究以长庆含蜡原油为研究对象,通过实验测试气体溶解度、油品溶胀程度、体系粘温关系与体系低温胶凝结构强度的变化,分析CO2与CH4对于长庆原油流变性的影响规律。
【Abstract】 As sequestration of CO2 in enhanced oil recovery applications gets its popular in China, there are more and more problems we should face and solve, which is caused by changes of oil properties. By reason of the high solubility of CO2 in crude oil system, the rheology behavior of live oil vary after CO2 injection exploitation. In this study, Changqing crude oil is analysed by testing gas solubility, swelling degree, viscosity-temperature characteristics and yield value. It is conducive to reveal the mechanism of CO2 gas mixture on crude oil rheology.
