摘要 全球变暖日益引起各国关注,CO2 (Carbon dioxide)被认为是最主要的温室气体,我国已向国际社会做出了"双碳"庄严承诺。CO2-EOR (CO2 enhanced oil recovery)技术将捕集来的CO2注入油藏中不仅可以使原油膨胀,降低原油黏度,增强原油流动性从而提升驱油效率,同时还可以减少CO2排放,具有非常重要的战略价值。因此,研究CO2膨胀液体(CO2-expanded liquids, CXLs)的机理及其传递特性对于CO2-EOR技术的利用具有重要意义。从实验设备、实验数据以及计算模型3个方面综述了CO2-EOR技术中涉及的CO2膨胀液体黏度的发展现状,并对其发展趋势进行归纳。在实验设备方面,表面光散射等非接触式黏度测量方法越来越受到关注;在实验数据研究方面,CO2-正癸烷、CO2-正十四烷二元体系数据较为丰富,而CO2-正构烷烃多元体系、CO2-环烷烃、CO2-芳香烃及CO2-助溶剂体系的数据还比较欠缺;在计算模型方面,综述了适用于CO2-膨胀液体黏度的Eyring半理论模型的基本原理和研究进展,对不同类型的模型计算精度进行了综合比较。

Abstract: The global warming issue caused by the greenhouse effect has attracted much attention over the past few years. Carbon dioxide (CO2) is considered the most important greenhouse gas. China has committed to the international community to reach carbon peaking and carbon neutrality goals. The CO2-EOR (CO2 enhanced oil recovery) technology can not only reduce CO2 emissions, but also expand the crude oil, reduce the viscosity of the crude oil, and enhance the fluidity of the crude oil to improve the oil recovery efficiency. Therefore, a full understanding of the transfer characteristics of CO2-expanded liquids (CXLs) is very important for the utilization of CO2-EOR technology. This paper provides a literature review of the research on the viscosity of carbon dioxide expanded liquids systems, including the experiment equipment, experimental data, and calculation models. The non-contact viscosity measurement methods such as surface light scattering have recently attracted more attention. And, there were many available experimental data for the CO2-n-decane and CO2-n-tetradecane binary systems while few data for CO2-n-alkane multi-system, CO2-cycloalkane, CO2-aromatic hydrocarbon, and CO2-cosolvent systems. This paper also describes the use of Eyring’s absolute reaction theory for calculating the viscosity of CXLs.
