CO foam injection has been shown to be effective under reservoir conditions for enhanced oil recovery. However, its application requires a certain stability and surfactant absorbability on rock surface, and it is also associated with borehole corrosion in the presence of water. Adding surfactants to CO can enhance the interaction between CO and crude oil and control the CO mobility, thereby improving the performance of CO flooding. This paper presents a review of the research of CO-soluble surfactants and their applications. Molecular dynamics simulation is introduced as a tool for analyzing the behavior of the surfactants in supercritical CO (scCO). The applications of CO-soluble surfactants, including CO thickening, reducing miscibility pressure, and generating supercritical CO foam, are discussed in detail. Moreover, some opportunities for the research and development of CO-soluble surfactants are proposed.
在油藏条件下，注入CO泡沫已被证明对提高采收率有效。然而，其应用需要在岩石表面具有一定的稳定性和表面活性剂吸附性，并且在有水存在的情况下还与井筒腐蚀有关。向CO中添加表面活性剂可以增强CO与原油之间的相互作用并控制CO的流动性，从而提高CO驱油的性能。本文综述了CO可溶表面活性剂的研究及其应用。介绍了分子动力学模拟作为分析表面活性剂在超临界CO（scCO）中行为的工具。详细讨论了CO可溶表面活性剂的应用，包括CO增稠、降低混相压力和生成超临界CO泡沫。此外，还提出了一些CO可溶表面活性剂的研发机会。
