目前CO2泡沫体系性能改善的方法包括：①表面活性剂分子结构优化，包括加强亲水基团、优化疏水基团和引入亲CO2基团；②表面活性剂复配协同，包括阴/非离子表面活性剂复配、阴/两性离子表面活性剂复配和非/两性离子表面活性剂复配；③聚合物提高基液黏度，改善液膜黏弹性；④纳米颗粒改善泡沫气/液界面性质。本文就以上方面展开综述，介绍了研究进展、作用机制和存在问题，并对下一步研究进行了展望。参60

At present，the research on the performance improvement method of CO2 foam system is mainly focused on the following aspects：①Optimization of the surfactant molecular structure，including the strengthening of the hydrophilic group，the optimization of the hydrophobic group and the introduction of the pro-CO2 group；②Combination of surfactant，including anionic/ nonionic surfactants，anionic/amphiprotic surfactants and nonionic/amphiprotic surfactants；③Improving the viscosity of the base fluid and the viscoelasticity of liquid film by polymer；④Using the nanoparticles to improve the gas/liquid interface properties of the foam. In this paper，the progress of research，the mechanism and the existing problems was introduced，and the research direction in the future was looked forward.
