随着油田三次开采的深入与碳捕集封存技术的发展，CO2注入成为提高采收率与缓解温室气体效应的有效手段，针对气源地与注入地差异问题，管道输送以输量大、输送距离远、经济性好等优点成为 CO2输送的最重要途径。通过对国内外 CO2管道输送技术的研究，针对四种管输状态（即超临界输送、密相输送、液态输送、气态输送）的不同特点，得出管输中超临界输送与密相输送是较为合理的输送方式，并分析了输送过程中遇到的关键技术问题，为国内 CO2管道输送的开展提供技术支撑。

With in-depth study of the thir d oil field exploration and the development of carbon capture sequestration technology, CO2 injection becomes the effective means of enhancing oil recovery and reducing greenhouse effect. Aiming at the problem of long distance between gas source site and injection site, the pipeline transportation becomes the most important way of transporting carbon dioxide because of its advantages of huge throughput, long transmission distance and well economical efficiency. In this paper, through research on the CO2 pipeline transportation technology at home and abroad, characteristics of four pipeline transportation ways (supercritical transportation, dense phase transportation, liquid phase transportation and gas phase transportation) were analyzed. It’s pointed out that supercritical transportation and dense phase transportation are more reasonable. At last, the key technical problems in the transportation process were studied, which could provide technical support for the development of carbon dioxide pipeline transportation in China.
