| 摘 要： | CO2驱是提高油藏采收率的有效方法,制约其应用的主要因素有气源、腐蚀、安全以及环境保护等问题.自生CO2技术在一定程度上克服了对环境的负面影响和其它制约因素.实验结果表明,自生CO2技术适应性强,具有较好的驱油效果,采收率可提高10%左右. |
| 关 键 词： | 稠油油藏 自生CO2吞吐技术 降粘 膨胀驱油 提高采收率 |

| Abstract: | CO_2 flooding is considered an effective technology for improving oil recovery.The main factors which restrain the wide application of this technology are its dependence on natural CO_2 sources,corrosion of well,safety and environmental problems etc.The technology of in-situ generation of carbon dioxide eliminates its adverse impact on environment and other restricting factors.The results of experiments indicate that the technology of in-situ generation of carbon dioxide is effective,the oil recovery can be enhanced about 10%. |
| Keywords: | heavy oil reservoir in-situ generation of carbon dioxide viscosity reduction expansion oil displacement enhanced oil recovery |
