摘　　要：中国石油开采技术不断升级,但石油储存量也在不断降低,一些长期开采的油田的开采难度不断升高,在低渗油藏中采用新型采油技术进行驱油、采收能够有效保证油田生产效率,进一步优化石油油藏的开采利用效果。二氧化碳驱油工艺是利用二氧化碳加压及降低原油黏度从而驱油、开采的一种技术手段,在实际应用中由于二氧化碳不助燃且性能较为稳定,具有较高的安全性,因此具有一定的推广应用价值。文章就二氧化碳驱油技术的机理及效果、问题及未来发展等情况进行了探讨。With the continuous upgrading of China’s oil production technology and the continuous reduction of oil reserves,the diff iculty of exploitation of some long-term oilf ields is also increasing.Only by adopting new oil production technology for oil displacement and recovery in low-permeability reservoirs can we effectively ensure the production eff iciency of oilf ields and further optimize the exploitation and utilization effect of oil reservoirs.Carbon dioxide oil displacement technology is a technical means of oil displacement and production by using carbon dioxide to pressurize and reduce the viscosity of crude oil.In practical application,because carbon dioxide does not support combustion and has stable performance,it has high safety,so it has a certain popularization and application value.This paper discusses the mechanism,effect,problems and future development of CO_(2) flooding technology.
