低渗透油藏注二氧化碳提高采收率的可行性研究

Study on Enhanced Oil Recovery in Low Permeability Reservoir

结合实际案例,对于低渗透油藏注二氧化碳提高采收率的可行性进行了探讨分析。提出一定的个人观点,指出现有注气技术中的环节重点,旨在保证注气驱动采收率提高。

Combined with practical cases,this paper discusses and analyzes how to improve oil recovery by gas injection in low permeability reservoir.Some personal viewpoints are put forward,some problems in the existing gas injection technology are pointed out,and then some strategies of innovative technology and new equipment technology are put forward in order to ensure the improvement of gas injection driven recovery.
