摘要
本论文用岩心驱替装置对四种类型岩心进行水驱油实验和二氧化碳驱油实验。结果表明:渗透率相对低的岩心注CO2比水驱能提高采收率20%左右且注入压力比水驱油低很多。
In this paper, the four kinds of core were carried on water flooding experiment and carbon dioxide flooding experiment with the core displacement device. The results showed that： carbon dioxide flooding can enhance oil recovery about 20% and the injection pressure is much lower than water flooding in relatively low permeability core.
