| 摘 要： | 把特低渗透油藏岩心根据渗透率划分为不同等级,分别对不同等级岩心进行注水、注氮气和注二氧化碳室内实验.测得了不同开发方式条件下注采压差梯度和洗油效率,回归出不同开发方式下洗油效率随渗透率变化关系式,并对不同开发方式效果进行对比分析.研究结果表明:特低渗油藏在不同方式开发过程中,注入压力都表现为先上升后下降,最后趋于稳定值... |

| Abstract: | Ultra-low permeability reservoir cores were divided into different grades according to permeability,then laboratory experiments of different development methods were carried out by water flooding,nitrogen drive and carbon dioxide drive respectively according to different core grades.For different development methods,the pressure gradient and displacement efficiency were measured,the relationship between the displacement efficiency and the permeability was regressed,and the effect of different development me... |
| Keywords: | ultra-low permeability water flooding nitrogen drive carbon dioxide drive laboratory experiment |
