东北地区在新中国成立之际，陆续发现几个大规模油藏构造，为新中国建设作出了贡献，目前产量下降，勘探进展缓慢，只有通过提高采收率延长油田寿命。油田工作者，通过各种物理化学方法，去探究提高采收率机理，在经过数值模拟，室内实验等必要过程，在矿场应用效果良好。分层注水，科学安排井间距离，有效保护地层，提高产能。论述了目前采收率现状，提出合理化建议，作用生产，提高采收率。

When the founding of new China, several large-scale reservoir structures were found in the northeast of China, which contributed to the construction of the new China. Now these reservoirs’ output declines, the exploration progress is slow, these reservoirs’ life is only prolonged by improving the oil recovery rate. The mechanism of enhanced oil recovery has been explored through various physical and chemical methods; after the numerical simulation and laboratory experiments, good application effect has been obtained. It’s pointed out that separate-layer water injection and scientific arrangement of inter-well distance can effectively protect the formation to improve the productivity. In this paper, the current situation of oil recovery was introduced; reasonable suggestions were put forward to improve oil recovery.
