摘　　要：针对胜坨油田二区 9- 1 0单元的层间非均质和平面非均质性 ,运用水动力学方法 ,采用周期注水及增压注水改善单元的水驱油效果。经过 6a的实施 ,单元的开发形势趋好 ,单元采收率提高 9 6 2 % ,增加可采储量 3 4 1 5kt,对同类型非均质性油藏改善水驱油效果 。Based on the exploitable condition of unit 9-10 in second zone of Shengtou Oilfield,the oil reservoir production feature is analyzed. Aimming at plane and interlayer anisotropism of the unit,and combining with the principle of hydrodynamics,the effect of water displacing oil has been improved by periodic and supercharge water injection.During 5 years operation,the dynamic production condition is getting better in this unit.Daily crude output is higher than past.The recovery efficiency in this unit has improved by 9.62%.The exploitable reserve has increased 341,500 tons.For the same type of anisotropism oil reservoir,this method is valuable for improving the effect of water displacing oil and enhancing the final oil recovery efficiency.
