摘　　要：油田经长期注水开发 ,影响了油田的水驱采收率。通过多年调剖试验 ,总结出“区块整体调剖压力指数 (PI)决策技术” ,应用于濮城油田西区沙二上2 +3层系的调剖井 ,在 2 1口油井中见到增油效果。文中介绍PI决策技术的理论基础及用途 ,以及操作方法 ,评价了PI决策技术在该层系调剖井获得的效果。For prolonged waterflood development in Pucheng Oilfield,water drive recovery factor of Oilfield is affected.Through profile control testing in many years,PI decision technique is summarized.Based on application of PI decision technique in 21 wells in the upper ES2 2+3 West Area of Pucheng Oilfield,the results show the stimulation effect is obvious.The paper presents theoretical basis,application and operational method of PI decision technique.Meanwhile,the application effect of PI decision technique in profile control well is evaluated.
