摘　　要：介绍了压力指数(PI)值的计算、修正以及决策因子的计算.着重阐述了PI决策技术的原理和应用方法。在胜利油田4个区块的整体调剖期间,应用PI决策技术在274口注水井中,有针对性地选取了74口水井进行调剖,对实施情况及应用效果进行了分析。实施PI决策技术后,综合递减率由15.02％下降为1.47％,含水上升率由0.72％下降为0.10％,采收率增加3.8％,降水增油效果明显。This paper introduced the calculations of pressure index (PI), amendment and decision factors, and particularly described the principle and application method of PI decision technology. During profile controlling in four areas in Shengli oilfield, PI decision technology was used and application analysis was made by choosing 74 wells from 274 wells to make profile controlling. After using PI decision technology, the composite declining rate decreased to 1.47% from 15.02 %, water-cut escalating rate dropped to 0.10% from 0.72%, and recovery efficiency increased 3.8%, the effect of reducing water and increasing oil was very obvious.
