PI调剖决策技术在蒙古林砂岩油藏的应用

THE APPLICATION OF PRESSURE INDEX(PI) CONTROL TECHNOLOGY IN MENGGULIN SAND STONE RESERVOIR

蒙古林砂岩油藏油层薄，主力层单一，层间调整的余地小，油层平面矛盾突出。调剖是该油藏的一项主要的控水稳油手段。1995年引入了；%PI；%调剖决策技术，科学地指导了该油藏的控水工作，使得油藏的稳产期延长，保证了该油藏的持续高效开发。截至1999年底，共实施11轮计279井次的粘土调剖措施，累计增油达10.89×104t，施工单井次增油390t，减少产水35.6×104m3，取得了明显的降水增油效果；.

The oil reservoir of Menggulin Oilfield is thinner, so the main productive zone is single and interlayer adjusting is impossible. That made the contradiction of plane in oil reservoir stressly. Profile control is one of the major measures in water controlling and high and stable yields. The Pressure index control technique, which was recommended in 1995, guided the reservoir′s water control work scientifically. This made the stable production period elongation and ensured the reservoir to produce sustain and valid. Till 1999, the profile control measures were implemented 11 cycle, 279 wells, which cumulative production oil 10.89×104t, each well 390t, and producing water reduced 35.6×104m3. The effect of cumulative production and water reduced was obvious.;
