摘　　要：为了改善特高含水期深部调剖的实施效果,运用数值模拟技术开展了调剖和后续的水驱调整组合增效的研究。调剖后,主流线或者非主流线油井单方向适度提液能够增强调剖扩大波及体积的能力,提升深部调剖效果,而且非主流线提液效果更好。主次流线油井均提液或者水井提高注入量对调剖效果不利。建议调剖后尽量保持主流线油井的液量不变,在非主流线方向适度提液20%左右。该技术在胜利油田的成功应用,对特高含水期深部调剖提高采收率技术具有一定的参考价值。In order to improve the effect of deep profile control in high water-cut stage, the effects of the deep profile control and the subsequent water flooding are studied using reservoir numerical simulation. It is shown that after deep profile control, the appropriate increase of the flow velocity of single oil well in main flow line or secondary flow line can increases the swept volume and the effect of deep profile control, and the improving effect of increasing the flow velocity of oil well in secondary flow line is better than that in main flow line; the increase of the flow velocity of all oil wells in main flow line or the increase of the injection amount of water wells are all not favorable to the improvement of deep profile control effect. So it is suggested that after deep profile control, the flow velocity of the oil wells in main flow line is not changed, the flow velocity of the oil wells in non-main flow lines is increased by 20%. The result is successfully applied to Shengli Oilfield, the recovery factor of the oilfield in high water-cut stage is enhanced.
