摘要
陆相复杂非均质油藏高含水期剩余油分布特征是总体分散、局部集中,主要受油藏分割性控制,仍存在较多的剩余油富集区。揭示了剩余油富集区形成机理,建立了断层分割控油、夹层分割控油和优势渗流通道控油等3种主要控油模式,阐明了其对剩余油富集区形成和分布的控制作用,并形成了低级序断层预测、夹层定量预测、优势渗流通道预测等油藏分割性预测技术,在胜利油区应用取得良好效果。
The remaining oil in heterogeneous continental reservoirs at high water-cut stage is generally dispersed with accumulation in certain areas, controlled by reservoir compartmentation. Reservoir compartmentation models caused by fault, interbed and preferential flowing path are put forward, their control on remaining oil accumulation and distribution is expounded and the mechanism of remaining oil accumulation is revealed. Technologies for prediction of low-grade fault, interbed and preferential flowing path are developed, whose application in Shengli Oilfield is effective.
