摘要
研究了油水两相渗流时油的分流量随可流动含油饱和度的变化规律，证明两者可用方程表述。结合前沿推进理论，推导出了一种新的采收率预测方程。应用该方程对国内外6个油田的采收率进行了预测，证明该方法具有较强的实用性，既可用于油藏早期评价阶段，也可用于中高含水开发阶段。
Rules of changes of fractional flow of oil at two phase flow with mobile oil saturation are studied, proving that they can be expressed with equation . Combing the front advancing theory, a new equation for recovery factor prediction isas derived. Recovery factors of 6 oilfields at home and abroad are predicted with this equation, proving that this method has much practicability, and it can be not only used for early evaluation stage of reservoirs but also for development stage with medium and high water cut.
