residual equation

The results show that static residual oil saturation can be obtained by time-average equation and on the contrary dynamic residual oil saturation ( the change rate of saturation) can be gained through integrated time-average equation with time migration seismic technique.

结果表明，由时间平均方程可以求得静态剩余油饱和度；将时间平均方程与时移地震相结合，可以获得动态剩余油饱和度（饱和度的变化率）。

With the help of time-average equation and4D ( time migration) seismic technique, residual oil distribution predicting method is developed.

采用时间平均方程和时移地震技术，得出了预测剩余油分布的方法。
