摘要: 利用经典的水驱特征曲线公式推导了广义水驱特征曲线公式。广义水驱特征曲线既可以对应多条累积产油量与含水率关系的水驱特征曲线,又可以反映水驱油田不同的含水上升规律,可用于描述及预测水驱油田含水率的变化、双积水油比的变化以及计算可采储量,尤其是计算逐年的可采储量,因而有较高的理论及实际应用价值。

Abstract: The generalized water displacement curve formula derived from the classical one can correspond to many relations between cumulative oil production and water cut, reflect the different water cut trends in the waterdrive oilfields, describe and predict the changes in water cut and cumulative water-oil-ratio, and calculate the recoverble reserves, especially the ones in successive years. So it possesses higher theoretical and pratical values.
