摘要： 水驱体积波及系数定义为：天然水驱或人工注水占有的体积与含油孔隙体积之比。水驱体积波及系数是判断水驱开发效果、进行开发调整和提高采收率的重要依据。由丙型和丁型水驱曲线提供的预测水驱体积波及系数的方法已在实际中得到重视和应用。在中国被行业标准推荐和普遍应用的甲型和乙型水驱曲线，尚没有预测水驱体积波及系数的方法。在有关文献研究的基础上，提出了甲型和乙型水驱曲线预测水驱体积波及系数的方法。通过实例应用表明，甲型、乙型、丙型和丁型水驱曲线预测水驱波及体积系数具有很好的一致性。由于胡罡的“新方法”在推导中存在失误，导致所提供的方法是错误的，因此，有必要予以指正。

Abstract: The definition of water drive volume sweep factor is the ratio of natural water drive or artificial waterflooding occupied volume and oil pore volume. Water drive volume sweep factor is the important base for judging waterflooding development effect and EOR. The method for forecasting water drive volume sweep factor methods by Type?C and Type?D water drive curves has received attention and application in practice, while there still no related method by Type?A and Type?B water drive curves recommended by the petroleum industry standard and applied universally in China. This paper proposes the forecasting water drive volume sweep factor methods through Type?A and Type?B water drive curves based on the study of related literatures. The applied examples show that the water drive volume sweep factors predicted by Type?A, Type?B, Type?C and Type?D water drive curves have the very good consistency. The derivation from the "new method" given by Hu Gang is wrong, so, it is necessary to be corrected
