摘要： 从油水相对渗透率比与含水饱和度的关系出发，对丁型水驱特征曲线（纳扎洛夫水驱特征曲线）进行了推导，从理论上证明了丁型水驱特征曲线直线段斜率的倒数同地质储量呈线性关系。通过对塔河油田12个单元区块的统计，验证了这一结论，同时确定了缝洞型油藏的线性比例系数为6.4，建立了利用丁型水驱特征曲线计算地质储量的方法。利用这一方法，对塔河油田T7-607单元和T7-615单元的单井井控储量进行计算，计算结果同地质认识具有较好的一致性。说明利用该方法计算塔河油田碳酸盐岩缝洞型油藏单井井控储量是可行的。

Abstract: Nazalov water flooding characteristic curve (Type-D curve for short) was derived from the relationship between oil-water relative permeability ratio and water saturation. It was proved that there was a good linear relation between the reciprocal of the slope of the linear part in Type-D curve and the original oil in-place (OOIP). This conclusion was verified through the statistics of 12 units in Tahe oilfield, and the proportional coefficient of 6.4 was determined for the fractured-vuggy reservoir. Using this method, the single well controlled reserve was calculated for wells of T7-607 unit and T7-615 unit in Tahe oilfield. The results are consistent with the geological knowledge, which shows that the method proposed in this paper is feasible for calculation of such a carbonate reservoir’s well controlled reserves in Tahe oilfield
