摘要(Abstract)：
该文对Казаков水驱特征曲线表达式进行了推导和研究，实际应用表明，Казаков曲线可以进行油田产量、累积产量、含水率等开发指标的预测及可采储量的计算。利用Казаков曲线进行逐年可采储量的计算表明，与实际值的相对误差仅为２．４９％。
The paper deduces and studies the expression form of the Казаков water displacement characteristic curve. The actural application shows that this curve can not only predict development indexes,such as oil production rate,cumulative production,water cut and so on, but also calculates recoverable reserves.The result of the above calculation year after year shows that the relative error is only 2.49% compared with the actual value.
