摘要： 水驱特征曲线在水驱油藏动态开发中应用广泛，而常用水驱特征曲线大多数都是单一的曲线，且在选取直线段时受人为因素影响容易产生误差。在两种传统水驱曲线的基础上，提出一种新型水驱特征曲线，并应用回归软件对油田实际开发动态数据进行非线性拟合，以确定油藏累计产油量与含水率、油藏含水率与可采储量采出程度关系。通过实例检验了新型水驱特征曲线预测含水率上升规律的可行性、合理性。新型水驱特征曲线不仅适用于普通油藏开发后期高含水阶段，也适用于低渗透油藏中高含水阶段。

Abstract: The water drive characteristic curves is widely used in water drive reservoir development, while most of the traditional water rive characteristic curves are single curve. In this paper, a new type of water drive characteristic curve is established based on two traditional water drive characteristic curves, and the dynamic data of Xinjiang oilfield development are fitted by nonlinearity using regression oftware, and the relationship graphics of cumulative production vs. water cut and water cut vs. recovery percent of recoverable reserves are lotted. The case study indicates that this new type of water drive characteristic curve is practicable and reasonable in prediction of water ut rising pattern, and it can not only be applied to common reservoirs at high water cut stage, but also applied to low permeability reseroirs at mid?high water cut stage
