摘　　要：在对中国近海多个典型水驱油田含水上升规律进行分析的基础上,通过与常用水驱曲线方法预测精度的对比,论证了广适水驱曲线的适应性。结果表明,广适水驱曲线适用范围广、预测精度高、简单易用,可应用于油田或单井水驱规律及产量预测,也可推广应用于合理提液时机与幅度判断、产液结构优化调整、侧钻界限评价及平台设施改建评估等多个方面。On a basis of analyzing water cut increase in several typical water-drive oilfields offshore China, the applicability of an eurytopic water-drive curve was demonstrated, by comparing with other common curves in prediction accuracy. The results have shown that the eurytopic curve is wide in applicability, high in prediction accuracy, simple and easy to be used. Therefore. this curve not only can be used in predicting the water drive trend and production for an oilfield or a well, but also has several extensible applications, such as judging the reasonable time and range of liquid producing, optimizing the structure of liquid producing, evaluating the limit of sidetrack drilling and assessing the reconstruction of platform equipments.
