摘要
水驱曲线是计算水驱开发油田可采储量的重要方法.在应用中,极限含水率选值和各类型曲线适应性一直是人们关注并争论的重要问题.通过大量的实际应用发现,根据水油比和产量的半对数直线关系确定极限含水率,并根据含水率与累积产量关系拟合曲线,选择适当的水驱曲线类型,在生产动态研究及可采储量标定过程中,取得很好的实际应用效果.
The water-flooding curve is one of the important methods to calculate recoverable reserve. The value of limited water-cut and the adaptability of every style curves are two important problems which are discussed and be given more attention. By lager mumble, it is obvious that during the declining period： WOR is linear with the yield in semi logarithmic system. We can select the advisable water-flooding curve to demarcate recoverable reserve in base of the curve water-cut ＆ cumulating, it has special effect in the application.
