摘要
基于西帕切夫水驱曲线和HCZ累积产量预测模型，建立了水驱油田含水率随油田开发时间变化的关系式，该方法克服了甲、乙型水驱曲线的不足，适用于含水率低于50％的情况下水驱油田含水率的预测，矿场实例运用结果表明：该方法计算简单、方便，预测的含水率精度较高，比较符合油田的开发实际，可作为水驱油田制定中，长期开发规划的依据。
Based on the N. V. Sipachef curve of water displacement and HCZ prediction model of cumulative oil production, this paper has presented an equation which relates water cut with production time in a oilfield. Without shortcomings as in water displacement curves of Type A and B, this method can be used to predict water cut in oilfields with water cut less than 50%. Field applications indicate that this method is simple and convenient in calculation and accurate in water cut prediction, and accord well with the demands of actural production in oilfields. So the method is helpful to making medium long development plans for water drive oilfield.
