摘要
依据聚合物驱的驱油机理 ,在研究分析聚合物驱开发指标变化与水驱开发指标变化的共同之处和不同特点的基础上 ,借鉴水驱开发指标预测的驱替特征曲线方法 ,提出了可利用驱替特征曲线的方法预测聚合物驱开发指标。实际应用证明该方法预测精度较高 ,但它只适用于已有一定动态开发数据 ,一般在含水开始回升以后的聚合物驱区块的开发指标预测。根据聚合物驱开采注入量和采液量都保持相对稳定的特点 ,研究了聚合物驱开发指标预测的累积液累积水法。该方法不仅可以解决聚合物驱区块前期指标预测问题 。
Basing on the mechanism of polymer flooding, this paper proposes a method of usable flooding characteristic curve to predict the indexes of polymer flooding development. Application proves that this method has high prediction accuracy, but it is only suitable for the prediction on the polymer flooding blocks which have certain dynamic development data and water cut backstepping. According to the characteristic of relatively stable injection rate and produced fluid of polymer flooding, this paper studies accumulated fluid and accumulated water method for the prediction of polymer flooding.
