摘要(Abstract):
中国许多油田已进入高含水期开发阶段,需要适用于高含水条件的经济可采储量计算方法。基于数理统计学模型,提出了用分流量预测模型来计算经济可采储量的新方法,通过油井井底的平均含水饱和度与含水率之间的关系曲线,评估其最终经济可采储量。油田的实际资料应用表明该预测方法适用于高含水期油田。
Many oilfields in China have entered into the stage of high water-cut development,so it is necessary to develop a calculating method to adapt the computation of the economic recoverable reserve at this stage.Based on the model of mathematical statistics,the new calculating method of the above reserve is established with the help of fractional flow predicting model.Through the relation between the average water saturation and water cuts in the bottom of oil producers,the ultimate recoverable reserve is evaluated.The practical oilfield application indicates that the forecasting method is suitable to the development of high water-cut oilfields.
