摘要
用物质平衡法和Logistic模型联解,可以建立水驱油藏或区块平均含水饱和度随时间变化的预测模型。该模型仅需要少量的开发数据,求解过程极其简单。通过实例分析,说明该方法简单、实用,不失为一种有效的预测法。该方法适用于进入开发中后期、产量处于递减阶段的油藏或区块的平均饱和度预测。
The model of average water saturation changes with time in waterflood reservoir or block is developed by using material balance method combined with Logistic model, by which few production data are required and the procedure for solution is very simplified. The case study shows that this method is practical as an effective way for prediction of average fluid saturation of reservoir or block in the period of production decline for mid-tail development phase.
