递减曲线和增长曲线结合预测油田调整效果——以飞雁滩油田三采区为例

预测油田调整后的产量变化，是评价调整效果的重要手段之一。为了快速、准确地预测油田调整后的产量，文章结合递减曲线和增长曲线的优点，利用Arps双曲递减曲线预测油田调整前正在递减的产量，利用Weibull增长曲线预测油田调整后产量的变化，对飞雁滩油田三采效果进行了预测，并与其他预测结果对比分析，认为该方法预测结果可信度较高，且具有简单易行、人为因素影响小的特点。

Application of integrated decline and increase curves in forecasting oilfield adjustment effect:a case study of tertiary oil recovery region of Feiyantan Oilfield

Forecasting production is one of the major approaches while estimating the effectiveness when oilfield development is to be adjusted.This paper combines the advantages of both the decline curve and the growth curve In order to predict the production quickly and accurately.The Arps hyperbolic decline curve is used to predict the production declining.The Weibull growth curve is used to predict the production after the oilfield development is adjusted.Using this method,the effect of tertiary process is estimated and the results are compared to those from other methods.It indicates that the method is easy and simple and has little man-induced effect.
