广义S增长曲线在油田开发中的应用

Application of generalized increasing model in oilfield development

通过对目前普遍采用的6种S增长曲线指标量增长率变化特征的分析,得到能够代表这6种增长曲线的广义S增长模型及增长曲线,建立了油田年产量、累计产量预测模型,并通过非线性回归方法对模型进行了求解。实例分析表明,所推导出的年产量、累计产量模型对实际油田预测结果较为准确。

Through analysis of the characteristics of index increasing rate of 6 S-shape increasing curves,which are commonly used currently,a generalized S-shape increasing model and its increasing curve are obtained,a prediction model of annual production and cumulative production is established,and the model is solved by non-linear regression.Case study shows that the model can give accurate prediction of annual oil production and cumulative production.
