用拟合曲线进行产量历史变化分析

Production Decline Analysis by Matched Curves

我国大多数油田已出现产量递减现象,产量递减分析在油田生产中的重要性日益明显,传统的产量递减模型在计算和预测方面比较繁琐。以生产历史数据数理统计为基础,确定出5种产量变化的历史拟合模型。现场应用表明,这几种模型能够很好地实现生产数据历史拟合,对产量预测精度的提高也有很大的帮助。

The produetion declines have appeared in most domestic oilfields,And the production decline analysis is more and more important for traditional models for it are more complicated in calculation and prediction.This paper presents five history-match models for production decline/variation by means of mathematic statistics of the production istory data,Case strdy indicates that these models are well used to run the history match and improve the accuracy of prodution prediction.
