摘要： 递减曲线在油气田中长期产量预测和可采储量标定工作中得到相当广泛的应用。在递减曲线分析中,一直存在两个未能解决的问题,即如何判断递减数据的有效性及结果的唯一性。应用 Arps 递减方程建立的 Q t 与 t 的关系曲线可以有效解决这两个问题。应用实例表明,该方法是可行的、有效的。

关键词: 递减曲线, 产量预测, 可采储量

Abstract: In the production decline curve analysis, there have been two unresolved problems, namely how to determine the effectiveness of such data and the uniqueness of the results. This paper presents the relation between Qt and t established with Arps hyperbolic decline equation, by which the problems can be solved. Case study shows that this method is feasible and effective.

Key words: decline curve, production forecast, recoverable reserve
