【摘要】：产量递减曲线分析在预测产量和提高储层采收率方面具有重要作用,其目的是确立产量与时间之间的关系,从而预测产能走势。Arps方程法和Arps方程改良后的产量曲线分析法目前在常规储层方面得到了广泛应用,但这些传统的方法并不适用于页岩储层之类的非常规储层。着重介绍了双曲线方法、Gentry方法、经验延伸法和Duong方法等非常规油气层产量曲线的分析方法。基于对几种产量曲线分析法进行概述的同时,借助Duong方法易比较和产量曲线易拟合的优势,论证了该方法对页岩储层生产预测的适用性;通过对瞬变流体和边界控制流体2种流态下产量曲线的分析计算,建立了经验方程式。最后,利用实际数据验证了Duong产量曲线分析方法的可行性。
[Abstract]:The analysis of production decline curve plays an important role in predicting production and improving reservoir recovery. Its purpose is to establish the relationship between production and time. Thus, the method of predicting productivity trend. Arps equation method and the improved production curve analysis method of Arps equation have been widely used in conventional reservoirs. However, these traditional methods are not suitable for unconventional reservoirs such as shale reservoirs. The hyperbolic method and Gentry method are emphatically introduced. The empirical extension method and Duong method are used to analyze the unconventional oil and gas reservoir production curves, which are based on the summarization of several kinds of production curve analysis methods at the same time. The applicability of the Duong method to shale reservoir production prediction is demonstrated by virtue of the advantages of Duong method which is easy to compare and the yield curve is easy to fit. By analyzing and calculating the yield curves of transient fluid and boundary controlled fluid, the empirical equation is established. Finally, the feasibility of Duong yield curve analysis method is verified by the actual data.
