摘要
产量递减规律的研究对搞好气藏开发后期调整、产量预测及可采储量复核都有重要意义,目前现场上主要运用Arps递减曲线来研究气藏的递减规律。此外,国内外很多学者还提出了其它的预测方法,都不同程度地完善了Arps递减曲线法使得应用范围更广泛,预测精度更高。文章结合Arps指数递减和翁氏模型导出了一个复合递减模型,并在实际应用中得到了很好的验证。
To study the production decline is very significant for the later adjustment, production prediction and recoverable-reserves rechecking during a gas reservoir development. So far, the Arps decline-curve method is a key one, which is adopted to study the decline law and may obtain a higher accuracy during a prediction. In addition, other prediction ways are presented by some researchers at home and abroad. They also improve and perfect this Arps decline-curve method. Integrated Arps exponential decline and Weng's model, a compound production decline model is deduced and has obtained a better result in actual application.
