摘要
Arps递减曲线当递减指数n<0或n≥1时,不能计算可采储量,因而进行较长时间的预测结果不可靠。为此,人们先后提出的N1、N2、N3、Y1递减曲线已经很好解决了Arps递减指数n<0时的指标预测方法问题,提出的Y2递减曲线,不论n<0或0≤n<1或n≥1,即n为任意值的情况下,都能描述不同的递减规律,并计算出可采储量,其功能已超过了Arps递减曲线,具有推广价值。

Yu Qitai Professor of Engineering Reservoir Engineering Research Institute of Petroleum Exploration and Development CNPC Beijing 100083 China Abstract When Arps decline index n<0 or n≥1 the maximum recoverable reserves can not be estimated with Arps decline curves which tends to give unreliable results for long time reserves predictions. Hence available decline curves like N1 N2 N3 Y1 proposed later by other scholars have been well applied to solve the index predicting problem at n<0 where using Y2 decline curve in the case of arbitrary values of n the different declining rules and the recoverable reserves can all be described and estimated. The function of Y2 have been verified to exceed that of Arps decline curve so it is worthy of being popularized.
