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.

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.
