摘要： 通过理论分析证明：Y2 递减仅仅是 Arps 双曲递减的一个变形,并没有作任何理论上的改进;Y2 递减仍然不能计算当 Arps 递减指数 n≥1 和 n<0 时的可采储量;Arps 公式中的初始递减率 Di 和递减指数 n 与 Y2 公式中的参数a 和 b 的关系为：n=1/b,a=1/nDi. 采用这两种方法对俄罗斯的罗马什金油田的递减数据进行分析,证明了理论分析的正确性。

Abstract: It is theoretically proved by this paper that: (1)Y2 decline curve is only a transformation of Arps decline curve without any improvement in theory and form; (2)Y2 decline curve can still not be applied to calculate the recoverable reserves when decline index of Arps n≥1 and n<0; (3) relationships between the primary decline rate Di and decline index n of Arps formula and the parameters a and b of Y2 formula are as follows: n=1/b, a=1/nDi . The two methods are applied to Romashikino oilfield of Russia for its decline data analyses, and the results indicate the validity of theoretical analysis in this paper.

Key words: Y2 decline curve, Arps decline curve, analysis
