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。
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 D~ and decline index n of Arps formula and the parameters a and b of Y2 formula are as follows: n=1/b, a=1/n Di. 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.
