3.
A method of binomial deliverability equation can be used in abandonment pressure evaluation to reveal the original pressure, burial depth, heterogenity, and to show the effects of different abandoning conditions on abandonment pressure.
二项式产能方程法评价气藏废弃压力能够反映出气藏原始压力、气藏埋深、储层非均质特征、以及不同废弃条件等多种因素对于废弃压力的影响,因此该方法评价结果较传统废弃压力评价方法如经验法、气藏埋深法等更可靠。

二项Thue方程
1.
In this paper,using some properties of Pell equations and binomial Thue equations,we prove that the equation x+…xm=yn has only the positive integer solutions (m,n,x,y)=(1,r,sr,s),(r,1,s,s+…+sr and (sr,r,1,s),where r and s are arbitrary positive integers.
利用Pell方程和二项Thue方程的性质证明了:方程x+…+xm=yn仅有正整数解(m,n,x,y)=(1,r,sr,s),(r,1,s,s+…+sr)和(sr,r,1,s),其中r和s是任意正整数。
