摘要
在气井试井过程中，测试往往达不到拟稳态，这时使用产能方程存在一定误差。在产能方程的二项式表述时，二项式系数（Ａ、Ｂ）随探测半径增大呈一定规律性变化，同时，无阻流量亦发生规律性变化。在分析了上述有关的变化规律后。
Pseudosteady state seldom occurrs in gas well testing. In this case the use of
deliverability equation may obtain erroneous result. In binomial expression of deliverability
equation, the binomial coefficient (A,B) changes with the increase in investigation radius, and open
flow capacity also varies regularly. This finding can more effectively direct well test design and its
implementation.
