本文提出了试井期间改变井筒储量的分析模型，模型以井筒相再分布后模型的变体及扩展为基础。其结果为拉氏空间基本解，它可以将改变着的井筒储量增加到油井地模型中。井筒储量增大或减小情形都可分析计算，并提出的各种现场实例说明改变井筒储量在试井中的应用。
This paper presents an analytical model for changing wellbore reserves during well testing. The model is based on variations and extensions of the model after wellbore phase redistribution. The result is a basic solution to the Laplace space that adds the changing wellbore reserves to the well model. The increase or decrease of wellbore reserves can be analyzed and calculated, and various field examples are presented to illustrate the application of changing wellbore reserves in well testing.
