利用该模型可以对火烧油层注气井试井压降曲线进行解释，并求解流度比、扩散比以及各区的波及半径等参数。

With this model, the pressure drop curve of well testing is interpreted, and mobility ratio, diffusion ratio, sweep radius of each area and some other parameters are solved.

在此基础上提出了用不稳定试井资料确定气井产能的新方法，即用压力恢复曲线法与压降曲线法相结合确定气井产能的新方法。

Based on these, the new method that pressure build-up curve associated with pressure fall-off curve to determining the productivity of gas well is proposed.
