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.
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 the study of the cement flow rule in the crack, we analyzed the influence to diffusion radius by the grouting pressure, cement rheological parameter and grouting time.
通过研究水泥浆液在裂隙中的流动规律，分析了灌浆压力、浆液的流变参数和灌浆时间对扩散半径的影响。
