At the end of this paper, model sketches, pressuredrawdown solutions, theoretical curves and practical example analysis are presented for comparing.
文中附有模型简图对比，压降解对比，理论曲线对比，及实例分析对比。

Then a differential model, which discribes the changes of sandface flow rate under pressuredrawdown and buildup is derived. The rate model is used to solve the question …
The existent pressuredrawdown analysis technologies were only suitable for low permeability and isotropy reservoirs, not for interpreting fracture parameters of fractured reservoirs.
