没有任何一位学者的研究结果显示＂低渗透储层容易产生高速非达西流＂。Forchheimer公式一直被应用于高速气体渗流,该式经变形可得到气体渗流方程,导出的非达西渗流湍流系数理论方程与经验公式是一致的,进而认为Forchheimer公式中的非达西流湍流系数经验公式是正确的。有学者之所以否定Forchheimer公式中的非达西渗流湍流系数经验公式的正确性,其主要源于错误地描述了湍流阻力系数与雷诺数的函数关系。进一步研究给出了Forchheimer公式的线性化求解非达西渗流湍流系数的方法。

No scholar once though that high velocity non-Darcy flow is easer to occur in low permeability reservoir in previous research results. Forchheimer equation is still used to gas high velocity flow in gas reservoirs for long time, and the gas flow equation of non-Darcy flow would be derived from the equation. The author derived a theoretical equation of turbulence coefficient of non-Darcy flow, and the theoretical equation form accords with empirical equation when comparing the both equations. It is proved that empirical equation of turbulence coefficient of Forchheimer equation is right. Some people thought that empirical equation of turbulence coefficient of Forchheimer equation is not right, and it rooted in a wrong relationship between Reynolds number with resistance factor of turbulence flow, which was used. A linearization solution method of turbulence coefficient of Forchheimer equation is also expressed.
