No scholar once though that high velocity non-Darcy flowis easer to occur in lowpermeability reservoir in previous research results. Forchheimer equation is still used to gas high velocity flowin gas reservoirs for long time, and the gas flowequation of non-Darcy flowwould be derived fromthe 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.
