High velocity gas flow causes turbulence coefficient, while the existence of turbulence effect affects percolation flow characteristics of a reservoir.

由于气体的高速流动，产生了湍流效应，而湍流效应的存在，又影响了储层的渗流特性。

Generally, flow at high velocity around well bore in gas well is belong to non-Darcian flow which arising adding pressure drop.

通常情况下，气井井轴周围的高速流动为非达西流动，产生附加压降。

This paper presents a new gas well testing analysis method considering gas well producing at constant pressure in infinite gas reservoir accounting for high velocity non-Darcy flow ef.

对于定压生产气井试井分析，由无因次产量的倒数和无因次时间构成的常规半对数图在考虑高速流动效应时需要进行修正。
