地层原始渗透率越低，地层渗透率降低程度越大；

The higher the salinity and lower the initial formation permeability, the greater the permeability reduction.

对于一口新井，确定原始地层压力、有效渗透率、总表皮系数、附加压力损失和流动效率，是试井的重要任务。

For a new well, it is an important work to determine initial reservoir pressure, effective permeability, summary skin coefficient, supplementary pressure loss and flow efficiency.
