First through a low velocitycore, and then through a high velocity shell, where their speed is increased before they are transmitted into the surrounding seawater.
Nitrogen gas with different displacing velocity and pressure was used to displace the core in testing, the permeability damage and correlation analysis caused by velocity sensitivity were obtained.
实验用氮气以不同的驱替速度和驱替压差驱替岩心,得到由速敏性引起的渗透率损害及相关分析结果。

The relationship between the lamellar spacing and the edgewise growth velocity under the specific undercooling is the core of growth kinetics.
