vertical permeability

The influences of spinning speed, bonding area and roller pressure on the permeability performance of PET spun-bonded prefabricated vertical drain filters were tested and analyzed.

测试和分析了纺丝速度、轧点面积和轧辊压力对纺粘热轧滤膜透水率的影响。

The sample of the test instrument is designed as a rectangular parallelepiped. To facilitate preparating samples of permeability characteristics in both horizontal and vertical directions, front and rear covers and superstructure is designed to be freely opened and closed.

试验仪器的试样形态为长方体，仪器的前、后盖及上盖可以自如开启及闭合，便于制备研究水平、垂直两个方向渗透特性的试样。

These felts, manufactured mainly from wool, had low vertical permeability and poor service life.

这些毛毯生产主要来自羊毛, 具有低的垂直渗透率和差的使用寿命.

In vertical, as for interlayer scale, oil saturation had no positive correlations with the porosity and permeability, while had some relations with the burial depth under the effect of petroleum accumulation environment.

垂向上，对于层间规模，代表储层内部油气分布的含油饱和度与储集物性不存在正相关关系，而是受成藏背景影响与深度存在一定对应关系。
