vertical permeability

a new method for vertical permeability estimation

一种确定地层垂向渗透率的新方法

in anisotropic formations, the smaller the vertical permeability, the greater the impact of formation damage on productivity.

各向异性地层中，垂向渗透率越小，地层伤害对产能的影响越大；

effect of vertical permeability of interbed on the oil saturation of the reservoir with low permeability

夹层垂向渗透率对低渗透油层含油饱和度的影响

heterogeneity is strong, vertical permeability showed positive rhythm and rhythm is a combination of complex features.

储层非均质性较强，纵向上渗透率的变化表现出正韵律和复合正韵律的组合特征。

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。

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 test and analysis of vertical permeability of formation

地下岩体的垂向渗透率测试及分析

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.
