uniformity coefficient

A parameter for quantitatively describing the lateral heterogeneity of reservoir permeability —— heterogeneity factor is defined based on the percolation flow through porous media.

基于多孔介质中的渗流过程,定义了一个定量评价油藏渗透率水平非均质性的新参数———非均质系数。

Overall mass transfer coefficient and time averaged mass transfer coefficient of adsorption of SO_2 on activated industrial semi-cokes;

活化工业半焦吸附SO_2的总传质系数和时均传质系数

The features of pore space,throat radius,microcosmic uniformity coefficient and relative sorting coefficient of micro-fractured ultra-low permeability reservoir were compared with those of non-fractured ultra-low permeability reservoir under the condition of same permeability.

将不同渗透率的含微裂缝与相同渗透率、不含微裂缝低渗透砂岩岩心进行了对比,研究了微裂缝性特低渗透油藏的孔隙空间形态、喉道半径、微观均质系数和相对分选系数等特征,分析了这些特征对孔隙度渗透率性质、可动流体体积和压力敏感性等方面的影响。
