matrix of coal的意思|示意

The matrix pores in coal play a little role in fluid flow, therefore the permeability derived from well test is the reflection of the percolation flow capacity in cleat system.

煤基质的孔隙性对流体流动影响极小，试井所得渗透率反映的是割理系统的渗流能力。

The obvious slippage effect for gas flow has been found due to the low gas permeability, and the effect of coal matrix shrinkage on the permeability is also indispensable.

低渗透气藏中的气体渗流具有明显的滑脱效应，同时煤基质收缩效应对煤层渗透率的影响也是不容忽视的。

The diffusion of coalbed methane in coal reservoirs is defined that the main process of coalbed methane desorbed from coal matrix pore surface migrated to cleat system.

煤层气在煤储层中的扩散是指从煤基质孔隙表面上解吸的煤层气运移到割理系统的主要过程。
