permeability to gas flow的意思|示意

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。

Methods of experiment, theory and calculation were used to establish a new nonlinear flow law. Experiment results of gas flow in low permeability pore-fissure media were analyzed.

采用实验、理论与计算相结合的方法建立低渗透孔隙-裂隙介质气体非线性渗流运动方程。

This paper presents a new method of steady flow to solve the problem that the injection rate into cores is difficult to get steady, especially for gas in measuring relative permeability.

本文就用稳定法测量相对渗透率曲线中，存在的注入流量难以稳定的问题，提出了一种新的稳流方法。

For the low porosity and permeability reservoir of Shi Wu Oilfield, fracture is the main flow channel of oil and gas. So it is essential to do a comprehensive research on the fracture.

对于十屋油田营城组低孔低渗储层，裂缝是油气的主要渗流通道，所以有必要对裂缝进行全面的研究。
