渗透速度
The wave velocity, permeability and porosity of rocks changed obvious around the threshold temperature.
在阈值温度附近岩石波速、渗透率和孔隙度变化幅度最大;
Based on the literature researches, considered the complex permeability characteristics of low permeability gas reservoirs, a three-dimension gas-water two-phase percolation mathematical model is established, which reflects the concrete influence factors, such as low velocity non-Darcy flow, starting pressure gradient and slippage effect.
本文基于国内外文献调研成果,针对低渗透气藏的复杂渗流特征,建立了低渗透气藏低速非达西流动三维、气-水两相渗流数学模型,该模型考虑启动压力梯度和滑脱效应的影响。
