摘要
低渗气藏具有强非均质性、低孔、低渗等特点。本文主要针对低渗气藏渗流影响因素进行了分析,分析表明气体在低渗气藏中的渗流受滑脱效应、启动压力梯度、应力敏感、水锁效应及含水饱和度等因素的共同影响。
The geological condition of low permeability gas reservoir features strong heterogeneity, low porosity and permeability.This article describes the factors that contribute to the gas flow in low permeability gas reservoirs, which include the slippage effect,starting pressure gradient, stress sensitivity, the water lock effect and water saturation.
