水锁效应对低渗透储层会产生伤害，严重影响气藏的产能。
Water lock effect will bring harm to low permeability reservoir and impair reservoir productivity.
因此，当边水和底水进入储层发生水淹后，气相渗透率将极大降低，存在较强的水锁效应。
So, after reservoir watering out as edge water and bottom water enters, the gas phase permeability will decrease greatly, and strong water lock effect will happen.
结果表明影响低渗气藏的主要因素有应力作用、启动压力梯度、渗透率、滑脱效应、水锁效应等。
It is indicated that the main factors affecting low permeability gas reservoir are stress action, start-up pressure gradient, permeability, slippage effect, and water blocking effect etc.
