Water lock effect 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.
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。
Water lock effect will bring harm to low permeability reservoir and impair reservoir productivity.
水锁效应对低渗透储层会产生伤害，严重影响气藏的产能。
With continues gas field development, formation pressure drops gradually, fluid intrusion and water lock effect are particularly prominent in gas well shutdown process.
随着气田的开发和天然气的不断采出，地层压力逐渐降低，生产气井在关井过程中的积液倒灌和水锁效应问题显得尤为突出。
