capillary sealing and,capillary+pressure sealing.
在研究泥岩盖层封气性的形成条件及演化特征的基础上 ,对 3种类型泥岩盖层的封气性演化阶段进行了划分 :既无生气能力又无异常孔隙流体压力的泥岩盖层 ,其演化不存在阶段性 ,仅有毛细管封闭 ;具生烃能力但不具异常孔隙流体压力的泥岩盖层 ,其演化可分为毛细管封闭和毛细管 +压力封闭两个阶段 ;既具生烃能力又具异常孔隙流体压力的泥岩盖层 ,其演化可分为毛细管封闭、压力封闭 +毛细管封闭 +抑制封闭和毛细管封闭 +替代封闭 3个阶段。

Uncompacted mudstone has the capability of pressure sealing, which can not seal only oil and gas in free phase, but also oil and gas in waterdissolving phase.
欠压实泥岩具有压力封闭油气的能力,既可以封闭呈游离相运移的油气,又可以封闭呈水溶相运移的油气。
6) tamp and seal
