1) Self-locking effect
自锁效应
2) water block
水锁效应
1.
During the exploitation of gas condensate reservoir, especially the low permeability reservoir, the condensate oil will come out when the pressure drops down to the dew-point pressure, which will cause condensate block and decreases the well productivity, the situation will be worse if the water block exist.
针对凝析气藏特别是低渗透凝析气藏在开发过程中,地层压力降低到露点压力以后,凝析油会析出到地层中,造成反凝析污染,使气井产能下降;有时有水锁效应,产能将进一步降低,从而对凝析油、气采收率等产生严重影响的问题,在调研了国内外文献的基础上,探索了注甲醇段塞+N2(干气)吞吐解除反凝析、反渗吸污染,恢复气井产能方法,并设计了甲醇-地层水-凝析油气三相体系PVT相态测试方法和注甲醇段塞+N2(干气)吞吐解除反凝析、反渗吸实验测试及评价方法,该方法在现场得到了成功应用。

4) Water blocking effect
水锁效应
1.
The permeability loss of the core induced by clay swelling or water blocking effect can be determined respectively from the augmentations of volume of bound water as a result of invasion of the fracturing fluid and the oil phase retentions after the flowback.
通过测量压裂液侵入岩心引起的束缚水增加量、油相反排后的滞留量,能够分别判断出粘土吸水膨胀、水锁效应引起的岩心渗透率伤害程度,由此获得了压裂液对致密岩心伤害程度和机理的新认识。
2.
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.
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。
5) water locking effect
水锁效应
1.
In addition,the narrow flow channels for gas and water,the strong filtrational resistance and the larger superficial tension of both liquid-solid and liquid-gas interfaces may result in an obvious increase of water locking effect and stress sensitivity.
气、水赖以流动的通道很窄,渗流阻力很大,液、固界面及液、气界面的表面张力较大,使水锁效应和应力敏感性明显增强。
2.
So, the water locking effect forms.
低渗气藏砂岩孔喉半径小、毛细管压力大,施工过程中工作液容易吸入储集层,近井地层含水饱和度明显升高,天然气的流动能力明显降低,形成水锁效应。
6) Water-locking effect
水锁效应
1.
Its formation mechanism includes well-developed net-shaped clay in tight sandstone which fill the intergranular pores and form micropores, and water-locking effect which can enhance capillary pressure and reduce greatly the gas permeability as well so as to make it the effective caprock of gas reservoir.
英南2气藏之上非常规致密砂岩作为盖层,形成机理是致密砂岩中网状粘土发育,充填于粒间,形成大量微孔隙,水锁效应增大毛细管压力,极大地降低气体渗透率使其成为气藏有效盖层。
补充资料：用户锁定效应
信息产业中的产品还具有很强的用户锁定效应，这是信息产品区别于传统的工业制成品的又一项显著特性。多数信息产品都处于某个系统中，单件产品只有与其他产品相互配合才能发挥作用。因此用户在购买了某件产品之后，通常还要购买配套的硬件和软件，并且学习产品的使用方法，才能充分发挥其效用。此时，一旦用户向某种特定的系统中投入各种补充和耐用的资产时，就会产生锁定。这种情况在信息产业中是非常普遍的现象。锁定程度的大小与早期的投入，即转移成本有关。投入越多，则锁定程度越高。
