near wellbore formation damage

基本解释

The method of using mixture of HF and HCL to treat sandstone formations of remove formation damage near the wellbore is a widely used stimulation treatment.
使用土酸处理砂岩地层，解除井壁附近地层伤害，是广泛采用的一种增产措施。
Hydraulic fracturing creates high-conductivity communication with a large area of formation and bypasses any damage that may exist in the near-wellbore area.
水力压裂提供了与地层的一个大的区域的高传导性连通，并对在近井地带可能存在的任何地层损害设置旁路。

Meanwhile, reverse imbibitions water blockage effect would be appeared to further damage the near the wellbore formation, especially in the low permeability and low productivity condensate gas wells.
同时，在近井带还会形成反渗吸水锁效应，从而进一步加剧近井带地层伤害，对低渗低产凝析气井，这一现象尤为严重。
