In limestone districts, ecological environment is more and more severe due to low water retention capacity, low productivity and growing rocky desertification.───石灰岩地区持水力差，生产力低下，石漠化严重，生态环境日趋恶劣。
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。
Low permeable reservoir is mainly featured by small reservoir pore, fine throat, high filtration resistance, low oil productivity and low water absorbing capacity.───低渗透油藏的主要特点是储层孔隙小、喉道细、渗流阻力大，油井产油能力和吸水能力都非常低。
