摘　　要：低渗气藏在我国天然气资源中占有极大的比例,已成为天然气开发的主战区。然而由于低渗储层孔隙空间小,流体渗流阻力大,在开发过程中更易受到储层伤害,严重时甚至造成气藏无法产出,因此对低渗气藏的潜在伤害因素及伤害机理进行研究,并提出相应保护策略,有利于提高低渗储层开发效果。对低渗储层潜在伤害因素进行了系统分析,对指导低渗气藏高效开采具有重要意义。Low-permeability gas reservoirs occupies a large proportion of my country's natural gas resources and have become the main battlefield for natural gas development.However,due to the small pore space and high fluid seepage resistance of low-permeability reservoirs,it is more vulnerable to reservoir damage during the development process,and in severe cases,the gas reservoir may even fail to produce.Therefore,the potential damage factors and damage mechanisms of low-permeability gas reservoirs should be studied,and corresponding protection strategies need be proposed,which are conducive to improving the development effect of low-permeability reservoirs.In this paper,the potential damage factors of low-permeability reservoirs were systematically analyzed,which was of great significance for guiding the high-efficiency production of low-permeability gas reservoirs.
