【摘要】 致密低渗透砂岩储层一般以高含水为特征，其中缚水以水膜和毛管水形式存在。本文针对这些特点，从水膜形成、存在的物理化学机理出发，着重讨论水膜的性质及其对流体渗流的影响，并考虑以减小水膜厚度和改变水膜性质为思想基础进行致密低渗透砂岩储层改造。更多还原

【Abstract】 The tight and low permeability sandstone reservoir generally shows character of highly filled water,and its irreducible water exists in water film and capillary water types in light of these.In this paper proceeding from the physicochemical mechanism of water film formation and existence.It is discussed about the property of water film and the effecting to the fluid of it,and consider to reform the tight and low permeability sandstone reservoir on the basis of decreasing water film thickness and changing property of water film.更多还原
