| 摘 要： | 通过岩石薄片、铸体薄片、扫描电镜、常规压汞、恒速压汞、核磁共振等分析化验资料,从微观和定量的角度研究低渗透储层的孔隙结构,分析填隙物对低渗油藏孔隙结构的影响.孔隙结构是决定储层物性的内在因素,低渗透储层由于喉道细小,孔隙结构复杂,导致物性较差.而填隙物的类型及含量是孔隙结构最主要的影响因素之一.

| Abstract: | The pore structure of low permeability reservoirs and the effects of interstitial material on the structure were analyzed macroscopically and quantitatively in the paper based on the analysis and test data from rock thin section,cast thin section,scanning electron microscope,conventional mercury penetration,constant rate mercury penetration and nuclear magnetic resonance,etc.Pore structure is the inherent factor determining the physical properties of reservoirs.Low permeability reservoirs have poor physical... |
