砂岩储集岩几乎都是孔隙性储集岩。七十年代以来,国内外对砂岩的孔隙几何学已有了不少专门的研究,人们逐渐认识到,尽管砂岩组份稳定,但在漫长的成岩过程中,由于物理化学条件的改变,岩石经历了一系列成岩变化,砂岩的孔隙类型和孔隙结构相应变得十分复杂。 Sandstone reservoir rocks are almost all porous reservoir rocks. Since the 1970s, there have been many studies on the pore geometry of sandstone at home and abroad. People gradually realized that although the sandstone component is stable, in the long process of diagenesis, due to the change of physical and chemical conditions, the rock experience After a series of diagenetic changes, the pore type and pore structure of sandstone have become quite complicated.
