| 摘 要： | 鄂尔多斯盆地大牛地气田二叠系下石盒子组储层砂岩具有成分成熟度低,结构成熟度中等到好的特点,岩性以岩屑石英砂岩和岩屑砂岩为主.砂岩属于特低孔特低渗储层,以次生溶蚀粒间孔为主要储集空间.储层成岩作用主要包括压实、溶解、胶结和交代4种,目前处于中成岩阶段B期.成岩作用对储集物性的影响主要表现在孔隙度和渗透率两方面.机械压实作...

| Abstract: | Reservoir sandstones of the Permian lower Shihezi formation in Daniudi gas field of Ordos basin,mainly consist of lithic quartz sandstone and litharenite,with low compositional maturity and median-high textural maturity.It belongs to extra-low porosity and permeability reservoir,with dissolved intergranular pores as the chief accumulation space.The lower Shihezi formation reservoir sandstones are now in the B stage of mesodiagenesis,the main diagenesis of which includes compaction,cementation,dissolution an... |
