| 摘 要： | 根据砂岩薄片、铸体薄片、扫描电镜、X-衍射的分析,研究了苏里格地区盒8储层砂体的岩石学特征、成岩作用.储层砂体成分以岩屑石英砂岩为主,砂岩粒度较粗,分选磨圆中等一好.储层成岩特征表明:研究区砂岩的成岩处于中成岩B期,早期的压实作用、多种矿物胶结作用是使物性变差的主要原因.酸性及碱性介质条件下的溶蚀作用形成的次生孔隙对于砂岩的储集性能具有明显的改善作用.

| Abstract: | Based on the analysis of easting lamella,scan electron microscope and X-ray diffractions,this paper studied the characteristics of petrology and diagenesis on reservoir in the Member 8 formation in the Sulige area of Ordos Basin.The result show that the main sandstone in the area is rock debris quartz sandstone.The diagenetic characteristics of sandstone in the Member 8 formation show that this set of sandstones are in the B phases during media diagenesis.The early diagenetic compaction and multi-mineral ce... |
