| 摘 要： | 长6油层组储集砂岩主要为岩屑长石砂岩,粒度较细,分选中等偏差,填隙物主要为碳酸盐矿物和粘土矿物。砂岩的物质组成影响着其储层性能,储层物性随着石英含量的增加而变好,而随着岩屑含量的增加而变差。砂岩中长石的溶蚀作用是改善储层物性的关键因素。填隙物的含量越大,则孔隙喉道堵塞和充填的程度增加,导致储层物性变差。

| Abstract: | The emphasis of this study is placed on the types and characteristics of the reservoir sandstones and their bearings on physical properties of the Chang-6 oil measures in the Yanchang Formation,Huaqing region,Ordos Basin.The reservoir sandstones are represented by lithic feldspathic sandstone with finer grain sizes and moderate to poor sorting.The interstitial materials contain carbonate minerals and clay minerals.The physical properties of the reservoir sandstones are progressively getting better in respon... |
