| 摘 要： | 砂岩储层的微观非均质性主要由砂岩孔隙特征、粘土矿物和孔喉分布等表征。通过岩心样品的常规薄片,铸体薄片、扫描电镜观察和粘土矿物X—衍射分析以及孔隙结构图象分析,揭示了大港枣园油田孔一段砂岩微观非均质性为中到强非均质储层,孔二段砂岩为强非均质储层,并建立了各层段的非均质模式,提供了相应的增产改造措施,使开发效果得到改善。

| Abstract: | The microheterogeneity in the sand reservoirs is represented by the pore nat-ure, clay mineral composition and pore throat distribution. Through the conven-tional thin section, injecting thin section and SEM observations and X-rayanalysis of clay minerals and pattern analysis of pore structure, it has been re-vealed that the sandstone of the First Member af the Kongdian Formation of theZaoyuan Oilfield, Dagang, is intermediatcly to strongly heterogeneous reservoir rock, while tho Second Member sandstone of the Kongdian Formation is stronglyheterogeneous reservoir rock. Microheterogeneity models for various horizons andthe related measures for enhancement of oil revocory are presented in the paper,which can improve the results of development. |
