| 摘 要： | 莱州湾凹陷东北次洼是渤海海域重要的油气富集区,通过对大量岩石薄片、扫描电镜以及储层物性数据进行分析,对垦利6-A构造深层砂岩储层的成岩作用和孔隙演化进行了详细研究。结果表明,该区深部储层在埋藏过程中经历了压实、胶结、溶解等多种成岩作用,根据镜质体反射率、粘土矿物演化分析等将该区成岩阶段划分为早成岩A期,早成岩B期,中成岩A期,中成岩B期四个阶段,并对各期孔隙演化特征进行了分析。

Diagenesis study on deep reservoir of Kenley 6-A structure in Laizhou bay sag |

| Abstract: | Sub-sag in the northeast of Laizhou bay sag is an important hydrocarbon enriched region in Bohai sea area.Through comprehensive analysis of rock thin section,scanning electron microscopy(SEM),and reservoir physical property,a detailed study of deep sandstone reservoir diagenesis and pore evolution of Kenley 6- A structure has been carried out.The results show the deep reservoir experienced compaction,cementation,dissolution and etc.during burial process.According to the vitrinite reflectance and clay mineral evolution analysis,the diagenetic stage can be divided into four phases,namely early A phase,early B phase,middle A phase and middle B phase.Besides that,the pore evolution characteristics of each phase have been analyzed. |
