摘要
论文通过对济阳坳陷东营凹陷碳酸盐岩储层成岩作用分析,在碳酸盐储集岩中识别出了9种成岩作用,进行了成岩阶段的划分,结合成岩作用、孔隙演化和孔隙充填,建立了不同成岩期的成岩作用类型、孔隙演变及其它们间的相互关系,提出了6种成岩相。研究认为不同的成岩相对储层建设性起着不同的作用,白云岩化作用、溶蚀作用、去白云石化作用、构造破裂作用和流体充注作用对优质储层的形成与破坏起着非常重要的控制作用。研究成果对于陆相碳酸盐岩成岩作用的研究具有一定的参考价值。
Nine kinds of diagenesis were recognized on the basis of studying the carbonate reser- voir of Dongying Sag in Jiyang Depression. The diagenetic stages and diagenetic types of different diagenetic stages were established and classified. Also,pore evolution and their relation with dia- genesis, pore evolution and pore filling process were discussed. Accordingly, six kinds of diagenetic facies were proposed. It was showed that different diagenetic facies played different roles in reser- voir formation. Dolomitization, denudation, dedolomitization, tectonic disruption and fluid pack-in- jection played significant role in dominating the formation and disruption of high quality reser- voir. This research result provided valuable reference for the further study of continental carbon- ate diagenesis.
