摘　　要：利用钻测井资料以及大量实验分析数据,针对阜东斜坡带齐古组高分辨层序地层格架内储集砂体的成岩特征及演化进行详细研究。结果表明:研究区高分辨层序界面控制了胶结物的溶蚀作用、颗粒之间的接触关系、绿泥石含量。中期旋回共有2种结构类型,研究中针对不同结构类型的中期沉积旋回内成岩特征进行了探讨,反映出层序地层学与成岩作用存在着一定的关系。可见,针对不同结构类型的重点旋回进行成岩演化特征分析,为面积较小区域内优质储层的寻找提供指导。On the basis of previous research of sequence stratigraphy,characters and evolution of diagenesis in high resolution sequence stratigraphical framework of reservoir sand in Qigu formation in Fudong slope area were analyzed by making use of drilling and logging data as well as lots of experimental analysis data.The results indicate that sequence interface is able to control dissolution of cements,contact relationship between grains,content of chlorite.There are two structural types of mid-term cycle,and diagenesis character within different structural types of short-term cycles are discussed,which reflects sequence stratigraphy has a certain relationship with diagenesis.The analysis on diagenesis evolution in important cycles with different structural types is able to provide guidance for finding great reservoirs in small area region.
