摘　　要：成岩作用是沉积岩石学、石油地质学、层控矿床学的重要研究内容。利用铸体薄片、扫描电镜、X–射线衍射分析、阴极发光等分析测试手段,对苏北盆地白驹凹陷洋心次凹泰一段(E1t1)储层成岩产物进行了详细研究。在综合分析各种成岩作用类型的基础上,进行了成岩阶段划分和各种成岩作用对储层物性影响的分析,认为泰一段基本上没有进入中成岩B期及晚成岩阶段;溶蚀作用形成的次生孔隙是泰一段储层的主要孔隙,其发育带往往是有利储层发育区,为认识研究区储集空间提供了有力的地质依据。The diagenetic results of reservoir bed of the 1st member of Taizhou Formation(E1t1)in the Yangxinsub-depression located in Baiju Sag in North Jiangsu Basin are studied in detail by means of the identification of thecasting sides under microscopes combined with scanning electron microscopy(SEM),X-ray diffraction analysis,cathodoluminescence,and other analytical tools. Based on the analyz set of the different diagenesis types,thediagenetic stages are classified and the impacts of the diagenesis on the reservoir properties are analyzed. Theconclusions are reached that E1t1 dose not basically come into middle diagenetic stage B or late diagenesis stage,and that the secondary porosity of E1t1 is the main rock pore under dissolutions and it is also the favorable reservoirspace,which provides a solid foundation for understanding the accumulative spaces of the Formation.
