摘　　要：结合研究实例 ,提出了根据成因地层学分析的储层地层单元分级以及充分认识沉积微相基础上的小层划分与对比 ;同时 ,依据钻井、测井资料 ,以环境水动力条件变化为基础总结出稳定型、分叉型、尖灭型、稳定叠置型、叠置分叉型、叠置尖灭型等 6种小层稳定性类型。Division and correlation of substrata is important and basic in reservior description. Taking an actual instance as an example,this paper presents a way of dividing levels of layer units and a method of division and correlation of substrata based on the recognization of sedimentary microfacies. Meanwhile it suggests 6 types of correlation namely∶ steady, split, pinch, stack, stack pinch, and stack split on the basis of well core and logging and changes in water power of environment.
