摘　　要：为深化江陵凹陷精细勘探,进一步明确不同沉积时期的勘探领域,以油组为单元,开展新下段微古地貌特征研究。通过对不同油组地层的岩性、厚度及微古地貌的变化,更精细地展示不同油组沉积时期的微古地貌变化特征,为江陵凹陷进入精细勘探优选有利区奠定基础。To enhance the refined exploration of the Jiangling Depression and delineate the exploration targets in different sedimentary periods,this study investigates the micropaleogeomorphic characteristics of the new lower member at the scale of oil groups.By analyzing the variations in lithology,thickness,and micropaleogeomorphology among different oil groups,the study provides a more refined depiction of the micropaleogeomorphic features during the deposition period.These findings establish a solid foundation for identifying favorable areas for fine exploration and optimization within the Jiangling Depression.
