摘　　要：以高分辨率层序地层学与沉积学等理论方法为指导,综合利用岩心、录井和测井等资料,对沙埝油田沙7块阜三段进行了高分辨率层序地层划分与对比。根据基准面旋回和可容纳空间变化原理,识别出研究区短期和中期2个级次的基准面旋回层序,其中短期旋回层序以向上"变浅"的非对称型和对称型2种基本结构类型为主;在各级次基准面旋回层序识别的基础上,将阜三段划分为3个中期旋回层序和17个短期旋回层序,并应用旋回等时对比技术进行了精细地层对比,建立了沙7块阜三段高分辨率层序地层对比格架,为进一步的储层物性预测及储层结构描述等精细地质研究奠定了基础。Guide by the theories and methods of high-resolution sequence stratigraphy and sedlmentology, high resolution sequence stratigraphic classification and correlation are conducted in the Third Member of Funing Formation of Sha 7 block in Shanian Oilfield comprehensively applying the data of core, well logging and borehole log. According to the base-level cycles and accommodation changes, two grades base level cycles are identified in the area, among the rest, the upward-shallowing non symmetry and symmetry of three basic structure types of the short-term base-level cycles are mainly developed. Based on the identification of base-level cycles, the Third Member of Funing Formation is divided into three medium-term base-level cycles and seventeen short-term base-level cycles. The regional high-resolution se- quence stratigraphic framework of the Third Member of Funing Formation is established using cycle isoch- ronous correlation technology. This study is conductive to intensive geological studies such as the reservoir quality prediction and detailed description of reservoir structure.
