摘　　要：以高分辨率层序地层学理论方法为指导,综合运用岩心、录井和测井等资料,对赤岸油田韦2断块阜宁组一段进行了高分辨率层序地层学研究。结果表明,该区阜一段由4个中期基准面旋回层序组成,并划分出17个短期基准面旋回层序,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划分的基础上,应用旋回等时对比技术进行了精细地层对比,建立了韦2断块阜一段高分辨率等时地层对比格架。该研究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。High resolution sequence stratigraphy has been studied for the first member of the Funing formation,Wei 2 fault block,Chian oilfield by using core,mud logging and well logging data.The result shows that the first member of the Funing formation is composed of four medium-term base-level cycles,which are subdivided into seventeen short-term base-level cycles.The short-term base-level cycles are mainly dominated by upward shallowing asymmetric and symmetric structures.Based on the classification of base-level cycles,fine stratigraphic correlation is conducted by using isochronous cycles correlation,and regional high resolution sequence stratigraphic framework is established for the first member of the Funing formation.This study is helpful to intensive geological studies such as reservoir quality prediction and reservoir structure description.
