摘要
从基准面旋回的层次界面和层次实体出发,讨论了基准面变化的层次性及不同层次基准面旋回层序的特点。以坪北油田长4+5-长6油层组为例,对不同层次基准面旋回进行了划分与对比,建立了不同层次基准面旋回地层等时对比格架,分析了地层格架内储集砂体的发育分布特点。
Based on hierarchical interface and bodies of base-level cycles, the hierarchy of base-level changes and characteristics of cyclical sequences of different base levels are discussed. By taking Chang 4 + 6-Chang 6 oil formations for examples, division and correlation of different base-level cycles are conducted, a framework of stratigraphic constant-time correlation of different hierarchical base-level cycles are established, and development and distributional characteristics of sandbodies within the stratigraphic framework are analyzed.
