摘要
以高分辨率层序地层学理论为指导，对泌阳凹陷安棚油田核三段IV油组21-23
（H3IV21-3）小层进行层序地层分析。在层序界面和地层叠加样式研究的基础上，在该层段识别
出2 个级次（1 个中期和6 个短期）的基准面旋回，进而以短期基准面旋回为单元建立研究层段
的等时层序地层格架，并以此在格架内讨论了研究层段的沉积演化规律。
Abstract
horizon of H3IV21 -3 in Anpeng Oilfield based on the high -
resolution sequence stratigraphy. After the sequence boundary
and stacking pattern of horizon were studied, 1 medium-term
base-level cycles and 6 short-term base-level cycles have
been identified. And short -term base -level cycles were
divided into three basic structure types. The reservoir
synchronous framework has been established. Then the
evolvement of the sedimentation was discussed in study
horizon.
