摘要
本文运用高分辨率层序地层学的基准面旋回原理,以钻井、测井资料的综合研究为基础,对华池油田长3油层组进行短期基准面旋回层序分析,将其划分为向上“变深”非对称型、向上“变浅”非对称型与对称型3种基本层序类型和更多的亚类型。运用旋回等时对比法则对短期基准面旋回层序进行等时对比,并建立等时地层格架。最后建立了短期基准面旋回层序的分布模式。
The short-term base-level cyclic sequences in the third oil reservoirs of the Yanchang Formation in the Huachi Oil Field, Ordos Basin are examined on the basis of well logs and high-resolution sequence stratigraphy. These cyclic sequences may be divided into three types： ＂deepening＂-upward asymmetrical type, ＂shallowing＂-upward asymmetrical type and symmetrical type. The isochronous correlation for the short-term base-level cyclic sequences results in the construction of isochronous stratigraphic framework and model for the distribution of the short-term base-level cyclic sequences.
