摘要
根据层序地层学理论,综合应用测井、露头、岩芯及地震剖面等资料建立十屋断陷的层序地层格架。根据识别出的层序界面标志,十屋断陷深部断陷期可划出3个二级层序:初始裂陷期层序组、快速裂陷期层序组和裂陷萎缩期层序组。在裂陷期层序中可以划出5个三级层序,自下而上为:火石岭组层序、沙河子组层序、营一层序、营二层序和登楼库组层序。
According to the theory of sequence stratigraphy, it establishes the sequence stratigraphic framework of Shiwu fault depression according to well Logging, out crop and core data. The deep strata of Shiwu fault depression can be divided into three second-order sequences of initial rifting period sequence, rapid rifting period sequence and atrophic rifting period sequence according to the sequence boundary marks that have been identified. In these rifting period sequences, the deep strata can be divided into five third-order sequences.It including Huoshiling formation sequence, Shahezi formation sequence, Ying＇yi sequence, Yinger sequence and Denglouku formation sequence from the lower layer to the upper layer.
