| 摘 要： | 以层序地层学理论为基础,综合利用地震、测井和钻井资料对额仁淖尔凹陷在下白垩统巴彦花群地层的层序地层学进行分析。通过对层序界面的识别和划分,认为额仁淖尔凹陷巴彦花群地层可划分为五个三级层序:SQ1、SQ2、SQ3、SQ4、SQ5。基于此,在各三级层序内部进行体系域划分及层序地层格架的建立,SQ1和SQ3为四元层序,低位体系域、水进体系域、高位体系域和湖退体系域发育完整;SQ2为缺乏高位体系域的三元层序;SQ4为二元层序,下部为水进体系域、上部为高位体系域;SQ5仅发育湖退体系域。

| Abstract: | Based on the theory of sequence stratigraphy, combined with seismic, logging and drilling data, the sequence stratigraphy of Bayanhua group of lower cretaceous in E＇ rennao＇ er depression is analyzed. Through the identification and classification of sequence interface, the formation of Bayanhua group in E＇ rennao＇ er depression can be divived into five tertiary sequences ： SQ1, SQ2, SQ3, SQ4, SQ5. According to this, system tract is divided and sequence stratigraphy framework is established in each tertiary sequence. SO1 and SQ3 are quaternary sequence, including lowstand system tract, transgressive system tract, highstand system tract and regressive system tract; SQ2 is ternary sequence without highstand system tract; SQ4 is binary sequence, the lower is transgressive system tract and the upper is highstand system tract; SQ5 is regressive system tract. |
