【摘要】：基于边界断层组合样式及演化特征的分析,利用新方法量化表征边界断层活动性特征,并从微观-宏观角度分析边界断层活动性对沉积的控制作用,最终建立基于断层活动性的沉积模式量板。结果表明:东营凹陷北带沙四期边界断层活动性自西向东具有弱—强弱交替—强的变化特征;微观上,边界断层活动性控制形成了稳定-富物源型、动荡-富物源型、稳定-贫物源型和动荡-贫物源型4种沉积环境;宏观上,边界断层活动性与沉积厚度呈正相关关系,与推进距离呈负相关关系;微观与宏观上相结合,可以建立基于断层活动性的沉积模式识别量板,明确边界断层活动性与陡坡带沉积演化的耦合关系。
[Abstract]:Based on the analysis of the style and evolution of boundary fault assemblage, the new method is used to quantify the characteristics of boundary fault activity, and the controlling effect of boundary fault activity on sedimentation is analyzed from the microcosmic and macroscopic point of view. Finally, a sedimentary model measuring plate based on fault activity was established. The results show that the fault activity of the fourth stage of the Shahejie formation in the northern belt of Dongying sag has the characteristics of weak-strong alternating strong and strong from west to east, and microscopically, The boundary fault activity control forms four types of sedimentary environments: stable rich source type, turbulent rich material source type, stable poor material source type and turbulent poor material source type, and macroscopically, the boundary fault activity has a positive correlation with sedimentary thickness. The sedimentary pattern recognition measure plate based on fault activity can be established, and the coupling relationship between boundary fault activity and sedimentary evolution of steep slope zone can be clarified.
