尼日尔三角洲东部深水区构造特征及其形成机理
|
摘要
研究尼日尔三角洲东部深水区块发现,整个盆地从陆向洋具有3个大的构造分区:伸展拉张区、过渡区和挤压逆冲区。伸展区以大型同沉积断层伴生大量滚动背斜构造为特征,过渡区发育大量泥底辟构造,挤压区以复杂的逆冲叠瓦构造为主。通过分析形成机理,揭示东部深水转换带上M研究区构造特征,按构造的演化特征将该区构造分为泥底辟型、冲断-泥底辟混合型、逆冲型3种类型,提出研究区内的圈闭主要以构造-岩性圈闭为主,为尼日尔三角洲盆地深水勘探提供新的理论指导。
The Niger delta displays the classic, well-developed zones of a large delta province with an onshore to shelfal zone of growth fault-controlled depocenters, a well-developed belt of "shale diapirs" around the outer shelf-slope area, and a fold and thrust belt in the slope area. The upper extensional zone develops different loading and the subsequent formation of large growth fault, most of which are normal and listric. A middle translational zone is dominated by mud diapirs and shale ridges beneath the upper slope. The thrust belt is characterized by oceanward verging, commonly imbricated, thrusts and folds. On the basis of the structural characteristics, we analyze the forming mechanism of the structure. We reveal the structural characteristics of the M region on the conversion zone in Niger delta, and the structure of the research area is divided into three types, based on evolution and features. On this basis, it is proposed that the main traps in the study area are tectonic-lithologic traps. This paper provides new theoretical guidance for deep water exploration in Niger delta basin.
