【摘要】：作为当今全球油气勘探的热点领域,深水盆地发育于非火山型被动陆缘背景,其结构特征及演化过程与被动陆缘形成过程中岩石圈的变形作用密切相关。文中通过系统的文献资料调研,在总结非火山型被动陆缘研究现状和研究进展的基础上,阐述了非火山型被动大陆边缘的分类及其主要特征,详细介绍了非火山型被动大陆边缘演化阶段与构造单元的划分,从横向和纵向上描述了其深水盆地沉积特征,并简单探讨深水盆地构造-沉积演化过程。对非岩浆型被动陆缘研究进展及其深水盆地发育特征的总结,以期有助于深化对国内被动陆缘深水盆地结构特征和演化过程的认识,为深水油气勘探提供理论指导。
[Abstract]:As a hot field of global oil and gas exploration, deep-water basins are developed in the background of non-volcanic passive continental margin. Its structural characteristics and evolution process are closely related to the deformation of lithosphere during the formation of passive continental margin. On the basis of summarizing the present situation and research progress of passive continental margin of non-volcanic type, the classification and main characteristics of passive continental margin of non-volcanic type are expounded. The evolution stages and tectonic units of non-volcanic passive continental margin are introduced in detail, and the sedimentary characteristics of deep water basins are described both horizontally and longitudinally. The authors also briefly discuss the tectonic-sedimentary evolution process of deep water basin and summarize the research progress of non-magmatic passive continental margin and the development characteristics of deep water basin. It is expected to help deepen the understanding of the structural characteristics and evolution process of the passive continental margin deep water basins in China and provide theoretical guidance for deepwater oil and gas exploration.

【正文快照】： 自20世纪90年代以来,国内外深水油气勘探不断取得突破。世界上重大深水油气田多分布于大西洋被动陆缘两岸,就其地理位置分布规律不难发现,非火山型被动陆缘深水盆地是油气富集的有利场所。近年来,有关被动陆缘深水盆地的大量研究主要集中在伊比利亚的深海钻探和阿尔卑斯古特提
