我国东南沿海海岸线长达一万八千多公里.水深二百米以内的大陆架面积为一百多万平方公里,自北而南分布着渤海、北黄海、南黄海、东海西部、东海东部(冲绳海槽)、台湾西部、台湾东部、珠江口、北部湾、莺歌海和西沙北海槽等以新生代为主的沉积盆地,环绕大陆呈弧形展布,斜列错开,自第三纪以来其构造发育、沉积模式和海水进退等都与全球板块构造活动和气候变化等有着密切的关系,本文目的在于阐明其形成发育历史的一些基本地质条件,以便为这些含油气盆地的类比和远景评价提供依据(图1)。
The coastline of the southeast coast of our country is over 18,000 kilometers long, and the continental shelf within 200 meters of water depth is over 1 million square kilometers. Bohai Sea, northern Yellow Sea, southern Yellow Sea, western East China Sea and eastern East China Sea (Okinawa) are distributed from north to south Trough), western Taiwan, western Taiwan, eastern Taiwan, the Pearl River estuary, Beibu Bay, Yinggehai and Xisha BeiHangtou dominated by Cenozoic sedimentary basins, distributed around the continent arc, oblique staggered, since the Tertiary The tectonic development, sedimentary model, and the advance and retreat of seawater are all closely related to the global tectonic activities and climate change. The purpose of this paper is to clarify some of the basic geological conditions that led to the developmental history of these petroliferous basins in order to provide analogy and long-term evaluation of these petroliferous basins Basis (Figure 1).
