摘要
通过对地震、测录井和岩心资料的综合分析,惠州地区珠江组地层陆架砂主要有潮控和浪控两种类型,分布明显受古地貌背景和水动力条件的控制;惠州地区珠江组地层陆架沉积成因类型有前陆架型、具水下凸起的局限海湾型、具镶边台地的局限海湾型和开阔陆棚型四种模式;陆架砂具有厚度薄、分布广、孔渗性好和侧向相变为陆架泥等优点,是地层岩性油气藏勘探的一个主要方向。
According to comprehensive researches on seismic,logging and core datum,this essay analyses distribution of Shelf sand in Zhujiang formation of Miocene in Neogene in Huizhou area of Pearl River basin.Meanwhile,this essay analyzes sedimentary genetic types of shelf sand and the relationship between shelf sand and sedimentary environments,and establishes sedimentary genetic models of shelf sand.It can be concluded that Shelf sand mainly charged with tidal and waves,and controled by the ancient background and ...
