摘要
尼罗河三角洲盆地形成主要与新特提斯洋的开裂和持续扩张作用密切相关,经历了中生代裂谷与被动陆缘发育阶段、前陆盆地阶段和走滑盆地3个构造演化阶段。三角洲盆地可进一步划分为北三角洲次盆、南三角洲次盆和近海–深水次盆3个次盆单元,总体上贫油富气,且大多气藏位于深水区。通过对尼罗河三角洲盆地构造演化与沉积充填、烃源岩、储层等石油地质条件的研究,分析了尼罗河三角洲盆地的含油气系统,指出了尼罗河三角洲盆地未来主要勘探方向:北部深水地区勘探程度低,是大型天然气田发现的主要潜力区;超深水区存在大型碳酸盐岩生物气藏的勘探潜力。
The formation of the Nile Delta Basin is closely related to the cracking and continuous expansion of the New Tethys Ocean, and has undergone three tectonic evolution stages: rift and passive marginal development stage, foreland basin stage and strikeslip basin stage. The delta basin can be further divided into three sub-basins: the north delta sub-basin, the south delta sub-basin and the inshore-deep water sub-basin. Generally speaking, the reservoir is lean and rich in gas, and most of them are located in deep water. Through the geological condition of oil research of the Nile river delta basin tectonic evolution and sedimentary and hydrocarbon source rock, reservoir, etc., the paper analyzed the petroleum system of the Nile Delta Basin, and points out the future main exploration direction: the exploration degree of the Nile Delta Basin north deep-water area is low, is the main potential area for the discovery of large gas fields. The exploration potential of large carbonate biogas reservoir exists in ultra-deep water area.
