摘　　要：南沙海域第三纪盆地生物礁油气藏勘探具有巨大的潜力。作者运用层序地层学原理精细解剖不同体系域的生物礁内部构成 ,建立了高精度的生物礁礁层序地层格架 ,并逐层进行回剥分析 ,表明第三系充填沉积为四幕伸展裂陷过程 ,进而揭示盆地生物礁层序的动态发育过程及不同时期南沙海域含油气盆地的发育状态。The oil gas pools exploration of the Tertiary basins in marine area of the Nansha Islands had enormous potential. The interior structure of the organic reef of the different system tract was analyzed in this paper according to the sequence stratigraphy. The sequence stratigraphic framework of high grade organic reef was set up, and the development state of oil gas basins in marine area of the Nansha Islands was revealed for each period by the backstripping analysis technique for every sequence in the basins.
