南海诸盆地第三纪生物礁甚为发育,类型丰富,已渐成为今后南海油气藏勘探的重点目标。本文在不同的盆地中选取有代表性的、类型不同的生物礁体如台地边缘礁、塔礁、块礁等进行了层序地层分析,认识了不同类型礁体的层序发育状况和沉积体系域特征,以及海平面相对变化所引起的生物礁生长方式的变化等,对生物礁储集层特征以及与沉积体系域的关系也进行了研究。
The Tertiary bio-reefs in the South China Sea basins are well developed and rich in types and have gradually become the key targets for the exploration of the South China Sea reservoirs in the future. In this paper, we select the representative types of different types of reefs in different basins, such as the platform margin reefs, tower reefs, block reefs, etc., Conducted sequence stratigraphy analysis, understanding of different types of reefs, sequence development and sedimentary system Domain features, and changes in the reef growth patterns caused by the relative changes in the sea level, the relationship between the features of the reef reservoirs and the sedimentary system domains has also been studied.
