| 摘 要： | 南海是西太平洋最大的边缘海,其在形成演化过程中出现了有利于生物礁生长发育的环境。东沙隆起在中新世时期属于浅海环境,远离物源区,温度、盐度和水深适宜生物礁的生长和发育。通过地震资料的解释、测井、岩心资料的综合分析,并与相对海平面变化曲线对比,认为东沙隆起发育大量规模不等的生物礁,且其发育演化与相对海平面变化曲线和区域构造演化阶段可以对应起来。相对海平面的旋回性变化和复杂的构造演化过程结合,使得研究区生物礁具有较好的孔渗性,可以成为有潜力的油气储层。

| Abstract: | The South China Sea is the biggest marginal sea in the West Pacific.The environmental conditions are favorable there to the growth of reefs.The Dongsha uplift was a shallow water area far from provenance in the Miocene.The marine conditions including temperature,salinity and water depth were excellent for reef growth.Base on the integrated study of seismic,well logging and core data,and taking into account of relative sea level changes,we believe that there were plenty of reefs developed in different horizons in the Dongsha area,due to the complicated cooperation of relative sea level change and regional tectonic evolution,which made the reef rocks good reservoir with high porosity and permeability. |
