摘　　要：生物礁及碳酸盐岩储层是一种典型的油气储层,具有巨大的油气勘探潜力。我国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及碳酸盐岩发育的环境。琼东南盆地南部深水凹陷远离物源,在构造演化过程中产生了较多的构造高点,在这些构造高点的周缘适合生物礁及碳酸盐岩台地的发育。通过地震资料的解释及海平面变化曲线与层序的对比发现,琼东南盆地南部深水凹陷发育有规模大小不等的生物礁和碳酸盐岩台地,而且这些生物礁和碳酸盐岩台地的发育与海平面变化曲线和构造演化的阶段可以对应起来,应具有较好的油气勘探潜力。As an important hydrocarbon reservoir, reefs and carbonates have great potential in oil exploration. The South China Sea is the biggest marginal sea in the West Pacific and its evolutionary process sup- ply proper growing environment to the reef and carbonate. The south deepwater sag of Qiongdongnan Ba- sin away from the provenance developed many structural highs on which reef and carbonate platforms were greatly developed. With the seismic profile and the comparison between the eustatic sea level change and sequence, the authors find that there developed different scales of reef and carbonate platforms in the sag. These reef and carbonate platforms have many developing stages which can be correlated with the eustatic sea level change and evolutionary stages, besides, they all have preferable hydrocarbon potential.
