生物礁储层是一种典型的油气储层, 具有非常大的油气勘探潜力。位于南海北部大陆边缘的琼东南盆地, 在形成演化过程中出现了有利于生物礁发育的环境。盆地南部深水区远离物源, 在构造演化过程中产生了较多的构造隆起, 在这些构造隆起的周缘适合生物礁的发育。通过地震资料解释认为, 琼东南盆地南部深水区发育有规模大小不等的生物礁, 而且这些生物礁的发育与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 have great potential in oil exploration. Qiongdongnan basin is located in the northern continental margin of South China Sea, with favorable environment for reef growth and carbonate development during the evolution process. The south deepwater area of Qiongdongnan Basin is far away from the provenance, and many structural highs have developed, which was favorable for reef development. Through seismic data interpretation, it is believed that different scale reefs have developed in the southern deepwater area of Qiongdongnan Basin. In addition, these reefs have great hydrocarbon potential, and the development reefs can be correlated well with the tectonic evolutionary stages.
