造礁生物演化经历了六个主要发展阶段,具有全球性演化规律特征,其盛衰变化在南方礁丘的时代分布上反映较为醒目。早泥盆世至晚泥盆世早期,为生物礁发育的首次鼎盛期,已发现的礁体达97个,而至今尚未发现晚泥盆世晚期(法门期)的生物礁;二叠纪是第二次鼎盛期,已发现该时期的礁丘达148个之多,生物特性明显,而至今也尚未发现早三叠世时期的礁体。中国南方这一礁丘时代分布特征恰好与F/F和T/P两次全球性巨大生物绝灭事件相吻合。因此在南方寻找生物礁型油气藏时,除了应当重视本区构造演化的控制作用外,还应极大地注意全球性生物演化规律的控制作用。
Reef biological evolution has experienced six major stages of development, with global evolution characteristics, its ups and downs of the changes in the distribution of the Southern Reef Qiu reflect more striking. In the early Devonian to early Devonian, there were 97 reefs discovered during the first heyday of reef development, but no reef has been found in the late Devonian (Famen) so far. Permian is In the second heyday, it has been discovered that as many as 148 reef crests at this period have obvious biological characteristics and up to now no reefs in the Early Triassic period have been found yet. The distributional features of this reef hill age in southern China happen to coincide with the two huge global extinction events of F / F and T / P. Therefore, when looking for reef-type reservoirs in the south, besides controlling the tectonic evolution in this area, we should also pay great attention to the control of global biological evolution.
