南盘江地区二叠系有着丰富的生物礁 ,但如何准确地预测潜伏礁一直是该区对礁油气藏勘探能否取得突破的关键因素之一。从相对海平面升降对礁生长发育控制的角度建立新的生物礁成因分类 (进积礁、并进礁和退积礁 ) ,提出南盘江地区 (含十万大山盆地 )茅口期礁为由西向东进积的进积礁 ,长兴期礁为并进礁。据此推断 ,南盘江盆地有可能存在茅口期 (层位相当于Yabeina和Neomisellina化石带 )潜伏礁带 ,但存在长兴期潜伏礁的可能性不大。图 6参 6
The Permian in the Nanpanjiang area is rich in reefs. However, how to accurately predict the potential of reefs has always been one of the key factors in the exploration of the reefs in the area. A new classification of reef genetic factors (leftover reefs, reefs and reefs) is proposed from the perspective of relative sea-level rise and fall to the control of reef growth and development. It is proposed that the Maokou period reef in the Nanpanjiang area (including the Shiwandashan Basin) West into the east into the intake of the reef, Changxing reef into the reef. Based on this, it is concluded that there may be a latent reef in the Maokou period (corresponding to the Yabeina and Neomisellina fossils) in the Nanpanjiang Basin, but it is unlikely that there will be a latent reef in Changxing Period.
