摘要
The Cambrian is principal oil-gas exploration horizon in southeast Sichuan.This paper deals with lithology and profile texture,sequence boundary and sequence subdivision marks based on outcrop,drilling core and logging data.The Cambrian is divided into 3 third-order sequences.Sequence stratigraphic framework of the Cambrian is established and relationship of eustacy with karstification is studied which is of importance to reservoir and weathered crust.
