The High-Resolution Sequence Stratigraphic Feature of Fuyu Oil Layer in Toutal Ilf Ield,Mao11 Block

On the basis of a comprehensive study of core and log well,taking the high resolution sequence stratigraphic theory as a direction,the detailed analysis on the subdivision of different orders of the base-level cycles in Fuyu oil layer has been performed and a corresponding high resolution sequence framework has been estab-lished in Toutai oilfield Mao11 block.Fuyu oil layer can bedivided 5 long,2 middle,7 short and 31 super-short base-level cycles.And each super-short base-level cycles corresponds single channel.
