Base on bore logs and seismic facies characters,the article establishs five criterias for judging sequence boundary of deep-water setting, and then the strata of middle-upper Miocene are divided into six third-order sequences, two second-order sequences in Nigeria deep-water setting areas. Base on two-component Constitution feature of deep-water depositional cycle, deltas and relative sea-level change in shelf area, Classic threefold division of systems tracts are classified as twofold division of systems tracts: allogenetic systems tract and autogenetic systems tract. Allogenetic systems tract starts from base level descending to early stage of transgression, and it mainly has gravity current deposits that are composed of mass transport deposits and turbidite fans. Autogenetic systems tract starts from middle-late stage of transgression to base level rising to the highest position, it mainly deposits pelagic and hemipelagic argillaceous sediments.And we also analysis controlled factors of sequence stratigraphy development, but due to the limited datum, it is difficult to predicate that one or even more factors determine sequence development for most sequences.
