Abstract:

Due to the complexity of geological characteristics and lack of available data,there is still no commonly accep-ted view of theoretical cognition on deep water marine clastic sequence stratigraphy.This article overviews recently well-known sequence stratigraphic models worldwide,including classic sequence stratigraphic model,sequence stratigraphic model built based on deep-water system classification,that built on deep water sediment architectural superimposition style,that built based on quartered system tracts and that built based on physical sedimentary interfaces.It emphasizes on analyzing approaches and ideas of different models,advantages and disadvantages as well as the application condition in the deep water sedimentary research.We also summarize the key issues such as source-to-sink process of deep water sedimentation and allogenic factors of sequence stratigraphy,base level changes of deep water,order division of deep water sequence stratigraphy and auto-cycle of deep water.A high resolution sequence stratigraphic analysis based on available data and limited by physical interfaces is proposed for deep reservoir research.

Key words: auto-cycle, physical interface, base level, marine, deep water, clastic rocks, sequence stratigraphy
