Qin Yanqun, Ji Zhifeng, Wan Lunkun, et al. Theory progress and key issues of deep water marine clastic sequence stratigraphy[J]. 2017, 38(1): 12-21.DOI: 10.11743/ogg20170102.
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.
