Low-density turbidite sequence was well developed in
Low Cretaceous in Zone 1 of Bonan Oilfield , Shandong
Province.Based on the core ,ten kinds of lithofacies which are
shale and sandstones ,nine kinds of lithofacies association and
four kinds of turbidite sandstone which includes sheet-like
turbidite sandstone , channel sandstone , inter-channel
sandstone and sandstone which formed correlation , facies
distribution were analyze. The reservoir can be divided into
three kinds of layers ,that is channelized type ,sheets-like type
and failures ,based on the facies and distrivution of sandstone
which formed the layer. The study of the barriers indicates
that the barriers between sand ests and in the sets are very
different . the barriers between the sets are thicker and more
widely spread than that in the sets.
