Abstract: There are various types of deep layer turbidite fans in Paleogene Dongying Formation from Liaozhong structure
zone of Bohai Bay of China. These turbidite fans are the most potential play of oil & gas exploration. They were buried deeply，
and few exploration wells can be used. Their research of these turbidite fans must rely on seismic data. This paper studies
the two representative turbidite fans and their internal feature using polytype seismic attributes extracted from the seismic data
of the LD22–1 area. We analyze not only their geologic characteristic，but also the display feature in the different seismic
attributes，and the reason why they would show such feature from the physical and geological significance. Eventually，12
seismic attributes sensitive to the identification of turbidite fan are obtained.

Key words: seismic attribute, seismic sensitive attribute, deep layer turbidite fan, composite turbidite fan, vermicular reflection
