High-Resolution Sequence Research on Nearshore Subaqueous Fan System

ZHAO Jun-qing; JI You-liang; XIA Bin; REN Yong-jun; ZHANG Shan-wen

This paper discusses the high-resolution sequence in nearshore subaqueous fans sedimentary system, exemp lifying T85 nearshore subaqueous fans of the third middle member of Shhejie Formation in Shengbei fault's downthrown side ofDongying depression. The research shows that the high-resolution sequence stratigraphic units are divided into parasequence set, parasequence, bed set and bed in the fan-delta. Types and comparison methods of parase-quence and bed set are especially studied. The type of bed set is divided into Fu, Cu and Hu, and parasequence into Cu-Fu, Cu-Fu and Cu-Hu. Two comparison methods of parasequence are provided that are facies change paralleling to source area and incision perpendicular to source area and fourmodels of bed set which are correlation of overstacking,correlation of facies change, correlation of thin sandstone bed and correlation of similar changing of lithology
