摘要
DivSummary" name="EnDivSummary">According to the approach of sequence stratigraphy and seismic sedimentary,the sequence framework and sand-rich sediment body of Hanjiang formation in the north slope of Baiyun sag in the Pearl River Mouth Basin were analyzed based on drilling,logging and seismic data.The result shows that the sequence SQhj1 can be divided into low standard system tract(LST),transgression system tract(TST),high standard system tract(HST) and falling stage system tract(FSST).The sequence SQhj2 can be divided into low standard system tract(LST),TST and HST.The LST of sequence SQhj2 can be divided specifically into two parts of LST1 and LST2.Two sand-rich sediment bodies were found in study area,including FSST delta whose sandstone riches in mouth bar and distal bar,and LST fan whose sandstone riches in low standard delta,basin floor fan and slop fan complex.The evolution of depositional sequence was influenced by geomorphology of basin,syndepositional fault and faulted slope break zone,sediment supply and sea-level change.
