Abstract：Based on the sequence stratigraphic framework,combined with regional geology and results of former researchers,through analysis of data of heavy mineral combinations,lithology sequence of core,lateral change of lithology and logging curve‘s characteristics,seismic reflectors,sandstone thickness and content,the provenances of the Paleogene Oligocene Hetaoyuan Formationin in southeastern Biyang Sag of Nanxiang Basin were analyzed.The result showed that: There existed five provenances in Biyang Sag;The main provenance,Pingshi Provenance(Well B150-Well B285 area),controlled the southwestern sandbodies;The other four provenances are Yangqiao Provenance(Well B102-Well B239 area),Weizhuang Provenance(Well B151-Well B251 area)from the south,Liyuan Provenance(Well B129 area)from the southeast and the Lishuwa Provenance(Well B319 area)from the northeast. These minor provenances just influenced sedimentation of some sequences.
