The Upper Guantao Formation of the Tertiary in Shenghai Region

Jiyang Depression is dominated by fluvial flood plain facies. Different scales of sequence cycles could be identified according to the cores

logs and seismic data of the formation.Short term base level cycles could be identified based on rock cores

intermediate term base level cycles could be identified through log seismic data correlation.Then the principle of the base level cycles was used to build high resolution isochronous stratigraphic correlation framwork

study the evolution proporty and the process of fluvial sequences

predict the spatial distribution of oil reservoirs.
