Abstract：Nanpu Structure 1 and Structure 2 have undergone multiple tectonic movements,and the relationships between main fractures and sand bodies are not clear.In order to clarify the law of sand accumulation and search for favorable reservoir development zones,we use seismic and drilling data to analyze palaeogeomorphology.Combining with inversion and other geophysical means,we establish a sedimentary model called "fault-channel transporting sand,slope-break-belt controlling sand" in the southern provenance.Based on our research,the following understandings are obtained:①Middle-deep faults controlled enriched sand bodies,NE strike-slip faults developed in the early Es period controlled the formation of ancient channels,and they became main passways for sand bodies to be transported and accumulated; ②Nearly EW strike-slip faults developed in the late Es period intersected with the early NE strike-slip faults formed slope break belts,and sand bodies were accumulated under the break belts.New discoveries in middle-deep tectonic-lithologic traps in Nanpu Structure 1 and Structure 2 are achieved based on our research,which provides a reference for the lithology exploration in braided river delta sedimentary systems of complex continental faulted basins.
