Abstract: Sichuan Basin is of multi-phase tectonic evolution，complicated structure styles，and complex hydrocarbon accumulation
conditions. Through analyzing the basic tectonic styles，trap styles of clastic and accumulation patterns of Sichuan Basin，
three main deformation zones can be found in Sichuan Basin：W–NW Sichuan foreland basin，uplift in Central Sichuan Basin，
and ejective fold in E–SE Sichuan. Hydrocarbon accumulation patterns in three deformation zones are different from each
other. Finally，the main reasons of three deformation zones are discussed in the paper，such as basement uplift，zonation differential
deformation，stratification differential deformation. The research is of the guiding significance for future hydrocarbon
exploration in Sichuan Basin.

Key words: tectonic style, differential tectonic deformation, accumulation pattern, Sichuan Basin
