Combined with geologic survey, drilling data and recent high-resolution seismic profiles, this paper analyzed the Cenozoic deformation characters of the Fushan-Keliayang area. The paper proposed that the studied area consisted of three ranges of structural belts from south to north, i.e. Fusha, Kekeya and Guman-Heshitag, of which the Fusha structural belt showed obviously lateral variations in configuration characters. Based on the balanced section calculation, the total shortening of the Cenozoic structural belts in the Fusha-Keliyang area accounted for 54.5 km and the shortening rate was 35.9%. Therefore, the Cenozoic deformation greatly controlled hydrocarbon accumulation, and deep structures of the Fusha structural belts were considered to be the best target for hydrocarbon exploration.
