Abstract:

A thorough research of faulting features and structural types in the Tanzhuang Sag of the southern part of the North China Basin reveals that the Sag had developed more than 29 faults,of which the Yelv and the Shangshui are the southern and northern boundary faults of the Sag respectively and control the Sag and preservation of the Lower Cretaceous and Cenozoic there.The Sag contains four sets of source rocks with the Lower Cretaceous and Permo-carboniferous being the main source rocks and the Tertiary and Lower-Middle Jurassic being the potential source rocks.

Key words: hydrocarbon potential, structural feature, oil and gas exploration, Lower Cretaceous, Tanzhuang Sag, southern part of the North China Basin
