Abstract: A basin may have a complex history of tectonic evolution, and it tends to be affected by tectonic inversion. The study of tectonic inversion means that tectonic inversion may control the development of oil-gas reservoir. Presently,the theory about remained basin predicts a new way for oil-gas exploration. The study of tectonic inversion will play an important role in the formation of oil-gas reservoir. This paper presents the definition,classification of tectonic inversion and its relationship with forming hydrocarbon reservoirs. Some examples are given to show this kind of relationship.

Key words: tectonic inversion, remained basin, oil and gas reservoir
