This paper deals with the tectonic migration of various types of basins and the regu-larity of time-space distribution of oil and gas in the eastern China basins from the availa-ble geological, geophysical and drill data, and then a preliminary discussion is made onthe relationship between tectonic migration and oil and gas formation.
