Abstract: Turpan-Hami basin, located in the southeasterm part of Junggar -Turpan ancient landmass, is a superimposed petroliferous basin with a long period of geologic development history. It is related closely to the evolution and formation of Bogeda parageosyncline rift belt for its northern part; to evolution of west end of north Tianshan mountain in narrow ocean and formation of collision foreland basin for its northwestern margin and southern part; and subjected to influence of movement between Siberia old plate and Xinjiang ancient landmass for its northeastern part. Marine and marine-continental altermating deposits are found in the Paleozoic, while continental deposits mainly in the Mesozoic. Two period uplifting movements of thermal ground anchor occurred in the deep crust-mantle of it, which forned plate tectonic conditions superimposed and enriched with two major hydrocarbon sources consisted of biogenic sediment and non-biogenie one. It is believed that Turpan-Hami basin is a medium-sized petroliferous basin with abundant oil and gas resources in its deep part.
