This paper, based on inter-well correlation and zircon U-Pb dating, suggested stratigraphic correlation schedule and 5 profiles across the Junggar Basin. The eastern Junggar Basin was filled in Carboniferous through two cycles and 7 steps. Then, the paper summarized the main characters of hydrocarbon source rock and reservoir rock and put forward a hypothetic prototype. In the eastern Junggar Accretionary Basin, hydrocarbon source rock and reservoir rock have intimate spatial links. Their interlayer or interfinger occurrence result in that oil-gas reservoir always form near hydrocarbon source, and that reservoirs themselves develop in various shapes and types because of irregular shape and poor layering of igneous rocks.
