 Based on detailed field survey of oil sand outcrops at the top of the Middle Triassic upper Karamay Formation and on the bottom of Lower Jurassic Badaowan Formation in Tuziakeneigou on the northwest edge of Junggar Basin, the authors measured 11 single sand beds in the oil sand outcrop of upper Karamay Formation whose lithology is mainly grayish-brown pebbly coarse sandstone and medium-coarse sandstone, and identified 12 single sand beds. It is thus concluded that oil sand beds in Tuziakeneigou have good reservoir quality and oil-bearing property. Group composition of oil sand beds is mainly non-hydrocarbon and asphaltite, with only a small amount of saturated hydrocarbon and aromatic hydrocarbon, reflecting the serious degradation of oil sands.
