Abstract:The area from Di’nan arch to Fubei slope is located in the east of the Junggar basin which includes several old apophy-sis and is favorable to capture hydrocarbon since there are several hydrocarbon depressions with mudstone and coals of Jurassic, which leading to complex oil-source.The contribution of the coals to the oil of Shishugou and Tugulu through the hydrocarbon generating conditions is discussed in this paper.The Jurassic coal is scattered in the area with a thickness of mere 30 m.In addition,its maceral is generally composed of inertinite.The hydrocarbon supplying ability of the coal is relatively weak com-pared with that of the Jurassic mudstone.Comparison of the characteristics of biomarkers from the coal-measure source rock and crude oils indicates that the contribution from Jurassic coal-measure mudstone derived oil is relatively large.It is found that the Cretaceous oil comes from the Permian mudstone and the Jurassic oil comes from both Permian and Jurassic mudstones.
