摘要
Oils from intervals in the Chepaizi areas of Junggar basin are divided into two groups based on physical properties, chemical components, biomarkers and stable carbon isotope composition of the oils. The results of oil-sources division and correlation for these oils by making use of nitrogen compounds distributions are completely identical with those by density, viscosity, group composition and other biomarker parameters just mentioned above, indicating that nitrogen compounds could be used in oil-sources division and correlation. Finally, oil-pool forming model is established for the Chepaizi uplift. It is just next to sag areas with favorable structural location,and has abundant oil-gas resources.
