On the basis of geochemical analysis of crude oil, this paper analyzed saturated hydrocarbon fraction, maturity and original source material of the crude oil. The oil in Ziniquanzi Formation and that in Qigu Formation are similar in geochemistry, and most of them are mature. The oil in Shawan Formation is different, and most of which is under\|mature. Oil sources are determined. Most oil in Shawan Formation comes from the source rock in Anjihai Formation, a little of the oil comes from the source rock in the middle and lower Jurassic. The oil in Ziniquanzi and Qigu Formations comes from the source rock in the middle and lower Jurassic.
Key words: Junggar basin; Sikeshu sag; Geochemical characteristics; Oil source.
