According to the oil-gas geochemistry and hydrocarbon accumulation geology theory, the light oil accumulation mechanism of Chepaizi uplift belt was studied. The results show that the light oils of the area mainly come from Jurassic source rocks of Sikeshu sag, some of which are from Cretaceous source rocks. In the mid-late Neogene period, the Jurassic source rocks are in hydrocarbon-generating peak. In the light oil formation, reservoir sedimentary rate is large, and hydrocarbon charging and expulsion efficiency are all high, and the dissipation amount is small, all of these factors are important reasons for rapid accumulation.
