| Abstract: | Northeast Sichuan basin is a Mesozoic-Cenozoic basin in the northern margin of the Yangtze plate which has a complex tectonic
background and hydrocarbon accumulation history. By means of the analysis method of wave processes, major cycles of sedimentary
wave process in this basin have been studied. The results show that there are five-order cycles corresponding to 760, 220,
100, 35 and 20 Ma respectively, two first-order sedimentary cycles (220 Ma) and four secondorder sedimentary cycles (100 Ma).
The authors find that the second-order sedimentary cycles are well matched with reservoir formation cycles through studying
the relationship between second-order sedimentary cycles and reservoir formation cycles, and divide three reservoir formation
cycles in this basin.
