By analyzing the regional stress, seismic profile and drilling data, the hydrocarbon distribution in different sags of Jiyang depression was studied based on evolution characteristics and superimposition of different trend faults controlled by regional stress, as well as the analysis of variance of accumulation elements. The results show that the Domino style orderly thrust folds are formed with the tectonic plates mergers in the period of Indosinian tectonic movement. The Domino type orderly structural inversion occurs under the control of sinistral strike-slip stress in Tan-Lu faults zone in the east and in Lan-Liao faults zone in the west in the period of Yanshan tectonic movement. The NE ＂ broom style＂ strike-slip movement occurs under the control of dextral strike-slip stress in the period of Yanshan-Himalayan tectonic movement. Therefore, NW, NE and NNE faults are orderly formed and superimposed. Controlled by the superposition of different faults, the sags are pulsatire extension. The stretching rate controls the accumulation elements in different sag. The main oil-bearing stratum gradually becomes newer from Paleogene to Neogene in the southwest-northeast area.
