In order to reveal differential enrichment of hydrocarbons in the central structural belt in the west of Bozhong sag,this paper systematically studies characteristics of paleo-uplift,fault activity,configurations of faults and sand bodies and fault lateral sealing. The main controlling factors of hydrocarbon accumulation are summarized. Results show that the paleo-uplift controls the macroscopic distribution of oil and gas,oil and gas plane accumulation degree are controlled by the hydrocarbon gathering efficiency of paleo-uplif. The oil and gas accumulation horizon are controlled by the fault activity,when the fault throw was greater than 150 m,the fault activity rate was greater than 10 m/Ma,the fault growth index shows the gradually-declined-turned acted type and linear rising type,the oil and gas were mainly concentrated in Minghuazhen formation. However,in Guantao formation,the configurations of faults and sand bodies control the oil and gas accumulation in Minghuazhen formation,and the compound type has a higher oil and gas migration efficiency. The oil and gas accumulation in Guantao formation are controlled by the lateral sealing conditions of faults. When SGR is greater then 0. 3,the fault has a better lateral sealing. Finally,the paper established an oil and gas enrichment mode of " paleo-uplift and fault jointly control reservoirs and differential accumulation" in research area,which serves as an effective guidance to the exploration deployment of oil and gas exploration in western of Bozhong sag.
