Abstract：This paper studies the tectonic setting,sedimentary filling characteristics and the petroleum geologic significance of the Early Carboniferous deposits in Dibei uplift,Junggar Basin,based on the datasets consisted of drilling,logging,seismic,paleontology,and geochemical data. It is suggested that during the Early Carboniferous Dibei uplift developed half-garben stretching rift and was characterized by the marine flysch and volcanic facies,which make it suitable for the occurrence of the hydrocarbon source rock. Based on the latest geochemical study of Well Quan 5,Dibei uplift has the source rock with high maturity,i.e. good source rocks. Such geological understanding breaks the original one that the Carboniferous source rocks of Dibei uplift is low-maturity and has no exploration potential. According to the mature exploration model of “near source and uplift controls”in Kalameili gas-field,this paper proposes two hydrocarbon accumulation patterns in Dibei uplift: “source and reservoir integration”and “near source and uplift controls”,which clears the favorable exploration zone.
