| 摘 要： | 利用钻井、测井、地震、古生物及地化分析资料,研究了准噶尔盆地滴北凸起早石炭世构造环境、沉积充填特征及其油气地质意义。结果表明,滴北凸起早石炭世发育半地堑式伸展断陷,发育海相复理石建造并发育海底火山喷发岩,具备烃源岩的发育环境。泉5井最新的地化分析表明,该区烃源岩发育且成熟度高,为好较好烃源岩;这个结果改写了滴北凸起石炭系烃源岩成熟度低、无勘探潜力的认识。依据克拉美丽气田“近源隆控”的成熟勘探模式,提出滴北凸起发育“源储一体”和“近源隆控”2种模式,明确了有利勘探区带。

| 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. |
