摘要: 探讨了准噶尔盆地南缘前陆冲断带的油气成藏组合后认为,该带烃源岩和储层发育,盖层封盖性能较好,并且具备形成异常压力封存箱的条件。根据成藏组合要素和发育匹配关系,将该带的成藏组合分为以侏罗系和二叠系烃源岩生、三叠系和侏罗系储的下部自生自储型,以及以侏罗系和第三系烃源岩生、白垩系和第三系储的上部下生上储型两大类,进而细分为二叠系—侏罗系深部组合、侏罗系中部组合和第三系上部组合3个亚类。通过对生储盖层演化历史分析,认为成藏组合发育的主要控制因素是烃源岩的发育程度、断裂构造、盖层和异常压力封闭,明确了准噶尔盆地南缘前陆冲断带上部下生上储成藏组合是最为有利的勘探组合。Abstract: It is discussed in this paper hydrocarbon plays and controlling factors in the fold-thrust belt of the Southern Junggar Foreland Basin.According to the study,there are excellent hydrocarbon source rocks,reservoirs and caprocks in the belt.Furthermore,the abnormal overpressure is in good sealing condition for hydrocarbon accumulation.According to the key factors and the matching of hydrocarbon plays,hydrocarbon plays in this region are divided into two types,namely the lower play with Permian-Jurassic source rock and Triassic-Jurassic reservoir,and the upper play with Jurassic-Tertiary source rock and Cretaceous-Tertiary reservoir.Furthermore,three hydrocarbon sub-plays are suggested,namely the lower Permian-Jurassic play,the middle Jurassic play and the upper Tertiary play.Main controlling factors for hydrocarbon plays in this region are hydrocarbon source rock,fracture,caprock and overpressure.The upper play with Jurassic-Tertiary source rock and Cretaceous-Tertiary reservoir is favorable for exploration.
