摘要：

准噶尔盆地腹地为前寒武系结晶基底和泥盆、石炭系浅变质基底,分6个构造-沉积演化阶段,具5凸4凹共9个二级构造单元,下二叠统风城组、上二叠统下乌尔禾组和侏罗纪煤系为3套烃源层,有三套油气生储盖组合,莫索湾凸起、白家海凸起、三南凸起和中拐-达巴松凸起是有利的油气聚集区。

Abstract:

The basement of the hinderland of Junggar Basin consists of two layers,the Pre-cambrian crystalline and the Devonian-Carboniferous slightly metamorphic basement.From Permian to Quaternary,the hinderland experienced six structural-sedimental stages:1.platform marine basin;2.foreland marine basin;3.taphrogenic remnant marine basin;4.depressed continental basin;5.oscillation continental basin and 6.constriction continen-tal basin.Nine secondary structural units can be divided and Zhongguai-Dabasong,San-nan,Baijiahai,Muosuowan uplifts are favourable for hydrocarbon accumulation.The Permian Fengcheng(P1∫),lower Wuerhe(P2ω)Formations and the Jurassiccoal measures(J1+2)are source beds in the area.Triassic-Permian traps formed in lateHercynian—Indo-China epoch received mainly oil and gas from Permian source rocksand belong to allogenic type;Jurassic traps formed in early Yenshan epoch received oiland gas from Permian and Jurassic source rocks,and belong to autogenetic and combinedtypes.
