摘要： 准噶尔 盆地东部白家海一五彩湾地区处于多个生油凹陷交汇区，发育石炭系海陆交互相、二叠系平地泉组、三叠系小泉沟群湖相泥岩和侏罗系煤系地层等多套烃源岩。油气来自于多个生烃凹陷的多套烃源岩,具有先油后气、多期充注的特征。在石炭系塔木岗组、巴塔玛依内山组、三叠系烧房沟组、侏罗系八道湾组、三工河组和西山窑组均获得工业气流。东道海子北凹陷、昌吉凹陷深部位二叠系平地泉组烃源岩已达到成熟-过成熟阶段,对白家海凸起的天然气贡献较大;五彩湾凹陷石炭系滴水泉组、巴塔玛依内山组烃源岩已达到成熟阶段。白家海凸起天然气主要分布在生气中心附近,近距离运移聚集成藏,五彩湾凹陷以石炭系自生自储的天然气藏为主。

Abstract: Baijiahai-W ucaiwan area is in line intersection of multiple source sags in eastern Junggar basin, with multiple hydrocarbon sourcerocks composed of Carboniferous continental-oceanic interaction deposits, Permian Pingdiquan formation and Triassic Xiaoquangou group lakemudstone, and Jurassic coal measure strata. It is characterized by multi-filled oil in the early time and gas in the late time. Commercial gas flowis output from Carboniferous Tamugang formation and Batamayineishan formation, Triassic Shaofanggou formation, and Jurassic Badaowan, San-gonghe and Xishanyao formations. The source rocks in deep of north sag of Dongdaohaizi and Changji sag have been in matured-over maturedstage, which contribute much to gas reservoir in Baijiahai salient; while the source rocks in Carboniferous Dishuiquan and Batamayineishan for-mations in W ucaiwan sag have reached the matured stage. Natural gas in Baijiahai salient is mostly distributed near the gas-generated centerand by way of close distance migration and accumulation, form gas reservoir(s). W ucaiwan sag is dominated by gas reservoirs with both sourceand reservoir in Carboniferous system.

Key words: Junggar basin, source rock, source sag, natural gas, hydrocarbon accumulation
