摘要: 通过对吐哈盆地鲁克沁弧形带的构造演化、储集层展布及孔隙演变、油源对比、成藏期、稠油稠变机理等方面的分析, 认为吐玉克稠油油田形成于早侏罗世, 并具有良好的构造条件和储集条件;原油稠变原因除与二叠系烃源岩在低熟期生排的原油本身就比较粘稠有关以外, 更重要的是与厌氧细菌降解和轻质组分散失有关。指出鲁克沁弧形带是吐哈盆地前侏罗系稠油和稀油勘探的重要领域。

Abstract: On the basis of analyses of structure evolution, distribution and pore evolution of reservoir, oil-source correlation, reservoir formation time and thickening mechanism of viscous oil in Lǜkeqǜn arc-like belt, Turpan-Hami basin, it is considered that Tuyuke heavy oil formed in Early Jurassic, along with superior structure and reservoir quality; the thickening of crude oil is related with viscous oil expelled in low maturity period, and more importantly, with degradation of anaerobic bacteria and escape of light composition.Therefore it is reasonable to suggest that Lǜkeqǜn arc-like belt is an important target for heavy and light oil exploration in pre-Jurassic in Turpan-Hami basin.
