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。
Based on the analysis of tectonic evolution, reservoir distribution, pore evolution, oil source contrast, hydrocarbon accumulation period and thickening mechanism of thick oil in Luqinqin arc belt in Turpan-Hami basin, it is considered that the formation of Tuoyu heavy oil field In the early Jurassic, and with good tectonic conditions and reservoir conditions; except for crude oil thickening reason and Permian source rocks in low-maturity crude oil itself is relatively thick, and more importantly, and tired Degradation of oxygen bacteria and loss of light components. It is pointed out that the Luqqin arc belt is an important area for the exploration of heavy oil and heavy oil in the former Jurassic in the Turpan-Hami basin.
