【摘要】：二叠系塔尔朗组为吐哈盆地一套主要生烃供烃层系,目前发现的鲁克沁油田,其油源证实来自该层系。对吐鲁番坳陷西部来说,研究二叠系塔尔朗组烃源岩生烃演化动态过程是探索油气成藏规律的关键。文中系统地研究了吐鲁番坳陷西部地区塔尔朗组烃源岩的生烃史,结合古构造研究分析,来探讨不同历史时期二叠系烃源岩的生烃演化特征。结果表明:吐鲁番坳陷西部二叠系受多期构造运动影响,可分为沉积间断型、后期再沉积型、持续沉积型等3种埋藏史类型;二叠系塔尔朗组烃源岩发育一次生烃型、持续生烃型等2种生烃史类型。生烃演化的精细研究,为精确寻找油气藏奠定了基础。
[Abstract]:The Talang formation of Permian is a set of main hydrocarbon generating and supplying layers in Turpan-Hami Basin. The oil source of Lukeqin oil field discovered at present is confirmed from this series.For the western Turpan depression, it is the key to study the hydrocarbon generation evolution of the source rocks of the Talang formation in the Permian system.The hydrocarbon generation history of Talang formation source rocks in the western Turpan depression is systematically studied, and the characteristics of hydrocarbon generation evolution of Permian source rocks in different historical periods are discussed in combination with paleotectonic analysis.The results show that the Permian in the western Turpan depression is affected by multiple tectonic movements, which can be divided into three burial history types: sedimentary discontinuity type, late redepositional type and persistent sedimentary type, and the source rocks of Talang formation of Permian have a secondary hydrocarbon generation type.There are two types of hydrocarbon generation history such as continuous hydrocarbon generation.The detailed study of hydrocarbon generation has laid a foundation for accurate exploration of oil and gas reservoirs.
