摘要: 根据吐哈盆地烃源岩和原油的生物标志物组成特征及系统油源对比结果,并佐以原油正构烷烃单体烃碳同位素资料,可将盆地原油分为三大类,即煤成油、咸水湖相泥岩成油和淡水湖相泥岩成油。为了进一步确定煤成油的主要烃源岩是煤岩还是煤系泥岩,在亚稳定状态下用GC-MS-MS研究m/z233--m/z262的二萜类化合物,并用其进行油源精细对比,认为吐哈盆地台北凹陷煤成油主要来自中侏罗统煤岩。

Abstract: Based on correlation between the system's oil source and the compositional characteristics of biological markers from hydrocarbon source rock and from the crude oils,associating with the data of isotope from each single component of the normal parafine series, the crude oil of Turban-Hami basin is divided into three groups, namely, the coal-formed oil, the salt lake mudstone derived oil, and the fresh lake mudstone derived oil. In order to further verify whether the coal-formed oil of the main hydrocarbon source comes from coal-bearing rock or from the mudstone of coal measure, the source rocks are correlated in detail upon the bi terpane series compound, and observed by GC-MS-MS study under sub-steady state in range of m/ z233--m/ z262. It is recognized that the coal -formed oil of Taibei depression of Turpan-Hami basin is mainly from the coal-bearing strata of Middle Jurassic.

Key words: coal-formed oil, oil-source correlation, isotope, crude oil type, Middle Jurassic, Turpan basin, Hami
