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
