摘要： 南图尔盖盆地阿雷斯库姆坳陷烃源岩主要分布在中、下侏罗统，含腐殖-腐泥、腐泥-腐殖、腐殖三种干酪根类型，处于低熟-成熟、局部高熟演化阶段。该坳陷具凹陷、凸起相间排列结构，油气生于凹陷、储于凸起的现象较普遍。凸起上的油气来源于两边凹陷的多套烃源岩。而不同凹陷和层系间沉积环境、干酪根性质的差异和分布的复杂性更造成了油源区分的困难。通过资料分析，将原油甾烷划分为Ⅱ1、Ⅱ12、Ⅱ22、Ⅲ型等4种分布类型，三环萜烷划分为两大系列11种分布类型，用三环萜烷中的“未知峰”区分不同凹陷的烃源岩，用甾烷-三环萜烷分布组合落实烃源岩层位，成功区分了油源。

Abstract: The source rocks of Aryskum depression in southern Turgay basin are mainly in Middle?Lower Jurassic, which contain three types of kerogen, i.e. humic?sapropelic, sapropelic?humic and humic ones, being at low mature?mature and locally high mature stages. Aryskum depression has a structure in alternative arrangement of sags and swells, in which oil and gas generally occur in sags with multiple sets of sources rocks and store in swells. So the oil sources is difficultly distinguished by the difference and similarity of sedimentary environment and kerogen properties between the sags and the strata. According to the data analysis, sterane in the crude oil is divided into four distribution types of Ⅱ1, Ⅱ21, Ⅱ22, III and tricyclic terpane into two series with 11 distribution types. Using "the unknown peak" of tricyclic terpane to distinguish source rocks in different sags and using distribution assembly of sterane?tricyclic terpene to find out specific position of the source rocks, by which the oil?source distinguishing problem is successfully solved
