准噶尔盆地哈山地区发育有石炭系、二叠系、侏罗系等多套优质烃源岩，这使得确定各套含油层系原油的来源和油气成藏模式存在一定困难。在对研究区烃源岩评价的基础上，对烃源岩和原油样品的生物标志化合物特征进行对比分析，确定主要的烃源层。油源对比分析结果表明，侏罗系储层中原油来源分为两类：第Ⅰ类来源于二叠系烃源岩；第Ⅱ类主要来源于侏罗系暗色泥岩，可能混有少量来自二叠系的烃源油。二叠系储层中原油来源于二叠系本身烃源岩；石炭系储层中原油也来源于二叠系烃源岩。

High-quality hydrocarbon source rocks are widely developed in the Hassan area,Junggar Basin,Xinjiang.They include the Carboniferous source rock,Permian source rock and Jurassic source rock.This makes it difficult to locate the source of the crude oil from each oil-bearing series and the oil and gas accumulation pattern.Based on the evaluation of the source rocks in study area,this paper analyses the biomarker compounds of the source rocks and the crude oil samples and locates the main source rocks of the Hassan area.According to the analytic result of the correlation of oil with source, the crude oil in the Jurassic reservoir can be divided into two families.The crude oil of the first family originates from the Permian source rock.And the second one originates from the Jurassic dark mudstone,maybe mixing in a small amount of hydrocarbon source oil from Permian.The crude oil in the Permian reservoir mainly originates from the hydrocarbon source rocks of Permian itself.The crude oil in the Carboniferous reservoir also originates from the Permian hydrocarbon source rocks.
