摘要： 准噶尔盆地中、下保罗统煤系地层中的泥岩和煤岩均具有良好的生经潜力,已发现的保罗系油气藏中的经类可能主要与煤系地层中泥质泾源岩有关从汹源角度分析，保罗系泊藏可分为下源型和自源型，前者主要分布在盆地北部。后者主要分布在盆地南部。形成纯气藏的生物气、过熟裂解气均分布在盆地南缘山前构造带。

Abstract: Mudstone and coal-seam of coal measu re strata possess bet ter hyd roca r bon generation potential in Middle and Lower Jurassic of Junggar basin; hydrocarbon in Juras-sic reservoir is related with mudy source rock of coal measu re strata. From oil source, Jurassic reser voir can be divided into "old genetic and new reserve" type and aut higenic type. The former mainly distributes in north part of Junggar basin, the latter in south part, biogas and pyrolysis gas to form gas reservoir are all in piedmont structural zone in south margin of Junggar basin.
