摘　　要：通过对白音查干凹陷烃源岩特征进行分析,明确了从都红木组二-三段、一段到腾格尔组和阿尔善组二段共有4套潜在的烃源岩,大多属于好烃源岩和较好烃源岩,而且体积巨大。都红木组一段烃源岩分布范围广、有机质丰度高、干酪根类型好,但成熟度低,对资源量贡献较小。阿尔善组二段分布范围小,但有机质丰度和成熟度高,对资源量贡献最大。The analysis of source rocks in Baiyinchagan Sag showed that there were mainly of four sets of source rocks in potential,the most of them were good and better source rocks with huge distribution volume.The source rock in the 1st member of the Duhongmu Formation is widely distributed with a high abundance of organic matter,the type of kerogen is good with low maturity,and it has less contribution to hydrocarbon generation.The 2nd member of Aershan Formation is less distributed with high abundance of organic matter and high maturity,and it has the greatest contribution to the hydrocarbon generation.

关 键 词：白音查干凹陷 烃源岩 有机质丰度 有机质类型 成熟度
