摘　　要：针对川北地区二、三叠系礁、滩气藏的烃源条件,通过烃源对比分析认为,二叠系是该区礁、滩气藏的主要烃源层。在川北地区二叠系有形成自源油气藏的条件,下三叠统飞仙关组生烃条件较差,其油气主要来自下伏烃源层,但在川北的东部地区具有一定的生烃能力,对飞仙关组油气藏的形成有一定的贡献。For source rock in Permian and Triassic reef and shoal gas reservoirs in northern Sichuan Basin, a correlation analysis illustrates that Permian, with a condition of forming self-source gas reservoir, is the main source rock stratum. For Lower Triassic Feixianguan Formation, the hydrocarbon-generating condition is very poor, oil and gas comes from the underlying source rock stratum. But Feixianguan Formation in east of northern Sichuan Basin has a certain hydrocarbon-generating capability and contributes to forming a gas reservoir.
