摘　　要：利用气相色谱(GC)和气相色谱/质谱联机(GC/MS)检测了青海出露油砂沥青的烃类组成与分布。结果表明,其为陆源湖相有机质生成的原油经生物氧化降解形成的。由于所处的独特地理、地质环境,其生物氧化降解程度低,饱和烃含量甚高,分布规整,轻质组分很多,明显不同于其它地区的油砂沥青。鉴于其特殊的化学组成与分布,该油砂矿必须采用新的方式进行开采。The hydrocarbon composition and distribution of outcropping oil sand bitumen in Qinghai have been analyzed by gas chromatography (GC) and gas chromatography-mass spectrometer(GC/MS). The oil sand bitumen was formed by the biologically degraded crude oil which originates from terrigenous organic matter. As it occurs in the special geographic and geological environment, this oil sand bitumen has distinctive characteristics different obviously from those in other places. It possesses very high saturate content, regular normal hydrocarbon distribution and high content of light oil constituents, i.e., it is still in the stage of lower biological degradation. Based on these facts, a new mining system should be used.
