摘　　要：利用色谱一同位素质谱对松辽盆地青一段正构烷烃进行了单体烃的氢同位素组成分析.研究认为：松辽盆地青一段原油、烃源岩的氢同位素为-126‰～-248‰,具有典型的陆相沉积的特点;青山口组一段烃源岩的氢同位素为-180‰-235‰,与海相烃源岩的氢同位素范围相差甚远,因此不支持松辽盆地曾经海侵的观点.By means of chromatography-isotope mass spectrometry （GC-IRMS） , the hydrogen isotopic composi- tions in the single-molecule hydrocarbon of n-alkanes from Member Qing-1 in Songliao Basin are analyzed. The studies show that the hydrogen isotope values of the crude oil and source rocks in Member Qing-1 of Songliao Basin vary in the range of-126‰--248‰, which have typical continental sedimentary characteristics; The hydrogen isotope values from the source rocks in Member Qing-1 are in the range of -180‰ - -235‰ and they are far from those of the marine source rock, therefore the viewpoints of Songliao Basin transgressed is not be supported.
