Abstract Through analysis of rock pyrolysis, saturated hydrocarbon gas chromatography-mass spectrometry and vitrinite reflectance (Ro), the paper studies the abundance, types and maturity of organic matters in the source rocks of Jurassic Beipiao Formation from LLD1 well of Niuyingzi Basin in western Liaoning, and comprehensively evaluates the hydrocarbon generation potential. The results show the TOC is 0.75%-37.9%, averagely 11.68%, with the III- and II2-type of organic matters. The Ro values mainly range from 0.57% to 0.62%, averagely 0.60%, belonging to the low maturity stage. From the above, it is concluded that the Jurassic Beipiao Formation in Niuyingzi Basin has certain hydrocarbon generation potential.
