摘　　要：在系统评价前第三系烃源岩的基础上,根据生物标志化合物指标对原油和烃源岩进行对比,考察渤海海域前第三系烃源岩生烃指标与邻近坳陷的差异与潜力。研究结果表明,石炭系—二叠系、中下侏罗统及白垩系下统三套地层是前第三系烃源条件较好的地层,具有很好的生烃潜力。渤海海域前第三系烃源岩对油气藏的成藏有贡献,Q构造沙一段原油源于白垩系烃源岩,而K构造原油为歧口凹陷成熟度较高的沙三段及中生界烃源岩。Based on evaluating pre - tertiary hydrocarbon source rocks, using the methods of organic rock science, pyrolyzation analysis and organic geochemistry, according to the contrast between biomarker compounds index and hydrocarbon source rocks, this paper discusses the difference and potentiality of hydrocarbon source index and the nearby sunken. The results show that carbonic - permian system, the lower Jurassic and lower cretaceous are layers with good condition. Pre - tertiary hydrocarbon source rock can make contribution to the forming into reservoir. Structure Q comes from hydrocarbon source rocks of Cretaceous, and structure K is hydrocarbon source rock in Mesozoic erathem with high maturity. It＇s mixture oil.
