虎林盆地虎1井烃源岩评价及油源对比

对虎林盆地虎1井各层段泥岩地球化学指标进行评价,表明虎1井主要烃源岩层为虎林组一段和白垩系下云山组,两段源岩均为好烃源岩,源岩处于低熟到成熟阶段,具有较大的生烃潜力。通过原油与源岩的饱和烃色谱参数及生标化合物对比,发现虎1井原油为成熟原油,并具有陆相高等植物贡献生油的特点,与虎一段底部成熟烃源岩有较强的相似性,认为该井原油即来自于虎一段源岩。

Source Rock Evaluation and Oil-Source Correlation of Hu1 Well in Hulin Basin

By evaluating geochemical indicators of mudstone in every layer of Hu1 Well in Hulin Basin,it shows that the major source rock of Hu1 Well are the first segment of Hulin formation and the lower Yunshan formation,these two formations are both good,while in the stage of low-mature to mature,therefore they have great hydrocarbon potential.Through researching Saturate chromatographic parameters and biomarker compounds of the crude oil in this well,comparing with the source rock,it was found that the oil is mature,with the character of continental oil generation,and it is similar with the source rock in the bottom of hulin formation,so that the crude oil in Hu1 Well is from the source rock of E2-3h1 formation.
