摘　　要：基于75个泥岩岩屑样品,对南堡凹陷1号构造Es段烃源岩品质与生标特征进行系统评价。得出结论为:南堡凹陷1号构造Es段烃源岩为好、腐泥-腐殖与腐殖型、成熟烃源岩,品质较卓越;生物标志物特征显示低等水生生物与陆源高等植物贡献相当,为淡水沉积;沟鞭藻类在低等水生生物中占比中等,整体热演化程度较高,水体咸度范围较宽且差异较大。Based on 75 mudstone cuttings samples,the quality and source rock characteristics of Es1 member of No.1 Structure in Nanpu depression are systematically evaluated.The conclusion is that the source rocks of Es1 member of No.1 Structure in Nanpu depression are good,sapropel-humic and humic,mature source rocks with excellent quality;Biomarker characteristics show that the contribution of lower aquatic organisms is equivalent to that of terrestrial higher plants,which are freshwater sediments;Dinoflagellates account for a medium proportion of lower aquatic organisms,with a high degree of overall thermal evolution,a wide range of water salinity and great differences.
