Characteristics and hydrocarbon-generating potential of Carboniferous source rock in Tacheng Basin

摘要: 在塔城盆地野外露头和塔参1井钻井烃源岩发育特征与有机地化特征分析的基础上,探讨了石炭系烃源岩的生烃潜力。通过烃源岩岩性与有机质丰度分析认为,较好的烃源岩主要为泥质岩,其次为碳质泥岩和煤,上石炭统泥岩总体要好于下石炭统。烃源岩母质类型主要为腐殖型,具有倾气型特征。烃源岩演化程度普遍达到了高—过成熟阶段,但仍有一定的残余生烃潜力。应加强烃源岩主要分布区及其生烃史与盆地构造演化的匹配关系和成藏历史的研究。Abstract: Based on the analyses of generation and organic geochemical characteristics of outcrops in the Tacheng Basin and source rocks from well Tacan 1,the hydrocarbon-generating potential of the Carboniferous source rocks was discussed.According to the lithology and organic abundance of source rocks,mudstones were good source rocks while carbonaceous mudstones and coals were also favorable.The mudstones in the Upper Carboniferous were generally more favorable than those in the Lower Carboniferous.The organic material types of source rocks were mainly humus ones with gas-generating feature.Source rock evolution had entered the high-mature and over-mature stages,but there still existed residual hydrocarbon-generating capacity.Studies should be focused on the main distribution areas of source rocks,the relationship between hydrocarbon generation and basin evolutions histories,and the history of accumulation.
