干酪根的性质对油气形成影响的研究 总被引：1，自引：0，他引：1
为了研究干酪根的性质对油气生成的影响,本文选择了三类不成熟生油岩样品进行了系统的人工加热模拟实验。研究表明,Ⅰ型干酪根有很高的产烃率,其中的无定形组分在向石油转化的过程中,首先经历了一个“沥青化”阶段,于酪根进入生油门限的早晚取决于生油期降解所需的活化能。 相似文献

The comparative study of organic matter in carbonate rocks and argillaceous rocks from the same horizon indicates that the organic thermal maturities of carbonate rocks are much lower than those of argillaceous rocks .Ana extensive analysis of extracted and inclused organic matter from the same sample shows that inclused organic matter is different from extracted organic matter,and the thermal maturity of the former is usually lower than that of the latter in terms of biomarker structural parameters.It seems that carbonate mineras could preserve organic matter and retard organic maturation.The inclused organic matter,abundant in most carbonate rocks,will be released from minerals and transformed into oil and gas during the high-thermal maturity stage. 相似文献
