摘要: 在恒速升温热解实验和ＰＹ－ＧＣ分析结合的基础上，利用数学优化求解技术，建立并标定了台北凹陷煤有机质成油成气的化学动力学模型。结合我们近期报导的木栓质体成烃的动力学模型，定量计算了干酪根成油、木栓质体成油的理论剖面，并进一步定量探讨了吐哈盆地台北凹陷烃源岩评价中的生烃门限、木栓质的早期生烃及有机质原始生烃潜力和原始丰度的恢复等问题。Abstract: Based on the data obtained from the combination of constantly heating rate pyrolysis and PY一GCand by the method of mathematical optimum algorithm,the themical kinetic models of the oil and gasgenerated from the coal orgyi cmatter in the Taibei seg were constructed and calibrated in this paper.Combined with the chemical kinetical model of the hydrocarbon generation by suberinite that was report-ed recently,the theoretical profiles of oils generated from kerogen and suberinite were calculated quanti-tativ ely,and a number of problems on the sourec rock evaluation in the Talbei seg of the Turpan-Hamibasin, sucn as the early hydrocarbon generation from suberinite, recovery of the original hydrocarbon po-tential and original abundance of organic matter,as well as the threshold of hydrocarbon generation, werefurther studied quantitativdy in the paper.
