根据封闭体系黄金管热模拟实验结果，应用Kinetics专用软件，研究了塔里木盆地库车坳陷中生界不同类型烃源岩的生烃特征与动力学参数。库车坳陷侏罗系煤、碳质泥岩、泥岩及三叠系湖相泥岩具有各自的活化能分布和频率因子，揭示出其生烃行为的差异性。利用GOR—Isotope Kinetics软件，推导了库车坳陷侏罗系煤、泥岩和三叠系湖相泥岩3类烃源岩的碳同位素动力学参数。上述参数的获取，为盆地模拟、烃源岩评价、生烃量计算及资源量预测提供了重要的基础地球化学数据。

Study of hydrocarbon generation kinetic parameters of Mesozoic source rocks in the Kuqa Depression, Tarim Basin

Based on thermal simulation data of gold tube experiment in the closed system and combined with the specfic Kinetics Software, the parameters of hydrocarbon generation kinetics from Mesozoic source rocks in the Kuqa Depression, Tarim Basin were studied. Jurassic coal, carbonaceous, coal-associated mudstone and Triassic mudsone in the Kuqa Depression are quite different on the activation energy distributions and frequency ratios. This demonstrates the differences on the behaviors of hydrocarbon generation from different source rocks. The parameters of carbon isotope kinetics from Jurassic coal, carbonaceous, coal-associated mudstone and Triassic mudsone in the Kuqa Depression were conducted using the GOR-Isotope Kinetics Software. These above stated kinetic parameters would provide the important geochemical data for basin modelling, the assessment of source rocks, the calculation of hydrocarbon-generating amounts and the predication of sources.
