摘要： 采用黄金管-高压釜封闭体系热模拟实验,结合专用Kinetics软件,对塔里木盆地库车坳陷侏罗系煤系源岩进行了生烃动力学研究,求取了甲烷、C2-C5气态烃生成的动力学参数。研究结果表明,库车坳陷侏罗系煤系源岩具有高的生气性,在高演化阶段主要产甲烷气;甲烷、C2-C5气态烃的生成活化能分别为43~64和52~72kcal/mol.生烃动力学方法可较好地将实验生烃数据外推到地质过程,在天然气评价与勘探中具有广泛的应用价值。

Abstract: By using thermal simulation experiment of closed system with gold tube-high pressure kettle, combined with special Ki-netics software, investigation of hydrocarbon generation kinetics of Jurassic coal-measure source rocks in Kuqa depression of Tarim basin is made, obtaining the related kinetic parameters of methane and C2-C5 gas hydrocarbons. The results show that the Juras-sic coal-measure source rocks are of good gas generation potentials and mainly produce methane at the high thermal evolution stage.The activate energy values of methane and C2-C5 gas hydrocarbons range from 43 to 64 kcal/mol and 52 to 72kcal/mol, respectively. The kinetics method of hydrocarbon generation allows well to extrapolating lab data to actual geologic process and thus can be widely applied to the assessment and exploration of natural gas.
