摘要

摘要: 天然气生成的动力学参数的求取一直是天然气勘探盆地模拟技术中的难题。本文应用一套ＴＧＡ－ＦＴＩＲ（热失重与傅利叶红外光谱联用仪）对不同煤显微组分进行了分析，并将结果代入ｌｓｓｌｅｒ的最优化软件系统，求取这些组分的热解产物动力学方程，并对其热解性质进行了探讨。这些动力学方程可直接用于盆地模拟软件系统中，预测甲烷及其它产物的生成史。

Abstract: Kinetic parameters of kerogen pyrolysis have been widely used in basin modelling. Because the de-tection of gas products is more difficult than that of liquid products in thermal simulation experiments,the study of natural gas generation is random. The combination of TG( thermogravimetric)analysis with Fourier transform infrared(FTIR) spec-troscopy analysis was used to analyze different coal macerals and detect the pyrolysis products. The powdered samples were grogerssively heatedcatra to of 25℃/minute) and weighted in theT G A. A carrier gas transported the effluent through a multipass gas cell for continuos analysis by FTIRSelected infrared absorption bands were used to detect different compounds. Data were captured foraliphatics, aromatics, cardon dioxide and methane. The analytical results indicated that different coal macerals have different characters in pyrolysis. Hydrocarbon generation can be modelled by assuming that a number of parallel first grder reactions control the thermal decomposition of kerogen. Issler's optimization software was used to derive kineticparameters from the digitized pyrolysis traces. Kinetic solutions from TGA-FTIR data yield equations forspecial products. Inputting this equatioins into a numerical modelling package such as BASINMO D, alongwith other information, the generation of methane, aliphatics etc.coilld be predicted.
