利用等温密封热解实验技术及恒速升温热解实验与PY—GC分析技术的结合,本文分别建立并标定了原油中各族组分,即饱和烃、芳烃、非烃和沥青质成气的化学动力学模型。结果表明,原油中不同族组分成气的过程均可用平行一级反应描述,但不同组分在平均活化能及活化能分布上有明显的差异。各族组分在地史过程中成气的过程可由各自的化学动力学模型来描述。这将使原油成气过程的定量、动态描述成为可能。
Based on the combination of isothermal seal pyrolysis experiment, constant temperature pyrolysis experiment and PY-GC analysis technique, we have established and calibrated the components of each group in crude oil, namely, saturated hydrocarbons, aromatic hydrocarbons, non-hydrocarbons and asphaltene Chemical kinetic model. The results show that the processes of forming different gas components in crude oil can be described by the parallel first-order reaction, but there are obvious differences in the average activation energy and activation energy distribution of different components. The process of forming components of a group into gels during geo-history can be described by their respective chemical kinetic models. This will enable a quantitative, dynamic description of the gas-to-gas process.
