摘　　要：煤成烃是目前国内外油气勘探的新领域，是油气地质研究新的热点和重点。本文基于煤成烃研究的最新成果，运用“系统论”的原理和“系统动力学”的工作方法，将煤生烃史系统划分为古温度和有机质成熟史、烃源岩发育史和有机质降解史等三个子系统。在泥岩生烃史模拟方法的基础上，建立了煤生烃史系统的系统动力学模型。模型的特点是各子系统内部及其间充满了控制和反馈控制信息。将该模型应用于辽河盆地东部坳陷荣兴屯地区的煤生烃史研究中，取得了令人满意的效果。Research on hydrocarbon generation of coal is a new hot point in the world now.According to the Principle of System theory and the methods of system Dynamics,the author built a hydrocarbon generation history system of coal based on the latest researches that includes three subsystems,namely,paleo temperature,sources rocks and metamorphosing of organic matter et al.Subsystems.Furthermore,the author also built a System Dynamics model of hydrocarbon generation of coal based on the present simulation of that of mud stones in this paper.The new model has one important feature,namely,it is full of messages of control and feedback control.In the end,The author designed a progam based on the new model and used it to study the characteristics of hydrocarbon generation of coal in Rongxintun area of East Liaohe basin,China.The results of the simulation are satisfying.
