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。
Coal hydrocarbon formation is the new field of oil and gas exploration at home and abroad, and is a new hot spot and focus of oil and gas geology research. Based on the latest achievements of coal formation research and using the principle of “system theory” and “system dynamics”, this paper divides the history system of coal-producing hydrocarbons into palaeoclimate and maturity of organic matter, development history of source rock and degradation of organic matter History and other three subsystems. Based on the method of simulating hydrocarbon generation history of mudstone, a system dynamics model of coal hydrocarbon generation history system was established. The model is characterized by subsystems and their control and feedback control information. The model was applied to the history of coal hydrocarbon generation in Rongxingtun area in the eastern Liaohe Basin, and satisfactory results were obtained.
