SYSTEM-DYNAMICS SIMULATION OF HYDROCARBON-GENERATION OF COAL

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.
