摘要
建立了一个半开放系统的生烃化学动力学模型及其煤成气的简化模型。在该模型中煤或干酪根首先降解为油和气,随以后成熟度的增加,源岩中未排出的石油裂解为气,在油所的形成过程中,伴随着油气的初次运移。该模型可用于任何沉积盆地中油气形成过程的数值模拟。实际应用时,可根据给定的化学动力学参数,选择模型和其中参数。
A new kinetic model of hydrocarbon generation and its simplified coal-generated gas model in a half open system is established, in which coal or kerogen is degrated into gas and oil, then the un-expelled oil in source rock is cracked into gas as the maturation increases, and gas and oil are expelled simultaneously during the formation of hydrocarbon. The model can be used to the numerical simulation of gas and oil generation in any type of basins by selection proper model and parameters according to given kinetic parameters.
