MATHEMATIC MODELS OF STABLE CARBON ISOTOPE COMPOSITION OF COAL-DERIVED METHANE AND THEIR APPLICATIONS
煤成甲烷碳同位素演化的数学模型与应用

In this paper different mathematic models are discussed, including the relationship models connected the stable carbon isotope composition with source rock maturation, distillation models based on Rayleigh expression and kinetic models, and a relationship diagram between instantaneous and accumulation carbon isotope composition linked to source bed maturity is proposed on the basis of other researchers, which can be used to roughly estimate the accumulation/loss history of coal-derived gas pool.
