摘要

A plane one-dimensional theoretical model has been considered and numerical solutions have been derived for the replacement of methane by carbon dioxide in a reservoir saturated with methane and its hydrate during carbon dioxide injection. The case in which the intensity of carbon dioxide hydrate formation is controlled by the diffusion of carbon dioxide through the hydrate layer formed between the stream of a gaseous mixture and a methane hydrate has been considered. The dynamics of the main process parameters and the flow rates of injected and exiting carbon dioxide and recovered methane has been studied. The effect of a diffusion coefficient and absolute permeability on the specific features of gas replacement has been analyzed.
