A developed mathematical model offers a study of methane-carbon dioxide replacement in gas hydrate through injection of liquid carbon dioxide into a porous stratum with final sizes. Depending on the parameters of injected carbon dioxide flow and depending on the stratum boundary conditions, the process of formation of the gas hydrate comprising carbon dioxide can occur through methane replacement in the gas hydrate or through the formation of zones with free methane and water. The critical diagrams are presented that map the conditions for both regimes.

液态二氧化碳注入多孔地层中天然气水合物中甲烷-二氧化碳替代方案的研究。

通过将液态二氧化碳注入最终尺寸的多孔地层中，已开发的数学模型可以研究天然气水合物中甲烷-二氧化碳的替代。取决于注入的二氧化碳流的参数以及取决于地层边界条件，包含二氧化碳的气体水合物的形成过程可以通过在气体水合物中的甲烷置换或通过形成具有游离甲烷和水的区域而发生。提出了绘制两个方案条件的临界图。
