摘要
阐述了利用数值模拟手段研究天然气水合物生成、储积、运移和分解规律的方法与进展。回顾了近20年以来国内外研究人员在该领域的研究成果,包括两大类概念模型及多个天然气水合物数值模型,并根据所采用的概念模型不同,把数值模型分为3类:低通量模型、高通量模型和混合通量模型。经过详细对比各种模型后,认为基于多孔介质水动力学流动-弥散理论的水合物数值模型具有良好的合理性与适用性,能够揭示天然气水合物的生长行为。最后对天然气水合物模型的发展前景作出了预测。
Various models,including two conceptual models and several numerical models for gas hydrate formation,accumulation,transportation and dissociation,were reviewed in this paper.These models can be classified into three groups,namely,low flux model,high flux model and mixed flux model,according to different conceptual models.After careful comparison,the hydro-dynamical model from the transport-dispersion theory in porous media is recommended for their rationality and applicability.The model has the capability to reveal the growth behavior of gas hydrate.The development potential of gas hydrate modeling is also discussed.
