| 摘 要： | 根据沉积物中水合物分解过程中流体运移和孔隙介质的特点,提出将格子Boltzmann方法(LBM)用于天然气水合物沉积物中多相渗流规律研究的新方法,该方法是介于宏观和微观之间的介观模型方法,是用格子Boltzmann模型对多孔介质中水合物生成、分解过程中饱和度的变化影响多孔介质渗透率的特性进行模拟.模拟结果表明,多孔介质...

| Abstract: | According to the fluid migration and pore medium characteristics during decomposition process of gas hydrate in sediments,the lattice Boltzmann method(LBM) used in multiphase flow law study in sediments with natural gas hydrate was proposed.The method is for the mesoscopic model between the macro and micro.The effects of saturation change on characteristics of hydrate permeability were studied using lattice Boltzmann model for hydrate formation and decomposition process in porous media.The results show that... |
