基于LBM方法的天然气水合物沉积物中多相流动规律研究
Study of multiphase flow laws in sediment with gas hydrate based on LBM method
摘要
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 flow field distribution of single-phase flow in porous media is related to the pore diameter (saturation) and permeability. The permeability of porous media decreases greatly due to hydrate formation in sediment.关键词
