天然气水合物的物理性质是勘探和开发天然气水合物的重要基础.基于第七届国际水合物大会(IGGH-7)的交流成果,从水合物合成与分解实验、物性参数测量技术以及数值模拟研究等方面,总结了水合物声学、力学及渗透率、电学、热物理等物性参数的最新实验研究成果及其进展,并对今后的研究工作提出了一些展望和建议.“,”The study on physical properties of gas hydrate(NGH) has been a hotspot for years taking account of the exploration and exploitation of NGH.This paper made an overall review of the discussions at the 7th International Conference on Gas Hydrates(ICGH7) and tries to introduce the readers to the new achievements and progress of the experimental study of physical parameters of gas hydrate(i.e.the acoustics,mechanics,permeability,electrics and thermal physics),including the changes in physical properties in the process of hydrate formation and dissociation,the technique for measurement and numerical simulation of physical properties.Some comments and suggestions were put forward for reference and further studies.
