Study on mechanical properties of gas hydrate-bearing porous media

摘要：

Gas hydrate-bearing porous media are natural or artificial porous deposits (soil sediments or coal) that contain gas hydrate in their pores. The mechanical properties of gas hydrate-bearing porous media are very necessary for researches on gas production and hydrate-based technology. This paper summarized the advances of the research on the mechanical properties of the gas hydrate deposit, from the experimental and numerical aspects. Also, this paper points out that research on the mechanical properties of synthesized gas hydrate porous media (coalbed seam) is necessary for coal and gas outburst prevention and mitigation. First, the theories about strength and deformation are introduced; second, a simple constitutive model for gas hydrate-bearing sediments is referred; third, the experimental and numerical researches are discussed; finally, this paper provides some suggestions for future study on mechanical properties of gas hydrate-bearing porous media.
