| Abstract: | The study on the formation of gas hydrate in sediments is mainly summarized. Firstly, the formation mechanism and advances in bulk gas hydrate study, including nucleation mechanism, armor effect and memory effect etc., are briefly described. Secondly, the difficulty and advances in the formation of gas hydrate with low-solubility gases, such as methane, and the effects of chief factors, such as pore size, on the formation of gas hydrate in sediments are summarized. Thirdly, the major mathematical models on ... |
