Abstract

In this work, we consider the results of studying the natural gas hydrates formation in porous media saturated with fresh water and sodium chloride solutions of 5, 10, and 15 wt%. at a pressure of 8 MPa. The studies were carried out by the method of differential thermal analysis. It was found that the presence of salts in porous media reduces the degree of water conversion into hydrate, as well as the rate of the gas consumption in the process of the hydrate formation
