Abstract
A method for regulating and controlling a generated crystal form of a natural gas hydrate is provided. A mixture composed of a salt substance, a surfactant, a water-soluble thermodynamic additive and water is introduced in a generation process of the natural gas hydrate. The salt substance and the surfactant also have a synergistic effect with a water-soluble thermodynamic accelerator. The addition of the salt substance and the surfactant can change a local solubility of the water-soluble thermodynamic additive in water, so that the regulating and controlling process of the hydrate crystal can be realized, thereby improving a hydrate gas storage capacity and solving the problem of low natural gas storage capacity in the generated natural gas hydrate in a water-soluble thermodynamic additive system.
