Description

technical field [0001] The invention belongs to the technical field of new energy development experiments, and in particular relates to a natural gas hydrate exploitation monitoring simulation device and method. Background technique [0002] Natural Gas Hydrate, also known as "combustible ice", is an ice, crystalline, supramolecular, and clathrate compound formed by water and natural gas in a specific high-pressure and low-temperature environment. Tundra, where marine gas hydrate resources are global. The salient features of natural gas hydrate are wide distribution, large reserves, high density, and high calorific value. 3 Gas hydrates can release 164m 3 methane gas. It is estimated that the total amount of natural gas hydrate resources in the world is converted into methane gas, and its organic carbon reserves are equivalent to twice that of the world's proven fossil fuels such as coal, oil and natural gas. Therefore, natural gas hydrate is regarded as an alternative e...
