The natural gas hydrate mining similar simulation pipeline includes a pipeline body, an isosceles triangular prism cavity, a sealing element and a mining well; the isosceles triangular prism cavity is formed in the pipeline body; the sealing element seals the isosceles triangular prism cavity; and the mining well is arranged on the outer surface of the pipeline body, and a hollow part is formed in the center of the mining well, one end of the hollow part is open, and the other end communicates with the isosceles triangular prism cavity. By means of the natural gas hydrate mining similar simulation pipeline, system and method, similar physical experiment simulation research on the vertical well actual mining process of natural gas hydrate can be carried out, and data support is provided for corresponding numerical simulation mining research.
Description
technical field [0001] The invention relates to the technical field of natural gas hydrate exploitation, in particular to a similar simulation pipeline, system and method for natural gas hydrate exploitation. Background technique [0002] The thickness of the gas hydrate stable zone is generally less than 200 meters, and the distribution range is generally more than one kilometer, so the basic shape of the gas hydrate stable zone is a thin disk. When vertical wells are used for on-site production of natural gas hydrates, multiple gas production wells are usually opened at different depths on a vertical wellbore. When natural gas hydrate is exploited through gas production wells, in the process of depressurization production, there will be near-well zone, middle zone and far-well zone with different temperature and pressure conditions and flow fields around the level of each gas production well. The zone and the middle zone are effective zones. Considering the low thickness...
