Abstract: A methane hydrate production method comprising a step of performing a reservoir grouting process. The reservoir grouting process comprises: injecting a grouting agent into a frozen soil reservoir on the land or a seabed reservoir for targeting methane hydrate existing within sand particles of the target reservoirs; or injecting a filling material into cavities naturally or artificially occurred in a frozen soil reservoir on the land or a seabed reservoir for targeting methane hydrate existing within sand particles of the target reservoirs, and enabling a grouting body being constructed.
