Gas-extracting environment device for core gas extraction in natural gas hydrate drilling field

The utility model provides a gas-extracting environment device for core gas extraction in a natural gas hydrate drilling field. The gas-extracting environment device comprises a water-bath thermotank and a vibration table, wherein the water-bath thermotank is used for providing a thermostatic water-bath and is fixed on the vibration table; the vibration table provides vibration in a preset frequency and a preset amplitude for the water-bath thermotank. The gas-extracting environment device is capable of providing an isothermal and isotonic environment for extraction of core gas, and providing vibration conditions beneficial to release and collection of the core gas, thus when a gas-extracting tank containing a core sample is placed in the gas-extracting environment device, the uniformity of the gas release rate and the gas release degree of the core sample can be accelerated under the condition that the release gas of the core sample is not affected by the environment temperature, and the comparability of the
