Abstract
A deep-sea submarine gas hydrate collecting method and a production house for the first time, the collecting method comprises the steps of: determining an active methane leakage zone near a landward limit of a submarine gas hydrate stability zone, acquiring submarine methane leakage in-situ observation data, determining a methane leakage rate and evaluating its economy; mounting a production house on the seabed, opening a monitoring system after the mounting, monitoring the submarine methane leakage condition and hydrate generation progress in real time, evaluating a hydrate generation amount, and performing hydrate acquisition work; and rapidly processing the gas hydrate in the house by a gas hydrate collecting system of an offshore platform, and continuously monitoring the methane leakage condition. A large amount of methane leaked can be collected, thereof, the method has dual meanings of resources and environment.
