Rapid thermal excitation of gas hydrate extraction method

The present invention provides a rapid thermal excitation gas hydrate mining method. 1) arranged in the drilling pipe nanopowders delivery system delivered to the gas reservoir layer, and aluminum is injected into the nano-surface gas reservoir layer; 2) ignite nanopowders; 3) so that the local temperature of the gas reservoir layer was raised to 2000K or more, natural gas is decomposed; 4) for injection into the reaction zone nano aluminum powder, sustained release of the reaction heat in the high-temperature region; 5) natural gas is driven at high temperature and high speed nanopowders flows; 6) is driven and generating hydrogen gas evolved at reflux, collecting conduit disposed in the recirculation zone, and the hydrogen gas return collection collection conveyor internet. The biggest shortcoming of the conventional heat shock method exploitation of natural gas hydrate is that the heat utilization rate. The present invention adopts nano-aluminum powder is reacted with ice releasing large amounts of heat, while the gas hydrate structure will be destroyed, the release of gas, effectively improve the thermal efficiency.
