Abstract
A riser stub for acoustic resonance decomposition of hydrate in deepwater drilling, comprising a through tubular stub body, a plurality of acoustic transducers being fixedly disposed on an outer wall surface of the tubular stub body; an outer side of the tubular stub body being covered with a water insulation layer, the plurality of acoustic transducers being sealed between the tubular stub body and the water insulation layer, the water insulation layer being further provided with a power-on interface that can be connected to a power supply, the plurality of acoustic transducers being connected to the power-on interface. A riser stub for acoustic resonance decomposition of hydrate in deepwater drilling, through continuous power-on, sound waves close to a simple harmonic vibration frequency of the hydrate are generated inside the pipeline to cause the hydrate in the riser to resonate, thereby being able to effectively avoid formation of hydrate inside the pipeline; after the hydrate is formed inside the pipeline, the acoustic transducers of the riser stub are energized, by means of the acoustic waves, the hydrate blocking the pipeline is caused to resonate to break its equilibrium state and to be decomposed so as to realize de-blocking.
