UNIT FOR TAKING SAMPLES FROM GAS-HYDRATE POOLS Russian patent published in 1995 - IPC

Abstract RU 2027003 C1

FIELD: mining. SUBSTANCE: unit for taking samples from gas-hydrate pools has body in form of thermal chamber of magnetic material with partition of nonmagnetic material installed for hydraulic communication of chamber parts in upper and lower ends. Secured to body is tubular member with rock disintegrating tool and membrane with a layer of abrasive material and channels. Besides, installed on body is preventer for rotation and axial motion. Thermal chamber may be filled with magnetic fluid. EFFECT: higher efficiency. 3 cl, 3 dwg
