DEVICE FOR PRODUCTION OF STEAM-GAS MIXTURE Russian patent published in 1997 - IPC

FIELD: oil and gas production industry. SUBSTANCE: device has compressor, compressor drive unit in the form of piston-type internal-combustion engine with exhaust manifold, water injection unit in the form of nozzle, and outlet pipeline. Compressor accommodates cylinder block located at angle to cylinder block of internal-combustion engine and similar to it with respect to number and dimensions of cylinders. Pistons of compressor cylinders are alternately connected by connecting rod mechanisms with common crankshaft. In compressor cylinder block, number of cylinders is multiple of 6, and half of these cylinders is united into first stage of compression and its inlet is connected to exhaust manifold and water injection unit. 1/3 of cylinders is united into second stage of compression, remaining cylinders create third stage of compression and its outlet is connected to outlet pipeline of device. EFFECT: high efficiency. 2 dwg
