DEVICE FOR WELL THERMOMECHANICAL DRILLING Russian patent published in 2001 - IPC

FIELD: well drilling, particularly, thermomechanical drilling. SUBSTANCE: device includes drilling member, flame-jet burner, heat exchanger and adsorber, compressor and associated filter whose body is made in the form of jacket with air hollow formed by internal and external walls. Connected to filter body external wall are one pipe union for admission of heating air in bottom region and one pipe union for discharge of heating air in filter body upper part. In this case, pipe union for admission of heating air is connected by pipeline through controlled valve with pressure branch pipe of compressor, and pipe union for discharge of heating air is connected by pipeline through ejector with inlet of compressed air to heat exchanger. EFFECT: reduced energy consumption in well drilling by reduced energy consumption for production of compressed air. 1 dwg
