Abstract

A polar region drilling machine is provided; a crown block, a derrick, a pedestal, a solid control, a slurry pump, a drill rod rack, a slurry material room, and a storage tank are respectively placed in a corresponding insulation shed for single heat preservation; the insulation sheds are connected through fasteners including pin shafts, and low temperature resistant rubbers are employed to seal seams; the polar region drilling machine can fully seal and insulate all drill equipment and worker working zones; the temperature in the insulation sheds cannot be lower than 10 DEG C when outer environment is -60 DEG C, thus ensuring normal operation of the drill equipment, and workers can work in a relatively comfortable environment; in addition, the derrick is fully sealed and insulated so as to effectively prevent the problems that a hook block assembly may swing with the wind in a windy oceanic climate.

Description

technical field [0001] The invention relates to a polar drilling rig, which belongs to the field of oil and gas drilling. Background technique [0002] At present, due to the limitation of technical level, drilling rig equipment such as hydraulic valves, oil cylinders and high-pressure hoses can only meet the use requirements of the minimum ambient temperature of -45°C; the ambient temperature of the gear box, winch brake caliper and other drilling rig equipment is -45°C requirements for use cannot be met. [0003] The existing low-temperature drilling rig is to place the equipment that does not meet the requirements of the ambient temperature of -45°C in the heat preservation shed, and use a heater to heat it in the heat preservation shed. When the ambient temperature is -45°C, the temperature in the insulation shed can reach 5°C~10°C, so that the equipment in the insulation shed that does not meet the requirements for low-temperature use can operate normally. The equipme...
