Special space gas liquid circulation drilling method and device

The invention discloses a special space gas liquid circulation drilling method and device. The special space gas liquid circulation drilling device includes a circulation system, a drilling system, a power supply system and a lunar vehicle matching the power supply system. The circulation system includes a guide pipe, a suction pump, a compressor, a cooler, a one-way valve, a seal ring, a support, a seal block, a seal bag, a liquid nitrogen filling rod, a liquid nitrogen filling chamber, a liquid nitrogen filling opening, a liquid nitrogen circulation inlet, a recovery cover, and a heat insulating layer. The drilling system includes a power device, a drilling rod, a drilling bit, and atomizing nozzles. The power supply system includes a power supply device and a wire. The gas liquid circulation drilling method and device is based on the practicality, and is skillful in auxiliary drilling manner; a liquid nitrogen vaporization heat absorption principle is used to help drilling, and the problem that the thermal conductivity is low during lunar drilling, and the drilling bit is prone to softening can be overcome; and the liquid nitrogen can be reused, and the cost is low.
