Full-hydraulic dual-power combined type myriametre drilling machine

The invention relates to a full-hydraulic dual-power combined type myriametre drilling machine. The full-hydraulic dual-power combined type myriametre drilling machine is suitable for drilling petroleum wells, geothermal wells, power generation wells, coal field escape wells and the like. The full-hydraulic dual-power combined type myriametre drilling machine is provided with a dual-power dual-circulation top drive, a combined type dual-circulation drilling tool, a continuous gas supply system, a locating type pneumatic slips and a locating floating type pneumatic slips structure. The full-hydraulic dual-power combined type myriametre drilling machine has advantages of small volume, light weight, large hook load, advanced function, fast drilling speed and the like; the full-hydraulic dual-power combined type myriametre drilling machine is capable of matching with various drilling techniques to drill wells and drilling into a myriametre extra-deep well along with a pipe, and compared with a mud drilling technique, the drilling speed is improved by at least 20 times. Because the full-hydraulic dual-power combined type myriametre drilling machine drills along with the pipe, the well completion speed is improved by more than 30 times, and pollution is rarely generated.
