Slurry-driven underground traction system

The invention relates to the field of petroleum and natural gas development equipment, in particular to a slurry driving type underground traction system. The slurry-driven underground traction system comprises a slurry station, a slurry pump, a ground slurry control module, a slurry conveying pipeline and an underground wheel type tractor, wherein a slurry inlet of the slurry pump is communicated with the slurry station, a slurry outlet of the slurry pump is communicated with the ground slurry control module, and the two ends of the slurry conveying pipeline are communicated with the ground slurry control module and the underground wheel type tractor respectively; therefore, the slurry can be pressurized through the slurry pump, and the pressurized slurry serves as a power source of the underground wheel type tractor; the ground slurry control module is used for guiding the pressure and flow of the pressurized slurry in the underground wheel type tractor, so that the underground traction force and speed of t
