Scientific novelty
Formation of the lower section of an ice access borehole when penetrating a subglacial lake for research purposes. Simultaneously with stable borehole drilling, its cross-section is expanded, and the water rising into the borehole at the moment of lake penetration is heated. The creation of a vortex flow of heated water allows for the formation of smooth borehole walls of constant diameter. The layer of meltwater formed during thermal drilling serves as additional insulation between the lake water and the drilling fluid in the borehole. These advantages improve the overall technological standards of this process
Advantages
The developed thermal projectile fundamentally differs from known drilling devices designed for opening subglacial water bodies hidden by thick ice sheets, providing the possibility of rapid and effective opening of a subglacial water body from an access well filled with drilling fluid. During the process of opening the subglacial water body, conditions are created for the long-term preservation of the lower section of the well for the purpose of comprehensive research of the water body.
Commercial implementation
The thermal projectile relates to drilling technology for full-face drilling of wells filled with low-temperature liquid in thick ice massifs of the Arctic and Antarctic and can be used for melt-drilling with simultaneous or sequential expansion of wells in ice.
