Study on the Applicability of New Single Water Port PDC Drill Bit in Uranium Geological Drilling
The strata of uranium deposit in the northern region are mostly composed of sand and mudstone.In geological drilling,a large amount of solid components influx into the flushing fluid which seriously reduces the drilling efficiency and drilling quality.To overcome this problem,a new type of single nozzle PDC comprehensive drill bit was designed and its reliability was verified in terms of structure and materials through numerical simulation.Through on-site experimental research and comparison with traditional comprehensive drill bits,the new drill bit was verified faster in the actual drilling of mudstone formations,with the mechanical drilling speed by nearly 20%,and more preventable to serious drilling accidents.Therefore the new drill bit is of strong applicability in uranium geological drilling.
