Instruction
Hydraulic down hole hammer, on the base of rotating drilling, driven by the flushing fluid that output by the mud pump.
Its inside hammer give a fix frequency and energy to the bit, increase the speed of break rock.
In another word, the bit is a rotating drilling with impact burthen.
when drilling, the hydraulic hammer is between the bit and drilling rod or core pipe.
Under the impact and rotating, inprove the drilling efficiency, cost reduction, improve overall efficiency.
Application
Use for oil and natural gas well, to drill hard stratum, can increase 50% drilling time effect, suit for 5000m well drilling
