high quality of PDC oil drilling bits - all types

ZM PDC oil drill bits

our products have widely application in coal mining, oil/gas field, geological exploration, water conservarcy, power engineering, etc, advanced pdc oil bit has used in various oil fields in China as well as other regions in the world, 1.optimally designed bit profile for drilling soft to medium hard formations, 2. cutting structure is force balanced, bit blade is asymmetrically designed, spiral blade and are also designed so that the load on bit is balanced so that resulting better stability of the bit, 3. multiply types of high performance pdc cutters are strategically arranged on the bit for improve the service bit life.4. drylaulic systerm of bift is optimized used the cfd technology to enhance the cleaning and cool effects of the bit as well as the ability to effiectively prevent bit from balling, 5. erosion on the bit face is efffectively prevented by utilizing hardfacing material of high erosion resistan and applying advanced base metal enchancement technology, 6. ports on bit is also optimally designed to prevent erosion of water courses inside bit.

tungsten carbide martrix pdc oil bit possesses high wear resistant and impact resistant , parabolic crown profile and maxmizes junk slot can clean bit better and prolong the bit working life : the main structure feat, applying drylaulic balance designed , renewal nozzles and reasonable locating angle can gain ideal fluid field in well bottom, full clean and cool cutter, non-symmetry blades arrangement enhance drilling well balance, optimization for cutter shape, slant angle, cutter numbers prolong the bit working life in combination with the high quality of pdc cutter, and improve rop and drilling efficiency, it can be used on rotary and down hole motor,
