PDC DTH Drill Bit
- Main features: High hardness, high wear resistance, and strong impact resistance
The full name of PDC drill bit is Polycrystalline Diamond Compact Bit. It is named after its core cutting element - Polycrystalline Diamond Compact (PDC).
Application :
Mainly used in oil and gas exploration and development, coal mining, geological exploration, quarrying , mining , water well etc
Core Features and Application Fields
Core features: PDC drill bits cleverly combine the ultra-high hardness and wear resistance of diamond with the excellent impact resistance and toughness of hard alloy. This enables it to achieve high drilling speed, long lifespan, and low drilling cost when drilling into soft to medium hard formations.
Application areas: PDC drill bits are mainly used for:
Oil and gas exploration and development: used for fracturing formation rocks and is a key tool for oil drilling.
Coal mining: used for drilling in areas such as water exploration, gas drainage, and roadway support in coal mines.
Geological exploration: suitable for coring geological exploration of soft to medium hard rock layers. With technological advancements, some new PDC drill bits have been able to be applied to harder and more complex formations.
DHD340-115MM PDC DTH BIT
The DTH drilling tools produced by company include two series of high wind pressure and low wind pressure, The shape ofcrown is mainly two-airfoil or multi-airfoil, and the end surface design mainly includes planar and concave-convex surfaces, Among them, the planar structure can make maximum use of the cutting surlace; the convex face is self-repairing and stable, and has greater impact on the forma-tion, which is suitable for hard rock; the concave side has a good anti-skew effect.
DHD340-115MM PDC DTH BIT
Company advantages
Long service life of drl ing bit: made ofaloy steel, its service life is longer and higher than that ofsimilar products
High dhilling e ficiency: the cutters are wear-resistant, making the drilling bit always sharp,thereby greally improving he foo tage speed
Stable drilling speed: the drilling bit crushes the rock with impact and shear
Good diameter prolection efect: bits has strong wear re: istance and good diameter protection perfor mance, which can make elicient use ofcutters
Head shape: planar, concave. convex
Cutter type: dome cutter, parabolic cutter, bullet cutter, sharp cutter
