1.Introduction about us

We are Hejian Deris Petroleum Drilling Equipment Co., Ltd Drilling Supplies Marketing Dept. specializes in drill bits, drill pipe, Mud pump and stablizers for water well, oil field, construction, geothermal, directional boring, and underground foundation work all over the world. Our purpose is to sell the best quality products at the lowest possible price.

  We are a professional supplier of new and used(rebuilt) drill bits used for oil filed, water well. Including tricone bits, PDC bits and drill pipe. Various of model and dimension available. Good condition and reasonable price. We also import junk tricone bits and PDC bits.

2.PDC bit, also called PDC drilling bits

Polycrystalline Diamond Compact or called PDC -  These bits are expensive and used for very fast penetration mostly in shales.   This bit has carbide or man-made industrial diamonds set in fixed blades.  The cutters simply scrape the rock away during drilling, and do not rotate and grind the way the cones of a tri-cone bit do.

3.Deris PDC bits/ PDC bits

1) Be used for water well, oil field, underground, construction, geothermal, directional boring 2) Various of model and dimension available 3) High quality and competitive price 4) Improved support and retention, diamond are impregnated in the matrix behind the PDC cutters 5)Hejian Deris Drill Co., Ltd specializes in drill bits, tricone bits, PDC bits bit size range from 3 7/8"to 26", cover most of IADC codes.

(M122)

Soft and Medium Formation

Deep blade and short parabolic configuration ,ensure optimal bottom hole flow pattern and anti-balling .

Balanced flow hydraulics make the bit have good direction nature ,smaller radials are shaken .

Suitable for extremely soft to medial soft formation .

(M222)

  

Soft and Medium Hard Formation

Deep blade and long parabolic configuration ,ensure optimal bottom hole flow pattern and anti-balling .

Anti –whirl design improves ROP and enhances the drilling stability .

Arc blade and spiral gauge enhance the cutting capability and the drilling stabilization .

Medial cutter density design is suitable for soft to medial formations .

(M322)

Medium Soft and Medium hard formation

Deep blade and medial parabolic configuration ,ensure optimal bottom hole flow pattern and anti-balling .

Balanced flow hydraulics make the bit have good direction nature and enhances the drilling stability .

Medial and double row cutters design,suitable for medial soft to medial hard formations

  

5.Deris drill bits have these advantages

1. Short parabolic crown profile, medium cutter density. 2. Interchangeable screw nozzle. 3. Structured diamond/carbide interface. Cutter delays the onset of Fracturing and cutter wear. 4. Under-cut shank maximizes junk slot area for better bit cleaning. Hign filt nozzles for improved hydraulics and Rop. 5. Can be used on rotary or down hole motor. 6. Surfable for soft to medium formation.

7. High His is recommenced.
