PDC Bits for Oil well drilling

 

◆Matrix Body PDC Core Bit 

1. MEDIUM TO HARD FORMATION DRILLING

    Medium short parabolic profile with medium cuter density and blade-style cuter layout helps to obtain ROP in medium hard formations with medium compressive and small hard layers.

2. HIGH PERFORMANCE CUTTER

    8mmhigh performance cutters promote drilling ability in formations with layers

3. DURASET GAUGE

    Super strong material promotes gauge wear resistance to provide long bit life.

Size available: 8-1/2”*4”

◆Natural Diamond Core Bit  

Features:

    Double core parabolic profile and heavy natural diamonds placement are designed for coring in the hard and abrasive formation. High grade and suitable size natural diamonds improve increase bit’s ROP and duration.

Applications:

    Application formation: Hard and compact formation with very high compressive strength and some abrasive layer. Rock type: Calcareous shale. Sandstone.

Size available: 215.4*105

 

◆Matrix Body PDC Drill Bit

1.SOFT TO MEDIUM AND HARD FORMATION DRILLING

    Short parabolic profile with lower cutter density helps to obtain better ROP in soft to medium hard formations with lower compressive strength and small hard layers.

    Parabolic profile with medium to lower cutter density helps to obtain better ROP in soft to medium formations with low compressive strength and small abrasive layers.

    Medium Parabolic profile with medium cutter density helps to obtain better ROP in medium hard formation with medium compressive strength and small abrasive layers.

     Parabolic profile with heavy cutter density helps to obtain better ROP and long life in hard dense formations with high compressive strength and small abrasive layers.

2. DURASET GAUGE

    Super strong material promotes gauge wear resistance to provide long bit life.

3.SPECIAL CUTTER LAYOUT

    Balanced force cutter layout combined with straight blade design to improve the bit stability.

    Balanced force cutter layout combined with backside cutter design to improve the bit life and impact resistance.

4. HYDRAULICS

    Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow.

    Big junk slot with balanced hydraulics design improves anti-balling ability within high penetration.

5. UNIQUE BACKRACK DESIGN

    The cutter’s back rake has been unique design, reducing the bit torque and increasing aggressiveness . 

6.UNIQUE BLADE DESIGN

    Curved blade design makes the bit work stability.

    Straight blade mixed with curved blade make the bit work stably.

    Size available:6”, 8-1/2”, 9-1/2”, 12-1/4”,16”, 17-1/2”

 

◆Steel Body PDC Drill Bit 

1. SOFT TO MEDIUM HARD FORMATION DRILLING

    Medium short parabolic profile with medium cutter density helps to obtain better ROP in soft to medium hard formations with lower compressive strength and small hard layers.

2. DURASET GAUGE

    Gauge cutter promotes gauge wear resistance to provide long bit life.

3. HYDRAULICS
