Product Description

Product Description

PDC Drill Bits ((Polycrystalline Diamond Compact) Drill Bits) are widely used in the oil, gas, and mining industries for drilling operations, primarily due to their high efficiency, durability, and cost-effectiveness. These bits are made by bonding a layer of polycrystalline diamond (PDC) to a tungsten carbide substrate, which enhances the drill bit's ability to cut through hard rock formations. 
PDC Drilling bit is made by PDC cutters brazed to Steel Body or casing steel body. The PDC cutter has high hardness, abrasion resistance and toughness, the PDC Drag Drilling bit life is 20-40 times, and the drilling efficiency is 50% higher of tungsten carbide drill bit.

PDC Drag bit is applied to rock formation f below 12, like sandstone, mudstone, etc., it is mainly used for Coal mining ,water well, geothermal well, geological exploration, borehole, gas drainage hole, discharge water hole, blast hole,etc. There are several kinds of PDC drill bits, such as Concave Drill Bits, Anchor Drill Bits, Drag Drill Bits, Core Drill Bits. 












 

Application

• Oil and Gas Industry:

  • Exploratory Drilling: PDC bits are commonly used for drilling exploration wells, especially in hard rock formations, as they offer high drilling efficiency and longer bit life.
  • Production Wells: PDC bits are also used in the drilling of production wells, where drilling efficiency and bit longevity are critical.
  • Directional Drilling: PDC bits are suitable for directional and horizontal drilling due to their ability to maintain a steady cutting rate and reduce vibration.

• Mining Industry:

  • Hard Rock Drilling: PDC bits are ideal for drilling in hard, abrasive rock formations, such as granite, basalt, and quartzite. They are used in underground and surface mining operations to extract minerals.
  • Blasting Hole Drilling: PDC bits are used in creating blasting holes in mining for explosives placement. Their efficiency in cutting through hard rock reduces the overall drilling time.

• Geothermal and Environmental Drilling:

  • Geothermal Wells: PDC bits are also used in the drilling of geothermal wells, where extreme conditions, such as high temperatures, demand the use of durable and heat-resistant bits.
  • Environmental Drilling: PDC bits are used in environmental and geotechnical drilling applications due to their precision and efficiency.

• Construction Industry:

  • Foundation Drilling: PDC bits are employed for drilling foundation piles in construction, particularly in rock or hard soil conditions.

 

Our Advantages

Characteristics of PDC Drill Bits:

1. Composition:

   • Polycrystalline Diamond (PDC): PDC bits have a layer of polycrystalline diamond material. The diamonds are bonded together in a high-pressure, high-temperature process, forming a tough, wear-resistant material.
   • Tungsten Carbide Substrate: The base material of PDC bits is usually tungsten carbide, which provides strength and durability to the bit while being able to withstand high pressures and temperatures.

2. Hardness and Wear Resistance:

   • Superior Hardness: The polycrystalline diamond layer provides exceptional hardness, which makes PDC drill bits ideal for drilling through hard rock formations.
   • Wear Resistance: The hardness of PDC makes it resistant to wear and abrasion, allowing the bit to last longer in challenging conditions compared to traditional steel or roller cone bits.

3. Efficiency:

   • Higher Rate of Penetration (ROP): PDC bits can typically achieve a faster drilling rate due to their cutting efficiency. The sharp diamond edges efficiently shear through rock formations, improving the rate of penetration (ROP) compared to other types of bits.
   • Smooth Cutting Action: PDC bits are known for their smooth cutting action, which minimizes vibration and reduces the risk of bit damage, leading to more efficient drilling.

4. Cutting Structure:

   • Fixed Cutter Design: PDC bits use fixed cutters, which means that the cutting elements (diamond inserts) do not rotate. This allows for more precise cutting and reduces the likelihood of the bit slipping or skidding.
   • Multiple Cutting Faces: PDC bits often feature several diamond-impregnated cutting faces, which allow for more consistent cutting across different types of formations.

5. Thermal Stability:

   • Heat Resistance: PDC bits can withstand high drilling temperatures, making them suitable for deep drilling operations where heat is a concern. The heat resistance comes from the synthetic diamond layer, which maintains its properties under extreme conditions.

6. Cost-Effectiveness:

   • While PDC bits may have a higher initial cost than conventional drill bits, their superior performance and longer lifespan often make them more cost-effective in the long run. The reduced need for frequent bit replacements leads to lower operational costs.

7. Size and Design Flexibility:

   • PDC bits come in a wide range of sizes and designs to accommodate different drilling operations. They can be customized with different configurations of PDC cutters based on the specific formation or geological conditions being drilled.
