Matrix PDC Bit For Oil, Geothermal, Water well Drilling

Matrix PDC Bit For Oil, Geothermal, and Water well Drilling

The hardness of the PDC matrix bit is high and corrosive, so the PDC matrix bit has a long single life and high inlet, which is widely used in natural gas drilling and deep wells.

The PDC matrix bit is sintered with tungsten carbide powder, brazed on the tungsten carbide body with synthetic PDC cutters, and diameter retaining with artificial heat-stabilized polycrystalline diamond. The tungsten carbide body has high erosion resistance, wear resistance, high strength and good diameter retaining effect. The bit waterhole area can be designed according to the hydraulic parameters required by the drilling process, providing greater flexibility. The shape of the body can be designed according to the characteristics of the formation, and the change of the shape of the body is only required to change the mold without adding equipment.

What Steel PDC Bit can DrillMore provide?

DrillMore mainly provide PDC bits from size 51mm(2") to 216mm(8 1/2"), with 3/4/5/6 wings which is widely used in natural gas drilling and deep wells.

Advantages Of Steel Body Over Matrix Body PDC Bits

The entire body of the Steel PDC Bit is made of medium carbon steel and machined.The PDC cutting teeth are fixed to the crown of the drill by means of a pressure fit. The crown of the bit is surface hardened (sprayed with tungsten carbide wear layer, carburized, etc.) to increase its resistance to erosion. The main advantage of this type of drill bit is the simplicity of the manufacturing process. Steel Body Bits have a larger chip flute area, higher flank height and narrower flank thickness than tire body bits.

DrillMore produces Steel Body PDC bits with tungsten carbide dressing wear layer, which enhances the wear resistance and erosion resistance of the steel body PDC bit flanks; improves the hydraulic performance for drilling in soft strata, resulting in better chip evacuation; enhances the protection of cutting teeth; improves the reliability and erosion resistance of the bit; and combines the advantages of tire body bits and steel bits to increase the mechanical drilling speed.

The drill head is treated with the surface hardening process (spraying tungsten carbide wear -resistant layer) to enhance its erosion resistance. The advantage of steel body is that the manufacturing cost is low and easy to repair.
