PDC bits uses PDC as main cutting components, with the excellent wear-ability and impact toughness of the PDC. It has a long useful life, high-efficiency, and good cost performance.
PDC bit is mainly used for drilling soft and big drainage.
PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure. It possess of high wear resistance like diamond, at the same time the impact resistance like tungsten carbide and that’s made it the best material as a drill bit cutter. Reinforced PDC has higher dense diamond powder, claw tungsten carbide substrate made the two layers solid as whole one. So, the reinforced PDC of supper wear resistance, longer service life and high efficiency.
PDC (polycrystalline Diamond Compact) drill bit is a new product after the hot-pressed and electroplated drill bit in recent years. With special high-frequency welding techniques, PDC of high wear resistant is welded to the body as cutting edges. PDC bit is mainly used for geological prospecting coal exploration, water conservancy and power engineering, etc.
1. PDC cutters for high speed drilling;
2. All cutters are premium grade for extended bit life and durability;
3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl;
4. Large junk slots and flushing ports;
5. Advanced geometric design for faster penetration;
6. Gauge pads have tungsten carbide inserts for maximum wear resistance;
Structure features and applications of the bit
1. Optimally designed bit profile suitable for drilling medium formation.
2. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced which resulting better stability of the bit.
3. Multiple types of high performance PDC cutters are strategically arranged on bit for improved service life of the bit.
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
Advantage: Higher nozzle counts and/or fixed ports to best serve cleaning, cooling and cuttings evacuation requirements with available hydraulic flows. Allows for higher flow rates with minimal increase in pump pressure.
Benefit: Optimized ROP and bit life; Longer drilling intervals without need for tripping
Increased footage drilled in abrasive applications
Feature: Diamond are impregnated in the matrix behind the PDC cutters
