Introduction to Drag Bit 
YUXIANG PDC Drag Bit - Product Introduction
1. Product Overview
The YUXIANG PDC Drag Bit is a high-efficiency fixed-cutter drilling tool designed for soft-to-medium hard formations. As a core product of YUXIANG, it replaces the roller cone bit's crushing mechanism with continuous shearing force from strategically arranged Polycrystalline Diamond Compact (PDC) cutters, achieving faster drilling speeds, smoother operation, and lower overall costs. It is widely recognized as the optimal choice for applications prioritizing drilling efficiency, stability, and cost control.
2. Core Structural & Design Features
2.1 High-Strength Blade Structure
Adopts 3/4/5-wing integrated high-grade alloy steel design, ensuring exceptional impact resistance and fatigue durability. The robust one-piece structure eliminates weak points, making it suitable for high WOB (Weight on Bit) and high RPM drilling conditions.
2.2 Premium PDC Cutter Configuration
Equipped with high-grade PDC cutters (typically 13mm/16mm/19mm) arranged at optimal angles. This design maximizes cutting efficiency while maintaining excellent wear resistance, significantly outperforming traditional carbide bits in soft formations.
2.3 Optimized Hydraulic System
Features large-diameter water eyes and refined flow channels. The optimized drilling fluid circulation path efficiently cools the cutters, cleans the bottom hole, and carries rock cuttings, preventing mud balling and ensuring stable drilling performance.
2.4 Standard API Connection
Boasts premium API standard threads (e.g., 2 3/8", 2 7/8", 3 1/2" API REG), ensuring seamless compatibility with various drilling rigs and drill strings. The high-strength connection structure guarantees reliable operation under extreme loads.
3. Core Advantages
✅
Ultra-High Drilling EfficiencyDirect shearing cutting action delivers a much higher Rate of Penetration (ROP) than roller cone bits in soft formations, drastically shortening project cycles.
✅
Zero Moving Parts, High ReliabilityThe simple and robust structure minimizes mechanical failure risks, reducing trip frequency and maintenance costs significantly.
✅
Superior Formation AdaptabilityIdeal for clay, mudstone, shale, soft sandstone, and other soft-to-medium non-abrasive formations. Customizable blade counts and cutter layouts cater to diverse engineering needs (e.g., HDD, water wells, oil & gas surface sections).
✅
Cost-Effective PerformanceOffers longer service life and lower comprehensive drilling costs compared to conventional bits, providing excellent value for money.
4. Typical Application Scenarios
Oil & Gas Drilling: Preferred for top-hole sections and soft formation drilling in vertical and directional wells.
Horizontal Directional Drilling (HDD): Efficient for municipal pipeline, utility, and river crossing projects in soil and soft rock strata.
Water & Geothermal Wells: Enables fast drilling of shallow-to-medium depth wells in clay, sandstone, and limestone formations.
Mining & Geotechnical Engineering: Applied to blast hole drilling and geological exploration in soft rock strata.
