Choose the Right PDC Cutter, Drill Smarter & Faster

In oil drilling, the performance of PDC bits relies entirely on PDC cutters (Polycrystalline Diamond Compact), which directly determine drilling efficiency and bit life. The key to selecting the right PDC cutters is precise matching with formation characteristics: soft formations prioritize efficiency, hard formations prioritize durability, and complex formations prioritize adaptability. Improper selection accelerates cutter wear, increases bit consumption, slows down drilling progress significantly, and raises operational costs. 

Featuring formation-specific designat its core, DrillMore PDC bits perfectly solve selection and performance challenges across all drilling scenarios, making them the preferred choice for drillers worldwide. 

For soft formations(mudstone, unconsolidated sandstone) where high efficiency is critical, DrillMore uses large 16–19mm flat-faced cutters. Sintered from high-quality 5–10μm diamond powder under high temperature and high pressure, these cutters have sharp edges and low cutter density. Combined with CFD-optimized fluid courses, they achieve high penetration rates, efficient chip removal, and excellent anti-balling performance, fully meeting the demands of soft-formation drilling. 

For medium-hard formations (tight sandstone, limestone), DrillMore takes a balanced approach with 14.5–16mm standard cutters. Gradient-reinforced composite matrix material delivers wear resistance and impact resistance, with cutter density optimized through precise hydraulic simulation. This balances cutting efficiency and service life against mild abrasive formations, demonstrating outstanding stability and cost-effectiveness in fields such as the Jiyang Depression and Ordos Basin. 

For hard and highly abrasive formations (quartz sandstone, chert), DrillMore’s premium high-thermal-stability PDC bits are the optimal solution. Equipped with small 13–14.5mm shaped cutters (chisel, helmet-shaped), their fine-grain diamond layers offer wear resistance (relative wear ratio ≥ 120000) well above industry standards. High-density cutter layout and FEA-optimized stress distribution resist severe abrasion, high temperatures, and impact, preventing premature wear or chipping and greatly extending service life. 

For complex formations (hard interbeds, gravel layers, high H₂S environments), DrillMore’s special impact-resistant PDC bits are all-round performers. They adopt mixed cutter shapes and staggered layout of small and medium-sized cutters: flat cutters maintain efficiency, while shaped cutters withstand impact. Paired with corrosion-resistant nozzles and metal-rubber composite seals, they tolerate H₂S-bearing fluids. In complex applications such as high-sulfur subsalt reservoirs and coalbed methane horizontal wells in the Ordos Basin, they effectively prevent cutter breakage and sticking, ensuring safe and efficient drilling. 

There is no universal PDC cutter, but DrillMore PDC bits deliver **full formation adaptability**! 

From soft formations to complex high-sulfur environments, from vertical wells to horizontal wells, every model is precisely engineered for formation conditions. API-standard threads ensure efficient and stable torque transmission. Each bit achieves industry-leading footage and rate of penetration (ROP), with one-run drilling successes across numerous wells nationwide, greatly shortening drilling cycles and reducing operational costs.
