Our directional drill bits offer exceptional performance across strata levels 1–12 thanks to their precisely built PDC 1308 cutters, three-blade configurations, and adaptable connection types. With a total investment of CNY 50 million and yearly sales of RMB 60 million, we offer dependable drilling solutions that the mining engineering and oil and gas exploration industries throughout the world rely on.

Understanding PDC Drill Bit Technology

Polycrystalline Diamond Compact Drill Bits represent a breakthrough in drilling efficiency. Unlike traditional roller cone bits, these fixed-cutter tools use synthetic diamond cutters bonded to tungsten carbide substrates. This design enables a shearing action that removes rock more effectively than crushing methods.

The result? Higher penetration rates and significantly extended bit life. Your drilling operations benefit from fewer bit trips and reduced downtime. The exceptional hardness of lab-grown diamond crystals ensures durability even in abrasive geological conditions.

Our bits adjust to a range of rock types, from medium-hard strata to soft sediments. Because of their adaptability, they are perfect for water well applications, mining engineering, geothermal drilling, and oil and gas exploration.

Technical Specifications

Core Advantages of Our PDC Drill Bits

Advanced Cutter Technology

Our Polycrystalline Diamond Compact Drill Bits incorporate high-performance PDC cutters that significantly prolong operational life. The synthetic diamond layer provides unmatched wear resistance while the tungsten carbide base absorbs shock during drilling operations.

Optimized Hydraulic Design

Computational fluid dynamics (CFD) hydraulic balance design ensures superior bit cleaning and efficient cutting removal. Multiple nozzle configurations optimize cooling and cuttings evacuation based on your available hydraulic flows.

Enhanced Penetration Performance

The evolute asymmetrical blade cutter design distributes bit load evenly, preventing bit whirl and maintaining stability. Composite gage protection combined with low torque design increases your rate of penetration across various formations.

Manufacturing Excellence

Every bit undergoes rigorous quality control in our modern Xi'an facility. Our team's participation in introducing China's first PDC manufacturing enterprise gives us unique technical insights that translate into superior product reliability.

Industry Applications

Oil & Gas Exploration

Your drilling teams need tools that perform consistently in challenging downhole conditions. Our bits deliver the penetration rates and durability required for directional drilling and horizontal wells.

Mining Operations

Coal mining and mineral exploration demand bits that can handle abrasive rock formations. The wear-resistant diamond cutters maintain cutting efficiency throughout extended drilling campaigns.

Geothermal Projects

Temperature-resistant matrix body designs withstand the extreme heat encountered in geothermal drilling. This allows for more continuous drilling with fewer interruptions for bit changes.

Water Well Drilling

Cost-effective drilling requires bits that balance initial investment with long-term performance. Our PDC Bits reduce your overall drilling costs through extended service life and improved efficiency.

Project Case Studies

Medium-Hard Formation Drilling Project

A coal mining operation required consistent performance across varying strata hardness. Our three-blade PDC directional drill bit with 1308 cutters maintained stable penetration rates throughout the project. The balanced blade design prevented bit whirl in directional sections while composite gage protection extended bit life by 40% compared to previous tools.

Directional Well Application

An oil exploration project needed reliable performance in strata levels 4-9 with complex directional requirements. Our customized connection type ensured compatibility with existing drill strings. The CFD-optimized hydraulic design provided excellent cuttings removal, enabling faster drilling cycles and reducing non-productive time.

Packaging and Transportation

We meticulously package products for safe transit. Sturdy wooden crates, foam inserts and secure wrapping prevent transportation damage, ensuring intact delivery and offering you peace of mind.

Transaction Feedback

We value customer feedback and continuously strive to improve our products and services. Your satisfaction is our success.

FAQ

Q1: What kind of formations are suitable for your drill bits?
A: Our bits cover mild to medium-hard formations and are designed for stratum levels 1–12. Coal seams, sedimentary rocks, and moderately abrasive formations can all benefit from the PDC 1308 cutter configuration's adaptability to various geological conditions.

Q2: What is the difference between PDC and conventional roller cone bits?
A: By shearing instead of crushing, PDC bits provide greater penetration rates. Longer bit life, fewer journeys, and lower operating expenses are all benefits. By removing moving elements, the fixed-head design lowers the chance of mechanical failure.

Q3: Is it possible to modify the type of connection for our drilling apparatus?
A: Definitely. To meet your unique drill string needs, we provide completely customizable connection types. To guarantee a smooth integration with your current equipment, our technical staff collaborates with you.

Q4: How long does it usually take you to deliver?
A: For purchases that satisfy our 10-piece minimum, standard delivery takes 5-7 business days. During the consultation process, our team will offer a comprehensive schedule for bespoke demands.

Q5: Do you offer post-purchase technical assistance?
A: Throughout the product lifecycle, our more than 20 senior specialists provide thorough technical assistance. Based on your unique drilling conditions, we help with bit selection, operational guidance, and performance optimization.

Q6: Which quality requirements are met by your bits?
A: In our 6,000-square-meter facility, we uphold strict quality control procedures as a high-tech company with independent intellectual property rights. Before being shipped, each bit is thoroughly inspected to guarantee reliable performance.
