Product Description: 500MM API 7 5/8 REG 6 Wings PDC Matrix Bit for Oil and Gas

The 500MM API 7 5/8 REG 6 Wings PDC Matrix Bit is a high-performance, durable drilling tool designed for efficient penetration in soft formations commonly encountered in oil and gas well drilling. Built for reliability and long service life, this bit integrates advanced materials and precision engineering to optimize drilling performance, even in challenging downhole conditions.

High-Quality Construction

This PDC bit features a steel body that ensures superior durability and resilience during demanding drilling operations. The matrix body construction provides enhanced resistance to abrasion, impact, and heat, making it well-suited for extended drilling cycles. The use of premium-grade PDC cutters (size 1913) guarantees effective cutting action, while maintaining structural integrity across a wide range of operating environments.

Design and Configuration

With a diameter of 500MM, the bit is ideal for large borehole applications, particularly where hole stability is essential. It is equipped with six blades, each designed for optimized cutting efficiency, reduced vibration, and improved tool face stability. The six nozzles are strategically placed to ensure optimal fluid flow for cooling and cleaning, minimizing the risk of cutter damage and bit balling.

The bit’s 7 5/8″ API Regular pin connection ensures compatibility with standard drill strings, promoting ease of use and seamless integration into existing drilling setups.

Operating Parameters

The 500MM PDC matrix bit operates effectively within a rotational speed (RPM) range of 60 to 260 rotations per minute. This flexibility allows it to adapt to various drilling conditions and optimize rate of penetration (ROP) based on site-specific requirements. The recommended weight on bit (WOB) ranges from 30 to 120 KN/mm, with a maximum WOB limit of 150 KN, ensuring sufficient force for deep cutting while preserving cutter life.

The bit supports a flow rate between 26 to 56 liters per second (lps), delivering efficient cooling and debris removal during the drilling process. This contributes to smoother operation, reduced wear on the bit, and lower risk of overheating or clogging.

Formation Suitability

This PDC bit is specifically engineered for soft formations with sticky layers and low compressive strength. Typical formations include clay, marl, lignite, shale, and sandstone. These conditions often lead to bit balling or premature wear if the correct bit is not used; however, the 500MM PDC matrix bit is optimized to handle such challenges with ease. Its design reduces sticking and allows for consistent, smooth drilling even in sticky or swelling formations.

Applications

Ideal for a variety of drilling operations in oil, gas, water, and geothermal wells, this bit is widely used across both onshore and offshore environments. Its rugged design and superior performance make it suitable for exploratory and production wells alike, especially where reliability and reduced downtime are critical to operational success.

Summary

The 500MM API 7 5/8 REG 6 Wings PDC Matrix Bit is a top-tier drilling solution for soft formations. With its robust build, efficient cutter design, and compatibility with standard equipment, it delivers high ROP, extended service life, and consistent performance. Whether you’re drilling through shale, clay, or sandstone, this bit provides the strength and precision needed to get the job done efficiently and safely.
