Product Introduction

Polycrystalline Diamond Compact (PDC) Drill Bits are state-of-the-art drilling tools designed for high-efficiency and cost-effective performance in a wide range of geological formations. At the core of our PDC bits are synthetic diamond composite cutters, which are sintered onto a tungsten carbide substrate under ultra-high temperature and pressure. 

Product Description & Key Features

Enttu's PDC bits are engineered for durability and precision. Each bit consists of a robust body (available in steel or matrix/milled formats) with multiple blades. The cutting structure is formed by precisely brazing numerous PDC cutters onto these blades.

• Advanced Cutter Technology: We utilize various cutter geometries, including planar, conical, chisel-shaped, and specialized axe-shaped cutters, to optimize performance for specific rock types, from soft shales to hard, abrasive formations.

• Optimized Hydraulics: The bit body features strategically designed fluid flow courses and nozzle placements. This ensures efficient cleaning of cuttings from the bit face, prevents balling, and enhances cooling of the cutters, which is critical for maintaining rate of penetration (ROP) and bit life.

• Robust Construction: Made from high-grade materials such as PDC cutters with 45CrMo steel bodies, our bits offer exceptional structural integrity. The PDC layer itself has seen technological advances, with thickness and thermal stability significantly improved to withstand downhole temperatures exceeding 1100°C.

• Standard & Custom API Connections: Our bits come with standard API threaded connections (e.g., 2 7/8 API Reg) for easy integration into your drill string and can be customized to meet specific requirements.

Key Advantages of Choosing YK Drill PDC Bits

Switching to Enttu Drill PDC Bits translates directly to lower cost-per-foot and enhanced operational efficiency. Our bits are proven to deliver:

• Substantially Higher Drilling Efficiency: Field applications demonstrate that PDC bits can achieve 57% to 69% higher drilling rates compared to conventional tungsten carbide bits in medium-hard rock formations.

• Exceptional Durability & Longevity: The extreme wear resistance of polycrystalline diamond results in significantly longer service life. In medium-hard strata, our specialized PDC bit designs have shown a service life more than 2 to 3 times that of conventional drill bits.

• Outstanding Economic Value: The combination of faster penetration and longer life drastically reduces total drilling costs. Studies indicate that PDC bits can lower drilling costs by over 60% compared to natural diamond bits and offer superior cost-efficiency versus roller cone bits in applicable formations.

• Proven Reliability in Key Applications: PDC bits are the dominant choice in modern oil and gas drilling, holding over 85% market share in certain key markets like China and the U.S.. They are exceptionally effective in directional drilling, especially in shale gas horizontal wells, and perform reliably in formations like soft to medium-hard clays and shales.

Product Classification & Selection Guide

ENttu Drill offers a comprehensive range of PDC bits to match your specific drilling challenge. They can be classified based on several key criteria:

1. By Body Material:

• Steel Body PDC Bits: Machined from high-strength alloy steel, these bits are generally more economical and offer excellent impact resistance. Ideal for a broad range of standard drilling applications.

• Matrix Body PDC Bits: The bit body is formed from tungsten carbide powder sintered in a furnace. These bits offer superior abrasion resistance and are the preferred choice for the most abrasive and hostile downhole environments.

2. By Cutter Type & Application:
The shape and technology of the PDC cutter are tailored for formation hardness and drilling mechanics.

• Standard Planar Cutters: For soft to medium-hard, non-abrasive formations.

• Specialty Shaped Cutters (Conical, Axe-shaped, etc.): Designed for enhanced durability and efficiency in hard and interbedded formations. These "non-planar" cutters improve rock fracturing and heat dissipation.

• Directional & Steering PDC Bits: Feature specialized blade and cutter layouts (e.g., asymmetric designs) to provide precise tool face control and better responsiveness for directional drilling applications.

3. By Application Area:
Our product line covers diverse industrial needs:

• Oil & Gas Drilling: The primary application, including vertical, directional, and horizontal wells for conventional and unconventional resources (shale gas/oil).

• Geothermal Drilling: Engineered to withstand the high-temperature environments of deep geothermal wells.

• Mining & Mineral Exploration: Used for coreless drilling in coal mining, methane drainage, dewatering, and exploration in hard rock formations.

• Water Well & Construction Drilling.

4. By Profile & Diameter:
We supply bits in various profiles (e.g., shallow cone, parabolic, flat) and a wide range of diameters to suit your hole size requirements
