Introduction

 

PDC drill bit is mainly used to drill Oil well, gas well, water well, etc.We design and produce specifie PDC bit with good performance for each soft, medium and hard formation. Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance. Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life. The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth.

Design for higher ROP in drilling deeper and harder formations, PDC drill bit always drills from ground to bottom directly with less or even a single run, saving large amount of drill time and cost .

Differ from tricone bit, PDC drill bit runs with lower WOB but Higher RPM, so it usually works with downhole motor to pick up rotating speed.

The performance of PDC drill bit depends a lot on PDC cutters, we provide unique solution to specific requirement on varied formations.

Application

Suitable for medium hard formations with high compressive strength and abrasive properties. Limestone, hard gypsum, dolomite, sandstone, etc.

Features

 

Hydraulics: The movement and cooling of cuttings can be optimized by the hydraulic design that matches the chip quantity and displacement of each blade.

Durasef Gauge: Super strong material promotes gauge wear resistance to enhance long lifetime

Special Backrake Design: A Backrake can be added in the bit in order to prevent the bit from getting stuck when drilling.

5 Bullet Points

1.High Quality PDC Cutters

We adopted high-performance polycrystalline diamond compact (PDC) cutters with high hardness, abrasion resistance and thermal stability, ensuring fast drilling speed and long service life.  08, 09, 10, 13, 16, 19 and other general specifications, and various customized specifications of PDC cutters all available for the PDC bits.

 2.5-Wing Stable Structure

5-wing reinforced matrix/steel body design reduces vibration and ensures straight boreholes. Excellent hole stability and low deviation rate for long well sections.

·3. Optimized Hydraulic & Flushing System

Large flow channels and anti-clogging flute design improve cuttings removal efficiency and prevent bit balling in clay and sticky formations.

· 4.API Standard Thread Connection

Standard API REG/IF thread ensures perfect compatibility with most water well drilling rigs and drill pipes, easy installation and reliable connection.

5. Wide Application for Water Wells

Ideal for soft to medium formations such as sandstone, shale, clay, marl and loose gravel. Widely used in water well drilling, irrigation wells and geothermal boreholes.

The Characteristics of PDC Steel Body Bits

 PDC steel body drill bit (polycrystalline diamond composite drill bit) has become one of the core tools for modern efficient drilling due to its unique design and advanced materials. It uses high-strength alloy steel as the substrate and is embedded with high-density polycrystalline diamond composite (PDC) as the cutting unit, which combines sharpness, wear resistance, and impact resistance, and is suitable for the efficient rock breaking needs of extremely soft to extremely hard formations.
By scientifically arranging teeth, optimizing blade profiles, and designing hydraulic structures, rapid cutting and crushing of rock layers can be achieved, significantly improving mechanical drilling speed and single pass feed life. The steel structure has strong stability and excellent fatigue resistance, which can effectively suppress downhole vibration and displacement, ensuring precise and controllable drilling trajectory.
At the same time, the integration of high-quality PDC cutters and precision manufacturing processes enables them to maintain stable performance in high-temperature and high abrasive formations, significantly reducing the cost of frequent drilling and replacement, and achieving comprehensive economic benefits far beyond traditional roller drill bits.
With the ultimate pursuit of technical details,Haosus PDC steel body drill bits have been used in multiple deep oil and gas field projects at home and abroad, winning wide recognition from industry customers with lower comprehensive costs and higher drilling profits.
