🚀 Key Components

Rotary Table

The rotary table is an essential part of the drilling rig. Its function is to slow down a pair of bevel gear pairs during drilling operations, providing speed and torque output to drive drilling tools.

Meets API 7K requirements.
Spiral bevel gear drive for higher loading capacity and smooth running.
Casting and welding structure for superior rigidity.
Splash lubrication for gears and bearings.

Drawworks

The primary hoisting mechanism on a drilling rig. It acts as a large winch that spools the drilling line to raise or lower the drill stem and bit.

Alloy steel shafts and high-strength pressure-lubricated chains.
Drum equipped with spiral grooves and ventilating air clutches.
Water-cooled brake rim with intermediate frequency quenching.
Main band/disc brake plus auxiliary eddy current brake.

Top Drive System (TDS)

TDS is one of the greatest technological revolutions in petroleum equipment, replacing the Kelly and rotary table. It allows for drilling with triples instead of singles, reducing makeup/breakout work by two-thirds.

Standard: API SPEC 8C

Mud Pumps (F Series & 3NB Series)

API Spec 7K standard products with interchangeable fluid end parts. Designed for high pump pressure and large displacement requirements.

Sturdy, compact structure with reliable performance.
Longer stroke for lower-speed operation, extending consumable life.
Advanced suction pulsation damper for optimal performance.
Models available: F-500 to F-1600 and 3NB350 to 3NB1600A.

Rotary Drilling Hose

Flexible connection for high-pressure mud delivery. Resists corrosion from hydrogen sulfide and handles water-based or oil-based muds.

Reinforced with steel wire or steel link lines.
Carbon fiber outer sub and stainless steel armor options.
Min. aniline point at 66ºC.

❓ Frequently Asked Questions

What is the maximum drilling depth for these systems?

The system is available in various models (DQ40BS, DQ50BS, DQ70BS) capable of reaching depths of 4000m, 5000m, and up to 7000m respectively.

Which industry standards do the products comply with?

All equipment is fully compliant with API Spec 8C, API Spec 7K, CNPC standards, and ISO 9001 quality management certifications.

What are the primary safety features of the Top Drive System?

The system includes an emergency stop, torque limiting, anti-collision technology, and a comprehensive fault self-diagnosis system for safe operations.

Can the mud pump parts be easily replaced?

Yes, the F series mud pumps are designed so that consumable parts at the fluid end are interchangeable with standard parts that comply with API specifications.

What drive technology is used in the Top Drive?

The system utilizes an AC variable frequency electric drive, controlled via a digital HMI and PLC system with remote diagnostic capabilities.
