🔧 Core Equipment Components

Rotary Table

Rotary Table

The rotary table is a critical component of the drilling rig, facilitating speed and torque output through spiral bevel gear pairs. It drives drilling tools with high precision and smoothness.

  • Meets API 7K and SY/T5531 requirements.
  • Spiral bevel gear for high load capacity and long service life.
  • Casting and welding structure for superior rigidity.
  • Reliable splash lubrication for gears and bearings.

Drawworks

The essential hoisting mechanism that spools the drilling line to raise or lower the drill stem and bit. Built for heavy-duty performance and high-frequency use.

  • Shafts made of high-strength alloy steel.
  • Pressure-lubricated high-accuracy chains.
  • Water-cooled brake rim with intermediate frequency quenching.
  • Main band or disc brake supplemented by auxiliary eddy current brakes.
Drawworks
Mud Pumps

F-Series Mud Pumps

Standardized API Spec 7K mud pumps featuring sturdy, compact structures suitable for high-pressure and large-displacement oil field requirements.

  • Interchangeable fluid end consumables.
  • Longer stroke operation for extended service life.
  • Advanced suction pulsation dampers.
  • Available Models: F-500, F-800, F-1000, F-1300, F-1600.

Rotary Drilling Hose

Designed for flexible connection between the drilling riser and the movable water faucet. Capable of handling water-based or oil-based mud under extreme pressures.

  • Resistant to H2S corrosion.
  • Reinforced with steel wire or carbon fiber sub-layers.
  • Maintains performance at high temperatures and aniline points.

Frequently Asked Questions

Q1: What is the main advantage of the Top Drive System (TDS)?

A: TDS allows for drilling with triples instead of singles, reducing connection time by two-thirds and significantly enhancing overall drilling efficiency and speed.

Q2: Are the mud pump spare parts compatible with other brands?

A: Yes, our F-series mud pump consumable parts are designed according to API Spec 7K standards, making them interchangeable with other compliant brands like EMSCO.

Q3: What certifications do the drilling components carry?

A: Our main equipment complies with API Spec 8C, API 7K, CNPC, and ISO 9001 quality management standards.

Q4: What is the maximum drilling depth for the DQ series TDS?

A: Depending on the specific model (DQ40, DQ50, or DQ70), the maximum hole depth ranges from 4,000 meters to 7,000 meters.

Q5: Can the rotary table handle high-load operations?

A: Yes, the rotary table uses a spiral bevel gear drive system which provides higher loading capacity, smooth running, and a longer service life.

Q6: Is the equipment suitable for harsh environments?

A: Absolutely. Our equipment features antiseptic and explosion-proof properties, and components like the drilling hose are resistant to hydrogen sulfide (H2S) corrosion.
