Refurbished ZJ30 Drilling Rig Oilfield Equipment

ZJ30 Drilling Rig – Product Introduction

The ZJ30 is a 3000-meter-class land drilling rig designed for medium-depth vertical and directional wells. It is widely used in oil and gas exploration, workover operations, and shallow-to-medium resource development.

Key Features

• Proven Drive Options: 

• Available in mechanical (chain or V-belt compound), AC electric VFD, or DC drive configurations to suit different power supply conditions and operational preferences.

• Compact & Mobile Design: 

• The rig is available in skid-mounted, truck-mounted, or trailer-mounted variants. The mast and substructure are designed for quick rig-up and rig-down, reducing moving time between wells.

• Reliable Hoisting & Braking: 

• Equipped with a 750 HP drawworks as standard, with hydraulic disc brake as the main brake and auxiliary braking options including electromagnetic eddy current or pneumatic systems.

• Flexible Rotary Drive: 

• The rotary table can be independently driven by an AC or DC motor in electric rig configurations, enabling stepless speed regulation and better control for directional drilling.

Technical Specifications (Typical)

• Nominal Drilling Depth: 1,600–3,000 m (with 114 mm / 4½" drill pipe)

• Max. Static Hook Load: 1,800 kN (approx. 400,000 lbs)

• Drawworks Rated Power: 560 kW (750 HP)

• Mast Height: 41 m (135 ft) typical, with options for 36–43 m depending on configuration

• Substructure Height: 6 m (20 ft) typical, with 7.5 m options available

• Rotary Table Opening: 520.7 mm (20½") or 698.5 mm (27½")

• Mud Pump Power: Typically 2 × 735 kW (1000 HP) or 2 × 956 kW (1300 HP)

Application
Suited for development drilling in medium-depth fields, workover operations, and regions where rapid rig moves and moderate depth capacity are required.
