Products Description
Application

ZJ30 skid-mounted drilling rig is suitable for drilling wells in the depth lower than 3000m. It can work in different sort of environments like shallow sea areas, beaches, desert and cold areas.

Features
  • Modular Skid-Mounted: The drilling rig adopts a highly modular design, dividing the equipment into multiple skids such as the main skid, pump set, and base, allowing for quick installation, disassembly, and convenient relocation.
  • Multiple Drive Types: Depending on different needs, the ZJ30 drilling rig mainly offers two drive types: mechanical drive (diesel engine + hydraulic coupling/torque converter + chain-driven parallel gearbox) and electric drive (AC variable frequency motor). The AC variable frequency electric drive drilling rig offers higher automation, better speed regulation, and can achieve automatic drilling with constant drilling pressure.
  • Derrick and Base: The derrick typically adopts a K-type (front-opening) structure, low-position installation, and integral lifting and lowering, ensuring high safety. The drilling platform base comes in various forms, including box-type and rotary-lift type, providing a spacious and flat drilling surface.
  • Braking System: The main brake can be equipped with a hydraulic disc brake, enabling remote operation, greatly improving the driller’s working conditions, and providing a foundation for automated drilling; the auxiliary brakes mostly use electromagnetic eddy current brakes or pneumatically controlled water-cooled disc brakes to ensure safety during heavy-load drilling.
  • Fully equipped: It can be equipped with complete solids control systems, well control systems, high-pressure manifolds, power generation rooms and other supporting facilities to meet the drilling process requirements of different customers.
