Products Description
Application

Including models of ZJ50/3150D and ZJ50/3150L, our ZJ50 series skid-mounted drilling rigs can be used to drill wells with the depth not exceeding 5000m. Based on the practical need of customers, they can work in shallow sea areas, beaches, deserts cold areas, etc.

ZJ50/3150D Skid-Mounted Drilling Rig Features
  • Speeds of the drawworks, rotary table and the mud pump can be steplessly regulated independently. This helps optimizes the drilling technology.
  • The derrick, substructure and drilling floor equipment can be assembled together in a low position and then integrally hoisted with the power of drawworks.
  • Full-digital automatic control technology is adopted to achieve automatic drill bit feeding.
  • This ZJ50/3150D skid-mounted drilling rig is equipped with a touch screen used to display, save, control and manage the drilling parameters. With the touch screen, the driller can easily control this drilling machine to keep it working in an optimal state. The touch screen also helps decrease the driller’s labor strength as well as enhance his working efficiency.

ZJ50/3150 Skid-Mounted Drilling Rig Features
  • Independent Drive Units: Unlike traditional drilling rigs where all components share a single power source, this rig features independent drive units for its rotary table, mud pump, and winch. This design enables more precise control and higher efficiency.
  • AC Variable Frequency Motors: The rotary table is driven by an AC variable frequency motor, allowing for precise control of speed and torque. Operators can independently adjust these parameters according to specific drilling needs.
  • Independent Speed ​​and Stroke Adjustment: The speed and stroke of both the mud pump and rotary table are independently adjustable, ensuring the rig can adapt to different operating conditions and enhancing its versatility.
  • Fully Digital Automatic Control: Rotary table speed adjustment and winch automatic feed functions are both achieved through a fully digital automatic control system. This represents an advanced technological solution for smooth and efficient drilling operations.
  • Performance Comparable to CNC Drilling Rigs: This skid-mounted drilling rig utilizes variable frequency motor technology, offering performance comparable to more advanced CNC drilling rigs, providing precise and reliable drilling operations.
  • Touchscreen Control: Operators can control the rig via a touchscreen, monitoring and adjusting operating parameters in real time. This not only simplifies operations but also reduces the physical exertion on drillers.
  • Remote management and data storage: The touchscreen not only allows for parameter adjustments but also displays, saves, and remotely manages drilling parameters. This provides greater flexibility and enables real-time optimization of operations.
