The ZJ40 Skid-mounted Drilling Rig Series is a land rig with a maximum drilling depth capacity of 4000 meters. It is primarily used for oil and natural gas exploration and development at well depths of 2500–4000m (using 4-1/2” drill pipes) or 2000–3200m (using 5” drill pipes). The rig’s core parameters, structural forms, and design comply with international norms such as API, IEC, and HSE.
Key features include:
Use of high-temperature-resistant components and air cooling systems, making it suitable for high-temperature, desert, and rainy environments.
Designed and configured using advanced international standards and equipment selection.
