ZJ90 3000HP/5850kN 9000m Conventional Land Drilling Rig
Product model
The land drilling rig is used for oil and gas exploration and development on wells that are 6000- 7000m (drill pipe 4 1/2") or 5000-8000m (drill pipe 5") deep. Maximum drilling depth 9,000 m.
1. The basic structure, design, and manufacture specifications are according to international standards, including API, IEC,and HSE.
2. The rig driving model could be VFD, mechanical orcombined drive, client could require the rig model.
3. The rig substructure model could be box-on-box, swing-upor hydraulic cylinder raising, with compact structure.
4. Drilling rigs can choose DC drive, AC drive, mechanical drive drive and hybrid drive solutions, which can be configured according to customer needs.
5. All systems and equipment in this drilling rig adopt high-temperature resistant components and air cooling systems for greater effectiveness.
