ZJ70/4500LDB , High Efficiency Electrical Onshore Oil Drilling Rig
Description:
HYRD provides model ZJ70/4500LDB electrical onshore drilling rigs which are designed to drill and complete an oil and gas well with depth from 4000 m to 7000 m.
• The Rig components such as mast, substructure, traveling block, hook, swivel, rotary table, drawworks, etc, conform to API specifications and the industry standards.
• The mast fabricated in a pin connection type cantilever structure, monkey board, stabbing board and other mast auxiliaries equipped the mast assembly, its design is suitable to install top drive unit.
• The substructure can be manufactured in two-step raising and/or box-on-box substructure. And steps, handrails, BOP handling system and other appendixes equipment and facilities fully equipped with the substructure.
Specifications :
| ZJ70/4500LDB | On the basis of common mechanical rig, driving of RT and DW is separated, and RT is driven by an independent AC VF motor. RT rev, torque and mud pump stroke can be adjusted separately as per drilling technology, which provides precondition and guarantee for drilling technology optimization and auto-bit-feeding realization. | |||||
