Top quality Standard oil drilling rig ZJ70/4500DBS , Oil Drilling Equipment
Description:
• BOP and well/choke equipment and facilities shall be equipment with rig package according to client’s requirement.
• The mud pumps equipped with the rig are single action, triplex slurry pumps, electrically driven by AC or DC motors.
• The power drive system available in SCR (AC-SCR-DC) or VFD (Variable Frequency Drive, AC-DC-AC) System.
Specifications :
| J70/4500DBS | Cantilevel type substructure, whose rig floor can reach 10.5m , is more suitable for exploration and exploitation of HP gas well; driller's cabin is separated from drill floor, which can independently lifted to its position by hydraulic and avoid effect caused by drill floor vibration on instruments and control elements in it.
Cooperate with top drive, three sets of 1600 hp VF mud pump provide good conditions for inclined wells and directional wells drilling. | ||||||
