Top quality Standard oil drilling rig ZJ70/4500DBS , Oil Drilling Equipment

Description:

HYRD provides model ZJ70/4500DBS 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.

• The main rig power system are diesel engine driven AC generators with enough power for operating the rig.

• The power drive system available in SCR (AC-SCR-DC) or VFD (Variable Frequency Drive, AC-DC-AC) System.

• The drawworks electrically driven by heavy duty DC or AC motors, with working speed continuously adjustable. Disc brake introduced as the main drum brake equipped with the drawworks unit.

• The mud pumps equipped with the rig are single action, triplex slurry pumps, electrically driven by AC or DC motors.

• Rotary table independently driven by a drive system consisting of truck motor.

• Air system equipped with the rig, consisting of two each screw rod type air compressor, air tanks and valves.

Specifications :

J70/4500DBS

It adopts integrated design of mechanical, electrical, hydraulic, pneumatic and digital control, utilizes fully the advantages of advanced digital control AC VF electric transmission, and simplifies its mechanical structure.

As adopting of slingshot type substructure, drill floor equipments and driller cabin etc realize low-position installation and integer lifting.

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.

Electric transmission adopts vector VF drive system to realize all digital operation and control, and also processes elementary functions of automation, intelligence and information to realize collection (signal), display, restoration, printing, remote monitoring and management of control and drilling parameters.
Wide-range, high-precision and effective control on bit pressure, bit rev, pump pressure and pump displacement can be easily achieved to improve drilling technology greatly.
By the use of VF technology, DW realizes max torque output when i ts speed is zero to ensure the suspension function of rig lifting system, which change traditional driller operation mode completely.
Operation and control system adopt dual-way PLC redundant design to improve the reliability of the system.
This rig is equipped with an integral driller's cabin, in which a driller can finish major operations.
