ZJ70/4500LDB , High Efficiency Electrical Onshore Oil Drilling Rig


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.

• 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.

• A fully equipped mud circulation system including mud tanks, solids control equipment, mud conditioning equipment and circulation lines completed with the rig package.

• An analog and digital drilling parameter and data monitor and recording system available on the rig.

• BOP and well/choke equipment and facilities shall be equipment with rig package according to client’s requirement.

Specifications :


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.
RT and auto-bit-feeding both adopt all-digital auto control technique, which make the performance of the rig under drilling condition get close to digital-control electric VF rig; driller operates the touch screen to fulfill drilling operation through optimized drilling parameters, which will reduce labor intensity significantly and improve work efficiency. Display, restoration, regulation and control, remote management of major drilling parameters can be realized.
