3. Function Description

3.1 Hoisting & Structural System Functions

The JJ315/44.8-K mast and DZ315/9-S substructure form the rig’s rigid support framework, bearing the full hook load and providing operational space for drilling tools. JC-50J drawworks drives wire rope lifting for drill string operation, while TC-315 crown block and YC-350 travelling assembly enable smooth hoisting of drilling tools. Deadline anchor JZG35-R secures the wire rope to maintain stable tension during lifting operations.

3.2 Rotating & Drilling Tool Functions

ZP-275 rotary table and SL-450 swivel drive drill string rotation for wellbore drilling, with FSK-15 Kelly spinner accelerating pipe connection. Master bushing FW-275 and roller bushing GF 5-1/4″ center the drill string, while drilling tools (overshot LT206, spear LM34) handle fishing and well workover operations. Bit gauges and casing drift ensure tool size compliance and casing integrity.

3.3 Well Control & Safety Functions

2FZ35-70 BOP and FKQ control system provide emergency well shutoff to prevent blowouts, with choke & kill manifold regulating well pressure. Inside BOP HY-62 acts as a secondary well control barrier, while gas detectors and smoke detectors monitor hazardous gases to ensure rig site safety. Escape chutes offer emergency evacuation routes for rig personnel.

3.4 Mud Circulation & Solid Control Functions

3NB-1300C mud pump drives mud circulation, with solid control equipment (degasser, desander, centrifuge) removing solids from drilling mud to improve mud quality and reduce drilling costs. Mud mixing hopper prepares mud to meet drilling requirements, ensuring stable mud performance throughout operation.

3.5 Power & Auxiliary Functions

Prime mover P12V190B and VOLVO generators supply primary and backup power, with energy-saving generators reducing power consumption. Auxiliary equipment (air winch, power tongs, welding machine) supports rig assembly, pipe handling, and on-site maintenance, streamlining drilling operations.

4. Structural Features

• High-Load Structural Design: Mast and substructure use box-section welded alloy steel with Q345B high-strength material, resisting bending and torsion under 315-ton maximum load, with a safety factor of 2.5 per API 4F standards.

• Wear-Resistant Transmission Parts: Drawworks gears and rotary table components use 42CrMo hardened steel, with HRC55-60 surface hardness to reduce tooth wear and extend service life.

• High-Pressure Well Control Sealing: BOP and manifold components use metal-to-metal sealing structures, withstanding 70MPa working pressure without leakage, complying with API 16A standards.

• Modular Integrated Design: All components are modular and pre-assembled, reducing on-site installation time by 30% and simplifying rig commissioning and maintenance.

• Corrosion-Resistant Coating: External structural parts adopt electrostatic spraying and hot-dip galvanizing, resisting salt spray, humidity, and abrasive dust for 5200 operating hours.

5. Applicable Operating Conditions

This ZJ50J 1500HP rig equipment package is engineered for diverse onshore drilling environments, complying with API and national safety standards:

• Load Parameters: Maximum hook load 315 tons, working pressure up to 70MPa, 1500HP continuous power output

• Temperature Range: -30°C (cold region rigs) to 110°C (desert drilling operations)

• Environmental Compliance: Plateau, desert, grassland, and cold-region onshore oilfields; dust, sand, rain, snow, and low-temperature conditions

• Application Scenarios: Onshore oil/gas drilling, well workover, directional drilling, and exploration drilling operations

6. Maintenance & Care Recommendations

6.1 Routine Maintenance Schedule

Inspect mast and substructure welds every 600 operating hours for cracks, and lubricate drawworks bearings and gears every 400 hours. Test BOP sealing performance every 800 hours, and calibrate gas detectors every 300 hours to ensure accuracy. Replace mud pump wearing parts every 1200 hours, and check generator fuel and lubrication systems every 500 hours. Inspect safety equipment (escape chute, detectors) monthly for functionality, and tighten all structural fasteners every 700 hours.

6.2 Engineer On-Site Tips & Pitfall Warnings

Never exceed the 315-ton hook load limit to avoid mast deformation, and use only specified lubricants for drawworks and rotary table components. Conduct BOP pressure testing before each well section drilling, and avoid using damaged drilling tools to prevent well accidents. Keep solid control equipment running continuously during drilling to reduce mud solids content, and store electronic safety detectors in dry, dust-free areas to extend service life. Do not modify rig components without technical approval, as this voids API certification and risks safety hazards.
