Detailed Product Description & Technical Parameters
1. Product Introduction
This comprehensive spare parts collection covers 35×35 BOP cylinder heads, positioning pins, sealing rings and repair kits, ZQ203-100/ZQ203-125 clamp rollers, lifting cylinders and jaw plates, ZJ series rig shafts, clutches, sprockets and brake components, NK400E/NK500E/ND1250 chassis bearings, steel plates and steering parts, diesel engine filters, gaskets and injectors, top drive rollers and potentiometers, hydraulic tank valves and pullers, and drilling fluid additives, with unique model identifiers (JK00309-2R, RJ11148.06, 0101-11M, etc.) for quick identification and targeted procurement. Raw materials are selected for extreme oilfield resilience: forged alloy steel for load-bearing parts, high-temperature fluororubber for seals, hardened steel for wear components, and corrosion-resistant metals for hydraulic and BOP parts. Each part undergoes strict pressure testing, dimensional inspection and wear testing before shipment to guarantee consistent performance and reliability.
2. Core Function Description
• BOP Well Control & Sealing: 35×35 BOP cylinder heads, positioning pins and sealing rings provide zero-leak pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; repair kits and adapter rings extend BOP service life and ensure compatibility across models.
• Drill Pipe Handling Stability: ZQ203 clamp rollers, lifting cylinders and jaw plates enable secure, precise gripping of drill pipes; dust covers and gland components protect internal parts from dust and mud damage, reducing clamp wear.
• Rig Power Transmission & Braking: ZJ series rig shafts, clutches and sprockets ensure smooth torque transfer for winch and turntable operation; brake blocks, water air hoist packing and couplings deliver reliable, precise braking control to avoid operational accidents.
• Chassis & Power System Efficiency: NK/ND chassis bearings, steel plates and steering components ensure stable rig mobility; diesel engine filters, gaskets and injectors optimize combustion, prevent fluid leaks and extend engine service life.
• Hydraulic & Control System Performance: F-series hydraulic tank valves, pullers and piston rods maintain stable fluid flow and pressure; control console transmitters and valves ensure stable operation of rig electric and hydraulic systems.
3. Structural & Material Features
• Ultra-Precision CNC Machining: All structural parts feature ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation.
• Reinforced Multi-Layer Sealing: BOP sealing rings and engine gaskets adopt a labyrinth design, effectively blocking dust, mud and high-pressure fluid leakage in harsh field environments.
• High-Strength Wear Resistance: Load-bearing components use hardened alloy steel (59-65 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at extreme temperatures.
• Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp rollers, brake blocks) use a modular structure, reducing on-site repair time by 78% compared to traditional integrated parts.
4. Applicable Operating Conditions
These spare parts are engineered for onshore deep well drilling, offshore platform workover, desert oilfield operations, high-pressure well control and rig emergency maintenance, with full adaptability to the following conditions:
• Pressure Range: 0-70MPa (BOP & high-pressure hydraulic systems) / 0-35MPa (rig winch & brake systems)
• Temperature Range: -45°C to 265°C (sealing components) / -35°C to 230°C (mechanical structural parts)
• Environmental Types: Offshore saltwater platforms, arid desert drilling sites, cold-region oilfields, high-temperature deep well operations
• Application Scenarios: Routine rig maintenance, emergency fault repair, equipment refurbishment, well control operations, drill pipe/casing handling
5. Maintenance & Upkeep Recommendations
• Regular Inspection Cycle: Inspect BOP sealing components, clamp wear parts and rig shafts every 580 operating hours; check for wear, cracks or leakage, and replace damaged parts immediately to avoid safety hazards.
• Lubrication Protocol: Lubricate rig sprockets, shafts and clutch components with high-temperature lithium grease every 400 hours; replace hydraulic tank filters and diesel filters every 1700 hours to prevent fluid contamination.
• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and precision components in anti-oxidation packaging to prevent premature aging.
• Installation Standards: Follow API rig maintenance specifications for torque tightening (BOP bolts, engine fasteners); use specialized tools for seal installation to avoid damage and ensure proper seating.
• Performance Monitoring: Track hydraulic system pressure, engine temperature and rig operation; adjust valves and replace worn components if fluctuations or abnormalities occur.

On-Site Fault Repair Cases (Field-Verified Solutions)
Case 1: FZ35-35 BOP Positioning Pin Failure Repair
An onshore drilling rig in the North Sea region experienced BOP gate misalignment and sealing failure due to a worn positioning pin (RJ11148.06) on the FZ35-35 BOP, failing pressure testing and halting operations. Replacing the damaged pin with our precision-forged alloy steel component realigned the BOP gate, restored full sealing performance, and the BOP passed 70MPa pressure testing on the first attempt, resuming drilling within 1.5 hours.
Case 2: ZQ203-100 Clamp Roller Wear Fix
A desert drilling team reported frequent drill pipe jamming due to worn rollers (0101-11M) on the ZQ203-100 clamp, causing operational delays and pipe surface damage. Installing our hardened steel rollers restored smooth pipe movement, eliminated jamming, and extended roller service life by 75% compared to standard aftermarket parts.
Case 3: ZJ45 Rig Clutch Cover Breakdown Resolution
A ZJ45 drilling rig suffered complete power transmission failure due to a cracked upper stage transmission clutch cover (024.21.20.00 φ600), halting hoisting operations. Replacing the faulty cover with our OEM-matched component restored torque transfer, fixed power delivery issues, and the rig operated flawlessly for 11+ months of continuous use with no recurring problems.
