Detailed Product Description & Technical Parameters
1. Product Introduction
This comprehensive spare parts collection covers BOP critical components, drill pipe clamp/power tong accessories, ZJ series rig shaft & brake parts, hydraulic tank components, diesel engine parts, drilling fluid additives, and electric/hydraulic control system accessories, with unique model identifiers (19.200-09, JK212-40S-5-1, RS11148.41.02, 3803471, etc.) for quick identification and targeted procurement. Raw materials are selected for extreme oilfield conditions: forged alloy steel for load-bearing parts, high-temperature fluororubber for seals, heat-resistant composites for engine components, and corrosion-resistant metals for hydraulic tank parts. Each part undergoes strict pressure testing, dimensional inspection, and wear testing before shipment, guaranteeing consistent performance and reliability.
2. Core Function Description
• BOP Well Control & Sealing: 35×35/35×70 BOP gate assemblies, rubber cores, and O-rings provide zero-leak pressure containment up to 105MPa, preventing blowouts and ensuring compliance with well control safety regulations; gate shafts and sealing components maintain stable operation during routine and emergency well control.
• Drill Pipe Handling Stability: ZQ203-100/ZQ203-125 clamp glands, planetary gearboxes, and cylinder covers enable secure, precise gripping of drill pipes; reversing valves and reset plates ensure smooth clamp operation, reducing pipe damage and handling risks.
• Rig Power Transmission: ZJ series rig intermediate shafts, sprockets, oil throwers, and brake components ensure smooth torque transfer for hoisting and rotation; rope stoppers and shaft sleeves prevent wear and oil leakage, extending transmission component life.
• Diesel Engine & Hydraulic System Efficiency: 190 series diesel engine pistons, injectors, and hoses optimize combustion and prevent fluid leaks; F-1300/F-1600 hydraulic tank bearings, flanges, and locks maintain clean fluid flow and stable system pressure.
• Drilling Fluid & Auxiliary Performance: PMHA-Ⅱ zwitterionic polymer coating agents and JX-ZQ polysaccharide viscosifiers enhance drilling fluid lubricity and stability; logging tools and flow meters support accurate well data monitoring and process control.
3. Structural & Material Features
• Ultra-Precision Machining: All structural parts feature CNC machining with ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation.
• Reinforced Sealing Design: Lip seals, skeleton oil seals, and rubber cores adopt a double-layer labyrinth structure, effectively blocking dust, mud, and fluid leakage in harsh field environments.
• Modular Quick-Change Design: Wear-prone parts (gate assemblies, brake components, filter elements) use a modular structure, reducing repair time by 65% compared to traditional integrated parts.
• Anti-Wear & Anti-Corrosion Coatings: Metal components are coated with a high-density anti-corrosion layer, resisting saltwater, acidic drilling fluid, and extreme temperature damage; friction surfaces have a 0.06mm wear-resistant layer, reducing friction coefficient by 60%.
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: 0-105MPa (BOP & high-pressure hydraulic systems) / 0-40MPa (routine rig systems)
• Temperature Range: -45°C to 240°C (sealing components) / -35°C to 200°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, drill pipe clamp wear parts, and rig shaft seals every 450 operating hours; check for cracks, wear, or leakage, and replace damaged parts immediately to avoid safety incidents.
• Lubrication Protocol: Lubricate rig sprockets, shafts, and clutch components with high-temperature lithium grease every 300 hours; replace hydraulic tank filters and diesel fuel filters every 1200 hours to prevent fluid contamination.
• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and gaskets in anti-oxidation packaging to prevent premature aging and hardening.
• 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, diesel engine temperature, and drilling fluid viscosity; adjust valves and replace worn components if fluctuations or abnormalities occur.

On-Site Fault Repair Cases (Field-Verified Solutions)
Case 1: ZQ203-125 Drill Pipe Clamp Gland Failure Repair
A land drilling rig in the Permian Basin experienced unstable drill pipe gripping due to a damaged right with ear gland (19.200-09) on the ZQ203-125 clamp, causing pipe slippage. Replacing the worn gland with our OEM-grade component restored clamping force, eliminated slippage, and resumed safe pipe handling within 1.5 hours, with no recurring issues in 7+ months of use.
Case 2: 35×35 BOP Gate Seal Leak Troubleshooting
An offshore drilling platform failed BOP pressure testing due to a worn 4-1/2″ gate seal rubber core (DFZ1310.01B-01-00) on the FZ35-35 BOP. Installing our high-temperature resistant rubber core resolved the leakage, and the BOP passed 70MPa pressure testing on the first attempt, restoring well control compliance and avoiding costly operational delays.
Case 3: ZJ45 Rig Intermediate Shaft Oil Leak Fix
A ZJ45 drilling rig suffered severe oil leakage from the intermediate shaft, leading to lubricant loss and accelerated sprocket wear. The root cause was a faulty oil slinger (106.02.20.48) and damaged skeleton oil seal. Replacing these two components eliminated oil leakage, restored proper lubrication, and extended shaft and sprocket service life by 40%.
Frequently Asked Questions (FAQ)
Question | Answer |
Are these BOP parts compatible with both 35×35 and 35×70 BOP models? | Yes, our BOP components are model-specific engineered: 35×35 parts fit FZ35-35/FZ35*35SK BOPs, and 35×70 parts fit FZ35-70/FH35-70 BOPs, with full API 16A compliance for sealing and pressure resistance. |
What is the service life of rubber seals and drill pipe clamp components? | Rubber seals last 15-21 months in normal conditions and 11-14 months in extreme high-temperature environments; drill pipe clamp components have a service life of 2500+ operating hours, far longer than standard aftermarket parts. |
Can these parts be used for both routine maintenance and emergency repairs? | Absolutely, all parts are designed for dual use: they perform reliably for scheduled maintenance and feature quick-install modular design for emergency repairs, minimizing rig downtime and operational losses. |
