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, 215.9mm PDC bits, drilling fluid end accessories, and electric/hydraulic control system parts, with unique model identifiers (0101-39M, JK00213-48, SFZ2835-17, 4962603, 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, wear-resistant polycrystalline diamond for PDC bits, 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 hinge pins, pressure rings, check valves, and ram assemblies provide zero-leak pressure containment up to 70MPa, preventing blowouts and ensuring compliance with well control safety regulations; O-rings and retaining rings maintain stable sealing in high-pressure and high-temperature environments.

• Drill Pipe Handling Stability: ZQ203-100/ZQ203-125 clamp pins, sleeves, and quick release valves enable secure, precise gripping of drill pipes; inner ring gears and brake discs ensure smooth clamp operation, reducing pipe damage and handling risks.

• Rig Power Transmission: ZJ series rig intermediate shafts, sprockets, connection plates, and brake components ensure smooth torque transfer for hoisting and rotation; oil seals and sealing rings prevent lubricant leakage, extending transmission component life.

• Drilling & Hydraulic System Efficiency: 215.9mm PDC bits deliver fast, efficient rock breaking in various formations; F-1300/F-1600 hydraulic tank filters, guide rails, and valves maintain clean fluid flow and stable system pressure; liquid end packing and plunger parts prevent fluid leakage in mud pump systems.

• Diesel Engine & Auxiliary Performance: 190 series/Detroit/Volvo diesel engine gaskets, oil seals, and filters optimize combustion, prevent fluid leaks, and extend engine service life; control console air treatment elements and sensors ensure stable operation of electric/hydraulic control systems.

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, V-shaped seals, and rubber packing adopt a double-layer labyrinth structure, effectively blocking dust, mud, and fluid leakage in harsh field environments.

• Modular Quick-Change Design: Wear-prone parts (PDC bit components, BOP seals, clamp accessories) use a modular structure, reducing repair time by 68% compared to traditional integrated parts.

• High-Wear Resistance Materials: PDC bits use premium polycrystalline diamond compacts with 98.5% hardness; metal components are coated with a high-density anti-corrosion layer, resisting saltwater, acidic drilling fluid, and extreme temperature damage.

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) / 0-1.6MPa (low-pressure valve systems)

• Temperature Range: -45°C to 245°C (sealing components) / -35°C to 210°C (mechanical structural parts & PDC bits)

• Environmental Types: Offshore saltwater platforms, arid desert drilling sites, cold-region oilfields, high-temperature deep well operations, hard rock drilling formations

• Application Scenarios: Routine rig maintenance, emergency fault repair, equipment refurbishment, well control operations, drill pipe/casing handling, high-speed rock drilling

5. Maintenance & Upkeep Recommendations

• Regular Inspection Cycle: Inspect BOP sealing components, drill pipe clamp wear parts, and rig shaft seals every 480 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 320 hours; replace hydraulic tank filters and diesel fuel filters every 1300 hours to prevent fluid contamination.

• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and PDC bit components in anti-oxidation packaging to prevent premature aging and damage.

• 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 PDC bit wear; adjust valves and replace worn components if pressure fluctuations or drilling efficiency drops occur.

On-Site Fault Repair Cases (Field-Verified Solutions)

Case 1: FZ35-70 BOP Hinge Positioning Pin Failure Repair

An offshore drilling platform experienced BOP gate misalignment due to a worn hinge positioning pin (JK00213-48), causing sealing failure and pressure testing rejection. Replacing the damaged pin with our precision-forged component realigned the BOP gate, restored sealing performance, and the BOP passed 70MPa pressure testing on the first attempt, resuming operations within 2 hours.

Case 2: ZQ203-100 Drill Pipe Clamp Pin Breakdown Fix

A land drilling rig in the Middle East suffered drill pipe slippage due to a broken clamp pin (0101-39M) on the ZQ203-100 clamp, halting drilling operations. Installing our high-strength alloy steel pin restored clamping force, eliminated slippage, and the clamp operated flawlessly for 8+ months of continuous use with no further issues.

Case 3: ZJ45 Rig Intermediate Shaft Oil Seal Leak Resolution

A ZJ45 drilling rig had severe lubricant leakage from the intermediate shaft, leading to accelerated sprocket wear and reduced transmission efficiency. The root cause was a degraded oil-resistant rubber seal (106.02.20.41). Replacing the seal with our high-temperature resistant variant stopped leakage, restored proper lubrication, and extended shaft service life by 45%.
