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 transmission/brake parts, hydraulic tank components, diesel engine parts, 215.9mm PDC bits, mud pump liquid/power end accessories, and electric/hydraulic control system parts, with unique model identifiers (JK00309-26, RJ11172.08, FX56S, 3028293, 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 and nitrile rubber for seals, premium polycrystalline diamond compacts for PDC bits, and corrosion-resistant metals for hydraulic tank and BOP components. 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 positioning pins, hydraulic cylinders, pressure rings, and sealing rings provide zero-leak pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; flanges and screw plugs secure hydraulic connections and block fluid leakage.

• Drill Pipe Handling Stability: ZQ203-100/ZQ203-125 clamp jaw plates, connectors, and planetary gearboxes enable secure, precise gripping of drill pipes; hydraulic motors and adapter parts ensure smooth tong operation, reducing pipe damage and handling hazards.

• Rig Power Transmission & Braking: ZJ series rig transmission shafts, sprockets, connecting plates, and brake blocks ensure smooth torque transfer for hoisting and rotation; disc brakes and pressure reducing valves deliver precise, reliable braking control for safe rig operation.

• Hydraulic & Mud Pump Efficiency: F-1300/F-1600 hydraulic tank valves, filters, and cylinder assemblies maintain clean fluid flow and stable system pressure; mud pump crossheads, valve bodies, and packing parts prevent fluid leakage and optimize pumping efficiency.

• Diesel Engine & Auxiliary Performance: Weichai/Detroit/Volvo diesel engine oil seals, valve assemblies, and filters optimize combustion, prevent fluid leaks, and extend engine service life; control console valves and air treatment components ensure stable operation of 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: U-shaped seals, packing sets, and oil seals adopt a double-layer labyrinth structure, effectively blocking dust, mud, and high-pressure fluid leakage in harsh field environments.

• Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp jaw plates, mud pump packing) use a modular structure, reducing on-site repair time by 70% compared to traditional integrated parts.

• High-Wear Resistance & Anti-Corrosion: Metal components are coated with a high-density anti-corrosion layer, resisting saltwater, acidic drilling fluid, and extreme temperature damage; PDC bits feature 98.8% hardness diamond compacts for extended drilling life.

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 250°C (sealing components) / -35°C to 215°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 500 operating hours; check for cracks, wear, or leakage, and replace damaged parts immediately to avoid safety incidents.

• Lubrication Protocol: Lubricate rig sprockets, transmission shafts, and clutch components with high-temperature lithium grease every 350 hours; replace hydraulic tank filters and diesel fuel filters every 1400 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: FZ35-35 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 (JK00309-26), 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 2 hours.

Case 2: ZQ203-100 Drill Pipe Clamp Jaw Plate Wear Fix

A desert drilling team reported frequent drill pipe slippage due to worn 2-7/8″ jaw plate assemblies (01.136.00B) on the ZQ203-100 power tong, causing operational delays and pipe damage. Installing our thickened, high-hardness jaw plate assembly restored clamping force, eliminated slippage, and extended jaw plate service life by 60% compared to standard parts.

Case 3: ZJ45J Rig Transmission Shaft Assembly Breakdown Resolution

A ZJ45J drilling rig suffered complete power transmission failure due to a damaged 1# unit and axle assembly, halting hoisting operations. Replacing the faulty transmission shaft assembly with our OEM-matched component restored torque transfer, fixed power delivery issues, and the rig operated flawlessly for 9+ months of continuous use with no recurring problems.
