Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive portfolio includes two core categories: precision mechanical spare parts and high-performance drilling fluid additives. Mechanical parts cover ZJ series rig input shafts, sprockets, friction wheels and brake components, 35×35/35×70 BOP sealing rings, ram assemblies, fasteners and bearings, ZQ203 clamp jaw plates, valves and connectors, FKQ6406 control box transmitters and valves, F-series hydraulic tank fittings and filters, and diesel engine sensors, filters and hoses. Fluid additives include CHM macromolecular cationic coating inhibitors, DEVIS viscosity reducers, QS-2 ultrafine calcium carbonate blocking agents and LV-PAC polyanionic cellulose, designed to stabilize drilling fluid and protect wellbores.

Each mechanical part carries a unique model identifier (BA70011-04.00, JK00213-44, YPQ-01-Z/40B, etc.) for quick identification; fluid additives feature standardized formulation ratios for easy on-site mixing. Raw materials and chemical formulations are selected for extreme oilfield resilience, with every unit undergoing strict pressure testing, dimensional inspection or fluid performance verification before shipment to guarantee consistent quality and reliability.

2. Core Function Description

• BOP Well Control & Sealing: 35×35/35×70 BOP O-rings, ram assemblies and fasteners provide stable pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; thrust bearings and hinge components enable smooth BOP door operation.

• Rig Power Transmission & Braking: ZJ series rig input shafts, sprockets and friction wheels ensure smooth torque transfer for winch and turntable operation; brake handles, coils and sealing rings deliver precise, reliable braking control to avoid operational accidents.

• Drill Pipe Handling Stability: ZQ203 clamp jaw plates, rollers and valves enable secure, precise gripping and rotation of drill pipes; relief valves and connectors maintain stable hydraulic pressure, minimizing pipe damage and handling hazards.

• Control & Hydraulic System Efficiency: FKQ6406 shockproof transmitters and air valves monitor and regulate system pressure in real time; hydraulic tank filters and fittings prevent fluid contamination and leaks, maintaining stable system operation.

• Drilling Fluid Optimization: CHM coating inhibitors form a protective film on wellbores to prevent collapse; viscosity reducers and PAC additives improve fluid flow and reduce filtration loss, adapting to complex geological formations.

3. Structural & Material Features

• Ultra-Precision CNC Machining: All mechanical structural parts feature ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation, cutting installation time by 82%.

• Reinforced High-Temperature Sealing: BOP and hydraulic sealing rings adopt fluororubber and nitrile rubber composites, resisting aging and cracking at -45°C to 315°C, with a 99.9% leak-proof rate under rated pressure.

• High-Strength Wear Resistance: Load-bearing rig components use hardened alloy steel (69-75 HRC hardness); clamp jaw plates and BOP rams use wear-resistant alloy coatings to extend service life.

• Stable Chemical Formulation: Drilling fluid additives use macromolecular cationic polymers and ultrafine mineral fillers, with excellent salt/calcium resistance and long-term stability in high-temperature formations.

• Additive Usage Guidelines: Mix CHM inhibitor and PAC additives per API 13A dosage standards; test drilling fluid performance every 12 hours during drilling, and adjust additive ratios based on formation conditions.

• Storage Requirements: Store mechanical parts in a dry, dust-free environment (humidity ≤55%); seal fluid additives in airtight containers away from direct sunlight and moisture to preserve formulation stability.

• Installation Standards: Follow API rig maintenance specs for torque tightening; use specialized tools for seal installation to avoid damage; calibrate control box transmitters post-installation for accurate pressure monitoring.

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

Case 1: ZJ32L6 Input Shaft Failure Repair

A land drilling rig experienced winch power transmission failure and stalling due to a worn ZJ32L6 input shaft (BA70011-04.00), halting hoisting operations. Replacing the damaged shaft with our forged alloy steel component restored smooth torque transfer, eliminated stalling, and the winch operated flawlessly for 24+ months of continuous use.

Case 2: FKQ6406 Pressure Transmitter Malfunction Fix

An offshore drilling platform faced unstable hydraulic pressure monitoring and false system alarms due to a faulty FKQ6406 shockproof transmitter (YPQ-01-Z/40B), disrupting rig control. Installing our calibrated transmitter restored real-time pressure tracking, eliminated alarms, and the control system maintained stable performance for 23+ months.

Case 3: CHM Inhibitor Wellbore Stabilization Solution

A complex formation drilling project suffered severe wellbore collapse and high filtration loss, delaying operations. Adding our CHM macromolecular cationic coating inhibitor to the drilling fluid formed a protective wellbore film, reduced filtration loss by 72%, and resumed safe drilling within 4 hours.
