Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive portfolio includes two core categories: precision mechanical spare parts and **high-performance oil well cement additives**. Mechanical parts cover ZJ series rig drive shafts, sprockets, friction hubs and brake components, 35×35/35×70 BOP rams, sealing rings, fasteners and repair kits, ZQ203 clamp cylinders, springs and bolts, FKQ640 control box transmitters and valves, F-series hydraulic tank seals and safety valves, GT350E/NK400E chassis fittings, wheel loader hydraulic repair kits and PDC drill bit accessories. Cement additives include M-19S coagulant, BSG-2 cement additive and NFA-25 anti-slump agent, designed to optimize cement slurry performance for reliable well cementation.

Each mechanical part carries a unique model identifier (JK00213-8, BA70001-12.07, YPQ-01-Z/25B, etc.) for quick identification and targeted procurement; cement 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 slurry performance verification before shipment to guarantee consistent quality and reliability.

2. Core Function Description

• BOP Well Control & Sealing: 35×35/35×70 BOP ram assemblies, sealing rings and dust rings provide stable pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; fasteners and repair kits maintain BOP structural integrity for long-term operation.

• Rig Power Transmission & Braking: ZJ series rig drive shafts, sprockets and friction hubs ensure smooth torque transfer for winch and turntable operation; brake discs, control cabinets and handles deliver precise, reliable braking control to avoid operational accidents and equipment damage.

• Drill Pipe Handling Stability: ZQ203 clamp lifting cylinders, springs and bolts enable secure, precise gripping and rotation of drill pipes; slip bolts and rib components enhance clamping force, minimizing pipe slippage and damage.

• Control & Hydraulic System Efficiency: FKQ640 shockproof transmitters and pressure regulators monitor and adjust system pressure in real time; hydraulic tank seals and safety valves prevent fluid leakage and maintain stable hydraulic pressure.

• Cement Slurry Optimization: M-19S coagulant regulates cement setting time, BSG-2 additive improves slurry fluidity, and NFA-25 anti-slump agent prevents slurry segregation, ensuring uniform and reliable well cementation.

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 85%.

• High-Temperature Wear-Resistant Materials: Load-bearing rig components use hardened alloy steel (70-76 HRC hardness); BOP seals use fluororubber composites that resist aging and cracking at -45°C to 320°C, with a 99.9% leak-proof rate under rated pressure.

• Modular Quick-Change Design: Wear-prone parts (BOP rams, clamp springs, brake discs) use a modular structure, reducing on-site repair time by 98% compared to traditional integrated parts.

• Stable Cement Additive Formulation: Cement additives use high-purity chemical raw materials, with excellent salt/calcium resistance and adaptability to high-temperature, high-pressure downhole environments.

• Cement Additive Usage Guidelines: Mix additives per API 10A dosage standards; test cement slurry performance before pumping, and adjust ratios based on downhole temperature and formation conditions.

• Storage Requirements: Store mechanical parts in a dry, dust-free environment (humidity ≤55%); seal cement 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.
