Structured Product Description & Operational Details

1. Product Introduction

This collection features 50+ high-demand oilfield parts spanning Z23Y/Z23X/PFFY high-pressure well valves (35MPa/70MPa), PHP/SHR-HP/SOS 204℃ high-temperature packers, XJT casing circulation joints (177.8mm/244.5mm/273.1mm), ZJ30/ZJ40/ZJ50/ZJ70 rig brake accessories, cementing plugs/floating shoes, drill pipe adapters, and well testing tools. All high-pressure valves adopt ASTM 4130 forged steel; packers use high-temperature fluororubber seals; brake components use wear-resistant friction materials; cementing tools follow API standard machining, ensuring zero-modification fitment and stable performance in harsh high-temperature, high-pressure, and heavy-load drilling environments.

2. Function Description

• High-Pressure Well Valves: Z23Y/PFFY series valves regulate and shut off high-pressure wellbore fluid (35MPa/70MPa), preventing blowouts and ensuring well control safety; forged steel construction withstands extreme pressure and corrosion.

• High-Temperature Packers: PHP/SHR-HP/SOS packers seal annulus spaces at 204℃/70MPa, realizing downhole zonal isolation for well completion and testing operations; adaptable to multiple casing sizes (103.38mm-173mm).

• Cementing Tools: XJT circulation joints facilitate smooth cementing fluid flow; floating shoes/hoops prevent cement backflow; self-locking rubber plugs and impact seats ensure efficient cementing displacement and sealing.

• Rig Brake Components: ZJ series brake friction plates, bolts, and repair kits ensure stable rig braking; Eaton auxiliary brake parts enhance braking performance for heavy-duty drilling rigs; sealing rings prevent brake fluid leakage.

• Drilling & Testing Tools: Threaded adapters realize seamless drill pipe connection conversion; tubing plugs and anchor cannulas assist well testing operations; hydraulic anchors secure downhole tool positioning.

3. Structural Features

• High-Pressure & Temperature Resistance: Packers and valves use metal-to-metal sealing and high-temperature rubber, withstanding 204℃ and 70MPa without deformation or leakage; valves meet API 6A forging standards.

• Wear-Resistant Brake Design: Dynamic/static friction plates use high-friction, low-wear materials; brake bolts and nuts adopt high-strength alloy steel, resisting fatigue under heavy-load braking.

• Precision Thread Machining: Adapters and circulation joints follow API TBG/thread standards, with dimensional tolerance within 0.015mm to eliminate thread slipping and loose connections.

• Modular Quick Replacement: Brake repair kits, valve seals, and packer components are modular, allowing field technicians to complete replacements with standard tools in under 35 minutes.

4. Applicable Operating Conditions

All products are field-tested and certified to operate reliably in extreme oilfield environments, complying with strict international API and mechanical safety standards:

• Pressure Range: 35MPa-70MPa for well valves and packers, matching API 6A pressure ratings

• Temperature Adaptation: -40℃ to 204℃, suitable for deep wells, ultra-deep wells, desert, and offshore oilfields

• Load Capacity: Brake components handle 80-120 ton rig braking load; packers support 10-60 ton downhole pressure load

• Environment: Corrosive drilling fluid, high-vibration rig operation, offshore salt spray, and high-salt formation conditions

• Certifications: API 6A, API 11D1, rig mechanical safety standards, and explosion-proof electrical norms

5. Maintenance & Care Recommendations (Field Engineer Practical Tips)

• High-Pressure Valves: Flush valve cavities with clean fluid quarterly; inspect valve seats for wear monthly; replace sealing components every 1200 operating hours to prevent leakage.

• Packer Components: Clean packer sealing surfaces before deployment; apply high-temperature anti-seize grease; inspect rubber seals for cracks after each use, replace damaged parts immediately.

• Rig Brake Parts: Lubricate brake bolts and springs monthly; replace friction plates at 1mm wear depth; check brake fluid levels weekly and replace Kunlun 7103HZY3 fluid every 1500 operating hours.

• Cementing & Adapter Tools: Clean cement residue from circulation joints after use; coat adapter threads with anti-rust oil; store thread components in dry, dust-proof cases to avoid wear.

Authoritative Quality Endorsement & Exclusive Field Data

All products undergo third-party laboratory testing and on-site field validation, adhering to API, international oilfield, and mechanical manufacturing standards. Exclusive operational data confirms:

• PFFY70-103 valves maintain zero leakage for 1800 consecutive operating hours at 70MPa pressure

• SHR-HP 204℃ packers retain stable sealing for 1600 hours in ultra-deep high-temperature wells

• ZJ series brake friction plates last 2200 braking cycles without significant wear

• XJT 177.8mm circulation joints achieve unobstructed cement flow at 500L/min flow rate

Each batch passes 24 strict quality checkpoints, including pressure endurance testing, high-temperature aging testing, material composition analysis, and dimensional precision verification, ensuring 92.5% product compatibility and long-term operational reliability.
