Structured Product Description & Operational Details

1. Product Introduction

This collection features 50+ high-demand oilfield parts spanning PEX150 logging tool accessories (rotating high-pressure balance seal groups, downhole tension sensors), KClog dipole acoustic logging tool circuit boards and components, cementing tool joints (XJT193.67, CSG-N casing testers), casing scrapers (GX-series), drill adapters (NC-threaded, inner flat models), PFF35-103 35MPa high-pressure valves, WL215.9 drill stabilizers, winches, chemical additives, and hand tools. All parts are fabricated from high-grade 4130 forged steel, corrosion-resistant downhole alloys, and industrial-grade electronic components, undergoing full material testing and dimensional verification to ensure zero-modification fitment with targeted equipment. Brand-certified components (Stanley wrenches, HP printers, Kunlun hydraulic oil) further guarantee consistent quality and performance.

2. Function Description

• PEX150 Logging Tool Components: High-pressure balance seal groups prevent downhole fluid intrusion; tension shells/sensors monitor downhole tensile force in real time; rotating housings and scale devices maintain stable logging instrument rotation and data calibration for accurate neutron-lithology density readings.

• KClog Dipole Acoustic Logging Parts: DSP circuit boards, power boards, and transformer assemblies enable stable acoustic signal transmission and data processing; remote thermos flasks and isolation connectors protect electronic components from extreme downhole temperatures and vibration.

• Cementing & Casing Tools: XJT193.67 circulation joints facilitate smooth cementing fluid flow; CSG-N pressure test joints verify casing sealing integrity; GX-series scrapers remove debris and scale from casing inner walls to ensure cement bonding quality.

• Drilling & Connection Parts: Multi-spec NC-threaded adapters enable seamless connection between different-diameter drill pipes; WL215.9 stabilizers control well deviation; orientation joints adjust drill string direction; PFF35-103 valves regulate 35MPa high-pressure wellbore fluids safely.

• On-Site Auxiliary & Chemical Products: TGS logging winches support logging tool hoisting; WFA-1 release agent prevents downhole jamming; drilling fluid additives stabilize mud performance; hand tools and winch repair kits streamline on-site maintenance.

3. Structural Features

• High-Pressure Sealing Design: PEX150 seal groups use multi-layer lip seals and corrosion-resistant gaskets, withstanding 35MPa downhole pressure without leakage; API 6A valves feature forged 4130 steel bodies for pressure retention.

• Precision Thread & Dimensional Machining: Adapters and orientation joints use standard NC (411, 52, 38) and regular threads, with dimensional tolerance controlled within 0.015mm to eliminate thread slippage and loose connections.

• Shock & Temperature Resistance: KClog electronic boards have anti-vibration mounting; downhole sensors operate stably under extreme vibration and high temperatures; scraper blades use wear-resistant alloy for long service life.

• Modular Replacement Design: Logging tool components, winch seal kits, and valve parts are modular, allowing field technicians to complete replacements with standard tools in under 40 minutes.

4. Applicable Operating Conditions

All components are field-validated for reliable performance in harsh oilfield environments, complying with global industry standards:

• Pressure Range: 1.6MPa low-pressure cementing to 35MPa high-pressure well control (API 6A rated)

• Temperature Adaptation: -40°C to 135°C, suitable for arctic, desert, and deep well operations

• Load Capacity: Adapters/stabilizers support 10-60 ton drill string loads; winches handle 10,000,000mm cable length

• Environment: Corrosive drilling fluid, high-vibration downhole, offshore salt spray, and sandy desert conditions

• Certifications: API 6A, downhole instrument safety standards, and mechanical connection specifications

5. Maintenance & Care Recommendations (Field Engineer Tips)

• Logging Tool Components: Inspect PEX150 seal groups for wear after each downhole run; clean KClog circuit boards with lint-free cloths and anti-static spray; calibrate tension sensors every 3 logging cycles to maintain accuracy.

• Drilling & Valve Parts: Lubricate adapter threads with high-temperature anti-seize compound before connection; flush PFF35-103 valve cavities with clean fluid every 2 months; inspect stabilizer blades for wear and replace at 1mm wear depth.

• Cementing & Scraper Tools: Clean scraper blades of casing debris after each use; pressure-test cementing joints before deployment; replace seal rings on circulation joints annually to prevent leakage.

• Auxiliary Equipment: Change Kunlun No.10 hydraulic oil every 1500 winch operating hours; store electronic components in dry, temperature-controlled cases; inspect winch seal kits for deterioration quarterly.

Authoritative Quality Endorsement & Exclusive Field Data

All products undergo third-party laboratory testing and on-site field validation, adhering to API 6A, downhole electronic instrument, and mechanical engineering standards. Exclusive operational data confirms:

• PEX150 rotating high-pressure balance seal groups maintain zero leakage for 1200 consecutive downhole operating hours

• KClog DSP circuit boards deliver stable data transmission with zero signal loss under 8G downhole vibration
