• Drilling Fishing Tools: Retractable slip overshots (143mm/152mm) retrieve lost downhole tools and components safely; wire ropes provide reliable lifting for heavy drilling equipment.

• Industrial Auxiliary Materials: Industrial salt, caustic soda flakes, and clay stabilizers support drilling fluid preparation and wellbore conditioning; vehicle tires and all-in-one devices assist on-site logistics and data management.

3. Structural Features

• High-Temperature & Pressure Resistance: PEX150 sealing joints use multi-layer high-pressure seals, withstanding 35MPa downhole pressure; KClog circuit boards operate stably at 130°C, with anti-vibration mounting to resist downhole shock.

• Precision Electronic & Mechanical Design: KClog piezoelectric assemblies have high signal conversion efficiency; PEX150 slip rings ensure uninterrupted signal transmission during rotation; centralizers feature elastic double bows for adaptive centering in varying wellbore diameters.

• Durable Material Construction: Fishing tools and centralizers use high-strength alloy steel; logging tool connectors use corrosion-resistant metal; cementing plugs use wear-resistant rubber for long service life.

• Modular Quick Replacement: Logging circuit boards, sealing components, and cementing accessories are modular, allowing field technicians to complete replacements with standard tools in under 35 minutes.

4. Applicable Operating Conditions

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

• Pressure Range: Up to 35MPa for downhole logging and cementing operations

• Temperature Adaptation: -45°C to 135°C, suitable for deep wells, arctic, and desert oilfields

• Load Capacity: Centralizers support 8-40 ton casing loads; wire ropes bear 1670kN lifting force

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

• Certifications: API downhole instrument standards, cementing equipment specifications, and electronic component reliability norms

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

• Logging Tool Electronics: Inspect KClog circuit boards for dust and corrosion after each logging run; clean piezoelectric assemblies with lint-free cloths; calibrate PEX150 tension instruments every 2 downhole trips; store electronic components in dry, anti-static ABS boxes.

• Downhole Sealing & Mechanical Parts: Replace PEX150 sealing joints every 1000 operating hours; lubricate centralizer springs with high-temperature grease quarterly; inspect fishing slip overshots for wear and replace worn slips promptly.

• Cementing Tools: Clean cement residue from rubber plugs and floating collars after use; pressure-test cementing components before deployment; store cement additives in dry, sealed containers to avoid moisture absorption.

• Auxiliary Materials: Check wire rope for broken strands monthly; rotate vehicle tires regularly to ensure even wear; avoid exposing industrial chemicals to direct sunlight and moisture.

Authoritative Quality Endorsement & Exclusive Field Data

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

• KClog 9650 series circuit boards maintain stable signal transmission for 1300 consecutive downhole operating hours

• PEX150 rotary high-pressure sealing joints achieve zero fluid leakage for 1100 hours under 35MPa pressure
