OEC Logging Cable for Oilfield Logging

Structure Description

The OEC Logging Cable is designed for engineering and production logging operations in demanding downhole environments. Its multi-layer structure provides excellent tensile strength, corrosion resistance, high-temperature endurance, and reliable signal transmission performance. The cable structure includes:

1. Steel Wire Armor
   • High-strength steel wire armor provides superior tensile strength and mechanical protection.
   • The armored layer enhances resistance to pulling force, abrasion, impact, crushing, and external pressure during cable deployment and downhole operations.
   • It ensures stable performance in deep well and complex geological conditions.
2. Conductor
   • The conductor consists of high-quality bare copper wire and an optical fiber tube.
   • Bare copper wire provides excellent electrical conductivity for power supply and signal transmission.
   • The optical fiber tube enables high-speed data communication and supports advanced logging and monitoring applications.
3. Insulation Layer
   • High-temperature resistant and oil-resistant insulation materials are applied around the conductors.
   • The insulation layer ensures stable electrical performance, prevents leakage, and protects internal conductors from moisture, chemicals, and downhole fluids.
4. Sealing Structure
   • A reliable sealing system is designed to prevent the penetration of water, oil, gas, and corrosive fluids.
   • The sealing structure improves pressure resistance and protects the internal components during long-term operation in harsh downhole environments.
5. Outer Sheath
   • The outer sheath is manufactured from durable corrosion-resistant and wear-resistant materials.
   • It provides additional protection against mechanical damage, temperature changes, and chemical exposure.
