Fiber-optic Composite Logging Cable
11.8mm Optical Fiber Double Armored Logging Cable High Strength Oilfield Wireline Cable
11.8mm Fiber Optic Double Steel Wire Armored Logging Cable is designed for oilfield wireline operations, downhole monitoring and well intervention applications. It combines high-strength double steel wire armor with optical fiber communication technology to provide reliable data transmission, excellent tensile performance and superior resistance to harsh environments. The cable is suitable for deep well, high temperature and high pressure applications in oil, gas and geothermal exploration.
Key Specifications
Product Overview
Construction Description
The 11.8mm Fiber Optic Double Steel Wire Armored Logging Cable is specially designed for oil and gas well logging, downhole monitoring, and well intervention operations. The cable adopts a multi-layer structure that combines high-strength steel armor and optical fiber transmission technology to ensure excellent mechanical performance and stable data communication in harsh downhole environments.
Technical Description
Cable Construction (Inside to Outside)
- Optical Fiber Unit
- Single-mode or multi-mode optical fibers are placed inside a stainless steel tube filled with water-blocking gel to protect the fibers from moisture, vibration, and mechanical stress.
- Central Strength Member
- A high-strength steel wire rope or steel strand provides excellent tensile strength and supports deep well operations.
- Inner Bedding Layer
- Special insulating and cushioning materials protect the internal components and improve structural stability.
- Inner Steel Wire Armor Layer
- High-tensile galvanized steel wires are helically wound around the inner layer to provide mechanical protection and load-bearing capacity.
- Intermediate Separation Layer
- A protective separator layer minimizes friction between armor layers and enhances flexibility.
- Outer Steel Wire Armor Layer
- A second layer of high-strength galvanized steel wires is applied in the opposite lay direction to improve crush resistance, tensile performance, and durability.
- Outer Protective Coating
- An anti-corrosion polymer coating protects the cable against abrasion, chemicals, moisture, and harsh oilfield environments.
