High-Temperature Resistant G1FF-6.35 Single-Conductor Logging Cable - China Suppliers and Factory
🛢️ Applicable Well Types
1 Standard Cased Hole Logging Wells (Best Match)
Well Condition Features: Conventional casing wells (such as φ114 mm, φ127 mm, φ139.7 mm casing), well depth ≤ 5500 m, bottomhole temperature ≤ 200℃, pressure ≤ 100 MPa.
2 200℃ Medium-High Temperature Oil & Gas Wells & Gas Wells (Matching Temperature Resistance + Corrosion Resistance)
Well Condition Features: Vertical and low-deviation directional wells with inclination ≤ 45°, well depth ≤ 5500 m, bottomhole temperature up to 200℃, medium formation pressure, no severe corrosion.
3 Production Logging & Dynamic Monitoring Wells
Well Condition Features: Cased production wells, water injection wells, oil & gas production wells; used for flow rate, water cut, pressure, temperature, casing damage detection, and cement bond logging.
4 Medium-Deep Open-Hole Exploration & Evaluation Wells
Well Condition Features: Medium-deep open-hole wells, well depth ≤ 5500 m, temperature ≤ 200℃, pressure ≤ 100 MPa, moderate formation conditions.
5 Medium-High Temperature Hydrogeological & Geothermal Monitoring Wells
Well Condition Features: Hydrogeological exploration wells, medium-temperature geothermal wells, temperature ≤ 200℃, well depth ≤ 5000 m, some with high-salinity formation water.
🚫 Strictly Inapplicable Scenarios
1. High-deviation wells (> 60°) / long horizontal section wells / high dogleg severity wells.
2. Ultra-deep wells (> 6000 m) — 10 kN breaking strength is insufficient.
3. Ultra-high temperature wells (> 200℃) — Over-temperature causes fluoroplastic insulation aging, melting or failure, leading to insulation damage and short circuits.
4. Severe corrosive wells with high H₂S/CO₂ concentration — Standard steel pipe armor has limited resistance to sour gas corrosion, leading to rapid material deterioration and failure.
