G1FB-4.0 0.157"， MONOCONDUCTOR 316L/825 ARMOR, 16 AWG TEC Cable
Core Applicable Well Types and Operation Scenarios
1. High-Temperature Geothermal Wells and Medium-Deep Well Logging Operations
Applicable Conditions: Straight or directional wells with downhole temperatures of 120℃–260℃ and well depths of 1500–5000 meters.
Compatible Operations: Geothermal resource exploration, formation parameter measurement (temperature, pressure, resistivity), and high-temperature reservoir evaluation.
2. Perforation and Coring Operations in Low-Sulfur Oil and Gas Wells
Applicable Conditions: Low-sulfur oil and gas wells with H₂S partial pressure ≤ 0.1 MPa and CO₂ partial pressure ≤ 0.3 MPa; well depths ≤ 5000 meters, moderate downhole friction, and no extreme high-pressure conditions.
Compatible Operations: Signal transmission and depth control during perforation construction and coring operations in low-sulfur oil and gas wells.
3. Onshore High-Temperature Exploration Wells and Geological Monitoring
Applicable Conditions: Onshore high-temperature exploration wells and shale gas development wells with stable formation temperature and pressure, and weakly corrosive media.
Compatible Operations: Initial evaluation of high-temperature formations, multi-parameter logging after completion, and geological dynamic monitoring.
4. Routine Workover and Restart Operations in Medium-Deep Wells
Applicable Conditions: Mature old wells with only slight scaling or minor borehole constriction; downhole temperatures ≤ 260℃, weak corrosion (H₂S partial pressure ≤ 0.1 MPa, CO₂ partial pressure ≤ 0.3 MPa).
Compatible Operations: Casing integrity detection of high-temperature old wells, auxiliary scraping operations for shallow wells, and basic logging verification before restart.
Strictly Inapplicable Scenarios
1. Strong-corrosion wells (H₂S partial pressure > 0.1 MPa or CO₂ partial pressure > 0.3 MPa).
2. Ultra-high-temperature wells (continuous temperature > 280℃).
3. High-curvature horizontal wells (curvature radius < 300 m) and high-friction working condition wells.
4. Offshore oil and gas wells and high-salt-spray environments.
5. High-pressure well testing and heavy oil well operations.
