WGSF46-5.6 MONOCONDUCTOR ( 7/32" ) AWG 17 Wireline Logging Cable
Core Applicable Well Types and Operation Scenarios
1. High-Temperature Geothermal Wells and Ultra-Deep Well Logging Operations
Applicable Conditions: Straight or directional wells with downhole temperatures of 100℃~232℃ and well depths of 2,000~6,000 meters.
Compatible Operations: Geothermal resource exploration, parameter measurement (temperature, pressure, resistivity) of ultra-deep formations, 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 ≤ 6,000 meters, with 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 wells; meets the power supply and load-bearing requirements for tools and equipment.
3. Onshore High-Temperature Exploration Wells and Geological Monitoring
Applicable Conditions: Onshore high-temperature exploration wells, shale gas/coalbed methane development wells, with stable formation temperature and pressure, and no strong corrosive media.
Compatible Operations: Initial evaluation of high-temperature formations, multi-parameter logging after drilling and 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 ≤ 232℃ and no strong corrosion.
Compatible Operations: Casing integrity testing of old wells, auxiliary scraping operations for shallow wells, and basic logging verification before restart.
