G1F46-3.18 1/8"， MONOCONDUCTOR 316L/825 ARMOR, 18 AWG TEC Cabl
Applicable Well Types：
1.Small-Bore/Micro-Bore Wells (Best Matching Core Advantage)
Well Condition Features: Wellbore diameter ≤ 100mm, thin-walled casing wells (e.g., φ73mm/φ89mm casing), small-diameter open holes, and medium-shallow wells with depth ≤ 2000m.
2. Medium-Temperature Corrosive Oil & Gas Wells (Matching Temperature Resistance + Corrosion Resistance)
Well Condition Features: Conventional/unconventional shallow oil & gas wells with bottomhole temperature of 150℃-200℃, containing corrosive media such as H₂S/CO₂/Cl⁻, and well depth of 1000-3000m.
3.Medium-Shallow Conventional Vertical Wells/Low-Deviation Directional Wells
Well Condition Features: Vertical wells or low-deviation directional wells with build-up sections ≤ 45°, well depth ≤ 3000m, bottomhole temperature ≤ 200℃, and no complex trajectories with high torque or friction.
4. Shallow Geothermal Wells/Medium-Temperature Hydrogeological Wells
Well Condition Features: Medium-temperature shallow geothermal wells and hydrogeological exploration wells with bottomhole temperature of 120℃-200℃, well depth ≤ 2500m, and some intervals containing high-salinity formation water.
5. Shallow Coalbed Methane Wells/Underground Coal Mine Logging Wells
Well Condition Features: Shallow coalbed methane development wells (depth ≤ 1500m) and small-diameter detection wells in underground coal mines, with environments containing trace methane and highly corrosive formation water.
Strictly Inapplicable Scenarios
1. High-deviation wells (>60°)/long-horizontal-section horizontal wells (horizontal section >500m).
2. Deep/ultra-deep wells (depth >4000m).
3. Ultra-high temperature wells (bottomhole temperature >200℃).
4. Tool weight >80kg will quickly exceed the maximum recommended working tension (2.75kN), significantly reducing cable service life or causing immediate breakage.
5. Large-bore wells (wellbore diameter >200mm).
