Product Details

Applicable Well Types

1 Cased Hole Short-Distance Logging & Monitoring Wells (Best Match)

Well conditions: Conventional cased wells (φ114 mm to φ139.7 mm casing), well depth ≤ 5500 m, bottomhole temperature ≤ 150℃. Used for internal wiring of downhole tools and short-distance signal transmission between sensors and the main control unit.

2 MWD/LWD Tool Internal Connection Wells

Well conditions: Medium-deep vertical wells and low-deviation directional wells (inclination ≤ 45°), well depth ≤ 5500 m, bottomhole temperature ≤ 150℃, with no severe vibration or torsion. Suitable for signal transmission inside measurement-while-drilling tools.

3 Production Logging Tool String Connection Wells

Well conditions: Cased production wells, water injection wells, and gas injection wells, well depth ≤ 5500 m, bottomhole temperature ≤ 150℃. Used for connecting multiple sensors (flow rate, pressure, temperature) in production logging tool strings.

4 Medium-Temperature Geothermal & Hydrogeological Monitoring Wells

Well conditions: Medium-shallow geothermal wells and hydrogeological exploration wells, well depth ≤ 4500 m, bottomhole temperature ≤ 150℃. Suitable for multi-parameter monitoring signal transmission in limited space.

5 Coalbed Methane & Mine Underground Detection Wells

Well conditions: Shallow coalbed methane wells (≤ 2000 m) and mine underground small-diameter detection wells, temperature ≤ 150℃, narrow space. Suitable for flat cable layout in limited tool space.

Strictly Inapplicable Scenarios

High-Deviation Wells (> 45°) / Long Horizontal Section Wells.

Ultra-Deep Wells (> 6000 m) — The 12 kN breaking strength is insufficient to bear the total tension of long-distance self-weight and tool load, leading to a high breakage risk.

High-Temperature Wells (> 150℃).

Severe Corrosive Wells with High H₂S/CO₂ Concentration.

Heavy-Duty Main Logging Cable Applications — It is designed for internal connection and short-distance transmission, not suitable for serving as the main cable for heavy instrument lowering.

Frequently Asked Questions

What is the maximum well depth this cable is rated for?

This cable is rated for well depths up to 5500 m under standard operating conditions. For ultra-light load scenarios, it may be used up to 6000 m; however, applications exceeding 6000 m are strictly not recommended due to insufficient breaking strength (12 kN) to support the cumulative self-weight and tool load over long distances.

Can this cable be used in high-temperature geothermal wells above 150℃?

No. The cable's rated maximum operating temperature is 150℃. Deployment in wells where bottomhole temperature exceeds 150℃ is strictly inapplicable, as it may cause insulation degradation and signal failure. For higher-temperature environments, a cable with a higher thermal rating should be selected.

Is this cable suitable for horizontal or high-deviation directional wells?

This cable is suitable for vertical wells and low-deviation directional wells with an inclination angle of 45° or less. It is strictly not recommended for high-deviation wells (inclination > 45°) or long horizontal section wells, as the flat profile and mechanical properties are not designed to handle the torsional and frictional stresses present in such trajectories.

How many signal channels does this cable support, and what types of sensors can it connect?

The cable features an 11-core conductor configuration, enabling simultaneous multi-signal transmission. It is well-suited for connecting multiple sensors within a single tool string, including flow rate sensors, pressure sensors, and temperature sensors, making it ideal for production logging tool string applications.

Can this cable be used as the main logging cable for lowering heavy instruments?

No. This cable is specifically engineered for internal tool connections and short-distance signal transmission within downhole tool assemblies. It is not designed to serve as a main logging cable for lowering heavy instruments, as its 12 kN breaking strength is insufficient for heavy-duty load-bearing applications over long cable runs.

Is this cable compatible with coalbed methane wells and mine underground detection applications?

Yes. This cable is well-suited for shallow coalbed methane wells (depth ≤ 2000 m) and mine underground small-diameter detection wells where temperature does not exceed 150℃. Its flat profile and compact structure make it particularly advantageous for deployment in narrow-space environments where conventional round cables cannot be easily routed.
