    Frequently Asked Questions
    Q
    What is the maximum well depth this photoelectric composite cable is rated for?
    The cable is rated for a maximum well depth of 8,000m. Beyond this depth, the mechanical safety margin is exceeded and deployment is strictly not recommended to ensure operational safety and cable integrity.
    Q
    What is the maximum temperature rating, and what insulation material is used?
    The cable is rated to a maximum continuous operating temperature of 200℃ (392℉). It uses a PI (polyimide) insulation layer, which provides long-term stability and prevents aging at this temperature. Wells exceeding 200℃ are strictly outside the application scope.
    Q
    Can this cable be used in highly corrosive downhole environments with H₂S and CO₂?
    The cable features PI encapsulation combined with corrosion-resistant materials, providing good resistance to H₂S, CO₂, and Cl⁻ environments under standard conditions. However, extremely severe corrosion environments without additional special anti-corrosion treatment fall outside the applicable scope.
    Q
    Is this cable suitable for horizontal shale gas wells with long horizontal sections?
    Yes. The cable is designed for extra-long radius horizontal wells with horizontal sections up to 2,500m. It is well-suited for deep shale gas horizontal well fracturing monitoring and production monitoring. Short-radius horizontal wells or wells with sharp dogleg severity are not compatible.
    Q
    What are the key mechanical strength specifications of this cable?
    The cable has a breaking strength of 74kN and a maximum working tension of 37kN, providing a 1:2 safety factor. The minimum bending diameter is 1,000mm. It features excellent flexibility, torsion resistance, and anti-wear performance suitable for high-tension ultra-deep well operations.
    Q
    What fiber types are integrated in the photoelectric composite cable?
    The cable integrates 2 single-mode (B1) fibers and 2 multi-mode (A1a) fibers within a photoelectric composite structure. This configuration supports simultaneous DTS/DAS optical signal transmission and downhole tool power supply, conforming to GF standards with a high-strength armored design.
