1-FT-350-11/14-HS-19-ETFJ Cable Technical Data

1-FT-350-11/14-HS-19-ETFJ Cable Feature

• Exceptional High-Temperature Resistance: After grease removal, the cable is no longer constrained by grease carbonization temperatures (typically around 175°C/347°F). The materials used in the ETFJ structure itself can withstand temperatures far exceeding this threshold (often reaching 230°C/446°F or higher), making it ideal for high-temperature wells.
• Superior Pressure Resistance and Sealing: ETFJ encapsulation technology provides a robust radial pressure barrier, effectively preventing high-pressure wellbore fluids from infiltrating the conductor and safeguarding signal integrity.
• Environmentally friendly and clean: Completely eliminates environmental pollution from grease leaks, as well as oil contamination of well sites and equipment, reducing cleanup costs and waste disposal issues.
• More stable electrical performance: Removes grease, which can affect capacitance and resistance with temperature changes, resulting in more stable electrical parameters for the cable and facilitating high-quality signal transmission.
• Weight Reduction and Simplified Maintenance: Eliminates grease injection equipment and procedures, lowering transport weight while streamlining field preparation and maintenance tasks.
• Reduced Gas Permeation: The solid-state encapsulation structure more effectively blocks the permeation of combustible downhole gases (such as H₂S and methane) through the cable into the blowout preventer housing, enhancing operational safety.
