W7FPP-11.8 Steel-Wire Armored Fluoroplastic Detection Cable works together with well testing trucks and layered injection & production systems. The cable provides stable power supply to downhole measuring instruments and transmits acquired underground signals to surface data acquisition systems, and suspends downhole measuring equipment during running and pulling operations. Adopting special composite structure with high-temperature cable threaded through solid stainless steel sheath, it delivers steady and reliable wellhead blowout prevention sealing capacity and outstanding resistance against oil & gas medium corrosion. Built-in thermocouple wires and optical fiber units, this cable is mainly used for long-term continuous temperature monitoring in gas injection wells and observation wells. With its superior structural characteristics, it is also suitable for direct-reading dynamic testing of various oil and gas wells, widely adopted for formation monitoring and layered produc…
