Photoelectric composite cable connector for oil well annulus test

Abstract

The invention discloses a photoelectric composite cable connector for an oil well annulus test, and relates to the technical field of the photoelectric composite cable connector for the oil well annulus test, which is matched with a photoelectric composite cable and a spiral winding type optical fiber composite cable connector for use, and the photoelectric composite cable connector comprises an upper joint and is characterized in that the upper joint is in a pipe sleeve shape; a photoelectric composite cable penetrates through the upper connector, the minimum inner hole diameter of the upper connector is consistent with the outer diameter of the photoelectric composite cable, the upper end of the upper connector is provided with internal threads and a sealing ring groove, and the lower end of the upper connector is provided with an inner taper hole, internal threads and a sealing ring face. The photoelectric composite cable connector is reasonable in structural design and convenient to use, optical fiber welding and wire connection of a photoelectric composite cable can be achieved through the connector, large axial tension can be borne, and the problems of optical fiber welding, wire connection and fixing of the large axial tension of the photoelectric composite cable are solved.

Description

technical field [0001] The invention relates to the technical field of a photoelectric composite cable connector used in conjunction with a photoelectric composite cable and a spiral-wound optical fiber composite cable connector for oil well annulus testing, in particular to a photoelectric composite cable connector for oil well annulus testing . Background technique [0002] The optical fiber composite cable connector is mainly used for optical fiber fusion and wire connection of the optical fiber composite cable and the spiral wound optical fiber composite cable connector. The spiral wound optical fiber composite cable matched with the spiral wound optical fiber composite cable connector can be used on the ground or oil well Semi-permanent monitoring or permanent monitoring of parameters such as temperature, pressure, flow rate, vibration, sound wave, strain, etc. in annulus testing. [0003] At present, the existing photoelectric composite cables at home and abroad mainl...
