An optical cable connecting device special for an oil field is composed of a first outer steel tube fixing and sealing device, a sleeve, a second outer steel tube fixing and sealing device, a first inner steel tube fixing device, an inner connecting tube and a second inner steel tube fixing device. Metal deformation of a copper ferrule is used, a front casing tube, a rear casing tube and the inner connecting tube are connected through threads, and the outer diameter of an inner steel tube of an optical cable and the outer diameter of an outer steel tube of the optical cable are different, so that the inner steel tube of the optical cable is fixed. The outer steel tube of the optical cable is doubly fixed and sealed through metal deformation of an inner conic ferrule and an outer conic ferrule. The exposed optical cable is sealed powerfully and thread looseness is prevented through metal deformation of the conic end face at a second end of a reducing connecting tube. According to the optical cable connecting device special for the oil field, the problem that the inner steel tube and the outer steel tube bounce on the connecting portion of the optical cable is well solved and the exposed optical cable and melting points are well sealed and protected.
Description
technical field [0001] The invention relates to a connecting device for connecting two sections of optical cables, and is especially suitable for connecting special optical cables and optical cables in oil fields. Background technique [0002] At present, from the perspective of world energy consumption trends, oil and gas are still the mainstay. The monitoring of parameters such as oil and gas well pressure and temperature is usually realized by electronic products, but the environment of oil and gas wells is extremely complex, mostly high temperature, high pressure and corrosive, making Electronics have extremely limited long-term stability and reliability. Due to the inability to conduct real-time and high-precision monitoring of downhole parameters, well shutdowns caused by failures such as wax plugging, water ingress, and sand outflow occur from time to time. The recovery rate of oil and gas wells is only about 30%, which not only causes waste of resources, but also cos...
