An encapsulated tubular cable with a colorized identification strap includes armored protection ducts and an encapsulation protection layer. A hollow passage is formed in the center of the duct body after each armored protection duct is formed. A wire cable, an optical fiber, or an oil duct is placed in the hollow passage. The encapsulation protection layer wraps the armored protection ducts. A plurality of armored protection ducts are arranged in one encapsulated protection layer. A peripheral edge of each armored protection duct is correspondingly provided with at least one colorized identification strap group. The encapsulation protection layer improves the corrosion resistance of the encapsulated duct cable; the colorized identification straps are provided at the thinnest positions of the encapsulation protection layer to facilitate tearing and encapsulation; and each colorized identification strap has a respective color identifier, which is convenient for distinguishing objects in each hollow passage during use.

A method of assembling an optical fiber cable on production casing includes positioning the optical fiber cable against a production casing at a hole of a well site, and affixing the optical fiber cable against the production casing by applying an adhesive to the production casing to secure the optical fiber cable against the production casing. The method further includes applying pressure to the adhesive to adhesively bond the optical fiber cable to the production casing along a length of the production casing while the production casing is being run-in-hole.

Method and Equipment for Installing a Power Cable in a Deployment Site The present disclosure relates to a method for installing a single power cable span in a deployment site comprising a rail for supporting the single cable span by trolleys, the method comprising the steps of providing a conveyor belt outside of the deployment site, the conveyor belt having a plurality of locations set at a predetermined distance one from the other along a longitudinal movement direction of the conveyor belt and moving integrally with the latter; repeating the following steps until the single cable span reaches a predetermined position while the conveyor belt is moving, positioning a first part of a holder at one of the locations; while advancing the single cable span, laying a portion thereof on said first part of the holder positioned at the location moving with the conveyor belt; connecting a second part of the holder to the first one to lock the cable span portion in between; while the cable span portion locked by the holder is leaving the conveyor belt, removing the first part of the holder from the location moving with the conveyor belt. According to another aspect, the present disclosure relates to an equipment for the installation of a single power cable span in a deployment site.

Various embodiments include methods and apparatus structured to install an optical fiber cable into a well at a well site. In a from-bottom-to-top embodiment, an anchor deployed at a selected location in a hole of the well can be used and the optical fiber cable can be pulled up to a surface of the well from the selected location. In a from-top-to-bottom embodiment, an optical fiber cable can be moved down from the surface until an end of the optical fiber cable is locked at a selected location by a catcher disposed at the selected location. With the optical fiber cable in the well, a portion of the optical fiber cable can be coupled to surface instrumentation. Additional apparatus, systems, and methods can be implemented in a variety of applications.

A system may include a splice housing positioned along a portion of tubing in a wellbore and a splice housing protector around the splice housing. An uphole fiber optic cable may extend through the splice housing protector. The uphole fiber optic cable may mate with a first port of the splice housing at a downhole end of the splice housing protector. A downhole fiber optic cable may mate with a second port of the splice housing in the splice housing protector. The splice housing may splice the uphole fiber optic cable and the downhole fiber optic cable.

The optical unit includes an optical fiber and a ferrule, and the ferrule is sleeved on the optical fiber. The electrical unit includes a wire and a wire jacket, and the wire jacket is sleeved on the wire. The outer jacket wraps outside the optical unit and the electrical unit, and the optical unit and the electrical unit are disposed closely adjacent to each other. An extension direction of the optical unit is consistent with an extension direction of the electrical unit, and at least one convex structure is disposed on an outer wall of the outer jacket.

The present invention discloses a logging encapsulated optical-fiber duct cable and a manufacturing method thereof. The encapsulated optical-fiber duct cable mainly comprises an external encapsulation layer. At least one armor tube is arranged in the encapsulation layer. An optical fiber protective tube is arranged in each armor tube. A filling layer is arranged in a space between the optical fiber protective tube and the armor tube. An optical fiber is arranged in the optical fiber protective tube. The manufacturing method mainly comprises four steps: pavement of the optical fiber and formation of the protective tube, formation of the filling layer, formation of the armor tube and formation of the encapsulation layer. The optical-fiber duct cable of the present invention has the advantages of large length, high strength, good temperature tolerance, small signal transmission loss, high transmission speed and synchronous transmission of multiple signals.

A submarine device includes a main tail cable connected to a submarine cable, a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable, a second branch tail cable including a second group of optical fibers among the plurality of optical fibers, a branch member that couples the main tail cable to the first and second branch tail cables and including therein a through hole for branching the plurality of optical fibers included in the main tail cable into the first group and the second group, and a device main body including a first introduction part for introducing the first branch tail cable into the device main body and a second introduction part for introducing the second branch tail cable into the device main body. The branch member is fixed to the device main body.

Pipeline segments can contain cables, such as communication cables (e.g., fiber optic cables) within insulation material surrounding the pipeline segments. Cables can be embedded within the insulation material, run through conduits embedded within the insulation material, placed in channels formed in the insulation material, or otherwise. Channels containing one or more cables can be filled with supplemental insulation material, thus securing the cables within the channels. Pipelines created as disclosed herein can enable data transfer between distant points without the need to lay fiber optic cable in addition to the pipeline. Further, fiber optic cable embedded thusly can be used to sense conditions in the pipeline, such as leaks, seismic activity, strain, and temperature information.
