Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pipe cable, especially to a square section packaging pipe cable. BACKGROUND

[0002] The packaging logging pipe cable can be used for logging, perforating, coring and other operations of various oil and gas wells, and can also be used for water conservancy and hydrology measurement, oilfield geological exploration, geothermal logging and other aspects, and is a connecting line for bearing connection and transmission of measurement data between the ground system and underground instruments. The existing packaging logging pipe cable mainly comprises an external packaging protective layer and an internal pipeline. The packaging logging pipe cable needs to peel off the packaging layer at the end during use, so as to expose the internal pipeline. The packaging pipe cable at the present stage can realize the peeling function of the pipe cable packaging layer by setting a tearing rope inside the packaging layer. However, due to the large thickness of the packaging layer, the resistance of the packaging layer is large when the tearing rope is pulled, and the wire rope is prone to breakage. In addition, in the prior art, tools such as knives and clamps can also be used to break the packaging layer. However, when cutting the packaging layer, the knife is easy to directly contact the inner tube, causing damage to the inner tube. SUMMARY

[0003] The utility model aims at providing a square section packaging pipe cable to solve the technical problems mentioned in the background.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme:

[0005] The utility model relates to a square section packaging pipe cable, which comprises a pipeline, a first packaging layer is arranged outside the pipeline, two tearing lines are symmetrically arranged inside the first packaging layer, a foamed filling layer is arranged outside the first packaging layer, a second packaging layer is arranged outside the foamed filling layer, the outer peripheral wall cross section profile of the second packaging layer is square, and a plurality of breaking slots are uniformly arranged on the peripheral wall.

[0006] Further, the number of the plurality of breaking slots is three, and each is arranged at the middle part of the adjacent three outer walls of the second packaging layer.

[0007] Further, the first packaging layer is provided with a color identification band at the part opposite to the side of the second packaging layer where no breaking slot is arranged.

[0008] Further, an inner groove is arranged in the middle of each of the adjacent two breaking slots of the inner wall of the second packaging layer.

[0009] Further, two foamed protrusions respectively matched with each of the inner grooves are symmetrically arranged on the outer wall of the foamed filling layer.

[0010] Furthermore, the two tear lines are symmetrically arranged along the color identification tape.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] When peeling off the encapsulation layer of the encapsulated pipe and cable, the jaws of the nutcracker can be positioned between two adjacent rupture grooves, and the nutcracker jaws can be used to apply force inward to cut off the weak point of the encapsulation between the rupture grooves, so that the second encapsulation layer between the two rupture grooves is lifted up in a strip shape, and the lifted strip of the first encapsulation layer can be pulled off along the axial direction of the pipeline. In the process of peeling off the second encapsulation layer, the presence of the foam filling layer and the first encapsulation layer can protect the internal pipeline and avoid damage to the pipeline when the tool cuts the encapsulation layer. After the second encapsulation layer is peeled off, the first encapsulation layer can be easily peeled off from the pipeline by pulling the tear line. Since the thickness of the internal first encapsulation layer is relatively thin, the resistance of the encapsulation layer to the tear rope during the pulling process is reduced, thereby avoiding the occurrence of the tear rope breaking.

[0017] like Figs. 1-2 As shown, a square-cross-section encapsulated tube cable includes an internal pipeline 1. A first encapsulation layer 2 is provided on the outside of the pipeline 1. Two tear lines 3 are symmetrically arranged inside the first encapsulation layer 2. A foam filling layer 4 is provided on the outside of the first encapsulation layer 1. A second encapsulation layer 5 is provided on the outside of the foam filling layer 4. The outer cross-sectional profile of the outer peripheral wall of the second encapsulation layer 5 is square, and multiple tear grooves 6 are evenly distributed on the peripheral wall.

[0018] The material of the first encapsulation layer and the second encapsulation layer is specifically polyvinylidene fluoride (PVDF), polypropylene (PP), polyamide (PA), thermoplastic elastomer (TPE, TPU, TPR), thermoplastic vulcanized rubber (TPV), ethylene-tetrafluoroethylene copolymer (ETFE), polyperfluoroalkyl alkoxy (FEP), ethylene chlorotrifluoroethylene copolymer (ECTFE), or polytetrafluoroethylene (PFA) and the like thermoplastic materials.

[0019] In the embodiment, the number of the plurality of breaking slots 6 is three, and each is arranged at the middle part of the adjacent three outer walls of the second encapsulation layer 5. In addition, the first encapsulation layer 2 is provided with a color identification band 7 at the part opposite to the side of the second encapsulation layer 5 where no breaking slot 6 is arranged, and the two tearing lines 3 on the first encapsulation layer 2 are symmetrically arranged along the color identification band 7.

[0020] When the encapsulation layer of the encapsulated cable is peeled off, the jaws of the nutcracker can be positioned between two adjacent breaking slots, and the nutcracker jaws are forced inward to cut the weak point of the encapsulation at the position between the breaking slots, so that the second encapsulation layer between the two breaking slots is raised in a strip shape, and the raised strip-shaped first encapsulation layer can be peeled off by pulling it along the pipeline axis. In the process of peeling off the second encapsulation layer, the foamed filling layer and the first encapsulation layer can protect the internal pipeline, avoiding damage to the pipeline when the tool cuts off the encapsulation layer. After the second encapsulation layer is peeled off, the first encapsulation layer can be easily peeled off from the pipeline by pulling the tearing line. Since the thickness of the internal first encapsulation layer is relatively thin, the resistance of the tearing rope to the encapsulation layer during the pulling process is reduced, and the tearing rope is prevented from breaking.

[0021] As a further improvement of the utility model, the inner wall of the second encapsulation layer 5 is provided with an inner groove 8 in the middle of each adjacent two breaking slots 6. The inner groove between the two adjacent breaking slots can make the encapsulation part between the breaking slots more easily cut off. The outer wall of the foamed filling layer 4 is symmetrically provided with two foamed protrusions 9 respectively matched with each inner groove 8, so as to fill the inner groove and ensure the sealing performance.

[0022] The above-described embodiments are only preferred modes of the utility model, and do not limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements of the technical solutions of the utility model made by those skilled in the art shall fall within the protection scope determined by the claims of the utility model.
