Description

Technical Field

[0001] This application relates to the field of logging cable technology, and in particular to a packaged cable. Background Technology

[0002] Logging cables can be used for logging, perforation, and coring operations in various oil and gas fields, as well as in hydraulic and hydrological surveying, coalfield geological exploration, and geothermal logging. They serve as load-bearing connections and data transmission lines between surface systems and underground instruments. Existing encapsulated cables have an encapsulation layer that protects the internal pipes and cables. However, when connecting to equipment, a portion of the encapsulation layer needs to be peeled off. Finding a quick, safe, and economical way to peel off this layer has become a major challenge.

[0003] In related technologies, two methods are generally used for peeling: direct peeling with a knife and peeling with a tear rope. Direct peeling with a knife carries the risk of scratching the pipe and injuring people. Peeling with a tear rope requires designing a U-shaped groove in the pipe's encapsulation layer, with the tear rope pre-embedded inside. However, the tear rope reduces the thickness of the encapsulation layer, easily causing the thinnest point of the encapsulation layer to fail, thus weakening its functional strength. Utility Model Content

[0004] This application provides a packaged cable to solve the technical problem that the use of tear cord in existing packaged cables reduces the thickness of the packaged layer, easily causing the thinnest point of the packaged layer to fail and weakening the functional strength of the packaged layer.

[0005] In a first aspect, this application provides a packaged cable, comprising:

[0006] Protective tube;

[0007] An encapsulation layer is fitted onto the outer periphery of the protective tube;

[0008] A packaging strip is embedded in the packaging layer. The packaging strip includes a first side and a second side disposed opposite to each other. The first side of the packaging strip is at least partially attached to the outer surface of the protective tube, or the first side of the packaging strip has at least a gap with the outer surface of the protective tube. The second side of the packaging strip is flush with the outer side of the packaging layer, or the second side of the packaging strip protrudes relative to the outer side of the packaging layer.

[0009] In one possible implementation, the encapsulation layer extends along the axial direction of the protective tube, the encapsulation layer has a first end and a second end disposed opposite to each other, and the encapsulation strip extends from the first end of the encapsulation layer to the second end of the encapsulation layer.

[0010] In one possible implementation, the length direction of the encapsulation strip is parallel to the axial direction of the protective tube.

[0011] In one possible implementation, the encapsulation strip is arranged in a spiral coil around the axis of the protective tube.

[0012] In one possible implementation, the encapsulation strip is provided with reinforcing ribs.

[0013] In one possible implementation, multiple encapsulation strips are provided, and when the cross-section of the outer side of the encapsulation layer is square, at least two of the encapsulation strips are respectively provided on adjacent sides of the encapsulation layer;

[0014] And / or,

[0015] At least two of the encapsulation strips are respectively disposed on opposite sides of the encapsulation layer.

[0016] In one possible implementation, the encapsulation layer includes a first encapsulation portion and a second encapsulation portion, wherein the first encapsulation portion is sleeved on the outer peripheral side of the protective tube, and the second encapsulation portion is sleeved on the outer peripheral side of the first encapsulation portion;

[0017] The encapsulation strip includes a first encapsulation body and a second encapsulation body. The first encapsulation body is embedded in the first encapsulation part, and the second encapsulation body is embedded in the second encapsulation part. The first encapsulation body and the second encapsulation body are stacked in the radial direction of the protective tube.

[0018] In one possible implementation, the encapsulation strip is provided with a protrusion that protrudes from the first end or the second end of the encapsulation layer.

[0019] In one possible implementation, multiple protective tubes are provided, and the multiple protective tubes are spaced apart along the width direction of the encapsulation layer. Multiple encapsulation strips are provided, and each of the multiple encapsulation strips corresponds to one of the protective tubes.

[0020] In one possible implementation, the multiple encapsulation strips are configured with different colors depending on the function of the protective tube.

[0021] In one possible implementation, the protective tube is at least one of the following: a cable protection tube, an oil tube.

[0022] The technical solutions provided in this application have the following advantages compared with the prior art:

[0023] The encapsulated cable provided in this embodiment, when in use, cuts the encapsulation layer wrapped around the protective tube by stretching the encapsulation strip outward, exposing the inner protective tube and facilitating connection of the protective tube to equipment in the mine or on the surface. Since the first side of the encapsulation strip connects to the protective tube, and the second side extends radially towards the protective tube and connects to the outer side of the encapsulation layer, the encapsulation strip can provide significant shearing force, causing the encapsulation layer to tear from the inside out, preventing local adhesion and reducing labor intensity for workers. Compared to existing technologies, the encapsulated cable provided in this embodiment does not require slotting in the encapsulation layer, thus not reducing the thickness of the encapsulation layer. The encapsulation layer and encapsulation strip can be fused together, ensuring the functional strength of the encapsulation layer and preventing damage to the protective tube due to external forces. Simultaneously, it avoids scratching the tube groove by peeling the encapsulation layer with a knife and improves the safety of the peeling process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0038] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0039] In related technologies, two methods are generally used for peeling: direct peeling with a knife and peeling with a tear rope. Direct peeling with a knife carries the risk of scratching the pipe and injuring people. Peeling with a tear rope requires designing a U-shaped groove in the pipe's encapsulation layer, with the tear rope pre-embedded inside. However, the tear rope reduces the thickness of the encapsulation layer, easily causing the thinnest point of the encapsulation layer to fail, thus weakening its functional strength.

[0040] To address the technical problem that the use of tear cords in existing encapsulation cables reduces the thickness of the encapsulation layer, easily causing the thinnest point of the encapsulation layer to fail and weakening the functional strength of the encapsulation layer, this application provides an encapsulation cable that can ensure the functional strength of the encapsulation layer and prevent the protective tube from being damaged by external forces.

[0041] Figure 1 and Figure 2 The present application provides a packaged cable including a protective tube 1, a packaged layer 2, and a packaged strip 3. The packaged layer 2 is sleeved on the outer periphery of the protective tube 1. The packaged strip 3 is embedded in the packaged layer 2 and includes a first side 31 and a second side 32 disposed opposite to each other. The first side 31 of the packaged strip 3 is at least partially attached to the outer surface of the protective tube 1, or the first side 31 of the packaged strip 3 has at least a gap with the outer surface of the protective tube 1. The second side 32 of the packaged strip 3 is flush with the outer side of the packaged layer 2, or the second side 32 of the packaged strip 3 protrudes relative to the outer side of the packaged layer 2.

[0042] It should be noted that the inner and outer sides of the encapsulation layer 2 are relative to the protective tube 1. The inner side of the encapsulation layer 2 refers to the inner surface of the encapsulation layer 2 that contacts the protective tube 1, and the outer side of the encapsulation layer 2 refers to the outer surface of the encapsulation layer 2 that is away from the protective tube 1. The radial direction of the protective tube 1 can be the Z-direction shown in the figure, and the axial direction of the protective tube can be the X-direction shown in the figure. The first side 31 of the encapsulation strip 3 is at least partially attached to the outer surface of the protective tube 1, or the first side 31 of the encapsulation strip 3 has at least a gap with the outer surface of the protective tube 1. That is to say, the second side 32 of the encapsulation strip 3 extends radially towards the protective tube 1. The second side 32 of the encapsulation strip 3 is flush with the outer side of the encapsulation layer 2, or the second side 32 of the encapsulation strip 3 protrudes relative to the outer side of the encapsulation layer 2, so that the encapsulation strip 3 has a certain thickness in the radial direction of the protective tube 1. This can ensure the overall functional strength of the encapsulation layer 2, and at the same time, the encapsulation strip 3 has a certain tear resistance. Understandably, during use, by stretching the sealing strip 3 outward, the sealing strip 3 cuts the sealing layer 2 wrapped around the protective tube 1, exposing the inner protective tube 1, making it convenient for workers to connect the protective tube 1 to equipment in the mine or on the surface. Because the sealing strip 3 has a certain thickness, it can provide significant shearing force, causing the sealing layer 2 to tear from the inside out, preventing local adhesion of the sealing layer 2 and reducing the workload for workers. Compared to existing technologies, the sealing cable provided in this embodiment does not require slotting in the sealing layer 2, thus not reducing the thickness of the sealing layer 2. The sealing layer 2 and the sealing strip 3 can be fused together, ensuring the functional strength of the sealing layer 2 and preventing damage to the protective tube 1 due to external forces. Simultaneously, it avoids scratching the protective tube 1 when peeling off the sealing layer 2 with a knife, and improves the safety of the peeling process.

[0043] In some embodiments, the cross-section of the outer side of the encapsulation layer 2 can be polygonal or circular, and the minimum thickness of the encapsulation layer 2 is greater than or equal to 2 mm. In one example, such as... Figure 3 As shown, the cross-section of the outer side of the encapsulation layer 2 is circular, and the thickness of the encapsulation layer 2 is uniformly set, with a thickness greater than or equal to 2 mm; in one example, such as Figure 2 As shown, the outer cross-section of the encapsulation layer 2 is square. Since the cross-section of the protective tube 1 is circular, the thickness of the encapsulation layer 2 will change along the axial direction of the protective tube 1. That is, the encapsulation layer 2 has a minimum thickness in the radial direction of the protective tube 1, and the minimum thickness is greater than or equal to 2mm. This setting can ensure the functional strength of the encapsulation layer 2 and avoid the thinnest point of the encapsulation layer 2 being unqualified.

[0044] In an embodiment not shown in the figure, a groove or opening is provided at the connection between the encapsulation strip 3 and the encapsulation layer 2. When the encapsulation strip 3 is stretched outward, stress concentration occurs at this point due to the groove or opening, making it easier to tear the encapsulation layer 2. In this embodiment, the encapsulation layer 2 can be made of a thermoplastic material, and the encapsulation strip 3 is also made of the same thermoplastic material as the encapsulation layer 2. That is, the encapsulation strip 3 does not need to be provided with reinforcing ribs, and the encapsulation layer 2 can be torn apart by utilizing the stress concentration at the groove or opening.

[0045] In one embodiment, such as Figure 1 As shown, the encapsulation layer 2 extends along the axial direction of the protective tube 1. The encapsulation layer 2 has a first end 201 and a second end 202 disposed opposite to each other. The encapsulation strip 3 extends from the first end 201 to the second end 202 of the encapsulation layer 2. It can be understood that the encapsulation layer 2, extending along the axial direction of the protective tube 1, can effectively protect the protective tube 1 and improve its corrosion resistance. The protective tube 1 has a high yield load, improving its overall compressive and tensile strength. The encapsulation layer 2 has a first end 201 and a second end 202 disposed opposite to each other. The encapsulation strip 3 extends from the first end 201 to the second end 202 of the encapsulation layer 2. That is, by stretching the encapsulation strip 3 outward, the encapsulation strip 3 can continuously provide shear force to the encapsulation layer 2, causing the encapsulation layer 2 to tear under the action of this shear force.

[0046] In one embodiment, such as Figure 1 As shown, the length direction of the encapsulation strip 3 is parallel to the axial direction of the protective tube 1. Regardless of whether the outer cross-section of the encapsulation layer 2 is polygonal or circular, the length direction of the encapsulation strip 3 can remain parallel to the axial direction of the protective tube 1. Stretching the encapsulation strip 3 outwards allows it to cut through the encapsulation layer 2 along its own length, exposing the inner protective tube 1 and facilitating connection of the protective tube 1 to equipment in the mine or on the surface. When the outer cross-section of the encapsulation layer 2 is polygonal, the encapsulation strip 3 is embedded at the thinnest point of the encapsulation layer 2. This arrangement, with the encapsulation strip 3 located at the thinnest point of the encapsulation layer 2, facilitates the peeling of the encapsulation layer 2 by workers.

[0047] In one embodiment, such as Figure 4 As shown, the encapsulation strip 3 is spirally coiled around the axis of the protective tube 1. In this embodiment, the outer cross-section of the encapsulation layer 2 is circular, and the encapsulation strip 3 is spirally coiled around the axis of the protective tube 1. By stretching the encapsulation strip 3 outward, the encapsulation strip 3 can cut the encapsulation layer 2 along its own length. Due to the spiral winding arrangement of the encapsulation strip 3, the encapsulation layer 2 is easier to peel off, exposing the inner protective tube 1, which facilitates the connection of the protective tube 1 to equipment in the mine or on the surface.

[0048] In some embodiments, reinforcing ribs are provided within the encapsulation strip. For example, the length direction of the encapsulation strip 3 is parallel to the axial direction of the protective tube 1, and the reinforcing ribs can extend along the axial direction of the protective tube 1; the encapsulation strip 3 is spirally coiled around the axis of the protective tube 1, and the reinforcing ribs can extend spirally along the circumferential direction of the protective tube 1. By providing reinforcing ribs, the tear resistance of the encapsulation strip can be improved.

[0049] For example, the encapsulation layer 2 can be made of thermoplastic materials, such as TPV, PP, FEP or PVDF. The encapsulation strip 3 can be a plastic synthetic strip made of a substrate and reinforcing ribs. The substrate is made of the same thermoplastic material as the encapsulation layer 2, and the reinforcing ribs are made of polyaramid synthetic fiber, Kevlar fiber or metal wire, so that the encapsulation strip 3 has strong tear resistance on the one hand, and can ensure the fusion of the encapsulation layer 2 and the encapsulation strip 3 on the other hand.

[0050] In some embodiments, multiple sealing strips 3 are provided. When the cross-section of the outer side of the sealing layer 2 is polygonal, at least two sealing strips 3 are respectively provided on adjacent sides of the sealing layer 2. It is understood that by providing multiple sealing strips 3, the operator can pull outwards multiple sealing strips 3 respectively, and the multiple sealing strips 3 can cut the sealing layer 2 wrapped on the protective tube 1, avoiding local adhesion of the sealing layer 2, and the sealing layer 2 can be completely peeled off, thereby saving the operator's labor intensity.

[0051] In a preferred embodiment, such as Figure 5 As shown, multiple encapsulation strips 3 are provided. When the cross-section of the outer side of the encapsulation layer 2 is set as a polygon, two encapsulation strips 3 are respectively set on opposite sides of the encapsulation layer 2. It can be understood that, since at least two encapsulation strips 3 are respectively set on opposite sides of the encapsulation layer 2, and the two encapsulation strips 3 are stretched outward at the same time, the opposite sides of the encapsulation layer 2 are respectively subjected to a cutting force in the radial direction of the cable 4 away from the cable 4, making it easier to completely peel off the encapsulation strips 3.

[0052] Of course, multiple encapsulation strips 3 can also be simultaneously placed on adjacent sides of the encapsulation layer 2, as well as on opposite sides of the encapsulation layer 2.

[0053] In one embodiment, such as Figure 1 As shown, the encapsulation strip 3 is provided with a protrusion 33, which protrudes from the first end 201 or the second end 202 of the encapsulation layer 2. It can be understood that by providing the protrusion 33, it is convenient for the operator to apply external force, pinch the protrusion 33 and pull the encapsulation strip 3 outward. The encapsulation strip 3 cuts the encapsulation layer 2 wrapped on the protective tube 1, so that the inner protective tube 1 is exposed, making it convenient for the operator to connect the protective tube 1 to equipment in the mine or on the surface.

[0054] For example, the protrusion 33 can be shaped as a cuboid, a cone, or a wedge. The protrusion 33 can extend along the axial direction of the protective tube 1 or along the radial direction of the protective tube 1. Of course, the protrusion 33 can extend along other directions, and this application does not impose any specific limitations on this.

[0055] In one embodiment, such as Figure 1 As shown, multiple protective tubes 1 are provided, spaced apart along the width direction of the encapsulation layer 2. Multiple encapsulation strips 3 are also provided, each corresponding to one of the protective tubes 1. For ease of explanation and understanding, the width direction of the encapsulation layer 2 can be the Y-direction shown in the figure. The cross-section of the outer side of the encapsulation layer 2 can be polygonal. Multiple encapsulation strips 3 correspond one-to-one with the protective tubes 1 and are positioned at the minimum thickness of the encapsulation layer 2. Workers can sequentially stretch the multiple encapsulation strips 3 outwards, allowing each strip to cut along its own length direction, thus exposing the multiple protective tubes 1 sequentially. This facilitates the connection of the protective tubes 1 to equipment in the mine or on the surface.

[0056] In one embodiment, multiple encapsulation strips 3 are configured with different colors according to the different functions of the protective tubes 1. In this embodiment, the different colors of the protective tubes within the encapsulation cable are used to identify the different functions of each protective tube. For example, if the function of the protective tube is to run cables or optical fibers inside to transmit electrical energy or communication signals, then the encapsulation strip corresponding to that protective tube can be marked blue; if the function of the protective tube is to inject chemical agents, then the encapsulation strip corresponding to that protective tube can be marked green; if the function of the protective tube is to circulate lubricating oil or cleaning agents to lubricate or clean the equipment, then the encapsulation strip corresponding to that protective tube can be marked red. This arrangement allows for the identification of the protective tube 1 when it is connected to equipment in the mine or on the surface, facilitating on-site construction.

[0057] In one embodiment, such as Figure 6As shown, the encapsulation layer 2 includes a first encapsulation part 21 and a second encapsulation part 22. The first encapsulation part 21 is sleeved on the outer periphery of the protective tube 1, and the second encapsulation part 22 is sleeved on the outer periphery of the first encapsulation part 21. The encapsulation strip 3 includes a first encapsulation body 34 and a second encapsulation body 35. The first encapsulation body 34 is embedded on the first encapsulation part 21, and the second encapsulation body 35 is embedded on the second encapsulation part 22. The first encapsulation body 34 and the second encapsulation body 35 are stacked in the radial direction of the protective tube 1. The first encapsulation body 34 and the second encapsulation body 35 are stacked in the radial direction of the protective tube 1. This arrangement is suitable for encapsulated cables with special requirements. For example, a single protective tube 1 of the encapsulated cable is covered with a separate first encapsulation part 21. The first encapsulation body 34 is used to tear the first encapsulation part 21. Several other protective tubes 1 are then combined to cover another layer of overall encapsulation layer 2, namely the second encapsulation part 22. The second encapsulation body 35 is used to tear the outer overall second encapsulation part 22. In use, the second encapsulation body 35 can be stretched first to peel off the second encapsulation part 22, and then the first encapsulation body 34 can be stretched to peel off the first encapsulation part 21.

[0058] In one embodiment, such as Figure 7 As shown, a cable 4 is installed inside the protective tube. The cable 4 includes a conductor 41, an insulation layer 42, and a filler layer 43, arranged sequentially from the inside to the outside. The cable 4 is used to connect downhole instruments and equipment to transmit signals. In this embodiment, the filler layer 43 is made of polypropylene (PP) material. The insulation layer 42 is made of fluorinated ethylene propylene copolymer (FEP) material. The filler layer 43 provides insulation, flame retardancy, corrosion protection, and fixation for the encapsulated material. The cable 4 is produced by a cable extrusion machine, which is a conventional technical method and will not be described in detail here.
