Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil extraction downhole, in particular to a cable traverser and a cable connector. BACKGROUND

[0002] The cable traverser downhole is a special device for the downhole environment of oil wells, gas wells and the like. Its main function is to realize a safe and reliable connection mode when the cable traverses the packer downhole, so that the cable can smoothly extend from the upper end to the lower end of the packer, while ensuring the sealing, insulation and integrity of the cable in the well.

[0003] In the related art, different well depths and well pressures (such as 35 MPa, 70 MPa and different well pressures) have completely different requirements for sealing levels. The traverser with fixed sealing strength cannot flexibly cope with such changes. The traverser designed to meet the highest pressure working conditions will cause structural redundancy and cost waste when used in low pressure wells; conversely, the traverser designed to meet low pressure working conditions has a huge risk of sealing failure when used in high pressure wells.

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0037] For ease of description and understanding, the direction of cable extension is defined as the axial direction, and the direction perpendicular to the axial direction is defined as the radial direction. The direction radially away from the cable axis is defined as the outward direction. The technology of this application will be further described below in conjunction with the accompanying drawings.

[0038] Figure 1 This is a structural schematic diagram of an embodiment of the cable connector of the present invention. Figure 2 This is a connection diagram of the cable runner 10 of the present invention.

[0039] See Figure 1 and Figure 2 The embodiments of this application provide a cable connector, which includes a junction box 20 and a plurality of cable runners 10, each cable runner 10 being connected to a single-phase cable, thereby enabling the transmission of multiple single-phase cables to the junction box 20.

[0040] The cable runner 10 includes a first connecting unit 100 and a second connecting unit 200, which are used to secure cables respectively. For example, the first connecting unit 100 is used to thread and secure a first cable 910; the second connecting unit 200 is used to thread and secure a second cable 920. The second connecting unit 200 and the first connector 110 are axially opposite to each other, such that the second cable 920 in the second connecting unit 200 and the first cable 910 in the first connector 110 are connected.

[0041] Figure 3 This is a schematic diagram of the structure of an embodiment of the first connecting unit 100 of the present invention.

[0042] See Figures 1 to 3 The first connecting unit 100 includes a first connector 110 and a sealing assembly 300. The first connector 110 is used to be sleeved on the outer periphery of the first cable 910, and an installation space 120 is formed between the outer periphery of the first cable 910 and the inner side of the first connector 110; the sealing assembly 300 is disposed in the installation space 120, and the sealing assembly 300 is radially sealed and fitted to the inner side of the first connector 110 and the outer side of the first cable 910 respectively; the installation space 120 can be axially provided with one or more sealing assemblies 300.

[0043] One or more sealing components 300 can be flexibly configured axially within the installation space 120 of the first connecting unit 100, so that the sealing structure can be adaptively adjusted according to the actual well depth and well pressure requirements. This avoids the risk of failure due to insufficient sealing under high pressure conditions, and overcomes the structural redundancy and cost waste caused by fixed sealing schemes in low pressure applications, thereby achieving efficient and economical adaptation to downhole environments of different pressure levels.

[0044] Figure 4 This is a structural schematic diagram of an embodiment of the sealing unit 310 of this application. Figure 5 This is a schematic diagram of the sealing ring 311 of this application.

[0045] SeeFigure 4 and Figure 5 The sealing assembly 300 includes one or more sealing units 310, each including a sealing ring 311, an inner sealing ring 312, and an outer sealing ring 313. The sealing ring 311, inner sealing ring 312, and outer sealing ring 313 are all annular structures. The inner sealing ring 312 is radially clamped between the outer side of the first cable 910 and the inner side of the sealing ring 311; the outer sealing ring 313 is radially clamped between the outer side of the sealing ring 311 and the inner side of the first connector 110. The inner and outer sealing rings 313 provide sealing between the first cable 910 and the first connector 110. The inner sealing ring 312 and outer sealing ring 313 are both annular structures and are capable of elastic deformation.

[0046] In one example, an inner annular groove 3111 is formed on the inner side of the sealing ring 311. The inner annular groove 3111 is open on the side facing the second connecting unit 200 to facilitate the placement of the inner sealing ring 312 into the inner annular groove 3111 from the open side. The inner sealing ring 312 is respectively sealed and fitted to the outer periphery of the first cable 910 and the peripheral sidewall of the inner annular groove 3111 on both radial sides to seal between the outer periphery of the first cable 910 and the peripheral sidewall of the inner annular groove 3111.

[0047] In one embodiment, the peripheral sidewall of the inner annular groove 3111 gradually increases in diameter in the direction toward the second connecting unit 200 to form a sealing slope 3112. The inner annular groove 3111 is inclined outwards from the axis opposite to the first connector 110 in the direction toward the second connecting unit 200. The inner sealing ring 312 is capable of elastic deformation; its inner surface adheres to the outer periphery of the first cable 910, and its outer surface adheres to the sealing slope 3112. By adjusting the position of the inner sealing ring 312 relative to the sealing slope 3112 in the axial direction, the sealing pressure of the inner sealing ring 312 can be adjusted, thereby adjusting the sealing performance.

[0048] In one example, the inner sealing ring 312 directly or indirectly abuts against the second connecting unit 200 on the side facing the second connecting unit 200. The abutment of the inner sealing ring 312 by the second connecting unit 200 can maintain the position of the inner sealing ring 312, maintain the inner sealing ring 312, and maintain the seal between the inner sealing ring 312 and the sealing slope 3112.

[0049] The second connecting unit 200 can be fixed at different positions axially relative to the first connector 110, thereby driving the inner sealing ring 312 to be adjusted to different positions axially relative to the sealing slope 3112, and pushing the inner sealing ring 312 to move. The second connecting unit 200 can move axially relative to the first connecting unit 100 and be fixed at different positions axially. By sliding the second connecting unit 200 relative to the first connecting unit 100 axially, the inner sealing ring 312 is pushed to move axially, and the inner sealing ring 312 can fit against the sealing slope 3112 at different positions, thereby adjusting the sealing clamping force.

[0050] In other examples, a serrated structure is formed within the sealing bevel 3112. This serrated structure is inclined away from the second connecting unit 200 in the direction towards the first cable 910, thereby enhancing the force between the inner sealing ring 312 and the sealing bevel 3112 and effectively maintaining the position of the inner sealing ring 312 on the sealing bevel 3112. The serrations are annular to improve the sealing performance between the sealing bevel 3112 and the inner sealing ring 312.

[0051] In some embodiments, the side of the inner sealing ring 312 facing the sealing slope 3112 is an adapting slope that is adapted to the sealing slope 3112, and the adapting slope is parallel to and fits the sealing slope 3112.

[0052] In one embodiment, multiple sealing units 310 are provided, and the arrangement of multiple sealing units 310 enhances the sealing effect. Between adjacent sealing units 310, the inner sealing ring 312 abuts against the corresponding sealing ring 311 on the side facing the second connecting unit 200.

[0053] In one example, between two adjacent sealing units 310, the end of the sealing ring 311 abutting against the corresponding inner sealing ring can extend into the inner ring groove 3111 of the corresponding sealing ring, thereby making the structure more compact in the axial direction, and thus enabling more sealing components to be installed in the axial direction.

[0054] An outer annular groove 3113 is provided on the outer side of the sealing ring 311. The outer annular groove 3113 is used to accommodate the outer sealing ring 313, so that the outer sealing ring 313 is radially clamped between the inner side of the first joint 110 and the outer sealing ring 313. One or more outer sealing rings 313 are provided on each sealing ring 311 along the axial direction.

[0055] In one example, the sealing ring 311 includes abutting section 3114 and sealing section 3115; inner sealing ring 312 and outer sealing ring 313 are respectively disposed on the inner and outer sides of sealing section 3115. Abutting section 3114 protrudes from the side of sealing section 3115 facing away from the second connecting unit 200. Between two adjacent sealing rings 311, the end of abutting section 3114 facing the inner sealing ring 312 can extend into the groove of sealing ring 311 to abut against the inner sealing ring 312 in the groove of sealing ring 311.

[0056] The sealing ring 311 can slide axially to different positions within the sealed space. For example, a sliding plane 111 is formed on the inner side of the first connector 110, and the sliding plane 111 is parallel to the axial direction; the opposing sides of the abutment section 3114 and the sealing section 3115 are parallel to the axial direction, respectively. The side of the sealing section 3115 facing away from the first cable 910 is attached to the sliding plane 111. The side of the abutment section 3114 facing away from the first connector 110 is attached to the first cable 910. This allows the sealing ring 311 to slide axially, thereby generating different magnitudes of compressive force on the inner sealing ring 312 on the sealing ring 311, thus adjusting the magnitude of the sealing force.

[0057] See Figure 3 and Figure 4 The sealing assembly 300 further includes a first sealing ring 320; the first sealing ring 320 is sleeved on the outside of the first cable 910; the first sealing ring 320 is radially clamped between the outer side of the first cable 910 and the inner side of the first connector 110 to seal between the outer side of the first cable 910 and the inner side of the first connector 110. Through the arrangement of the sealing assembly 300 and the first sealing ring 311, a multiple sealing structure is formed radially.

[0058] The first sealing ring 320 abuts against the sealing ring 311 on the side facing the second connecting unit 200, thereby effectively restricting the movement of the first sealing ring 311 axially toward the second connector 210, so as to maintain the position of the first sealing ring 320.

[0059] In some embodiments, the inner side of the first connector 110 is provided with an inclined, close-fitting slope 112; the inner diameter of the close-fitting slope 112 gradually increases in the axial direction toward the second connecting unit 200; the first sealing ring 320 is capable of elastic deformation, the inner side of the first sealing ring 320 is in contact with the outer periphery of the first cable 910, the outer side of the first sealing ring 320 is in contact with the first sealing slope 3112, and the side of the first sealing ring 320 facing the second connecting unit 200 abuts against the sealing ring 311. By adjusting the abutting force of the sealing ring 311 against the first sealing ring 320, the pressure of the first sealing ring 320 between the first connector 110 and the first cable 910 can be adjusted.

[0060] In one example, the end of the sealing ring 311 abutting against the first sealing ring 320, facing away from the second connecting unit, can extend into the enclosure of the inclined surface 112. That is, the radial projection of the end of the sealing ring 311 abutting against the first sealing ring 320, facing away from the second connecting unit, coincides with the inclined surface 112. This abuts against the first sealing ring 320 within the enclosure of the inclined surface 112, thereby adjusting the position and sealing pressure of the first sealing ring 320. Simultaneously, the end of the sealing ring 311 facing away from the second connecting unit can extend into the enclosure of the inclined surface 112, making the structure more compact in the axial direction, thus allowing for more layers of sealing components to be arranged axially.

[0061] See Figure 3 The sealing assembly 300 also includes a second sealing ring 330; the second sealing ring 330 is disposed at one end of the first connector 110 facing away from the second connecting unit 200; the second sealing ring 330 is sealed between the inner side of the first connector 110 and the outer side of the first cable 910 to form a sealing structure between the inner side of the first connector 110 and the first cable 910.

[0062] In some embodiments, the sealing assembly 300 further includes a stop ring 340; the stop ring 340 is sleeved on the outside of the first cable 910, and its two ends along the axial direction abut against the sealing unit 310 and the first connecting unit 100, respectively, to limit the sealing unit 310 within the installation space 120. The stop ring 340 is disposed within the installation space 120, and elastic rings for sealing are respectively provided on the inner and outer circumferences of the stop ring 340. Elastic rings are provided on the outer circumference of the stop ring 340 and the inner circumference of the first connector 110; an elastic ring is provided between the inner circumference of the stop ring 340 and the first cable 910.

[0063] In one example, the inner and outer circumferences of the stop ring 340 are respectively provided with limit grooves 341 for installing elastic rings.

[0064] Figure 6 This is a structural schematic diagram of an embodiment of the first fixing component 400 of this application.

[0065] See Figure 3 and Figure 6 The cable passer 10 also includes a first fixing component 400, which includes a fixing ring 410 and a connecting tube 420. The connecting tube 420 is sleeved on the outer periphery of the first cable 910. The fixing ring 410 is sleeved on the outer periphery of the connecting tube 420, and one end of the fixing ring 410 facing the second connecting unit 200 abuts against the second sealing ring 330. The outer side of the end of the fixing ring 410 facing the second connecting unit 200 is threadedly connected to the inner side of the first connector 110. Through the threaded connection, the fixing ring 410 can move axially relative to the first connector 110, thereby adjusting the abutting force on the second sealing head.

[0066] In one example, a guide slope 114 is formed on the inner side of the first connector 110 at the end facing away from the second connecting unit 200. The guide slope 114 is radially outward in the direction facing away from the second connecting unit 200, and the outer side of the second sealing ring 330 is attached to the guide slope 114. The guide slope 114 at the end facing away from the second connecting unit 200 has a flared structure, which facilitates the installation of the second sealing ring 330 inside the guide slope 114. The retaining ring 410, relative to the movable cabinet of the first connector 110 along the axial direction, can also drive the second sealing ring 330 to move along the axial direction to adjust the sealing pressure of the second sealing ring 330.

[0067] In some embodiments, the first fixing component 400 further includes a fixing sleeve 430, which is sleeved on the outer periphery of the connecting tube 420 and located on the side of the fixing ring 410 facing away from the second connecting unit 200. A first receiving cavity 431 is formed at one end of the fixing sleeve 430 facing the first connecting unit 100. The end of the fixing ring 410 facing away from the second connecting unit 200 extends into the first receiving cavity 431 and is threaded onto the side wall of the receiving cavity. The fixing sleeve 430 fixes the fixing ring 410, thus maintaining the fixing sleeve 430 and the fixing ring 410 outside the connecting tube 420.

[0068] In some embodiments, the first fixing assembly 400 further includes a limiting member 440, which is housed within a first receiving cavity 431. One end of the limiting member 440 facing away from the first connecting unit 100 abuts against the sidewall of the receiving cavity. The inner side of the limiting member 440 is attached to the outer periphery of the connecting tube 420. An abutting inclined surface 441 is formed on the outer surface of the limiting member 440. The abutting inclined surface 441 is inclined inwards in the direction towards the first connecting unit 100. One end of the fixing ring 410 facing away from the first connecting unit 100 is attached to the abutting inclined surface 441. By adjusting the positions of the fixing ring 410 and the fixing sleeve 430, the fixing ring 410 can move axially relative to the limiting member 440, thereby adjusting the position of the fixing ring 410 on the abutting inclined surface, controlling the pressure of the limiting member 440 on the connecting tube 420, and stably fixing the connecting tube 420 to the fixing assembly.

[0069] In some embodiments, a mating inclined surface 411 is provided at one end of the fixing ring 410 facing away from the first connecting unit 100; the mating inclined surface 411 is provided on the inner side of the fixing ring 410; the mating inclined surface 411 is inclined outward in the direction facing away from the first connecting unit 100, and the mating inclined surface 411 is used to mate with the abutting inclined surface 441.

[0070] In some embodiments, the connecting pipe 420 is a metal pipe with a predetermined rigidity. One end of the connecting pipe 420 passes through and is connected to the junction box 20, and the other end is connected to the first connecting unit 100 through the first fixing component 400.

[0071] Figure 7 This is a schematic diagram of the structure of an embodiment of the second connecting unit 200 of this application.

[0072] See Figure 2 and Figure 7 The second connection unit 200 includes a second connector 210; the second connector 210 is used to fix and pass through the second cable 920, the second connector 210 and the first connector 110 are arranged opposite each other in the axial direction, and the second connector 210 and the first connector 110 can be connected in the axial direction so that the second cable 920 in the second connector 210 and the first cable 910 in the first connector 110 can be connected; one end of the second connector 210 in the axial direction can extend into the enclosure of the first connector 110 and can be fixedly connected to the first connector 110.

[0073] In some embodiments, a metal elastic frame 220 is provided inside the second connector 210. The two ends of the metal elastic frame 220 can respectively clamp the first cable 910 and the second cable 920, thereby making the first cable 910 and the second cable 920 electrically connected.

[0074] In some embodiments, the second connector 210 can be fixed in different positions along the axial direction relative to the connecting unit, thereby kicking different large compressive forces onto the corresponding sealing assembly 300.

[0075] In one example, the end of the second connector 210 facing the first connecting unit 100 is threaded to the inside of the connecting unit; the end of the second connector 210 facing the first connector 110 directly or indirectly abuts against the sealing unit 310 so as to compress the sealing unit 310.

[0076] In some embodiments, the cable runner 10 further includes a second fixing component 500 and a sleeve 600. The second fixing component 500 is sleeved on the outer periphery of the sleeve 600 and the second cable 920, and is disposed on the side of the second connector 210 facing away from the first connecting unit 100. The second fixing component 500 is sleeved on the outer periphery of the sleeve 600, and one end of the second fixing component 500 facing the second connector 210 is threadedly connected to the second connector 210.

[0077] It should be noted that the first fixing component 400 is sleeved outside the connecting pipe 420 and threaded to the first connector 110. The first fixing component 400 is sleeved outside the sleeve 600 and threaded to the second connector 210. The structure and connection of the second fixing component 500 are the same as those of the first fixing component 400, and will not be described in detail here.

[0078] In one example, both the connecting pipe 420 and the sleeve 600 are rigid tubular structures. One end of the connecting pipe 420 is connected to the junction box 20, and the other end is connected to the first connecting unit 100. One end of the sleeve 600 is connected to the second connecting unit 200 via the second fixing component 500, and the other end of the sleeve 600 is connected to the through-hole and connected to the external structure.
