Description

Technical Field

[0001] The present invention relates to the technical field of detection cables, and in particular to a sealed and anti-corrosion load-bearing detection cable. Background Art

[0002] The load-bearing detection cable is a connecting wire used for hanging weight connection and transmitting measurement data between the ground system and underground instruments, transporting various downhole instruments, transmitting various signals between the ground control system and the downhole instruments, and obtaining the depth position of underground information.

[0003] When used underground, the general operating conditions are relatively harsh. Affected by humidity, gnawing by mosquitoes and corrosion by secretions, etc., corrosion damage occurs. The load-bearing detection cable needs to take good sealing and anti-corrosion measures to prevent water, gas, etc. from entering the inside of the cable body, affecting the transmission function, structural safety and service life. For example, in our company's existing technology (patent application number CN202411766196.5), the inner armor layer with a ring steel structure is combined with the outer armor layer to enhance the structural strength and sealing effect, and the inner armor layer shrinks inward after being stressed to improve the sealing performance. There are also other similar disclosed technologies that strengthen their own sealing performance and structural strength through the inner and outer armor layers, and can resist external impact forces. However, when used downhole, the cable body is easily impacted or rubbed against the well wall, damaging the protection on the surface of the cable body. At the same time, when the inner and outer armor layers are unilaterally impacted and stressed too much and are under unilateral pressure for a long time, due to uneven stress, the unilateral deformation is relatively large, and the tightness of the ring structure is greatly affected, resulting in a significant reduction in the sealing performance and a decline in the internal sealing and anti-corrosion performance of the cable.

[0004] In the prior art, the problem that the tightness of the ring structure of the inner and outer armor layers is reduced due to unilateral stress on the cable body, affecting the sealing and anti-corrosion performance, needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is, in view of the above-mentioned technical deficiencies, to provide a sealed and anti-corrosion load-bearing detection cable, which solves the problem in the prior art that the tightness of the ring structure of the inner and outer armor layers is reduced due to unilateral stress on the cable body, affecting the sealing and anti-corrosion performance.

[0006] The technical solution adopted by the present invention is: to provide a sealed and anti-corrosion load-bearing detection cable, including: A housing for sleeving on the cable body; A control panel, which is annular and rotatably sleeved on the housing, and a plurality of guiding parts are arranged in a circumferential array on the control panel; Pressure dividing members, there are several of them, and several of the pressure dividing members are circumferentially arrayed around the outer periphery of the sleeve. Each pressure dividing member has a supporting portion and a pressing portion. The supporting portion is used to abut against the wellbore wall. The pressure dividing member is movably arranged relative to the sleeve in the radial direction of the sleeve. After the pressure dividing member moves closer to the sleeve, the pressing portion abuts against the outer periphery of the sleeve or the outer periphery of the cable body. The pressure dividing member also has a connecting portion, and the connecting portion is slidably arranged relative to the guiding portion. When one of the pressure dividing members moves closer to the sleeve, the guiding portion is driven to rotate through the connecting portion. After the control disk rotates, the connecting portion is driven to move closer to the sleeve through the guiding portion.

[0007] To further optimize this technical solution, the guiding portion is a chute, the chute is inclined in the radial direction of the control disk, the connecting portion is a sliding rod, the sliding rod slides in the chute, and after the sliding rod moves closer to the sleeve in the chute, the sliding rod pushes the control disk to rotate. After the control disk rotates, the chute drives the sliding rod to move closer to the sleeve synchronously.

[0008] To further optimize this technical solution, it further includes: Conduits, there are several of them, which are circumferentially arrayed around the outer periphery of the sleeve. Each conduit has a compression spring inside, and the axial direction of the conduit is arranged along the radial direction of the sleeve; Guide rods, there are several of them, and one guide rod is arranged on each pressure dividing member. The guide rod is slidably sleeved in the conduit, and one end of the compression spring acts on the conduit and the other end acts on the guide rod, which is used to provide a force for the pressure dividing member to move away from the sleeve.

[0009] To further optimize this technical solution, the middle part of the pressure dividing member has a sliding plate, the sliding plate is located above the control disk, the connecting portion is arranged at the lower end of the sliding plate, the pressing portion is arc-shaped, the pressing portion is located on the side of the sliding plate close to the sleeve, the supporting portion is located on the side of the sliding plate away from the sleeve, and the guide rod is installed on the supporting portion.

[0010] To further optimize this technical solution, it further includes: An insect attracting box, which is arranged on the sleeve and is used to accommodate a lure for attracting insects; Adhesive, which is arranged on the insect attracting box and is used to stick insects approaching the cable body.

[0011] To further optimize this technical solution, the sleeve has a mounting pipe, and it further includes: A sleeve, which is arranged at the upper end of the insect attracting box, the sleeve is sleeved on the mounting pipe, and the sleeve and the mounting pipe are detachably connected by bolts.

[0012] To further optimize this technical solution, the insect trap box includes an arc-shaped side plate that fits against the outer wall of the housing. The insect trap box further includes an upper plate located at the upper end of the side plate and a lower plate located at the lower end of the side plate. Adhesive is provided on the lower side of the upper plate and the upper side of the lower plate. The side plate has a plug-in groove for accommodating the attractant.

[0013] The beneficial effects of the present invention are as follows: 1. By the support part of the voltage-dividing part abutting against the well wall, direct impact or friction between the local part of the cable body and the well wall can be avoided, reducing surface wear.

[0014] 2. After unilateral impact or pressure on the well wall, the voltage-dividing part moves closer to the housing and is transmitted to the cable body through the housing. A number of pressing parts surround the outside of the housing, so that each position in the circumferential direction of the housing is squeezed by the pressing parts, making the pressure evenly distributed on the circumferential surface of the cable body, avoiding the reduction of the tightness of the annular structure of the inner and outer armor layers caused by unilateral force, and making the forces on each position in the circumferential direction of each structural layer in the cable body more uniform, improving the stability of sealing and anti-corrosion.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0017] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, for the components with the same structure or function, only one of them is schematically shown, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0018] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0020] Such as Figure 1-10As shown, a sealed and corrosion-resistant load-bearing detection cable comprises: a casing 2 for being sleeved on a cable body 1; a control panel 3, which is annular and rotatably sleeved on the casing 2, and a plurality of guide portions 301 are arranged in a circumferential array on the control panel 3; a plurality of pressure dividing members 4, and a plurality of pressure dividing members 4 are arranged in a circumferential array on the periphery of the casing 2, the pressure dividing member 4 has a supporting portion 401 and a pressing portion 403, the supporting portion 401 is used to abut against the well wall, the pressure dividing member 4 is arranged to be movable relative to the casing 2 along the radial direction of the casing 2, after the pressure dividing member 4 moves close to the casing 2, the pressing portion 403 abuts against the periphery of the casing 2 or the periphery of the cable body 1, the pressure dividing member 4 also has a connecting portion 404, the connecting portion 404 and the guide portion 301 are arranged to slide relative to each other, when one of the pressure dividing members 4 moves close to the casing 2, the guiding portion 301 is driven to rotate through the connecting portion 404, and after the control panel 3 rotates, the connecting portion 404 is driven to move close to the casing 2 through the guiding portion 301.

[0021] When in use, the casing 2 is sleeved on the position on the cable body 1 that needs to be protected, such as the position that is easy to collide with the well wall. The casing 2 can be inserted from the end of the cable body 1 to the designated position and then tightly held, or the casing 2 can be a hoop structure that surrounds the cable body 1. An annular ring groove is arranged on the outer periphery of the casing 2, and the inner side of the control disk 3 rotates in the slide groove. The control disk 3 and the pressure dividing member 4 form relative movement through the interaction between the guide part 301 and the connecting part 404, and the pressure dividing member 4 moves along the radial direction of the casing 801.

[0022] When one or more of the pressure-dividing members 4 hit the well wall or are under pressure, the stressed pressure-dividing member 4 moves toward the casing 2, and acts on the guide portion 301 through the connecting portion 404, so that during the movement of the pressure-dividing member 4, the control disk 3 rotates at the same time, and after the control disk 3 rotates, it acts on the connecting portions 404 of other pressure-dividing members 4 through the guiding portion 301, driving the other pressure-dividing members 4 to move toward the casing 2 at the same time, and finally the pressure-dividing portions surrounding the outer periphery of the casing 2 exert pressure on the casing 2 in the circumferential direction, avoiding excessive difference between the force on one side and the force on other positions, and at the same time helping to reduce impact damage.

[0023] The pressing portion 403 can abut against the outer periphery of the casing 2 , and the pressing force transmits the casing 2 to the cable body 1 ; the pressing portion 403 can also abut against the outer periphery of the cable body 1 , and the pressing force acts on the outer surface of the cable body 1 .

[0024] Furthermore, the guide portion 301 is a slide groove, which is inclined relative to the radial direction of the control disk 3. The connecting portion 404 is a slide rod, which slides in the slide groove. After the slide rod moves in the slide groove and approaches the casing 2, the slide rod pushes the control disk 3 to rotate. After the control disk 3 rotates, the slide groove drives the slide rod to move synchronously close to the casing 2.

[0025] During use, the cooperation between the connecting part 404 and the guiding part 301 can refer to the circular hole necking mechanism. In this application, it is defined that the voltage dividing part 4 moves in the radial direction, which can reduce the rubbing of the pressing part 403 on the outer surface layer of the cable body 1, and the contact stability is better. There are two implementation manners. The first implementation manner is that the guiding part 301 is a chute structure, and chutes are arranged in a circumferential array on the control disk 3. The connecting part 404 is a sliding rod, and the chutes are inclined relative to the radial direction. When the sliding rod moves along the radial direction following the voltage dividing part 4 and approaches the housing 2, the sliding rod and the chutes move relative to each other, driving the control disk 3 to rotate. After the control disk 3 rotates, each chute drives the corresponding sliding rod to approach the housing 2 along the radial direction respectively. Finally, all the pressing parts 403 abut against the cable body 1 behind the housing 2.

[0026] The second implementation manner is that the connecting part 404 is a chute structure and the guiding part 301 is a sliding rod. Similarly, the mutual drive between the voltage dividing part 4 and the control disk 3 can be realized, and the principle is the same as above, so it will not be elaborated here. The chute structure can be an arc-shaped chute, one end is close to the housing 2 and the other end is far from the housing 2, and the connection line between the two ends is inclined relative to the radial direction of the housing 2.

[0027] Furthermore, it further includes: a plurality of conduits 5, which are arranged in a circumferential array on the periphery of the housing 2, and each conduit 5 is internally provided with a compression spring 6. The axis direction of the conduit 5 is arranged along the radial direction of the housing 2; a plurality of guide rods 7, and each voltage dividing part 4 is provided with a guide rod 7. The guide rod 7 is slidably sleeved in the conduit 5. One end of the compression spring 6 acts on the conduit 5 and the other end acts on the guide rod 7, for providing a force for the voltage dividing part 4 to move away from the housing 2.

[0028] During use, the movement of the voltage dividing part 4 along the radial direction can be defined by the conduit 5 and the guide rod 7, and the compression spring 6 can play a buffering role and a role in resetting the voltage dividing part 4. When the supporting part 401 of the voltage dividing part 4 is impacted, the guide rod 7 slides in the conduit 5 to compress the compression spring 6. When it breaks away from the wellbore wall, the compression spring 6 is released and the voltage dividing part 4 moves away from the housing 2.

[0029] Furthermore, the middle part of the voltage dividing part 4 has a sliding plate 402. The sliding plate 402 is located above the control disk 3. The connecting part 404 is arranged at the lower end of the sliding plate 402. The pressing part 403 is arc-shaped, the pressing part 403 is located on the side of the sliding plate 402 close to the housing 2, and the supporting part 401 is located on the side of the sliding plate 402 far from the housing 2. The guide rod 7 is installed on the supporting part 401.

[0030] During use, the voltage dividing part 4 can be a vertical upward pressing part 403 arranged on the inner side of the horizontal sliding plate 402. The pressing part 403 is arc-shaped and fits the outer surface of the cable body 1 or the outer surface of the housing 2. A vertical downward supporting part 401 is arranged on the outer side of the sliding plate 402, and the guiding rod is installed on the supporting part 401.

[0031] Further, it further includes: an insect attracting box 8, which is arranged on the sleeve 2 and is used for containing a lure for attracting insects; an adhesive 9, which is arranged on the insect attracting box 8 and is used for sticking the insects approaching the cable body 1.

[0032] During use, the gnawing of the outer surface of the cable body 1 by mosquitoes and the secretions, etc. will cause damage and corrosion to the cable body 1. The insect attracting box 8 can trap mosquitoes and reduce the damage to the cable body 1. Corresponding lures can be set according to the mosquitoes corresponding to the formation distribution or the use environment, etc., and the mosquitoes are stuck by the adhesive 9.

[0033] The adhesive 9 can be coated on the insect attracting box 8, and the lure is placed in the middle of the adhesive 9. The insect attracting box 8 can adopt an open structure, with a ring-shaped side plate 802 in the middle, and the upper plate 803 and the lower plate 804 are respectively located at the upper and lower ends of the side plate 802 and the adhesive 9 is provided, which is convenient for replacing the adhesive 9. A plurality of plug-in grooves 8021 can be arranged on the outer side of the side plate 802 away from the sleeve 2 for containing mosquito attracting devices such as lures, which is convenient for replacement according to different environments. And the adhesive 9 can also be arranged on the periphery of the plug-in groove 8021 on the side plate 802.
