Description

Technical Field

[0001] This utility model relates to the field of petroleum open technology, specifically a portable cable fixing clip. Background Technology

[0002] In current integrated measurement and control and thermal recovery testing projects, the installation of the blowout preventer (BOP) typically relies on a hydraulic lifting system. This system first requires placing the BOP horizontally on a lifting support, then using a hydraulic system to gradually raise it from a horizontal to a vertical position for docking with the wellhead sub. During this process, because the BOP contains various instruments and counterweights, additional securing measures must be taken to prevent them from slipping as the BOP changes from a vertical to a tilted position. To ensure the safety of this process, two common practices exist. One is to have dedicated personnel manually hold the cables, directly controlling the position of the instruments and counterweights to prevent them from slipping out of the BOP. The other method is to use a hand pump to pressurize the packing, increasing friction to stabilize the position of the instruments and counterweights. However, both methods have certain limitations and risks.

[0003] 1. If the cable is secured by manually dragging it, it must be correctly installed onto the pulleys for guidance. This process is not only time-consuming and labor-intensive, but also increases labor costs and safety risks. Furthermore, the force generated by dragging the cable may impact the hydraulic lifting device, affecting its normal operation. Especially during sampling tests in thermal wells, the plug packing cannot effectively secure the steel wire, so it must be secured manually by grasping the wire. This not only increases the difficulty of operation and safety hazards, but may also cause burns and other injuries to workers.

[0004] 2. When the total weight of the instrument and counterweight exceeds 20 kg, relying solely on a hand pump to compress the packing may not provide sufficient stability. In this situation, the instrument and counterweight may slip out of the blowout preventer and impact the gate valve or wellhead sub, causing serious equipment damage or a safety accident.

[0005] Announcement No. CN210404580U discloses a cable fastening device for a pressure-driven monitoring well testing instrument, comprising: a cable clamp mechanism; the cable clamp mechanism comprising: a clamp assembly and a locking assembly; the clamp assembly having a clamping jaw; the clamp assembly clamping the cable radially into the clamping jaw; the clamping jaw contacting the cable surface; and the locking assembly connected to the clamp assembly for fixing the cable to the clamping jaw.

[0006] The existing technology for securing the cable is relatively cumbersome, and the cable's movement can cause the annular groove of the second locking member to disengage from the wellhead fixing clip connection hole.

[0007] Announcement No.: CN221263196U discloses a quick-positioning cable clamp for oil production pipes, including an installation plate. A movable plate is provided at the front end of the installation plate. Several clamping mechanisms are equidistantly installed at the front end of the movable plate. A quick-release assembly is installed between the movable plate and the installation plate. A bidirectional screw is rotatably connected inside the installation plate. One side of the bidirectional screw passes through and extends to the outside of the installation plate and is fixed with a handwheel. Two connecting rods are symmetrically sleeved on both sides of the outer layer of the bidirectional screw.

[0008] The existing technology for securing cables requires the cables to pass through a clamping mechanism, which cannot be applied to securing cables in blowout preventers.

[0009] Announcement No.: CN221300941U discloses a combined fixing device for deep-sea hydrophones and a deep-sea hydrophone array cable, including a cable, a fixing bracket, a hydrophone body, a first fixing block, a second fixing block, a spacing adjustment component, and a clamping assembly. The fixing bracket is connected to the cable and is composed of the first fixing block, the second fixing block, the spacing adjustment component, and the clamping assembly. The first fixing block and the second fixing block are engaged with each other on both sides of the cable.

[0010] The existing technology for fixing cables is relatively cumbersome, and the efficiency of assembling and disassembling cables is not as good as that of this utility model.

[0011] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] Please see Figures 1 to 2 This utility model provides a portable cable fixing clip, comprising a tube fixing part 1, a connecting part 2, and a cable fixing part 3 connected in sequence. The tube fixing part 1 is used to connect a blowout preventer 6, and the cable fixing part 3 is used to fix a cable 5. The cable fixing part 3 includes a base 31, a first fixing claw 32 and a second fixing claw 33 that can engage. The first fixing claw 32 and the second fixing claw 33 are rotatably connected to the base 31. The base 1 is connected to the connecting part 2. A cable slot 323 is provided through the engaging surface of the first fixing claw 32 and the second fixing claw 33. A cable locking element is provided on the first fixing claw 32 and the second fixing claw 33. The cable clip is fixedly connected to the blowout preventer 6 through the tube fixing part 1, and then the cable 5 is placed into the cable slot 323. The first fixing claw 32 and the second fixing claw 33 are locked with the cable locking element to complete the fixing of the cable 5.

[0036] Specifically, the base 31 is a U-shaped base. The ends of the first fixing claw 32 and the second fixing claw 33 away from the cable slot 323 are fitting connection ends. The fitting surface of the connection end is perpendicular to the mating surface. The connection end is provided with a through rotating hole. The axis of the rotating hole is parallel to the mating surface. The connection end is located inside the U-shaped base. The U-shaped base is provided with a movable pin 34. The movable pin 34 passes through the two arms of the U-shaped base and through the rotating hole. The fitting surface of the connection end is perpendicular to the mating surface, so that the first fixing claw 32 and the second fixing claw 33 can be rotated open. The connection end can be provided with a U-shaped female head for the first fixing claw 32 and a single male head for the second fixing claw 33, which fit together.

[0037] The movable pin 34 has a ring at its upper end, and a locking rope is provided on the ring. The end of the locking rope away from the ring is fixedly connected to the connecting part 2 to lock the movable pin 34. The locking rope can be a steel wire rope.

[0038] Specifically, the cable locking component includes a screw 35 and a locking nut 36. The first fixing claw 32 and the second fixing claw 33 are provided with through locking holes 322. The axis of the locking hole 322 is perpendicular to the axis of the rotating hole. The screw 35 is located inside the locking hole 322. One end of the screw 35 is provided with a limit cap, and the other end is threaded to the locking nut 36. The locking of the first fixing claw 32 and the second fixing claw 33 is achieved by tightening the locking nut 36.

[0039] Preferably, the locking nut 36 is a wing nut, which is easy to install and remove, and the limiting cap is a hexagonal cap, which is convenient for tools to clamp and fix the screw 35 or to apply force from both sides at the same time, and can achieve a clamping force of 60 kg.

[0040] Specifically, the cross-section of the cable slot 323 is a semi-oblong hole. The cable slots 323 on the first fixing claw 32 and the second fixing claw 33 are joined together to form an oblong hole. This shape prevents the cable slot 323 from causing significant wear to the cable 5.

[0041] Preferably, the locking hole 322 is located between the cable slot 323 and the rotating hole, so that the cable 5 can be directly removed after the first fixing claw 32 and the second fixing claw 33 are loosened.

[0042] Preferably, the cable slot 323 is designed with two specifications: steel pipe cable and steel wire, based on the diameter of the currently used cable. When using it, the appropriate specification is selected to meet the needs of the project department for integrated measurement and adjustment and on-site construction of thermal well testing.

[0043] Specifically, the pipe fixing part 1 is in the shape of a clamp, and its diameter matches that of the blowout preventer 6 on site. The pipe fixing part 1 is equipped with a locking pin 4 with a radial through thread connection. The clamp is existing technology, so it will not be described in detail and no drawings are provided.

[0044] Specifically, the connecting part 2 is a connecting plate, which is welded to the pipe fixing part 1 and the base 31. The minimum parallel distance between the cable 5 and the blowout preventer 6 is determined by measuring the distance between the pulley and the blowout preventer 6 on site, and the length of the connecting plate is obtained.

[0045] Example 2:

[0046] Based on Embodiment 1, in this embodiment, a spring mounting blind hole 321 is provided at the mating surface of the first fixing claw 32 and the second fixing claw 33, and a spring 37 is provided in the spring mounting blind hole 321. After the first fixing claw 32 and the second fixing claw 33 are mated, the spring 37 is in a compressed state. After the cable locking component is loosened, the first fixing claw 32 and the second fixing claw 33 automatically open, making it easy to take out the cable 5.

[0047] Preferably, the spring mounting blind hole 321 is located between the locking hole 322 and the rotating hole.

[0048] Preferably, the cable clips are made of stainless steel, which can be used for a long time without rust.

[0049] Example 3:

[0050] Based on Example 2, this example provides a field implementation method:

[0051] First, the operator installs the hydraulic lifting device onto the wellhead sub. After installation, the next step is to install the blowout preventer (BOP). Once the BOP is installed, the operator can load the instruments to be run into the BOP. After the instruments are installed, tighten the plug to ensure that the instruments will not fall off or be damaged during the running-in process.

[0052] The cable 5 is arranged and placed. The cable 5 must be straightened and placed in the cable 5 clamp to ensure that it will not be stuck or twisted during the well process. Specifically, the pipe fixing part 1 is connected to the blowout preventer 6, the connecting part 2 is adjusted to be consistent with the direction of the pulley, and the fixing knob is tightened to ensure the stability and safety of the entire well process. The pipe fixing part 1 and the blowout preventer 6 are locked with clamp bolts and locking pins 4. The cable 5 is placed into the cable slot 323 and the locking nut 36 is tightened so that the first fixing claw 32 and the second fixing claw 33 clamp the pipe armored cable 5.

[0053] After preparation, the operator can use the hydraulic pump to lift the lifting frame. Lifting the lifting frame will cause the blowout preventer to move vertically to above the wellhead short section. After the blowout preventer is connected and secured to the wellhead short section, the operator needs to put cable 5 into the pulley and tighten cable 5 to ensure that the instrument can be smoothly lowered into the well and will not be obstructed during the lowering process.

[0054] After the above steps are completed, the wellhead operator avoids cable 5, loosens the locking nut 36, and removes cable 5 from the cable clamp; then the instrument is fully inserted into the wellhead and testing begins.

[0055] After the instrument test is completed, first, it is necessary to ensure that the test gate is closed and emptied to prevent any possible leakage or accident; then, the operator needs to tighten cable 5 so that the instrument is fully inserted into the blowout preventer; next, put cable 5 into cable slot 323 and tighten lock nut 36 to ensure that the instrument will not fall off or be damaged during the removal process.

[0056] Finally, the operator can use the hydraulic lifting device to tilt the blowout preventer, thereby completing the instrument removal operation.

[0057] After the cable clamp was designed and manufactured, it underwent two rounds of experimental improvements, and four sets were finalized and manufactured. The processing cost for each set was 980 yuan, totaling 3,920 yuan. After processing and manufacturing, it was deployed in four measurement and adjustment vehicle groups and used in more than 800 well operations. In particular, for pressure drive measurement and adjustment projects, since the wellhead pressure is higher than 30 MPa, the measurement and adjustment instruments need to be attached with five 10 kg weight rods. Without the cable clamp, on-site construction would not be possible. Currently, the cable clamp has become a standard auxiliary tool for the project department's measurement and adjustment team. The cable clamp can not only be used in measurement and adjustment projects, but also for the rapid handling of wellhead wires when instruments get stuck, which greatly improves on-site handling efficiency.
