Description

Technical Field

[0001] The utility model relates to the technical field of wellhead blowout prevention equipment operation, in particular to a window opening device for quickly installing a cable hanger. Background Art

[0002] In the existing cable pressure logging operation in oil and gas fields, due to the cable armor wire structure, in order to achieve the dynamic lifting and lowering sealing of the cable, the cable must pass through a thin and long choke tube with a gap of only 0.2 to 0.5 mm for several meters, and the throttling and pressure reduction effect of the thin and long gap is used to achieve the dynamic sealing of the cable. In addition, the cable is repeatedly lifted and lowered many times under complex well conditions, especially in large-angle horizontal logging operations. The cable will contact and rub against the tubing wall or casing wall during the process of the tool being pumped to the horizontal well section. The above reasons often cause the cable to wear, break wires, and deform. When the cable is damaged to varying degrees, it will affect its efficiency in passing through the sealing head choke tube with a small gap, and it may even get stuck at the bottom of the sealing head choke tube and form a "bird's nest", which will make it impossible to lift and lower the tool in the well, resulting in logging accidents.

[0003] In the traditional logging process, when such an accident occurs, the methods adopted on site are;

[0004] Step 1: Close the blowout preventer and release the pressure in the upper blowout preventer string;

[0005] Step 2: Disassemble the union connection between the lower catcher and the blowout preventer;

[0006] Step 3: Use a crane to forcibly lift the blowout preventer string up 1-2 meters to expose the cable;

[0007] Step 4: Install the cable hanging device at the exposed cables;

[0008] Step 5: Cut the cable and handle the accident.

[0009] This method of handling accidents has great safety risks:

[0010] Hidden danger 1: When forcibly raising the nozzle string, the cable is likely to break at the broken wire or deformed part, causing the tool to fall into the well.

[0011] Hidden danger 2: When the cable is being lifted, there is sliding friction between the cable and the front seal of the blowout preventer, which will damage the front seal of the blowout preventer, causing the blowout preventer to fail to seal the well and cause a blowout accident.

When the cable hanging device needs to be installed, the sealing ring slides to open the window hole. When the installation is completed, the sealing ring is sealed and installed on the window hole.

[0016] A sealing ring is arranged on the sealing ring.

[0017] The upper edge of the sealing ring is provided with a hanging platform for connecting and engaging with the upper catcher.

[0018] The hanging platform is fixedly installed on the upper edge of the sealing ring by screws.

[0019] A handle is installed on the sealing mechanism.

[0035] Specifically, the hanging platform 22 is fixedly mounted on the upper edge of the sealing ring 2 by means of screws, and a handle 3 is mounted on the sealing mechanism.

[0036] After the sealing ring 2 seals the window hole 11 , the window joint 1 is provided with a shoulder for limiting the sealing ring 2 to prevent the sealing ring 2 from further sliding down.

[0037] It should be noted that a groove 12 is provided in the middle of the window joint 1, the window hole 11 is provided on the groove 12, and a gap is provided between the window hole 11 and the sealing mechanism. The device to be connected includes a blowout preventer, a lower catcher, or a blowout preventer.

[0038] The working process of the utility model is:

[0039] When the cable hanging device needs to be installed, the sealing ring 2 is lifted up to reveal the window hole 11. At the same time, a hanging platform 22 is designed on the sealing ring 2 for suspending itself. The sealing ring 2 and the window joint 1 are sealed by the sealing ring 21 to achieve the sealing of the annular space.

[0040] like Figure 2-4 As shown, when the cable forms a "bird's nest" phenomenon in the sealing head, the sealing ring 2 is lifted up to expose the window hole 11, and the cable hanging device is quickly installed in the hole that leaks out.
