Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically a packer that facilitates unblocking. Background Technology

[0002] In the oil extraction process, plugging devices are used to isolate target formations during well completion or workover. The plugging device is first lowered into the predetermined position through the tubing string, and then expanded and sealed to the well wall using hydraulic or mechanical means. Oil and gas are then released in conjunction with processes such as perforation and fracturing. After extraction, the plugging device can be removed through the unsealing mechanism or left in the well to complete the sealing of the formation.

[0003] A plug is a tool used to isolate spaces such as pipelines and wells. It achieves isolation by expanding and fitting the sealing components to the inner wall. It is often equipped with auxiliary structures such as pressure relief and unblocking to deal with blockage scenarios. It is widely used in pipeline sealing operations in fields such as oil and gas extraction and municipal engineering.

[0004] After the plug is placed inside the pipe, it will come into contact with the liquid inside the pipe. During this contact, some fine impurities and dust will adhere to the plug through the adjustment and enter the plug. Over time, this will cause blockage of the plug.

[0005] Therefore, a sealing device that facilitates unblocking is proposed to address the above problems. Utility Model Content

[0009] Preferably, the inner wall of the interception net is fixed with hooks; multiple hooks are provided on the interception net; by adding hooks, the interception net can be engaged by hooks when connected, and thus the net can be restrained and engaged through the holes on the surface of the interception net during installation, thereby increasing the convenience of installation.

[0011] Preferably, a hollow threaded rod is fixedly connected inside the mounting groove; the hollow threaded rod and the mounting groove are correspondingly arranged; the hollow threaded rod and the mounting bolt are threadedly connected; the hollow threaded rod and the installation / removal hole are slidingly fitted; by adding the hollow threaded rod, the installation / removal hole can be quickly installed during the installation of the interception net through the guidance of the hollow threaded rod, which speeds up the restriction of the interception net during installation, and then the installation bolt and the hollow threaded rod are combined to speed up the fixation of the interception net.

[0012] Preferably, a washer is slidably fitted in the middle of the mounting bolt; the washer is located between the mounting bolt and the mounting groove; by adding the washer, the deformation of the washer can increase the friction when the mounting bolt fixes the interception net, thereby increasing the stability of the fixing when the mounting bolt fixes the interception net through friction.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the figure, the facilitating sealing device of this utility model includes a sealing device body 1. The sealing device body 1 has an upper connection port 11 at the top and a lower connection port 12 at the bottom. A sealing component 13 is installed inside the sealing device body 1. Multiple mounting slots 14 are provided in the middle of the sealing device body 1. An intercepting net 15 is provided inside the mounting slot 14. The intercepting net 15 and the mounting slot 14 are connected by multiple mounting components 16. The intercepting net 15 is elastic. In operation, the intercepting net 15 is first moved to both sides and then snapped onto the sealing device body 1. At this time, the intercepting net 15 can be placed inside the mounting slot 14 and then installed and fixed by multiple mounting components 16. After fixing, the sealing device body 1 is placed as a whole into the pipe. Inside the pipe, the slips on the plug body 1 are first used to secure it against the inner wall of the pipe. Then, the plugging assembly 13 is used to move closer to the inner wall of the pipe, and finally the pipe is sealed. The working principle of the plug body 1 is a mature existing technology, so it will not be described in detail here. When the liquid flows through the interception net 15 during the operation of the plug body 1, the interception net 15 will filter the mud and sand, reducing the contact between the mud and sand and the slip adjustment point, thus allowing the mud and sand to be intercepted by the interception net 15. After the plug body 1 is removed, the interception net 15 can be disassembled by the installation assembly 16 for cleaning. By adding the interception net 15, mud and sand can be intercepted at the adjustment point, reducing the amount of mud and sand entering the adjustment point when the pipe is working inside, thereby protecting it and extending the service life of the plug body 1.

[0026] like Figures 1 to 5 As shown, the installation assembly 16 includes multiple mounting bolts 2; the mounting bolts 2 and the mounting groove 14 are threadedly connected; the bottom of the interceptor net 15 has multiple installation and removal holes 21; the installation and removal holes 21 and the mounting bolts 2 are in sliding fit; during operation, after the blocker body 1 is removed from the pipeline as a whole, the mounting bolts 2 can be disassembled to remove it from the inside of the mounting groove 14, and then one end of the interceptor net 15 can be moved to deform it, and then peeled off from the blocker body 1. After peeling, the interceptor net 15 can be cleaned to remove the mud and sand debris attached to its surface; by using the mounting bolts 2 and the installation and removal holes 21 to install the interceptor net 15, the interceptor net 15 can be stably fixed by the thread engagement after placement, thereby increasing the stability of the interceptor net 15 after installation, and increasing its stability when blocking mud and sand for the blocker body 1.

[0027] like Figure 4As shown, hooks 3 are fixed to the inner wall of the interception net 15; multiple hooks 3 are provided on the interception net 15; during operation, when the interception net 15 is placed on the mounting groove 14, the end of the hook 3 can hook the other end of the interception net 15 to lock it in place, thereby increasing the traction for locking the connection before installation by hooking the end of the hook 3; by adding hooks 3, the interception net 15 can be locked in place during connection, thereby increasing the convenience of installation by locking it in place through the holes on the surface of the interception net 15.

[0028] like Figure 4 As shown, a pair of fixing plates 4 are provided at the end of the interception net 15; a pair of connecting bolts 41 are threadedly connected to the middle of the fixing plates 4; the connecting bolts 41 and the interception net 15 are threadedly connected; during operation, after the interception net 15 is installed, a pair of fixing plates 4 can be placed on the interception net 15, and then the fixing plates 4 are installed on the interception net 15 by a pair of connecting bolts 41, so that the fixing plates 4 increase the connection stability at the junction of the interception net 15; by adding fixing plates 4, the junction can be joined together by fixing plates 4 when the interception net 15 is joined, thereby increasing the fixing effect and increasing the stability of the junction after installation.

[0029] like Figure 3 As shown, a hollow threaded rod 5 is fixedly connected inside the mounting groove 14; the hollow threaded rod 5 and the mounting groove 14 are correspondingly arranged; the hollow threaded rod 5 and the mounting bolt 2 are threadedly connected; the hollow threaded rod 5 and the installation / removal hole 21 are slidingly fitted; during operation, when installing the interceptor net 15, the installation / removal hole 21 and the hollow threaded rod 5 are inserted accordingly. When inserted, the position of the interceptor net 15 is restricted, which increases the guiding restriction during installation. Then, the mounting bolt 2 is installed inside the hollow threaded rod 5. By adding the hollow threaded rod 5, the installation / removal hole 21 can be quickly installed during the installation of the interceptor net 15 through the guidance of the hollow threaded rod 5, which speeds up the restriction of the interceptor net 15 during installation. Then, the installation bolt 2 and the hollow threaded rod 5 are combined, thereby speeding up the fixing of the interceptor net 15.

[0030] like Figure 5 As shown, a washer 6 is slidably fitted in the middle of the mounting bolt 2; the washer 6 is located between the mounting bolt 2 and the mounting groove 14; during operation, when using the mounting bolt 2 to fix the intercepting net 15, after placing the intercepting net 15, the washer 6 is first put onto the mounting bolt 2, and then the mounting bolt 2 is installed on the hollow threaded rod 5 so that it continuously pushes the washer 6 towards the intercepting net 15, and squeezes it after contact, thereby increasing the friction of the mounting bolt 2 after fixing; by adding the washer 6, the deformation of the washer 6 can increase the friction when the mounting bolt 2 fixes the intercepting net 15, thereby increasing the stability of the fixing when the mounting bolt 2 fixes the intercepting net 15 through friction.

[0031] Working principle: First, the interceptor net 15 is moved from the middle to both sides and then clipped onto the plugging device body 1. At this point, the interceptor net 15 can be placed inside the mounting slot 14 and then fixed using multiple mounting components 16. After fixing, the plugging device body 1 is placed entirely inside the pipe. First, the clips on the plugging device body 1 are used to firmly adhere to the inner wall of the pipe for fixation. Then, the plugging component 13 is used to move closer to the inner wall of the pipe, finally sealing the pipe. The working principle of the plugging device body 1 is a mature existing technology and will not be elaborated here. When the liquid flows through the interceptor 15 during operation of the plug body 1, the interceptor 15 filters out sediment, reducing contact between sediment and the adjusting part of the slip, thus allowing sediment to pass through the interceptor 15. After the plug body 1 is removed, the interceptor 15 can be disassembled using the installation assembly 16 for cleaning. After the plug body 1 is completely removed from the pipeline, the installation bolts 2 can be removed to move it out of the installation groove 14. Then, one end of the interceptor 15 can be manipulated to deform it, and then it can be peeled off from the plug body 1. Afterwards, the interception net 15 can be cleaned to remove any mud and debris adhering to its surface. When placing the interception net 15 into the mounting slot 14, the end of the hook 3 can be hooked onto the other end of the interception net 15 to lock it in place. The hook 3 provides traction for the locking connection before installation. After the interception net 15 is installed, a pair of fixing plates 4 can be placed on it, and then the fixing plates 4 can be installed onto the interception net 15 using a pair of connecting bolts 41. This increases the stability of the connection at the junction of the interception net 15. When installing the net 15, insert the mounting hole 21 and the hollow threaded rod 5 into the corresponding holes. When inserted, the position of the net 15 will be restricted, which will increase the guiding restriction during installation. Then, the mounting bolt 2 will be installed into the hollow threaded rod 5. When fixing the net 15 with the mounting bolt 2, after placing the net 15, first put the washer 6 onto the mounting bolt 2, and then install the mounting bolt 2 onto the hollow threaded rod 5 so that it will continuously push the washer 6 towards the net 15. After contact, it will be squeezed, thereby increasing the friction of the mounting bolt 2 after fixing.
