Description

Technical Field

[0001] This utility model relates to the technical field of oil well tree maintenance tools, specifically a special tool for removing the sealing packing of an oil well tree. Background Technology

[0002] An oil well is a hole drilled using drilling methods. Generally, after drilling to the oil layer, an oil layer casing is run in, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and water layers. Then, according to the requirements of oilfield development, the oil layer is perforated with a perforating gun to form a channel, and an oil tubing is run in. Using appropriate flow induction methods, oil is raised from the bottom of the oil well to the wellhead. The sealing packing is the sealing packing inside the packing box on the production tree.

[0003] In traditional operations, technicians often use a flathead screwdriver to pry open the packing box. Because the packing box itself has a certain degree of toughness, while the screwdriver tip is made of hard material, friction and wear are easily generated when the tip comes into contact with the top of the packing box during the prying process. Long-term and frequent operations of this kind will cause varying degrees of damage to the top of the packing box, which will affect its overall structural stability and ultimately shorten the service life of the packing box. Utility Model Content

[0004] The purpose of this utility model is to provide a special tool for removing the sealing packing of the oil well tree, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special tool for removing sealing packing from an oil well tree, comprising a handle, wherein a cutting head is fixedly connected to the bottom end of the handle;

[0006] Both the handle and the blade are provided with sliding grooves. The handle is threaded with a lifting box. The blade is provided with a protective adjustment mechanism. The protective adjustment mechanism includes a lifting rod and a passage groove. The lifting rod is fixedly connected with symmetrically arranged connecting blocks. The connecting blocks are all fixedly connected with a rubber ring. The handle is fixedly connected with symmetrically arranged lever rods.

[0007] Preferably, the bottom end of the cutter head is flat.

[0008] Preferably, the rubber ring is slidably sleeved on the cutter head.

[0009] Preferably, the lifting rod is slidably connected inside the bottom sliding groove, and the top sliding groove of the lifting rod is rotatably connected to the lifting box.

[0010] Preferably, the passage grooves are symmetrically formed on the cutter head, and all the passage grooves are in communication with the bottom sliding groove. One end of each connecting block slides through the corresponding passage groove and is fixedly connected to the rubber ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when using the lever of a screwdriver, the rubber ring can be moved in advance to the position of the lever action point formed by the screwdriver, so as to protect the top of the packing box. In subsequent operations, the top of the packing box can be protected from direct wear under the protection of the rubber ring, avoiding wear and damage due to long-term use, and significantly improving the practicality and functionality of the tool in actual application.

[0016] 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.

[0017] Please see Figure 1-3 The present invention provides the following technical solution:

[0018] Example 1: A special tool for removing sealing packing from an oil well tree, comprising a handle 1, with a cutter head 2 fixedly connected to the bottom end of the handle 1, the bottom end of the cutter head 2 being flat.

[0019] When using, hold the handle 1 and insert the blade 2 into the packing box, then lift the sealed packing and use the top of the packing box to slowly pick the packing out of the packing box.

[0020] Example 2: The technical solution of this example that differs from that of Example 1 includes: a sliding groove 3 is provided on both the handle 1 and the cutter head 2; a lifting box 4 is threadedly connected to the handle 1; a protective adjustment mechanism 5 is provided on the cutter head 2; the protective adjustment mechanism 5 includes a lifting rod 51 and a passage groove 52; symmetrically arranged connecting blocks 53 are fixedly connected to the lifting rod 51; rubber rings 54 are fixedly connected to the connecting blocks 53; and symmetrically arranged lever rods 6 are fixedly connected to the handle 1.

[0021] Rubber ring 54 is slidably sleeved on the cutter head 2. Lifting rod 51 is slidably connected to the bottom sliding groove 3. The top end of lifting rod 51 slides through the top sliding groove 3 and is rotatably connected to lifting box 4. Passage grooves 52 are symmetrically opened on the cutter head 2. All passage grooves 52 are in communication with the bottom sliding groove 3. One end of connecting block 53 slides through the corresponding passage groove 52 and is fixedly connected to rubber ring 54.

[0022] In use, the cutter head 2 can be inserted into the packing box, and then the lifting box 4 can be rotated. The lifting box 4 moves downward, which will drive the lifting rod 51 to move together. The lifting rod 51 will slide downward inside the top sliding groove 3 and the bottom sliding groove 3. The sliding of the lifting rod 51 will drive the two connecting blocks 53 to move together. The connecting blocks 53 will slide inside the passage groove 52, and at the same time, they will drive the rubber ring 54 to move downward. The connection between the rubber ring 54 and the cutter head 2 has a large friction force. If the operator pushes the rubber ring 54 directly, it will be very difficult. Then, the rubber ring 54 can be moved to a suitable position on the cutter head 2 by the driving of the connecting blocks 53. At this time, when the cutter head 2 uses the top of the packing box as a lever again, it will press the rubber ring 54 against the top of the packing box. At this time, the lever 6 can be used to apply force to the handle 1, so that the sealed packing can be slowly picked out of the packing box by the cutter head 2.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
