A wear-resistant reinforced sleeve for a setting tool

Abstract

This utility model discloses a wear-resistant reinforced sleeve for a setting tool, specifically relating to the field of setting tool technology. It includes a limiting cylinder with a connecting assembly. The connecting assembly includes a converging cone located in the middle of the limiting cylinder, with a converging cavity in the middle of the converging cone. The vertical cross-sectional shape of the converging cavity is frustum-shaped, and an installation sleeve is disposed within the converging cavity. This utility model, through the cooperation of the frustum-shaped converging cavity and the frustum-shaped installation sleeve, combined with the adjustment structure of the lead screw and nut, allows the installation sleeve to move axially by rotating the nut: when moving upwards, the inner space of the installation sleeve expands, accommodating larger-sized rubber tubes; when moving downwards, the space shrinks, accommodating smaller-sized rubber tubes. This breaks the limitation of one tool per tube, significantly improving the tool's adaptability to different specifications of rubber tubes and reducing operating costs.

Description

Technical Field

[0001] This utility model relates to the field of setting tools technology, and more specifically, to a wear-resistant reinforced sleeve for setting tools. Background Technology

[0002] A bridge plug is a downhole tool used to seal oil and gas wells. During the setting process, the bridge plug setting tool connected to it generates thrust or pull, which is applied to the bridge plug's slips and rubber sleeve, thus setting the plug. Therefore, bridge plugs must be used in conjunction with a bridge plug setting tool.

[0003] Among them, the patent with announcement number CN218030112U discloses a setting tool for a tubing bridge plug, including a body with a channel connected to the bridge plug, and multiple cavities connected to the channel on the outside of the body. Movable parts are provided in the cavities, and the movable parts are connected to the bridge plug slips and can drive the bridge plug slips to move.

[0004] When in use, the hot air is fixed in the channel with a valve seat. The valve seat is provided with a second through hole that connects to the channel. The second through hole allows the high-pressure fluid flowing outside to enter the cavity through the channel, driving the moving parts to move. However, this structure is not easy to position and install rubber tubes of different sizes when in use. This results in different tools being required for the installation of rubber tubes of different sizes, making it inconvenient to use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wear-resistant reinforced sleeve for a setting tool, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a wear-resistant reinforced sleeve for a setting tool, including a limiting sleeve, wherein a connecting component is provided on the limiting sleeve;

[0007] The connecting assembly includes a gathering cone cylinder disposed in the middle of the limiting cylinder, the gathering cone cylinder having a gathering cavity in the middle, the vertical cross-sectional shape of the gathering cavity being frustum-shaped, and an installation sleeve being disposed inside the gathering cavity.

[0008] The outer side of the mounting sleeve has several misaligned cavities, and the vertical cross-section of the mounting sleeve is shaped like a frustum.

[0009] Optionally, in one possible implementation, a lead screw is fixedly provided at the bottom end of the mounting sleeve, and a nut is threadedly connected to the outer side of the lead screw. The lead screw passes through the limiting cylinder and extends to the bottom of the limiting cylinder, and the nut is located on the bottom surface of the limiting cylinder and rotatably connected to the limiting cylinder. A washer is provided at the bottom end of the gathering cone, and the washer is located at the bottom of the inner wall of the limiting cylinder and is engaged with the limiting cylinder. An anti-slip protrusion is fixedly provided on the outer side of the gathering cone, and the anti-slip protrusion abuts against the inner wall of the limiting cylinder. The limiting cylinder, the gathering cone, and the mounting sleeve are all in the same axial direction, and the outer side of the mounting sleeve is in contact with the inner wall of the gathering cavity.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By using the combination of a frustum-shaped gathering cavity and a frustum-shaped mounting sleeve, along with the adjustment mechanism of the screw and nut, the mounting sleeve can be moved axially by rotating the nut: when moving upwards, the inner space of the mounting sleeve expands to accommodate larger-sized rubber tubes; when moving downwards, the space shrinks to accommodate smaller-sized rubber tubes. This breaks the limitation of one tool per tube, significantly improving the tool's adaptability to different specifications of rubber tubes and reducing operating costs.

[0012] The misaligned cavity on the outside of the mounting sleeve reduces the contact area with external components, thus reducing frictional loss. At the same time, the hollow structure formed by the misaligned cavity facilitates heat dissipation, preventing the material properties from deteriorating due to frictional heat. The anti-slip protrusions on the outside of the converging cone abut against the inner wall of the limiting cylinder, effectively preventing the converging cone from rotating radially during operation and ensuring positioning accuracy.

[0019] 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.

[0020] The wear-resistant reinforced sleeve of the setting tool disclosed in this embodiment aims to solve the problems of existing setting tools being difficult to adapt to rubber sleeves of different sizes and inconvenient installation and positioning. Its specific structure is as follows:

[0021] like Figure 1 As shown, the wear-resistant reinforced sleeve includes a limiting cylinder 1, which is a hollow cylindrical structure with a connecting component inside, used to achieve positioning and installation of the rubber sleeve and wear resistance reinforcement.

[0022] Connecting components such as Figure 2 As shown, it includes a conical cylinder 2 disposed in the middle of the limiting cylinder 1. A through-hole converging cavity is formed in the middle of the converging cylinder 2, and the vertical cross-section of the converging cavity is frustum-shaped, i.e., a conical structure that is wider at the top and narrower at the bottom. An mounting sleeve 3 is fitted inside the converging cavity. The vertical cross-section of the mounting sleeve 3 is also frustum-shaped, and its taper matches the taper of the converging cavity, allowing the outer side of the mounting sleeve 3 to be in close contact with the inner wall of the converging cavity. Figure 4 As shown.

[0023] like Figure 4 As shown, several misaligned cavities 4 are provided through the outer side of the mounting sleeve 3. The misaligned cavity 4 is a long strip-shaped through hole. This design can reduce the contact area between the mounting sleeve 3 and the external parts, thereby reducing friction and wear. At the same time, it facilitates heat dissipation, improves wear resistance, and also makes it easier for the mounting sleeve 3 to be tightened axially under force.

[0024] like Figure 2 and Figure 4 As shown, a lead screw 5 is fixedly welded to the center of the bottom end of the mounting sleeve 3, and a nut 6 is threadedly connected to the outside of the lead screw 5. The bottom end of the lead screw 5 vertically penetrates the bottom wall of the limiting cylinder 1 and extends to the outside of the limiting cylinder 1. The nut 6 is sleeved on the part of the lead screw 5 located outside the limiting cylinder 1, and the top end of the nut 6 abuts against the bottom surface of the limiting cylinder 1. By rotating the nut 6, the lead screw 5 can be driven to move up and down axially.

[0025] like Figure 3 As shown, several anti-slip protrusions 8 are integrally formed on the outer wall of the converging cone 2. The anti-slip protrusions 8 are evenly distributed along the circumference of the converging cone 2, and their outer walls are in close contact with the inner wall of the limiting cylinder 1. This is used to prevent the converging cone 2 from rotating relative to the limiting cylinder 1 and to ensure structural stability.

[0026] like Figure 2 As shown, a washer 7 is also provided at the bottom end of the converging cone 2. The washer 7 is an annular structure, and its outer wall is engaged with the inner wall of the limiting cylinder 1. The top end of the washer 7 abuts against the bottom end of the converging cone 2, which is used to provide axial support for the converging cone 2 and prevent it from sliding downward.

[0027] like Figure 1 As shown, the axes of the limiting cylinder 1, the gathering cone cylinder 2, and the mounting sleeve 3 are completely coincident, that is, the three are on the same axial direction. This design can ensure the coaxiality of the rubber sleeve during installation and avoid the aggravation of local wear caused by eccentricity.

[0028] The specific working principle is as follows: when different sizes of rubber sleeves need to be installed, the operator can adjust the position of the installation sleeve 3 by rotating the nut 6:

[0029] If the rubber tube is large, turn the nut 6 clockwise. Under the action of the threaded engagement, the screw 5 drives the mounting sleeve 3 to move upward along the axis. Since both the mounting sleeve 3 and the gathering cavity are frustum-shaped, when moving upward, the contact position between the outer wall of the mounting sleeve 3 and the inner wall of the gathering cavity moves upward, and the inner accommodating space of the mounting sleeve 3 expands accordingly to accommodate larger rubber tubes.

[0030] If the rubber tube is small, turn the nut 6 counterclockwise, and the screw 5 will drive the mounting sleeve 3 to move downward along the axis. The contact position between the outer wall of the mounting sleeve 3 and the inner wall of the gathering cavity will move downward, and the inner accommodating space of the mounting sleeve 3 will shrink to accommodate the smaller rubber tube.

[0031] After the rubber tube is installed, the outer wall of the rubber tube fits against the inner wall of the mounting sleeve 3. The mounting sleeve 3 makes close contact with the inner wall of the gathering cavity of the gathering cone 2 through its outer wall, thus achieving stable positioning of the rubber tube. At the same time, the misalignment cavity 4 reduces the friction area between the mounting sleeve 3 and external components, while the anti-slip protrusion 8 and the washer 7 ensure the stability of the gathering cone 2 from the radial and axial directions, respectively, and prevent structural loosening caused by vibration.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
