Description

Technical Field

[0001] This utility model relates to the field of seat sealing and release technology, and more specifically to a seat sealing and release device. Background Technology

[0002] Setting and release devices are crucial equipment in petroleum engineering used to achieve the setting and release functions of tools such as packers and bridge plugs. Hydraulic pressure is applied to the downhole tool through tubing or other channels. When the pressure reaches a certain value, the hydraulic pressure drives the piston, push rod, and other components to move, compressing the rubber sleeve and causing it to expand and tightly adhere to the inner wall of the casing, achieving a seal. Simultaneously, it pushes the slips and other anchoring components to extend, fixing the tool to the casing wall, completing the setting. For example, in an integrated retrievable bridge plug, after the ball is dropped to seal the central tube, hydraulic pressure enters the piston through the pressure transmission hole. When the pressure reaches 8-10 MPa, the starting pin is sheared, and the piston descends, sequentially pushing the relevant components, causing the slips to extend and anchor the casing, compressing the rubber sleeve to form a seal. Once setting is complete and certain conditions are met, the setting tool is separated from the downhole tool by shearing the pin, breaking the threaded connection, or other mechanical means, achieving release. For example, in a hydraulic integrated cement retainer, the tubing is pressurized to a certain pressure to shear the starting pin, pushing the relevant components to complete the setting, and then the release pin is sheared to achieve release.

[0003] For example, the existing technology disclosure number CN217841579U is a large-diameter suspended release packer. This utility model adopts a large-diameter, large-suspension-force design, with an inner diameter larger than that of conventional suspended release packers. The reverse short-connection is pressed against the release joint through the pressure transmission ring, so that this utility model will not be damaged when encountering obstruction during the well running process. After the suspended release packer is set, the locking ring has a tapered toothed buckle inside, which locks with the toothed buckle at the upper end of the center tube, which can prevent the protruding slips and the expanded rubber sleeve assembly from rebounding. The inner hole at the upper end of the release joint has an internal thread of the tubing, which facilitates subsequent tool retrieval operations.

[0004] However, the existing technology described above still has the following problems in use: the traditional sealing release device lacks a protective structure on the outer wall to protect the rubber cylinder. When the operator is operating the device, the rubber cylinder is easily damaged by impact, which will affect the sealing performance of the entire device. Based on this, the present invention provides a sealing release device with a protective structure. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a sealing and dispensing device. The device body is wrapped with a rubber tube by two protective shells, which prevents the rubber tube from being damaged by objects during carrying and use, thus affecting the subsequent sealing performance. At the same time, the two protective shells are fixed by insert plates and snap-fit ​​components, which makes it easy for workers to quickly install and remove the protective shells. In addition, the protective shells can be recycled and reused, thereby reducing costs and waste, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seated sealing and releasing device, comprising a device body, on which a plurality of evenly distributed rubber tubes are fixedly mounted, and a protective assembly is provided on the device body. The protective assembly includes two protective shells fitted onto the outer wall of the device body for protecting the plurality of rubber tubes. Connecting plates one are fixedly mounted on both sides of the upper protective shell, and connecting plates two are fixedly mounted on both sides of the lower protective shell. Insert plates are fixedly mounted at the bottom of the two connecting plates one, and slots are opened at the top of the two connecting plates two. The insert plates are inserted into the slots, and snap-fit ​​components for fixing the insert plates are fixedly embedded on the outer wall of the two connecting plates two.

[0007] In a preferred embodiment, the outer wall of the device body is machined with an annular groove, and both protective shells are disposed inside the annular groove. The annular groove is used to limit the position of the protective shells, thereby improving the stability of the protective shells.

[0008] In a preferred embodiment, multiple positioning rods are fixedly provided on the inner walls of both protective shells. The inner wall of the annular groove is machined with positioning holes of the same number as the positioning rods. The positioning rods are inserted into the positioning holes. With the help of the positioning rods, the operator can improve both the accuracy of the protective shell installation position and the installation efficiency of the protective shell.

[0009] In a preferred embodiment, the snap-fit ​​assembly includes two sleeves, each sleeve having a sliding insert rod inside. The outer walls of the two insert plates each have insertion holes adapted to the insert rods. The insert rods are inserted into the insertion holes to fix the insert plates, which can improve the connection between the two protective shells and facilitate workers to quickly disassemble the protective shells.

[0010] In a preferred embodiment, each of the two insertion rods is fixedly provided with a pull rod at the end away from the insertion hole. A return spring is sleeved on the outer wall of the pull rod. The two ends of the return spring are fixed to the inner wall of the sleeve and the insertion rod, respectively. One end of the pull rod passes through the sleeve and extends out of the outer wall of the sleeve. The insertion rod is supported by the return spring, thereby improving the stability of the insertion rod.

[0011] In a preferred embodiment, each of the two connecting plates is provided with a pull plate on its outer side. The pull plate is fixed to the two pull rods. Each of the two connecting plates has two mounting holes on its outer wall. The two sleeves are fixed in the two mounting holes respectively. The sleeves are located in the mounting holes and are limited by the mounting holes, which can improve the stability of the sleeves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention features two protective shells on the outer wall of the device body to enclose the rubber tube on the device body, preventing damage to the rubber tube from impacts during transport and use, which would affect the subsequent sealing performance. At the same time, the two protective shells are fixed by insert plates and snap-fit ​​components, making it easy for staff to quickly install and remove the protective shells. In addition, the protective shells can be recycled and reused, thereby reducing costs and waste. Attached Figure Description

[0022] 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.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a seat sealing and release device, including a device body 1, on which a plurality of evenly distributed rubber tubes 2 are fixedly mounted. The device body 1 is provided with a protective component 3, which includes two protective shells 31 fitted on the outer wall of the device body 1 for protecting the plurality of rubber tubes 2. The outer wall of the device body 1 is machined with an annular groove 5, and the two protective shells 31 are both located inside the annular groove 5.

[0024] Connecting plates 32 are fixedly installed on both sides of the upper protective shell 31, and connecting plates 33 are fixedly installed on both sides of the lower protective shell 31. Insert plates 34 are fixedly installed at the bottom of the two connecting plates 32, and slots 35 are opened at the top of the two connecting plates 33. The insert plates 34 are inserted into the slots 35.

[0025] Both connecting plates 33 have snap-fit ​​components 4 for fixing insert plates 34 fixedly embedded on their outer walls. Specifically, the snap-fit ​​components 4 include two sleeves 41, each sleeve 41 has a sliding insert rod 42 inside, and each insert plate 34 has an insertion hole 43 on its outer wall that matches the insert rod 42. The insert rod 42 is inserted into the insertion hole 43, and the insert plate 34 is fixed by the insert rod 42. This not only improves the connection between the two protective shells 31, but also makes it convenient for workers to quickly disassemble the protective shells 31.

[0026] Next, a pull rod 44 is fixedly provided at the end of each of the two insertion rods 42 away from the insertion hole 43. A return spring 45 is sleeved on the outer wall of the pull rod 44. The two ends of the return spring 45 are fixed to the inner wall of the sleeve 41 and the insertion rod 42 respectively. One end of the pull rod 44 passes through the sleeve 41 and extends out of the outer wall of the sleeve 41.

[0027] To facilitate quick disassembly of the protective shell 31 by staff, pull plates 8 are provided on the outer sides of the two connecting plates 33. The pull plates 8 are fixed to the two pull rods 44. Two mounting holes 9 are opened on the outer walls of the two connecting plates 33. The two sleeves 41 are fixed in the two mounting holes 9 respectively to improve the stability of the sleeves 41.

[0028] In actual use, the operator first inserts the two protective shells 31 into the annular groove 5. When the two protective shells 31 are in contact, the insert plate 34 at the bottom of the connecting plate 1 32 is inserted into the slot 35. At the same time, the operator grasps the pull plate 8 and moves the two pull rods 44 and the two insert rods 42 connected to it together. The return spring 45 between the insert rod 42 and the sleeve 41 is compressed. When the insert plate 34 is inserted into place, the operator releases the pull plate 8. The insert rod 42 is automatically inserted into the insertion hole 43 under the elastic force of the return spring 45, which can firmly fix the insert plate 34 and the connecting plate 2 33 together, thereby fixing the two protective shells 31 together. This covers the outside of the multiple rubber tubes 2 to protect them and prevent the rubber tubes 2 from being damaged by objects during carrying and use. When sealing is required, the operator pulls the two pull plates 8 to move the insert rods 42 out of the insertion hole 43, which can loosen the two protective shells 31. After removing the two protective shells 31, the device body 1 can be used. At the same time, the protective shells 31 can be recycled and reused, thereby reducing costs and waste.

[0029] Refer to the instruction manual appendix Figures 1-5Multiple positioning rods 6 are fixedly provided on the inner walls of both protective shells 31. The inner wall of the annular groove 5 is machined with the same number of positioning holes 7 as the positioning rods 6. The positioning rods 6 are inserted into the positioning holes 7. The positioning rods 6 and the positioning holes 7 cooperate to facilitate the workers to accurately install the protective shells 31 into the annular groove 5.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
