Description

Technical Field

[0001] This utility model relates to the technical field of water control screen tube sheath equipment, and in particular to a quick disassembly device for water control screen tube sheath. Background Technology

[0002] In well completion engineering for oil, gas, and geothermal wells, water control screen casings are a key sand and water control component, widely used in completion systems for complex well conditions such as horizontal and directional wells. Their main functions include protecting the screen casing itself, regulating the formation fluid inflow profile, and suppressing edge and bottom water inrush, thereby improving oil and gas recovery rates and extending the well's production cycle.

[0003] Due to the complex downhole environment, water control screen casings are prone to scaling, sand blockage, corrosion, or mechanical damage after long-term operation, requiring regular maintenance or replacement. Therefore, their disassembly and installation are crucial aspects of well completion and workover processes. Currently, the industry commonly uses traditional manual methods for disassembling and assembling water control screen casings. This involves using a hammer and pin to strike the casing or connecting parts point by point, loosening it through impact and vibration before removal. This method is not only inefficient and labor-intensive but also carries the risk of hand injuries.

[0004] Therefore, a quick-release device for the water control screen tube sheath is needed. Utility Model Content

[0005] To overcome the shortcomings of the existing technology that still generally adopts the traditional manual operation method for disassembling and assembling water control screen pipe sleeves, which involves using a hammer and a pin to strike the sleeve body or connecting parts point by point, and loosening it by impact vibration, this utility model provides a quick disassembly device for water control screen pipe sleeves.

[0006] The technical solution of this utility model is as follows: a quick disassembly device for a water control screen tube sheath, comprising an oil hammer, a semi-circular ring, a pin, meshing teeth, a screw, and a handle. Two screws are inserted into each of the two oil hammers, and a semi-circular ring is provided at the lower end of the two screws. The two semi-circular rings are connected by a pin. Two meshing teeth are provided on the inner wall of the semi-circular ring, and the meshing teeth correspond to the disassembly and assembly holes on the water control screen tube sheath. A handle is provided on the outer side of the oil hammer.

[0007] As a preferred technical solution of this utility model, it also includes a fixing block, a limiting ring, a lead screw and a screwing block. The fixing block is fixedly connected to the outside of the semi-circular ring, and the limiting ring is fixedly connected to the fixing block. The lead screw passes through both limiting rings, and two screwing blocks are screwed on the lead screw. The screwing blocks are in close contact with the limiting rings.

[0008] As a preferred technical solution of this utility model, it also includes a support plate, a buffer plate and a fixing nail. The support plate is installed on the outside of the oil hammer by the fixing nail, and the buffer plate is fixedly connected to the top of the support plate, and the buffer plate is in contact with the top of the oil hammer.

[0009] As a preferred technical solution of this utility model, it also includes an anti-slip sleeve, with the handle covered with an anti-slip sleeve.

[0010] As a preferred technical solution of this utility model, it also includes a friction ring, and a friction ring is provided on the inner side of the oil hammer.

[0011] As a preferred technical solution of this utility model, the inside of the oil hammer can be filled with counterweight material.

[0012] Compared with the prior art, this utility model provides a quick disassembly device for water control screen tube sleeve, which has the following beneficial effects: 1. By holding the handle, the oil hammer is pushed to slide along the screen tube axis to generate an impact force. The impact force is transmitted through the screw to the semi-circular ring, and then the meshing teeth act on the disassembly and assembly holes of the sleeve to form a downward knocking force, which drives the water control screen tube sleeve to move left and right, gradually loosening and removing the sleeve from the screen tube, realizing the quick disassembly and assembly of the sleeve. The operation is simple, convenient and fast.

[0013] 2. By rotating the two screw blocks, the two screw blocks move from both sides towards the middle, pushing the two limit rings to drive the corresponding semi-circular ring components to move closer to the center, thereby applying radial clamping force to the sheath and ensuring that the device will not loosen or shift during the striking process.

[0014] 3. The buffer plate can effectively absorb some vibration and noise, reduce the impact on the operator's arm, and protect the top of the hydraulic hammer from deformation and damage due to long-term impact. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] Example 1: A quick-release device for the sheath of a water control screen pipe, please refer to [link / reference]. Figures 1-5 The device includes two hydraulic hammers 1, two semicircular rings 2, two pins 3, two meshing teeth 4, two screws 5, and two handles 6. Two screws 5 are inserted into each of the two hydraulic hammers 1, and two semicircular rings 2 are set at the lower end of the two screws 5. The two semicircular rings 2 are connected by pins 3. Two meshing teeth 4 are set on the inner wall of the semicircular rings 2, and the meshing teeth 4 correspond to the disassembly and assembly holes on the water control screen sleeve. A handle 6 is set on the outside of the hydraulic hammers 1, and a non-slip sleeve 7 is fitted on the handle 6 to increase the comfort and safety of holding. A friction ring 8 is set on the inside of the hydraulic hammers 1, and the friction ring 8 is in close contact with the outer wall of the sleeve to provide additional friction and ensure that the device is firmly installed. The inside of the hydraulic hammers 1 can be filled with counterweight materials (such as lead pellets or iron sand). Users can flexibly adjust the weight of the hydraulic hammers 1 according to the actual impact force required, so that they can disassemble the tight sleeve without being too heavy to operate, thus realizing the adjustable impact force.

[0023] When this device is needed, the operator first removes the screws on the water control screen tube sleeve. Then, the two semicircular rings 2 fit around the outer wall of the water control screen tube sleeve and are connected by pins 3 to form a complete clamp. At this time, the meshing teeth 4 on the inner wall of the semicircular rings 2 will insert into the disassembly and assembly holes on the water control screen tube sleeve to achieve circumferential fixation and prevent slippage. After the device is fixed, the operator holds the handle 6 and pushes the oil hammer 1 to slide along the screen tube axis to generate impact force. The impact force passes through the screw 5 to the semicircular rings 2, and then the meshing teeth 4 act on the disassembly and assembly holes of the sleeve to form a downward striking force, which drives the water control screen tube sleeve to move left and right, gradually loosening and removing the sleeve from the screen tube, realizing the quick disassembly and assembly of the sleeve. The operation is simple, convenient and quick. After the sleeve is completely removed, open the semicircular rings 2 to remove the device from the sleeve.

[0024] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 4It also includes a fixing block 9, a limiting ring 10, a lead screw 11 and a screw block 12. The fixing block 9 is fixedly connected to the outside of the semi-circular ring 2. The limiting ring 10 is fixedly connected to the fixing block 9. The two limiting rings 10 pass through the lead screw 11 together. Two screw blocks 12 are screwed on the lead screw 11. The screw blocks 12 are in close contact with the limiting rings 10.

[0025] Before operation, by rotating the two screw blocks 12, the two screw blocks 12 are moved from the sides to the middle respectively, pushing the two limit rings 10 to drive the corresponding semi-circular ring 2 components to move closer to the center, thereby applying radial clamping force to the sheath and ensuring that the device will not loosen or shift during the striking process.

[0026] Please see Figure 1 and Figure 5 It also includes a support plate 13, a buffer plate 14 and a fixing nail 15. The support plate 13 is installed on the outside of the oil hammer 1 through the fixing nail 15. The buffer plate 14 is fixedly connected to the top of the support plate 13 and the buffer plate 14 is in contact with the top of the oil hammer 1.

[0027] When the top of the hydraulic hammer 1 is impacted, the buffer plate 14 can effectively absorb some of the vibration and noise, reduce the impact on the operator's arm, and protect the top of the hydraulic hammer 1 from deformation and damage due to long-term impact.
