Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy centralizers, and more particularly to a high-strength aluminum alloy centralizer. Background Art

[0002] Aluminum alloy centralizers are key tools in oil drilling and well completion operations, mainly used to center the casing or pipe string, ensure uniform distribution of annular cement, improve cementing quality and extend wellbore life. Traditional centralizers often use steel materials, which have high strength but are heavy and prone to corrosion, increasing the running resistance and operation cost. With the increasing demand for lightweight, high-strength aluminum alloy centralizers have gradually become an important development direction.

[0003] The main structure of existing aluminum alloy centralizers usually adopts an integral design, selects aerospace-grade aluminum alloy, and is formed by precision casting or CNC machining. Its core structure includes: Spiral fin structure: There are 3 - 6 spiral raised fins on the outer wall of the main body, and the cross-section of the fins is a streamline arc to reduce the running resistance and enhance the rotary steering ability; Reinforcing rib and hollow design: Longitudinal reinforcing ribs are often arranged between the fins to improve the compressive strength. At the same time, the weight is reduced and mud flow is promoted through the hollow holes at the roots of the fins; End connection structure: API standard threads or circlip grooves are configured at both ends to rigidly connect with the pipe string, and some designs add alloy steel inserts in the threaded area to improve the torsional strength; Surface strengthening treatment: The surfaces of the fins are mostly anodized or sprayed with a hard ceramic coating to enhance wear resistance and corrosion resistance.

[0004] There are some deficiencies in the use of existing aluminum alloy centralizers, which are specifically as follows: When installing existing aluminum alloy centralizers, they are rigidly connected to the pipe string through API standard threads or circlip grooves configured at both ends. However, this connection method takes a lot of time during installation. Moreover, during the use of existing aluminum alloy centralizers, according to the actual oil production rate of the oil well, the diameters of the oil well and the centered casing are different. Different models of existing aluminum alloy centralizers are required to adapt to different application scenarios, making the aluminum alloy centralizers unable to have a unified size, and thus it is not convenient to use.

During the continuous descent of the internal thread casing, due to the positioning of the third positioning ring on the arc-shaped plate, when the internal thread casing rotates, the third positioning bearing will remain stationary in the vertical position. And during the continuous descent of the position of the internal thread casing relative to the thread positioning casing, the arc-shaped plate will protrude outward, adjusting the distance between the diversion strip on the outside of the arc-shaped plate and the inside of the drilling, enabling the device to be applicable to drillings with different diameters and expanding the applicable range of the device.

During the rotation of the transmission gear 1033, the transmission teeth 1024 are driven to rotate. Then, under the positioning of the first positioning bearing 1022, the second positioning ring plate 1021 rotates counterclockwise relative to the first positioning ring plate 1011. During the rotation of the second positioning ring plate 1021, due to the positioning of the first waist-shaped groove 1012 and the second waist-shaped groove 1013 on the first positioning rod 304 and the second positioning rod 305, the transmission clamping rod 301 is driven to rotate relative to the first positioning rod 304, and then the four clamping columns 306 spread. During the rotation of the clamping assembly 3, the first positioning rod 304 and the second positioning rod 305 will slide inside the first waist-shaped groove 1012 and the second waist-shaped groove 1013. Finally, when the device is sleeved outside the centering sleeve, by rotating in the reverse direction, the four clamping columns 306 can be rotated towards the center of the first positioning ring plate 1011 to clamp the centering sleeve, enabling the device to be applicable to centering sleeves with different diameters, enabling the device to adjust the positioning according to different centering sleeves, and facilitating the use of the user; When the device uses different drilling diameters, by rotating the internal thread sleeve 205, the internal thread sleeve 205 rotates outside the threaded positioning sleeve 206. During the continuous descent of the internal thread sleeve 205, due to the positioning of the third positioning ring 201 on the arc-shaped plate 202, when the internal thread sleeve 205 rotates, the third positioning bearing 204 will remain in a vertical position without moving. And during the continuous descent of the position of the internal thread sleeve 205 relative to the threaded positioning sleeve 206, the arc-shaped plate 202 will protrude outward, adjusting the distance between the guide strips 203 on the outer side of the arc-shaped plate 202 and the inside of the drilling, enabling the device to be applicable to drillings with different diameters and making the application range of the device wider.
