Description

Technical Field

[0001] This invention relates to the field of aluminum alloy centralizers, and more specifically to a high-strength aluminum alloy centralizer. Background Technology

[0002] Aluminum alloy centralizers are key tools in oil drilling and completion operations, primarily used to center casing or tubing, ensuring uniform distribution of annular cement, improving cementing quality, and extending wellbore life. Traditional centralizers are often made of steel, which, while strong, is heavy, prone to corrosion, and increases running resistance and operating costs. With the increasing demand for lightweight designs, high-strength aluminum alloy centralizers are gradually becoming an important development direction.

[0003] Existing aluminum alloy centralizers typically employ a monolithic design, utilizing aerospace-grade aluminum alloy and formed through precision casting or CNC machining. Their core structure includes:

[0004] Spiral blade structure: The outer wall of the main body is provided with 3 to 6 spiral protruding blades. The cross-section of the blades is streamlined arc-shaped to reduce the drag during descent and enhance the rotational guiding ability.

[0005] Reinforcing ribs and hollow design: Longitudinal reinforcing ribs are often set between the blades to improve compressive strength, while hollow holes at the root of the blades reduce weight and promote mud flow;

[0006] End connection structure: Both ends are equipped with API standard threads or snap ring grooves for rigid connection with the tubing. Some designs add alloy steel inserts in the threaded area to improve torsional strength.

[0007] Surface strengthening treatment: The surface of the blades is often anodized or sprayed with a hard ceramic coating to enhance wear resistance and corrosion resistance.

[0008] The existing aluminum alloy centralizers have some shortcomings in use, as follows:

[0009] Existing aluminum alloy centralizers are installed by rigidly connecting to the tubing string using API standard threads or snap ring grooves at both ends. However, this connection method is time-consuming to install. Furthermore, due to variations in oil well diameter and casing diameter, different models of aluminum alloy centralizers are required to suit different application scenarios, making it difficult to standardize the size of the centralizers and thus inconvenient to use.

[0015] Furthermore, the flow guiding assembly includes a third positioning ring, an arc-shaped plate is fixedly connected to the outer side of the third positioning ring, a flow guiding strip is fixedly connected to the outer side of the arc-shaped plate, a third positioning bearing is fixedly connected to the top of the inner side of the flow guiding strip, an internally threaded sleeve is installed on the inner side of the third positioning bearing, and a threaded positioning sleeve is provided on the inner side of the internally threaded sleeve.

[0016] Furthermore, the clamping assembly includes a transmission clamping rod, a rotating shaft is fixedly connected to the bottom of the transmission clamping rod, a fourth positioning bearing box is installed on the outer side of the rotating shaft, a first positioning rod is fixedly connected to the bottom of the transmission clamping rod, a second positioning rod is fixedly connected to the bottom of the first positioning rod, a clamping post is fixedly connected to the top of the transmission clamping rod, and a clamping strip is fixedly connected to the outer side of the clamping post.

[0017] Furthermore, the height of the rotating notch is 1.5 times the height of the transmission teeth, the bottom of the rotating notch is on the same plane as the bottom of the transmission teeth, the thickness of the transmission teeth is the same as the thickness of the transmission gear, the bottom of the transmission teeth is on the same plane as the top of the transmission gear, the diameter of the lifting groove matches the diameter of the rotating rod, the cross-sectional dimensions of the sliding positioning block and the cross-sectional dimensions of the sliding limiting square groove are in clearance fit, the positioning thread matches the thread on the inner side of the threaded hole, and the teeth on the outer side of the transmission gear mesh with the transmission teeth.

[0018] Furthermore, the inner thread of the internal threaded sleeve and the outer thread of the threaded positioning sleeve are mutually engaged. The top and bottom of the flow guiding assembly are symmetrically provided with clamping and positioning components. The top of the threaded positioning sleeve is fixedly connected to the second positioning ring plate of the top clamping and positioning component, and the bottom of the threaded positioning sleeve is fixedly connected to the second positioning ring plate of the bottom clamping and positioning component. The outer diameter of the fourth positioning bearing box is mutually engaged with the diameter of the rotating positioning hole. The diameter of the first positioning rod is clearance-fitted with the width of the first waist-shaped groove, and the diameter of the second positioning rod is clearance-fitted with the width of the second waist-shaped groove.

[0019] The technical effects and advantages of this invention are as follows:

[0020] In this invention, when the equipment is installed onto centering sleeves of different diameters, rotating the rotating circular plate causes the rotating rod and positioning thread to rotate. The engagement between the positioning thread and the inner thread of the threaded hole causes the rotating circular plate, rotating rod, positioning thread, and sliding positioning block to rise. The interaction between the sliding positioning block and the sliding limiting square groove drives the rotating positioning shaft to rotate, which in turn drives the transmission gear to rotate. During the rising process of the rotating circular plate, rotating rod, positioning thread, and sliding positioning block, the second positioning bearing positions the rotating positioning shaft, causing the rotating circular plate, rotating rod, positioning thread, and sliding positioning block to slide and rise within the sliding limiting square groove and lifting groove. The rotation of the transmission gear drives the transmission teeth to rotate, thereby... Positioned by the first positioning bearing, the second positioning ring plate rotates counterclockwise relative to the first positioning ring plate. During the rotation of the second positioning ring plate, the positioning of the first and second positioning rods by the first and second waist-shaped grooves drives the transmission clamping rod to rotate relative to the first positioning rod, thereby causing the four clamping columns to spread out. During the rotation of the clamping assembly, the first and second positioning rods slide inside the first and second waist-shaped grooves. Finally, when the device is fitted onto the outside of the centering sleeve, a reverse rotation causes the four clamping columns to rotate towards the center of the first positioning ring plate to clamp the centering sleeve. This allows the device to be used with centering sleeves of different diameters and allows the device to adjust its positioning according to different centering sleeves, making it convenient for users.

[0021] This invention allows the internal threaded sleeve to rotate outside the threaded positioning sleeve when the equipment uses different drilling diameters. As the internal threaded sleeve continues to descend, the third positioning ring positions the arc-shaped plate, ensuring that the third positioning bearing remains vertical during the rotation of the internal threaded sleeve. Furthermore, as the internal threaded sleeve descends relative to the threaded positioning sleeve, the arc-shaped plate protrudes outward, adjusting the distance between the guide strip on the outer side of the arc-shaped plate and the inner side of the drilling well. This allows the equipment to be used with drilling wells of different diameters, broadening its applicability. Attached Figure Description

A transmission tooth 1024 is fixedly connected to the outer side of the second positioning ring plate 1021.

[0034] In a preferred embodiment, the adjusting assembly 103 includes a rotary positioning shaft 1031, a second positioning bearing 1032 is mounted on the top of the outer side of the rotary positioning shaft 1031, a transmission gear 1033 is fixedly connected to the bottom of the outer side of the rotary positioning shaft 1031, a lifting groove 1034 is provided at the bottom of the rotary positioning shaft 1031, a sliding limiting square groove 1035 is provided on the inner side of the lifting groove 1034, a rotating rod 1036 is provided on the inner side of the lifting groove 1034, a positioning thread 1037 is fixedly connected to the outer side of the rotating rod 1036 near the bottom, a rotating circular plate 1038 is fixedly connected to the bottom of the rotating rod 1036, and a sliding positioning block 1039 is fixedly connected to the top of the outer side of the rotating circular plate 1038.

[0035] In a preferred embodiment, the flow guiding assembly 2 includes a third positioning ring 201. An arc-shaped plate 202 is fixedly connected to the outer side of the third positioning ring 201. A flow guiding strip 203 is fixedly connected to the outer side of the arc-shaped plate 202. A third positioning bearing 204 is fixedly connected to the top of the inner side of the flow guiding strip 203. An internally threaded sleeve 205 is installed on the inner side of the third positioning bearing 204. A threaded positioning sleeve 206 is provided on the inner side of the internally threaded sleeve 205. When the equipment is installed onto centering sleeves of different diameters, rotating the rotating circular plate 1038 drives the rotating rod 1036 and the positioning thread 1037 to rotate. The engagement between the positioning thread 1037 and the inner thread of the threaded hole 1015 causes the rotating plate 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039 to rise. The engagement between the sliding positioning block 1039 and the sliding limiting square groove 1035 drives the rotating positioning shaft 1031 to rotate, which in turn drives the transmission gear 1033 to rotate. During the rising process of the rotating plate 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039, the second positioning bearing 1032 positions the rotating positioning shaft 1031, causing the rotating plate 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039 to rise. The moving circular plate 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039 slide and rise inside the sliding limiting square groove 1035 and the lifting groove 1034. 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, the first waist-shaped groove 1012 and the second waist-shaped groove 1013 position the first positioning rod 304 and the second positioning rod 305. The transmission clamping rod 301 rotates relative to the first positioning rod 304, causing the four clamping posts 306 to spread out. During the rotation of the clamping assembly 3, the first positioning rod 304 and the second positioning rod 305 slide inside the first waist-shaped groove 1012 and the second waist-shaped groove 1013. Finally, when the device is placed on the outside of the centering sleeve, the four clamping posts 306 can rotate towards the center of the first positioning ring plate 1011 to clamp the centering sleeve by rotating in the opposite direction. This allows the device to be used with centering sleeves of different diameters and to adjust the positioning according to different centering sleeves, making it convenient for users.

[0036] In a preferred embodiment, the clamping assembly 3 includes a transmission clamping rod 301, a rotating shaft 302 fixedly connected to the bottom of the transmission clamping rod 301, a fourth positioning bearing housing 303 mounted on the outer side of the rotating shaft 302, a first positioning rod 304 fixedly connected to the bottom of the transmission clamping rod 301, a second positioning rod 305 fixedly connected to the bottom of the first positioning rod 304, a clamping post 306 fixedly connected to the top of the transmission clamping rod 301, and a clamping strip 307 fixedly connected to the outer side of the clamping post 306. When the equipment uses different drilling diameters, the internal threaded sleeve 205 is rotated to... 205 rotates outside the threaded positioning sleeve 206. During the continuous descent of the internal threaded sleeve 205, due to the positioning of the arc plate 202 by the third positioning ring 201, the third positioning bearing 204 will remain in a vertical position during the rotation of the internal threaded sleeve 205. As the position of the internal threaded sleeve 205 relative to the threaded positioning sleeve 206 continues to descend, the arc plate 202 will protrude outward, thereby adjusting the distance between the guide strip 203 on the outer side of the arc plate 202 and the inner side of the well. This allows the equipment to be used for wells of different diameters, thus broadening its applicability.

[0037] In a preferred embodiment, the height of the rotating notch 1014 is 1.5 times the height of the transmission tooth 1024, the bottom of the rotating notch 1014 is on the same plane as the bottom of the transmission tooth 1024, the thickness of the transmission tooth 1024 is the same as the thickness of the transmission gear 1033, the bottom of the transmission tooth 1024 is on the same plane as the top of the transmission gear 1033, the diameter of the lifting groove 1034 matches the diameter of the rotating rod 1036, the cross-sectional dimensions of the sliding positioning block 1039 and the cross-sectional dimensions of the sliding limiting square groove 1035 are clearance-fitted, the positioning thread 1037 matches the thread on the inner side of the threaded hole 1015, and the teeth on the outer side of the transmission gear 1033 mesh with the transmission tooth 1024.

[0038] In a preferred embodiment, the inner thread of the internal threaded sleeve 205 engages with the outer thread of the threaded positioning sleeve 206. The top and bottom of the flow guiding component 2 are symmetrically provided with clamping and positioning components 1. The top of the threaded positioning sleeve 206 is fixedly connected to the second positioning ring plate 1021 of the top clamping and positioning component 1, and the bottom of the threaded positioning sleeve 206 is fixedly connected to the second positioning ring plate 1021 of the bottom clamping and positioning component 1. The outer diameter of the fourth positioning bearing box 303 engages with the diameter of the rotating positioning hole 1023. The diameter of the first positioning rod 304 is clearance-fitted with the width of the first waist-shaped groove 1012, and the diameter of the second positioning rod 305 is clearance-fitted with the width of the second waist-shaped groove 1013.

[0039] The working principle of this invention is as follows: When the equipment is installed onto a central sleeve of different diameters, rotating the rotating circular plate 1038 causes the rotating rod 1036 and the positioning thread 1037 to rotate. The engagement between the positioning thread 1037 and the inner thread of the threaded hole 1015 causes the rotating circular plate 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039 to rise. Furthermore, the interaction between the sliding positioning block 1039 and the sliding limiting square groove 1035 drives rotation. The positioning shaft 1031 rotates, which in turn drives the transmission gear 1033 to rotate. During the upward movement of the rotating disc 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039, the second positioning bearing 1032 positions the rotating positioning shaft 1031, causing the rotating disc 1038, rotating rod 1036, positioning thread 1037, and sliding positioning block 1039 to slide and rise within the sliding limit groove 1035 and lifting groove 1034. The transmission gear... During the rotation of 1033, the transmission gear 1024 rotates, and 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 positioning rod 304 and the second positioning rod 305 by the first waist-shaped groove 1012 and the second waist-shaped groove 1013, the transmission clamping rod 301 rotates relative to the first positioning rod 304, and then the four clamping columns 306 spread out. During the rotation of the clamping assembly 3, the first positioning rod 304 and the second positioning rod 305 slide on the inner side of the first waist-shaped groove 1012 and the second waist-shaped groove 1013. Finally, when the device is sleeved on the outside of the centering sleeve, the four clamping columns 306 can rotate towards the center of the first positioning ring plate 1011 to clamp the centering sleeve by rotating in the opposite direction. This allows the device to be used with centering sleeves of different diameters and allows the device to adjust the positioning according to different centering sleeves, making it convenient for users to use.

[0040] When the equipment uses different drilling diameters, the internal threaded sleeve 205 is rotated outside the threaded positioning sleeve 206. During the continuous descent of the internal threaded sleeve 205, the third positioning ring 201 positions the arc plate 202, so that the third positioning bearing 204 remains in a vertical position. As the position of the internal threaded sleeve 205 relative to the threaded positioning sleeve 206 continues to descend, the arc plate 202 protrudes outward, adjusting the distance between the outer guide strip 203 of the arc plate 202 and the inner side of the well. This allows the equipment to be used for drilling with different diameters, thus broadening its applicability.
