Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a recyclable drill string stabilizer for a weld-overlay type SL-HF3500 high wear-resistant alloy column. Background Technology

[0002] Stabilizers, also known as centerers, are core tools used to stabilize downhole drilling tools and prevent well deviation. They are typically attached to the drill string near the larger diameter drill string and are primarily used to stabilize the drilling direction. They are crucial equipment in oil, gas, and geological exploration drilling projects to prevent well deviation changes. In existing technology, the problem of insufficient weld strength of the spiral wear-resistant strip in conventional drill string stabilizers has been effectively solved by brazing HF4000 alloy sheets to the outside of the spiral wear-resistant strip.

[0003] However, in the harsh working environment downhole, this structure still has obvious shortcomings: especially the cutting edge of the spiral belt facing downhole, which is the main stress surface during operation. Due to the poor wear resistance of the stabilizer body material, it is easily eroded and damaged after long-term scouring by the downhole medium, causing the exposed alloy column on the side to lose protection. In addition, the alloy column and the body are only slightly interference fit, and it is very easy to be washed away or broken after losing protection. This not only greatly shortens the service life of the stabilizer and causes it to be scrapped prematurely, but may also cause downhole accidents in severe cases. Therefore, in order to solve the above problems, a recyclable drill string stabilizer with a welded SL-HF3500 high wear-resistant alloy column is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a recyclable drill bit stabilizer for a weld-overlay type SL-HF3500 high wear-resistant alloy column, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an optional solution for the recyclable drill bit stabilizer of the weld overlay type SL-HF3500 high wear-resistant alloy column described in this invention, the recyclable drill bit stabilizer of the weld overlay type SL-HF3500 high wear-resistant alloy column includes a stabilizer, a spiral belt and a chip removal spiral groove. The outer side of the stabilizer is integrally formed with the spiral belt, and one end of the spiral belt is also provided with a replaceable wear-resistant part that fits on the outer side of the stabilizer; The spiral strips are arranged in multiple ways, and chip removal spiral grooves are opened between the spiral strips. The first SL-HF3500 cylindrical alloy blocks are evenly distributed inside one side of the spiral strip. The replaceable wear-resistant parts include a wear-resistant cover that is fitted on the outside of the stabilizer. Multiple docking blocks are integrally provided on the outside of the wear-resistant cover, and an arc-shaped part is integrally formed on one side of each docking block. The interior of both the mating block and the arc-shaped part is brazed with uniformly distributed second SL-HF3500 cylindrical alloy blocks. The outer side of the wear-resistant cover is provided with positioning holes, and positioning bolts are installed inside the positioning holes. The positioning bolts pass through the positioning holes and are fixedly connected to the stabilizer. The wear-resistant cover is fixedly connected with alternating positioning blocks and positioning elements arranged in a circular trajectory, and the positioning elements are all inserted into the spiral belt.

[0006] As an optional embodiment of the recyclable drill bit stabilizer of the weld overlay type SL-HF3500 high wear-resistant alloy column described in this invention, wherein: the ends of the first SL-HF3500 cylindrical alloy block and the second SL-HF3500 cylindrical alloy block away from the stabilizer are both arranged with arc surfaces.

[0007] As an optional solution for the recyclable drill stabilizer of the SL-HF3500 high wear-resistant alloy column of the present invention, the positioning block is arranged in the form of a 1 / 2 disc and is convex, and the positioning block is embedded in the groove where the chip removal spiral groove is located.

[0008] As an optional embodiment of the recyclable drill stabilizer for the weld overlay type SL-HF3500 high wear-resistant alloy column described in this invention, wherein the surface of the arc-shaped part is set as an arc surface.

[0009] Stabilizers, also known as centerers, are core tools used to stabilize downhole drilling tools and prevent well deviation. They are typically attached to the drill string near the larger diameter drill string and are primarily used to stabilize the drilling direction. They are crucial equipment in oil, gas, and geological exploration drilling projects to prevent well deviation changes. Current technology has effectively solved the problem of insufficient weld strength of the spiral wear-resistant strip in conventional drill string stabilizers by brazing HF4000 alloy sheets to the outside of the spiral wear-resistant strip. However, in the harsh working environment of downholes, this structure still has significant shortcomings: especially the cutting edge of the spiral strip facing downhole, which is the main stress surface during operation. Due to the poor wear resistance of the stabilizer body material, it is easily eroded and damaged by long-term exposure to downhole media, causing the exposed alloy column on the side to lose its protection. Furthermore, the alloy column is only slightly press-fitted to the body, making it extremely easy to be washed away or broken after losing protection. This not only significantly shortens the stabilizer's service life and leads to premature failure, but in severe cases, it may even cause downhole accidents.

[0010] To address the aforementioned issues, performance optimization was achieved through targeted structural improvements, specifically as follows: A second SL-HF3500 cylindrical alloy block is installed on the arc-shaped portion outside the wear-resistant cover and inside the docking block. This alloy block effectively supports the stress-bearing surface, ensuring the normal operation of the stabilizer. Simultaneously, the ends of both the first and second SL-HF3500 cylindrical alloy blocks feature an arc-shaped design, resulting in lower stress compared to a square structure. This design reduces the likelihood of tearing and allows for the filling of alloy powder with a higher tungsten carbide content, improving wear resistance and reducing frictional resistance when in contact with the wellbore. Tungsten carbide powder is used to fill the welding process between the second SL-HF3500 cylindrical alloy block and the wear-resistant cover and docking block. Since these areas are the core stress-bearing surfaces during downhole operation and the primary areas where the stabilizer fails, this significantly enhances the erosion resistance of the wear-resistant zone and effectively extends the stabilizer's service life.

[0011] In addition, the stress-bearing surface adopts a replaceable structural design: when the mating block and the surface of the arc-shaped part are severely worn, the replaceable wear-resistant parts can be directly replaced without replacing the entire stabilizer, which significantly reduces the cost of equipment use.

[0012] As an optional solution for the recyclable drill stabilizer of the SL-HF3500 high wear-resistant alloy column with overlay welding as described in this invention, the positioning component includes a positioning frame integrally formed with the wear-resistant cover, and each positioning frame has a detection groove inside. Each detection groove has a control module inside, and each control module has a temperature detector for detecting the temperature of the arc-shaped part and a vibration detector for detecting the vibration of the arc-shaped part installed on one side.

[0013] As an optional solution for the recyclable drill stabilizer of the SL-HF3500 high wear-resistant alloy column with overlay welding as described in this invention, a sealing gasket is provided above the control module, and the outer side of the sealing gasket is in contact with the inner wall of the detection groove.

[0014] As an optional solution for the recyclable drill stabilizer of the SL-HF3500 high wear-resistant alloy column with overlay welding as described in this invention, heat exchange grooves are provided on both sides of the groove where the chip removal spiral groove is located, and the heat exchange grooves are provided on both sides of the positioning member.

[0015] During the installation of the wear-resistant cover, its positioning frame is inserted into the spiral belt. Through the cooperation of the positioning frame and the positioning block, the wear-resistant cover is accurately positioned. During use, the positioning frame is also equipped with a control module, a temperature detector and a vibration detector, which can monitor the operating status of one end of the wear-resistant cover in real time and provide data support for subsequent control. After installation, heat exchange grooves are provided on both sides of the spiral belt. During the slag and chip removal process, the slurry is discharged through the chip removal spiral groove and the heat exchange groove, which not only removes some of the heat generated during the operation, but also, because the heat exchange grooves are located on both sides of the positioning components inside the spiral belt, they can play a heat exchange role on the positioning components, ensuring the stable and normal operation of their internal components.

[0016] Compared with the prior art, the beneficial effects of the present invention are: A second SL-HF3500 cylindrical alloy block is installed on the arc-shaped part on the outside of the wear-resistant cover and inside the docking block. This alloy block effectively supports the stress surface and ensures the normal operation of the stabilizer. At the same time, the ends of the first and second SL-HF3500 cylindrical alloy blocks are designed with arc-shaped surfaces. Compared with the square structure, it has less stress, is less prone to tearing, and can be filled with alloy powder with higher tungsten carbide content, which not only improves the wear resistance coefficient, but also reduces the frictional resistance when in contact with the well wall.

[0017] During the welding process of the second SL-HF3500 cylindrical alloy block with the wear-resistant cover and the docking block, tungsten carbide powder is filled in. Since these parts are the core stress surfaces during downhole operations and the main areas where stabilizers fail, this measure can significantly improve the erosion resistance of the wear-resistant belt and effectively extend the service life of the stabilizer.

[0018] In addition, the stress-bearing surface adopts a replaceable structural design: when the mating block and the surface of the arc-shaped part are severely worn, the replaceable wear-resistant parts can be directly replaced without replacing the entire stabilizer, which significantly reduces the cost of equipment use.

[0019] During the installation of the wear-resistant cover, its positioning frame is inserted into the spiral belt. Through the cooperation of the positioning frame and the positioning block, the wear-resistant cover is accurately positioned. During use, the positioning frame is also equipped with a control module, a temperature detector and a vibration detector, which can monitor the operating status of one end of the wear-resistant cover in real time and provide data support for subsequent control.

[0020] After installation, heat exchange grooves are provided on both sides of the spiral belt. During the slag and chip removal process, the slurry is discharged through the chip removal spiral groove and the heat exchange groove, which not only removes some of the heat generated during the operation, but also, because the heat exchange grooves are located on both sides of the positioning components inside the spiral belt, they can play a heat exchange role on the positioning components, ensuring the stable and normal operation of their internal components.

[0023] Example 1: Please refer to Figure 1 and Figure 2 The present invention provides a technical solution: A recyclable drill bit stabilizer for a weld overlay type SL-HF3500 high wear-resistant alloy column includes a stabilizer 1, a spiral belt 2, and a chip removal spiral groove 5; The outer side of the stabilizer 1 is integrally formed with the spiral belt 2, and one end of the spiral belt 2 is also provided with a replaceable wear-resistant part 4 that is sleeved on the outer side of the stabilizer 1; Multiple spiral strips 2 are arranged, and chip removal spiral grooves 5 are opened between each spiral strip 2. A first SL-HF3500 cylindrical alloy block 3 is uniformly distributed inside one side of the spiral strip 2. The replaceable wear-resistant part 4 includes a wear-resistant cover 401 that is sleeved on the outside of the stabilizer 1. Multiple docking blocks 408 are integrally provided on the outside of the wear-resistant cover 401, and an arc-shaped part 402 is integrally formed on one side of the docking block 408. Both the mating block 408 and the arc-shaped part 402 are brazed with uniformly distributed second SL-HF3500 cylindrical alloy blocks 403 inside; The outer side of the wear-resistant cover 401 is provided with positioning holes 406, and positioning bolts 407 are provided inside the positioning holes 406. The positioning bolts 407 pass through the positioning holes 406 and are fixedly connected to the stabilizer 1. The wear-resistant cover 401 is fixedly connected with alternating positioning blocks 404 and positioning elements 405 arranged in a circular trajectory, and the positioning elements 405 are all inserted into the spiral belt 2.

[0024] The first SL-HF3500 cylindrical alloy block 3 and the second SL-HF3500 cylindrical alloy block 403 are both arranged with an arc surface at the end away from the stabilizer 1.

[0025] The positioning block 404 is arranged in the shape of a half-circle and is convex. The positioning block 404 is embedded in the groove where the chip removal spiral groove 5 is located.

[0026] The surface of the arc-shaped part 402 is set as an arc.

[0027] Stabilizers, also known as centerers, are core tools used to stabilize downhole drilling tools and prevent well deviation. They are typically attached to the drill string near the larger diameter drill string and are primarily used to stabilize the drilling direction. They are crucial equipment in oil, gas, and geological exploration drilling projects to prevent well deviation changes. Current technology has effectively solved the problem of insufficient weld strength of the spiral wear-resistant strip in conventional drill tool stabilizers by brazing HF4000 alloy sheets to the outside of the spiral wear-resistant strip. However, in the harsh working environment of downholes, this structure still has significant shortcomings: especially the cutting edge of the spiral strip facing downhole, which is the main stress surface during operation. Due to the poor wear resistance of the stabilizer body material, it is easily eroded and damaged by long-term exposure to downhole media, causing the exposed alloy column on the side to lose its protection. Furthermore, the alloy column is only slightly press-fitted to the body, making it extremely easy to be washed away or broken after losing protection. This not only significantly shortens the stabilizer's service life, leading to premature failure, but may also cause downhole accidents in severe cases. To address these issues… Performance optimization was achieved through targeted structural improvements, specifically as follows: A second SL-HF3500 cylindrical alloy block 403 is installed inside the arc-shaped part 402 on the outside of the wear-resistant cover 401 and inside the docking block 408. It can be fixed by welding. The alloy block effectively supports the stress surface and ensures the normal operation of the stabilizer 1. At the same time, the ends of the first SL-HF3500 cylindrical alloy block 3 and the second SL-HF3500 cylindrical alloy block 403 are designed with arc surfaces. Compared with the square structure, the stress is smaller and it is not easy to be torn. It can also be filled with alloy powder with higher tungsten carbide content, which not only improves the wear resistance coefficient, but also reduces the frictional resistance when in contact with the well wall. During the welding process of the second SL-HF3500 cylindrical alloy block 403 with the wear-resistant cover 401 and the docking block 408, tungsten carbide powder is filled in. Since these parts are the core stress surfaces during downhole operations and the main areas where stabilizers fail, this measure can significantly improve the erosion resistance of the wear-resistant belt and effectively extend the service life of the stabilizer.

[0028] In addition, the stress-bearing surface adopts a replaceable structural design: when the surfaces of the docking block 408 and the arc-shaped part 402 are severely worn, the replaceable wear-resistant part 4 can be directly replaced without replacing the entire stabilizer 1, which significantly reduces the equipment operating cost. The first SL-HF3500 cylindrical alloy block 3 is also brazed to the side of the spiral belt 2 to increase the side strength. The second SL-HF3500 cylindrical alloy block 403 is also set on the side of the mating block 408 to increase the overall strength of the wear-resistant cover 401.

[0029] Also includes the following: When the arc-shaped part 402 contacts the inside of the well wall, its arc surface can serve as a guide to ensure the smooth descent of the device. The second SL-HF3500 cylindrical alloy block 403 can reinforce the docking block 408 and the arc-shaped part 402. At the same time, one end of the second SL-HF3500 cylindrical alloy block 403 is set with an arc surface, so that the arc surface forms a smooth sliding contact with the well wall, which greatly reduces the cutting effect of the cylindrical alloy block on the well wall and greatly reduces the contact area between the stabilizer 1 and the well wall. Thus, the frictional resistance between the stabilizer 1 and the well wall is greatly reduced, thereby ensuring the drill bit speed and drilling efficiency. Secondly, when the second SL-HF3500 cylindrical alloy block 403 is welded to the wear-resistant cover 401, tungsten carbide powder is used as filler, because these parts are the stress surfaces during downhole operations and the main parts where the stabilizer fails. This greatly improves the wear-resistant belt's resistance to erosion and extends its service life. When installing the wear-resistant cover 401, the positioning block 404 is inserted into the arc-shaped groove at the bottom of the chip removal spiral groove 5 between the spiral belts 2 to serve as a positioning tool. At the same time, the positioning part 405 is inserted into the spiral belt 2 to reinforce the replaceable wear-resistant part 4 and prevent it from becoming dislodged or misaligned during use.

[0030] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 Specifically, the positioning component 405 includes a positioning frame 4051 integrally formed with the wear-resistant cover 401, and each positioning frame 4051 has a detection groove 4052 inside. Each detection groove 4052 has a control module 4053 inside, and each control module 4053 has a temperature detector 4054 for detecting the temperature of the arc-shaped part 402 and a vibration detector 4055 for detecting the vibration of the arc-shaped part 402 installed on one side.

[0031] A sealing gasket 4056 is provided above each control module 4053, and the outer side of the sealing gasket 4056 is in contact with the inner wall of the detection groove 4052.

[0032] Heat exchange grooves 6 are provided on both sides of the groove body where the chip removal spiral groove 5 is located, and the heat exchange grooves 6 are provided on both sides of the positioning member 405.

[0033] During the installation of the wear-resistant cover 401, its positioning frame 4051 is inserted into the spiral belt 2. Through the cooperation of the positioning frame 4051 and the positioning block 404, the wear-resistant cover 401 is accurately positioned. During use, the positioning frame 4051 is also equipped with a control module 4053, a temperature detector 4054 and a vibration detector 4055, which can monitor the operating status of one end of the wear-resistant cover 401 in real time and provide data support for subsequent control.

[0034] After installation, heat exchange grooves 6 are provided on both sides of the spiral belt 2. During the slag and chip removal process, the slurry is discharged through the chip removal spiral groove 5 and the heat exchange groove 6, which can not only remove some of the heat generated during the operation, but also, since the heat exchange grooves 6 are correspondingly set on both sides of the positioning component 405 inside the spiral belt 2, they can play a heat exchange role on the positioning component 405, ensuring the stable and normal operation of its internal components; Also includes the following: During the installation of the wear-resistant cover 401, its positioning frame 4051 is inserted into the spiral belt 2. Through the cooperation of the positioning frame 4051 and the positioning block 404, the wear-resistant cover 401 is accurately positioned. During use, the positioning frame 4051 is also equipped with a control module 4053, a temperature detector 4054 and a vibration detector 4055. The detection ends of the temperature detector 4054 and the vibration detector 4055 are in close contact with one side of the wear-resistant cover 401, which can monitor the contact status between the wear-resistant cover 401 and objects such as rocks in the well in real time.

[0035] In the event of overheating, abnormal vibration, or other issues, the signal transmission unit inside the control module 4053 will promptly issue an alarm signal, allowing staff to immediately grasp the situation on-site and carry out subsequent handling operations.

[0036] When the wear-resistant cover 401 is installed inside the spiral belt 2, the chip removal spiral groove 5 is used for the flow and discharge of slurry, which can reduce the frictional resistance during equipment operation and help reduce the operating temperature. At the same time, heat exchange grooves 6 are provided on both sides of the spiral belt 2, and some slurry can flow through the heat exchange grooves 6. The wear-resistant cover 401 is located on one side of the heat exchange groove 6, and can play an auxiliary heat exchange role for the internal components of the wear-resistant cover 401 with the help of the slurry flow. In addition, the sealing gasket 4056 can effectively seal the control module 4053 inside the wear-resistant cover 401 to prevent external liquid from seeping in and causing device failure and inability to operate normally.
