Description

Technical Field

[0001] This invention relates to the field of oil drilling technology, and in particular to a magnetically driven wellbore cleaning and shock device. Background Technology

[0002] In oil and gas drilling operations, inadequate wellbore cleaning easily leads to drill string sticking, a core problem restricting drilling efficiency and safety. Traditionally, downhole cleaning tools and shovel tools are used alternately for this purpose. However, conventional cleaning tools rely on mechanical dynamic seals to transmit power, which are prone to wear and failure in the high-temperature, high-pressure, and highly abrasive formation environment downhole, leading to drilling fluid leakage and shortened tool life. Furthermore, existing shovels and cleaning tools are functionally separate; once sticking occurs, the drill string must be pulled out and replaced, resulting in long downtime and high costs. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in related technologies. To this end, this invention provides a magnetically driven wellbore cleaning and tremor device, which solves the technical problem of difficult cuttings removal in the wellbore in the prior art. This wellbore cleaning and tremor device can simultaneously complete cuttings cleaning and tremor-assisted unblocking operations, improving drilling efficiency.

[0004] This invention provides a magnetically driven wellbore cleaning and vibration device, comprising: The mandrel is divided into a first core segment, a second core segment, and a third core segment along the axial direction. A first limiting ring is provided between the first core segment and the second core segment, and a second limiting ring is provided between the second core segment and the third core segment. A plurality of stators are fitted onto the first core segment, and a rotor is rotatably connected to each of the stators. The plurality of rotors are connected to a rotor housing, and the rotors are provided with guide vanes. A first connecting cylinder is inserted into the rotor housing. A rotating bearing is provided on the outer wall of the first connecting cylinder at the position corresponding to the second core segment. A cleaning blade is connected to the rotating bearing. A first magnetic element is provided in the second core segment. The cleaning blade has a second magnetic element. The vibration assembly installed in the third core segment has a shock block provided on the inner wall of the first connecting cylinder corresponding to the position of the vibration assembly. The fluid in the well flows through the guide vanes to drive the rotor to rotate, thereby driving the stator and the spindle to rotate, which in turn drives the vibration assembly to reciprocate up and down, causing the vibration assembly to vibrate the shock block. At the same time, the spindle rotates, and the first and second magnetic components drive the cleaning blades to rotate through magnetic force.

[0005] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that the first core segment is provided with a first limiting strip along the axial direction, and the stator is provided with a first connecting port corresponding to the first limiting strip, and is connected to the first limiting strip through the first connecting port to connect the stator and the first core segment.

[0006] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that the third core segment is provided with a threaded section; The vibration assembly includes an impact member screwed to the threaded section, a first pressure block connected to the top of the impact member, and a second pressure block connected to the bottom of the impact member. A limit block is provided at the position below the impact member of the first connecting cylinder. The second pressure block and the limit block are connected by a plurality of first springs. The first pressure block is located above the vibration block. The impact component includes a first impact block and a second impact block whose sides can be fitted together. The first impact block and the second impact block can be screwed together to the threaded section. The first impact block and the second impact block are connected by a plurality of second springs. The first pressure block is connected to the top of the first impact block and abuts against the top of the second impact block. The second pressure block is connected to the bottom of the first impact block and abuts against the top of the second impact block. The rotation of the spindle causes the first and second impact blocks to move downwards, thereby compressing the first spring with the second pressure block. After the second impact block moves downwards, it disengages from the shock block, and the second spring resets, causing the second and first impact blocks to pop out away from the spindle. Then the first spring resets, pushing the second pressure block, the first pressure block, the first impact block, and the second impact block upwards, causing the first and second impact blocks to strike the shock block and move between the shock blocks, compressing the second spring, and causing the first and second impact blocks to fit together and be screwed into the threaded section.

[0007] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that the impact member is formed with an inclined first impact surface, and the vibration block is formed with a second impact surface corresponding to the first impact surface.

[0008] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that the bottom surface of the second pressure block is formed with an installation groove, the top surface of the limiting block is provided with an installation hole, and the bottom end of the first spring is provided in the installation hole and the top end is provided in the installation groove.

[0009] A further improvement of the magnetically driven wellbore cleaning and impact device of the present invention is that a third magnetic element is provided on the side of the impact member, a second connecting cylinder is sleeved on the outside of the first connecting cylinder, a fourth magnetic element is provided between the first connecting cylinder and the second connecting cylinder, and the top of the second connecting cylinder is attached to the rotating bearing located at the bottom; by moving the first impact block and the second impact block upward, the third magnetic element is driven to move upward, and under the action of magnetic force, the fourth magnetic element can be driven to move upward, thereby the fourth magnetic element strikes the rotating bearing.

[0010] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that a reinforcing ring is formed at the bottom of the inner sidewall of the second connecting cylinder.

[0011] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that the vibration component is provided in two sets, with the limiting block corresponding to the top vibration component and the inner wall of the first connecting cylinder being fixedly connected, and the limiting block corresponding to the bottom vibration component and the inner wall of the first connecting cylinder being detachably connected.

[0012] A further improvement of the magnetically driven wellbore cleaning and vibration device of the present invention is that the bottom of the rotor housing is tapered inward to form a sleeve section, and the first connecting cylinder is sleeved on the sleeve section.

[0013] A further improvement of the magnetically driven wellbore cleaning and tremor device of the present invention is that the cleaning blades are formed with spiral-shaped fluid guiding strips.

[0014] This invention discloses a magnetically driven wellbore cleaning and impact device. The cleaning blades utilize a non-contact magnetic transmission method, eliminating the traditional rotary dynamic seal mechanism. This solves the problem of wear and failure of mechanical seals caused by high temperature, high pressure, and abrasive media in downhole environments, significantly improving the tool's operational reliability under harsh conditions, extending its service life, and reducing operational risks and costs due to tool failure. The up-and-down movement of the vibration component continuously vibrates the impact block, thereby vibrating the first connecting cylinder and dislodging impurities adhering to the wellbore cleaning and impact device, improving its operational stability. The interaction between the first and second magnetic components facilitates the rotation of the cleaning blades, enabling them to stably clean the wellbore wall. The upward movement of the first and second impact blocks drives the third magnetic component upward, which in turn drives the fourth magnetic component upward, causing it to strike the rotating bearing and complete the impact action.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The following embodiments are used to illustrate this invention but should not be used to limit the scope of this invention.

[0029] The following is combined Figures 1 to 10 The present invention describes a magnetically driven wellbore cleaning and vibration device, comprising: The mandrel 1 is divided into a first core segment 101, a second core segment 102, and a third core segment 103 along the axial direction. A first limiting ring 106 is provided between the first core segment 101 and the second core segment 102, and a second limiting ring 107 is provided between the second core segment 102 and the third core segment 103. A plurality of stators 2 are fitted onto the first core segment 101, and a rotor 3 is rotatably connected to each of the stators 2. The plurality of rotors 3 are connected to a rotor housing 4, and the rotor 3 is provided with guide vanes. A first connecting cylinder 7 is inserted into the rotor housing 4. A rotating bearing 5 is provided on the outer wall of the first connecting cylinder 7 at the position corresponding to the second core segment 102. A cleaning blade 8 is connected to the rotating bearing 5. A first magnetic element 6 is provided on the second core segment 102. The cleaning blade 8 has a second magnetic element. The vibration assembly installed on the third core segment 103 has a vibration block 701 provided on the inner wall of the first connecting cylinder 7 corresponding to the position of the vibration assembly. The fluid in the well flows through the guide vane to drive the rotor 3 to rotate, thereby driving the stator 2 and the spindle 1 to rotate, which in turn drives the vibration assembly to reciprocate up and down, causing the vibration assembly to vibrate the shock block 701. At the same time, the spindle 1 rotates, and the first magnetic element 6 and the second magnetic element drive the cleaning blade 8 to rotate through magnetic force.

[0030] Preferably, the guide vanes are inclined spirals. Due to the special design of the guide vanes, the fluid generates power during its flow, which drives the rotor 3 to rotate. Simultaneously, the rotor 3 rotates, causing the stator 2, which is connected to it, to rotate as well. Since the stator 2 is mounted on the first core segment 101 of the mandrel 1, the rotation of the stator 2 further drives the mandrel 1 to rotate. The first magnetic element 6 on the second core segment 102 and the second magnetic element on the cleaning blade 8 attract or repel each other through magnetic force. This effect drives the cleaning blade 8 to rotate, effectively cleaning the wellbore. Simultaneously, the vibration assembly installed on the third core segment 103 reciprocates up and down with the rotation of the mandrel 1. During this movement, the vibration assembly continuously vibrates the shock block 701 on the inner wall of the first connecting cylinder 7 at its corresponding position. The vibration of the shock block 701 further enhances the cleaning effect, dislodging or loosening difficult-to-clean rock debris in the wellbore, making it easier to remove. The entire device is driven by the fluid inside the well, which enables the rotor 3 to rotate, the spindle 1 to rotate, the cleaning blades 8 to rotate, and the vibration components to vibrate. The synergistic effect of these actions allows the wellbore cleaning and vibration device to efficiently clean the wellbore, improving the efficiency and safety of downhole operations.

[0031] In a preferred embodiment of the magnetically driven wellbore cleaning and vibration device of the present invention, such as... Figure 1 , Figure 2 and Figure 4 As shown, the first core segment 101 is provided with a first limiting strip 105 along the axial direction, and the stator 2 is provided with a first connecting port corresponding to the first limiting strip 105. The stator 2 is connected to the first limiting strip 105 through the first connecting port to connect the stator 2 and the first core segment 101.

[0032] Preferably, the connection between the first limiting strip 105 and the first connecting port improves the connection stability between the stator 2 and the first core segment 101, ensures the reliability of the connection between the stator 2 and the first core segment 101, and can effectively ensure that the spindle 1 can rotate stably.

[0033] Furthermore, such as Figures 1 to 10 As shown, the third core segment 103 is provided with a threaded segment 104; The vibration assembly includes an impact member 12 screwed to the threaded section 104, a first pressure block 15 connected to the top of the impact member 12, and a second pressure block 14 connected to the bottom of the impact member 12. A limit block 11 is provided at the position below the impact member 12. The second pressure block 14 and the limit block 11 are connected by a plurality of first springs 16. The first pressure block 15 is located above the vibration block 701. The impact member 12 includes a first impact block and a second impact block that can be fitted together on the sides. The first impact block and the second impact block can be screwed together on the threaded section 104. The first impact block and the second impact block are connected by a plurality of second springs. The first pressure block 15 is connected to the top of the first impact block and abuts against the top of the second impact block. The second pressure block 14 is connected to the bottom of the first impact block and abuts against the top of the second impact block. The rotation of the spindle 1 causes the first impact block and the second impact block to move downward, thereby causing the second pressure block 14 to compress the first spring 16. After the second impact block moves downward, it disengages from the shock block 701, thereby resetting the second spring so that the second impact block and the first impact block pop out in a direction away from the spindle 1. Then the first spring 16 resets to push the second pressure block 14, the first pressure block 15, the first impact block and the second impact block upward, so that the first impact block and the second impact block strike the shock block 701 and move between the shock blocks 701, causing the second spring to compress, so that the first impact block and the second impact block fit together and are screwed together on the threaded section 104.

[0034] Preferably, both the first spring 16 and the second spring are made of high-strength, corrosion-resistant spring steel to ensure stable operation for a long time in the complex and harsh environment downhole and to prevent damage.

[0035] Specifically, the vibration assembly is provided in two sets: the limiting block 11 of the vibration assembly located at the top is fixedly connected to the inner wall of the first connecting cylinder 7, and the limiting block 11 of the vibration assembly located at the bottom is detachably connected to the inner wall of the first connecting cylinder 7.

[0036] Preferably, the shock block 701 has a first flow channel for the well fluid to flow through, and the limiting block 11 has a second flow channel for the well fluid to flow through. So when the vibration component is located between the shock blocks 701, the well fluid can pass smoothly through the first flow channel, and when the vibration component compresses the first spring 16, the well fluid can pass smoothly through the second flow channel.

[0037] Preferably, the maximum outer diameter of the first pressure block 15 is greater than the minimum inner diameter of the impact block 701, thereby preventing the vibration assembly from detaching from the mandrel 1. The maximum outer diameter of the second pressure block 14 is greater than the minimum inner diameter of the limiting block 11, thereby preventing the vibration assembly from detaching from the mandrel 1. This allows the vibration assembly to reciprocate stably between the corresponding impact block 701 and the limiting block 11, thus facilitating the stable impact of the vibration assembly on the impact block 701 and improving the cleaning effect inside the well.

[0038] Specifically, the impact member 12 is formed with an inclined first impact surface 1201, and the shock block 701 is formed with a second impact surface corresponding to the first impact surface 1201, thereby ensuring that the impact member 12 can stably impact the shock block 701, and that the first impact block and the second impact block can be stably restricted by the shock block 701 and then re-adhere together.

[0039] Preferably, the first impact block and the second impact block are connected by four second springs.

[0040] Specifically, the bottom surface of the second pressure block 14 has a mounting groove, the top surface of the limiting block 11 has a mounting hole, and the bottom end of the first spring 16 is located in the mounting hole and the top end is located in the mounting groove. Four first springs 16 are provided, and four mounting holes are provided at predetermined intervals on the top of the limiting block 11, thereby enabling the first springs 16 to stably provide an upward force to the second pressure block 14, preventing misalignment between the first and second impact blocks and the threaded section 104 of the spindle 1.

[0041] Specifically, a third magnetic element 13 is provided on the side of the impact member 12, a second connecting cylinder 10 is sleeved on the outside of the first connecting cylinder 7, and a fourth magnetic element 9 is provided between the first connecting cylinder 7 and the second connecting cylinder 10. The top of the second connecting cylinder 10 is attached to the rotating bearing 5 located at the bottom. Through the cooperation of the third magnetic element 13 and the fourth magnetic element 9, the first impact block and the second impact block move upward, thereby driving the third magnetic element 13 to move upward. Under the action of magnetic force, the fourth magnetic element 9 moves upward rapidly. At this time, the fourth magnetic element 9 strikes the rotating bearing 5, completing the impact operation. Moreover, this magnetic connection method is more convenient and faster to install and disassemble than the traditional mechanical connection method, which can greatly improve the assembly and maintenance efficiency of the device. At the same time, the selection of the third magnetic element 13 and the fourth magnetic element 9 can be flexibly adjusted according to the magnetic field requirements of the actual working environment to meet the needs of different downhole operations.

[0042] Specifically, a reinforcing ring is formed at the bottom of the inner side wall of the second connecting cylinder 10. The reinforcing ring creates a cavity between the first connecting cylinder 7 and the second connecting cylinder 10, which facilitates the installation of the fourth magnetic component 9.

[0043] Specifically, the bottom of the rotor housing 4 is tapered inward to form a sleeve section, the first connecting cylinder 7 is sleeved on the sleeve section, and the rotating bearing 5 is disposed outside the first connecting cylinder 7 and abuts against the position of the corresponding sleeve section of the rotor housing 4, so as to prevent the first connecting cylinder 7 from moving relative to the rotor housing 4 when subjected to vibration, thereby improving the connection stability between the first connecting cylinder 7 and the rotor housing 4.

[0044] Specifically, the cleaning blade 8 has a spiral-shaped liquid guide strip that extends in a spiral shape along the surface of the cleaning blade 8. During the wellbore cleaning process, when the device rotates, the liquid guide strip can guide the liquid in the well to flow in a spiral direction. This guiding effect can, on the one hand, suspend the rock cuttings on the well wall with the fluid movement, allowing the rock cuttings to move together with the fluid and improving the rock cuttings cleaning effect; on the other hand, the flowing liquid can form a certain circulation in the wellbore, allowing the cleaned rock cuttings to be discharged from the wellbore in a timely manner with the liquid, preventing impurities from being deposited again on the inner wall of the wellbore, further improving the efficiency and quality of wellbore cleaning.

[0045] In one specific implementation, the wellbore cleaning and vibration device is placed in the wellbore by connecting an external device to the rotor housing 4. Cleaning fluid is then injected into the wellbore, entering the rotor housing 4. The fluid inside the well flows through the guide vanes to drive the rotor 3 to rotate, thereby causing the stator 2 and the spindle 1 to rotate. When the spindle 1 rotates, it causes the first and second impact blocks to move downwards, disengaging them from the vibration block 701. This causes the second pressure block 14 to compress the first spring 16. After the first and second impact blocks move downwards, the second spring... The spring is reset so that the first impact block and the second impact block pop out in a direction away from the spindle 1. Then the first spring 16 is reset so as to push the first impact block and the second impact block upward, so that the first impact block and the second impact block hit the shock block 701 and move between the shock blocks 701. At this time, the first impact block and the second impact block are acted on by the first impact surface 1201 and the second impact surface and compress the second spring, so that the second impact block and the first impact block fit together and connect, so that the first impact block and the second impact block can be located between the shock blocks 701 again and screwed onto the spindle 1 again. When the spindle 1 rotates, the magnetic force of the first magnetic component 6 and the second magnetic component drives the cleaning blade 8 to rotate to clean the inner wall of the wellbore. The function of the third magnetic component 13 and the fourth magnetic component 9 is to prevent relative displacement between the impact component 12 and the first connecting cylinder 7 during vibration, ensuring the reliability of the entire vibration assembly. At the same time, the first impact block and the second impact block move upward and the third magnetic component 13 moves upward. Under the action of magnetic force, the fourth magnetic component 9 moves upward rapidly. At this time, the fourth magnetic component 9 strikes the rotating bearing 5 to complete the vibration operation.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
