Description

Technical Field

[0001] This utility model relates to the field of oil pipe impact unblocking technology, specifically to an impact unblocking device for oil pipes used in oil extraction. Background Technology

[0002] In oil extraction, the tubing serves as the sole conduit for transporting underground oil and gas resources to the surface, and its unobstructed flow directly impacts well productivity and extraction efficiency. However, over time, the inner wall of the tubing is highly susceptible to wax deposition, scaling, and the formation of asphalt and gum deposits due to variations in bottom-hole temperature and pressure, as well as the complexity of crude oil composition. These deposits gradually reduce the effective flow area of ​​the tubing, and in severe cases, can completely block it, leading to a sharp decline in well production. Therefore, when well production drops below the economically viable production threshold due to blockage, effective unblocking measures must be implemented to restore the tubing's normal flow capacity. This is a crucial technical step in maintaining stable and increased oilfield production.

[0003] Currently, traditional oil pipe unblocking technologies are mainly divided into two categories: chemical unblocking and mechanical unblocking. Chemical unblocking involves injecting specific chemical agents (such as wax removers and scale removers) into the oil pipe to dissolve the blockage. However, this method is costly, and the chemical agents may pollute the environment and corrode the oil pipe itself. Mechanical unblocking uses tools such as wax scrapers and drill bits to scrape or mill the inner wall of the oil pipe, physically removing the blockage. However, mechanical unblocking is a contact operation, and the intense friction between the tool and the pipe wall can easily damage the inner wall of the oil pipe, causing scratches, thinning, or even rupture, posing a significant safety hazard to subsequent production. Furthermore, both methods usually require interrupting production and using specialized equipment, making the process complex and inefficient.

[0004] CN223482602U discloses an impact-based unblocking method for oil extraction tubing, comprising a tubing body with an impact-resistant layer on its inner side and an unblocking frame on its outer side. The unblocking frame has two valves at both ends, with an impact channel between them. An ultrasonic cleaner is located at the top of the impact channel. When unblocking is needed, one end of the tubing is sealed by closing one of the valves, and then the ultrasonic cleaner is activated to generate high-frequency resonance. The ultrasonic waves are transmitted to the inner wall of the tubing through the impact channel, utilizing the cavitation effect and vibration of the ultrasound to impact and unblock the clogged oil. This solution employs non-contact ultrasonic technology, effectively avoiding physical damage to the tubing wall caused by traditional mechanical unblocking methods, achieving a certain degree of efficient and non-destructive unblocking.

[0005] However, this existing technology still has significant limitations in practical applications. Because its unblocking frame is fixedly installed on a specific section of the pipe, and the impact channel has a limited length, the ultrasonic cleaner can only unblock sections near that fixed location. When the blockage point in the oil pipe is located in a section outside the unblocking frame's installation position, the device cannot function, resulting in a limited unblocking range and difficulty in meeting the comprehensive unblocking needs of long-distance oil pipes. To achieve full-coverage unblocking along the entire oil pipe, multiple unblocking frames would need to be installed at intervals along the pipeline, which would undoubtedly significantly increase equipment costs and the complexity of installation and maintenance. Utility Model Content

[0006] The purpose of this invention is to provide an impact unblocking device for oil pipelines in oil extraction, which solves the problem that the existing technology can only perform impact unblocking at fixed positions on the oil pipeline, the unblocking range is limited, and it cannot cover the entire oil pipeline, resulting in the need to install multiple unblocking frames for long-distance oil pipelines, which increases equipment costs and maintenance difficulty.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] An impact unblocking device for oil extraction pipelines includes:

[0009] A base, wherein a channel is provided on the base;

[0010] A blockage-removing chamber is located in the middle of the base; the blockage-removing chamber is connected to the channel respectively;

[0012] A vibration unblocking assembly is disposed inside the unblocking chamber and is in contact with the outer wall of the oil pipe passing through the unblocking chamber;

[0013] The vibration unblocking component is used to apply high-frequency vibration to the oil pipe during the process of the oil pipe being transported through the unblocking chamber, so that the blockage on the inner wall of the oil pipe is dislodged under the action of vibration.

[0014] A further technical solution is that the vibration unblocking assembly further includes a vibration ring, a contact ring, and multiple ultrasonic vibrating elements; the multiple ultrasonic vibrating elements are arranged in a circular array around the axis and fixed to the inner side of the vibration ring; the inner side of the contact ring is used to contact the outer periphery of the oil pipe.

[0015] A further technical solution is that the channel includes an inclined guide channel and a horizontally arranged delivery channel; the oil pipe delivery assembly is located within the guide channel; and the unblocking chamber is located in the middle of the delivery channel.

[0016] The oil pipe delivery assembly is used to obliquely deliver the oil pipe through the guide channel into a horizontally arranged delivery channel.

[0017] A further technical solution is that the opposite sidewalls of the guide channel are provided with guide grooves; the oil pipe conveying assembly includes a driving component and a plurality of conveying rollers arranged in the guide grooves along the conveying direction; the driving component is used to drive the conveying rollers to rotate, so as to drive the oil pipe to pass through the unblocking chamber at a uniform speed.

[0018] A further technical solution is that the base is provided with a guide assembly located on the transition section between the guide channel and the conveying channel; the guide assembly includes a guide half-tube; the guide half-tube is covered above the conveying channel.

[0019] A further technical solution is that the guide assembly also includes a frame, a telescopic component, and a downward pressure arc plate; the frame is fixed to the base and located above the guide half-tube; the telescopic component is fixed to the frame and has a telescopic end that can move vertically; the telescopic end slides through and extends into the guide half-tube and is fixed to the downward pressure arc plate.

[0020] A further technical solution is that the guide assembly also includes a top plate, an elastic element, and multiple guide rollers; the multiple guide rollers are arranged along the conveying direction on the bottom side of the top plate; the bottom side of the top plate is fixed to the lower pressure arc plate by the elastic element.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This application achieves full-length unblocking of the entire oil pipe by using a coordinated operation of the tubing delivery assembly and the vibration unblocking assembly. This completely solves the technical shortcomings of existing unblocking devices, which can only be fixed at a certain location on the oil pipe, limiting the unblocking range to the vicinity of the installation point. As the oil pipe passes through the unblocking chamber at a constant speed, the vibration unblocking assembly continuously operates, freeing the unblocking range from the fixed installation point. This eliminates the need for multiple unblocking frames installed at intervals on the oil pipe, significantly reducing equipment costs and on-site installation complexity. Furthermore, the vibration unblocking method uses a non-contact or flexible contact approach, which, compared to traditional mechanical scraping methods, does not cause physical damage to the inner wall of the oil pipe, ensuring the structural integrity and service life of the oil pipe.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example:

[0034] like Figures 1-7 As shown, this utility model provides an impact unblocking device for oil pipes in oil extraction, including a base 1, an unblocking chamber 11, an oil pipe conveying assembly 2, and a vibration unblocking assembly 3; a channel is provided on the top side of the base 1; the unblocking chamber 11 is located in the middle of the base 1; the unblocking chamber 11 is connected to the channel; the oil pipe conveying assembly 2 is located on the base 1; the oil pipe conveying assembly 2 is used to send the blocked oil pipe into and out of the channel; the vibration unblocking assembly 3 is located inside the unblocking chamber 11 and is in contact with the outer wall of the oil pipe passing through the unblocking chamber 11; the vibration unblocking assembly 3 is used to apply high-frequency vibration to the oil pipe during the process of the oil pipe being conveyed through the unblocking chamber 11, so that the blockage on the inner wall of the oil pipe is dislodged under the action of vibration.

[0035] The principles and beneficial effects of the above technical solution:

[0036] When an oil pipe becomes blocked during oil extraction and requires unblocking, the blocked pipe is first removed from the well and then placed at the inlet of the base 1 of this device. The pipe is driven forward at a constant speed along the channel by the pipe delivery assembly 2. When the pipe enters the unblocking chamber 11, the vibration unblocking assembly 3 contacts the outer wall of the pipe and initiates high-frequency vibration. As the pipe continues to move through the unblocking chamber 11, the high-frequency vibration is transmitted through the pipe wall to the inner wall, causing fatigue cracks in the wax, scale, asphalt, and other blockages adhering to the inner wall under the continuous alternating vibration force, leading to their gradual detachment. The delivery assembly then sends the treated pipe out of the channel outlet, completing the unblocking operation for the entire pipe.

[0037] This solution achieves full-length unblocking of the entire oil pipe by coordinating the oil pipe delivery assembly 2 and the vibration unblocking assembly 3. This completely overcomes the technical limitations of existing unblocking devices, which can only be fixed at a specific location on the oil pipe, restricting the unblocking range to the vicinity of the installation point. As the oil pipe passes through the unblocking chamber 11 at a constant speed, the vibration unblocking assembly 3 continuously operates, freeing the unblocking range from the fixed installation point. This eliminates the need for multiple unblocking frames installed at intervals on the oil pipe, significantly reducing equipment costs and on-site installation complexity. Furthermore, the vibration unblocking method employs non-contact or flexible contact, avoiding physical damage to the inner wall of the oil pipe compared to traditional mechanical scraping methods, thus ensuring the structural integrity and service life of the oil pipe.

[0038] In this embodiment, the vibration unblocking component 3 also includes a vibration ring 31, a contact ring 32, and multiple ultrasonic vibrators; the multiple ultrasonic vibrators are arranged in a circular array around the axis and fixed to the inner side of the vibration ring 31; the inner side of the contact ring 32 is used to contact the outer periphery of the oil pipe.

[0039] Specifically, one end of the vibration ring 31 is detachably connected to a shielding ring 33 by bolts; a receiving groove 331 is opened on one side of the shielding ring 33; the vibration ring 31 is bolted to the inner wall of the unblocking chamber 11 by two linkage blocks 34 on the outer periphery; one end of the vibration groove 37 extends to the end of the vibration ring 31.

[0040] Specifically, the ultrasonic vibrating component includes a generator (not shown in the figure), a transducer 35, a power supply (not shown in the figure), and a switch 36; the inner wall of the vibration ring 31 has multiple vibration grooves 37 arranged in a circular array around the axis; the transducer 35 is horizontally engaged in the vibration groove 37; the transducer 35 and the power supply are installed in the receiving groove 331; the switch 36 is installed on the base 1; the contact ring 32 is coaxially fixed to the inner side of the vibration ring 31 and contacts the transducer 35.

[0041] The principles and beneficial effects of the above technical solution:

[0042] When the oil pipe enters the unblocking chamber 11 and passes through the vibrating ring 31, the inner side of the contact ring 32 is in close contact with the outer wall of the oil pipe. After the ultrasonic vibrator is activated, the power is turned on by the switch 36, and the generator produces a high-frequency electrical signal. The transducer 35 converts the high-frequency electrical signal into high-frequency mechanical vibration, and the vibration energy is directly transmitted to the outer wall of the oil pipe through the contact ring 32. This control principle is a conventional existing technology in the field of ultrasonic cleaning technology, so its specific circuit connection and working frequency adjustment method will not be described in detail here. Since multiple ultrasonic vibrators are arranged in a circular array, the vibration energy is evenly distributed along the circumference of the oil pipe, so that the pipe wall is subjected to a balanced vibration force in all directions. The shielding ring 33 and the receiving groove 331 are used to protect the transducer 35 and the power supply, preventing debris generated during the vibration process from entering and damaging the precision components. The linkage block 34 fixes the vibrating ring 31 to the inner wall of the unblocking chamber 11 to ensure the stability of the overall structure during the vibration process.

[0043] This design, through the combined design of a vibration ring 31, a contact ring 32, and multiple ultrasonic vibrating components, achieves uniform distribution and efficient transmission of vibration energy along the circumference of the tubing, solving the problem of uneven unblocking that may be caused by vibration in one direction. The circular array arrangement ensures balanced force at all points on the outer wall of the tubing, allowing the blockage on the inner wall to be impacted by vibration from all directions, improving the efficiency and thoroughness of unblocking. The tight fit between the contact ring 32 and the outer wall of the tubing ensures effective transmission of vibration energy and reduces energy loss. The detachable connection structure between the vibration ring 31 and the unblocking chamber 11 facilitates the inspection and maintenance of the device, while the design of the shielding ring 33 and the receiving groove 331 enhances the durability and reliability of the equipment under harsh operating conditions.

[0044] In this embodiment, the channel includes an inclined guide channel 12 and a horizontally arranged conveying channel 13; the oil pipe conveying assembly 2 is disposed in the guide channel 12; the unblocking chamber 11 is disposed in the middle of the conveying channel 13; the oil pipe conveying assembly 2 is used to convey the oil pipe at an incline through the guide channel 12 into the horizontally arranged conveying channel 13.

[0045] The principles and beneficial effects of the above technical solution:

[0046] The channel is divided into an inclined guide section and a horizontal conveying section. The oil pipe first enters the inclined guide channel 12 and moves upward or downward along the inclined direction under the drive of the conveying component, then transitions to the horizontal conveying channel 13. The unblocking chamber 11 is located in the middle of the horizontal conveying channel 13. When the oil pipe enters the horizontal section from the inclined section, it passes through the unblocking chamber 11 in a stable horizontal posture, ensuring stable and reliable contact between the vibration unblocking component 3 and the outer wall of the oil pipe. The design of the inclined guide channel 12 facilitates the easy entry of the oil pipe into the device from its ground storage location, while utilizing gravity to assist the movement of the oil pipe, reducing conveying energy consumption.

[0047] This solution, through the combined design of the inclined guide channel 12 and the horizontal conveying channel 13, solves the problem of difficulty in aligning the inlet end and the tendency to jam when long oil pipes are directly fed into the device in the horizontal direction. The inclined guide channel 12 provides more relaxed inlet conditions; the operator only needs to place the end of the oil pipe into the guide groove 4, and the conveying component will automatically introduce the oil pipe into the device. The horizontal conveying channel 13 ensures the stability of the oil pipe when passing through the unblocking chamber 11, avoiding uneven contact due to vibration caused by the inclination of the oil pipe. This channel layout makes the device more versatile, capable of handling oil pipes of different lengths and diameters, while improving the automation level and ease of operation.

[0048] In this embodiment, the opposite sidewall of the guide channel 12 is provided with a guide groove 4; the oil pipe conveying assembly 2 includes a driving member and a plurality of conveying rollers 21 arranged in the guide groove 4 along the conveying direction; the driving member is used to drive the conveying rollers 21 to rotate so as to drive the oil pipe to pass through the unblocking chamber 11 at a uniform speed;

[0049] Specifically, the two ends of the conveying roller are rotatably mounted on the opposite sidewalls of the guide groove 4 via a rotating shaft; the rotating shaft at the top of the conveying roller rotates through and extends out of the base 1; the driving component includes a drive motor 22, a drive gear 23, and an annular rack (not shown in the figure); the drive gear 23 is coaxially fixed to the power end of the drive motor 22 and the rotating shaft, and is linked by the annular rack; the drive motor 22 is a servo motor; a shield 24 is detachably connected to the base 1 by bolts; the shield 24 is used to shield the driving component and the rotating shaft.

[0050] The principles and beneficial effects of the above technical solution:

[0051] The conveying rollers 21 are arranged along the guide groove 4, with both ends of their rotating shafts mounted on the side walls of the guide groove 4. The top rotating shaft extends out of the base 1 and connects to the drive gear 23. After the drive motor 22 starts, it transmits power to each conveying roller 21 through the linkage mechanism of the drive gear 23 and the ring rack, causing all rollers to rotate synchronously. The oil pipe is placed in the guide groove 4, in contact with the conveying rollers 21, and moves forward at a constant speed along the guide channel 12 under the drive of the roller friction. The use of a servo motor can precisely control the conveying speed and adjust the time it takes for the oil pipe to pass through the unblocking chamber 11. The shield 24 protects the drive components and rotating shafts, preventing foreign objects from entering and affecting the transmission.

[0052] This solution uses the synchronous rotation of multiple conveying rollers 21 to drive the oil pipe at a uniform speed, solving the problem of insufficient or excessive vibration time caused by unstable speed during the unblocking process. Multiple rollers are arranged along the conveying direction, providing multi-point support for the long oil pipe and preventing bending deformation due to its own weight during movement. This ensures the oil pipe remains centered in the channel and maintains good contact with the vibration unblocking component 3. A servo motor precisely controls the conveying speed, allowing operators to adjust the unblocking time according to the degree of blockage, improving the controllability of the unblocking effect. The linkage design of the ring rack ensures consistent rotation speed of all rollers, preventing twisting or deviation of the oil pipe during conveying. The shield 24 enhances the safety and service life of the transmission system.

[0053] In this embodiment, a guide component 5 is provided on the base 1 on the transition section between the guide channel 12 and the conveying channel 13; the guide component 5 includes a guide half tube 51; the guide half tube 51 covers the conveying channel 13.

[0054] The principles and beneficial effects of the above technical solution:

[0055] A guide half-pipe 51 is installed at the transition position between the guide channel 12 and the delivery channel 13. This half-pipe covers the delivery channel 13, forming a guiding and limiting structure for the oil pipe. When the oil pipe enters the horizontal delivery channel 13 from the inclined guide channel 12, the guide half-pipe 51 guides the end of the oil pipe smoothly into the delivery channel 13, preventing the oil pipe from deviating due to gravity or inertia in the transition section, and ensuring that the oil pipe accurately enters the unblocking chamber 11.

[0056] This solution, through the installation of the guide half-pipe 51, solves the problems of deviation from the track, jamming, or collision with the sidewall of the channel that easily occur when the oil pipe transitions from the inclined section to the horizontal section. The guide half-pipe 51 forms a closed or semi-closed guide space above the transition section, forcibly constraining the travel path of the oil pipe and ensuring that the oil pipe smoothly and accurately enters the delivery channel 13 and the unblocking chamber 11.

[0057] In this embodiment, the guide assembly 5 also includes a frame 52, a telescopic member 53, and a downward pressing arc plate 54; the frame 52 is fixed on the base 1 and located above the guide half tube 51; the telescopic member 53 is fixed on the frame 52 and has a telescopic end that can move vertically; the telescopic end slides through and extends into the guide half tube 51 and is fixed to the downward pressing arc plate 54; the telescopic member 53 is an electric cylinder.

[0058] The principles and beneficial effects of the above technical solution:

[0059] The frame 52 provides stable support for the telescopic component 53. The telescopic end of the telescopic component 53 (electric cylinder) extends downward into the guide half-tube 51 and is fixedly connected to the downward pressure arc plate 54. When the oil pipe enters the area of ​​the guide half-tube 51, the telescopic component 53 is extended, causing the downward pressure arc plate 54 to move downward and press against the upper outer wall of the oil pipe. The arc surface design of the downward pressure arc plate 54 fits against the outer wall of the oil pipe, applying appropriate downward pressure to the oil pipe to ensure that the oil pipe always maintains close contact with the conveying roller 21 during the conveying process, preventing the oil pipe from jumping or deviating.

[0060] This solution utilizes the active clamping function of the downward-pressing arc plate 54 to solve the problems of bouncing and misalignment that may occur in the oil pipe during high-speed transport or vibration, ensuring that the oil pipe maintains stable contact with the conveying roller 21 and the vibration unblocking component 3 at all times. The extension and retraction control of the electric cylinder can adjust the downward pressure to accommodate oil pipes of different diameters and weights, improving the versatility of the device. It enhances the stability of the conveying system, providing reliable contact conditions for subsequent vibration unblocking and preventing a decrease in vibration energy transfer efficiency due to poor contact.

[0061] In this embodiment, the guide assembly 5 further includes a top plate 55, an elastic element 56, and a plurality of guide rollers 57; the plurality of guide rollers 57 are arranged along the conveying direction on the bottom side of the top plate 55; the bottom side of the top plate 55 is fixed to the lower pressure arc plate 54 by the elastic element 56; specifically, the elastic element 56 is a spring.

[0062] The principles and beneficial effects of the above technical solution:

[0063] Below the pressing arc plate 54, a top plate 55 is connected via an elastic element 56 (spring). Multiple guide rollers 57, arranged along the conveying direction, are mounted on the bottom side of the top plate 55. When the pressing arc plate 54 presses against the oil pipe, the elastic element 56 causes the top plate 55 and the guide rollers 57 to contact the oil pipe surface elastically. The guide rollers 57 can rotate freely during oil pipe conveying, converting sliding friction into rolling friction and reducing wear on the oil pipe surface. The buffering effect of the elastic element 56 absorbs unevenness or minor vibrations on the oil pipe surface, ensuring the rollers remain in contact with the oil pipe.

[0064] This solution, through the combined design of guide rollers 57 and elastic elements 56, solves the problem of potential scratches or wear on the tubing surface caused by rigid clamping. The rolling contact method of the guide rollers 57 significantly reduces frictional resistance, protecting the outer wall of the tubing and reducing energy consumption of the delivery system. The buffering effect of the elastic elements 56 can adapt to minor unevenness on the tubing surface, maintaining constant contact pressure and ensuring the stability of the tubing during vibration-based unblocking. Multiple rollers arranged along the delivery direction form continuous support, further enhancing the smoothness of the tubing during travel and creating favorable conditions for efficient unblocking.

[0065] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
