Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection technology, specifically, it relates to an acoustic detection device suitable for high-pressure pipeline fluids. Background Technology

[0002] In the fields of oil and gas field development, natural gas hydrate development, and oil and gas storage and transportation, high-pressure pipelines are the core infrastructure for transporting fluid media. Especially in offshore oil and gas fields, high-pressure pipelines are exposed to high pressure, high humidity, and complex media environments for extended periods, making them highly susceptible to two key problems: First, under temperature fluctuations and high pressure, the fluid media (such as oil, gas, water, and natural gas) inside the pipeline are prone to forming solid hydrates. These hydrates adhere to the inner wall of the pipeline and gradually deposit, potentially leading to a reduction in the pipeline's cross-sectional area or even complete blockage. Second, solid sand particles from the marine environment can easily enter the pipeline with the fluid, forming solid deposits together with hydrates or other impurities, further exacerbating the risk of pipeline blockage. In severe cases, this can interrupt the storage and transportation process, causing economic losses or even safety hazards. To avoid pipeline blockage and ensure storage and transportation safety, the industry needs to accurately detect the fluid distribution, hydrate formation and deposition locations, and solid deposition thickness within high-pressure pipelines in order to take preventative measures in advance. However, current practical operations for such detection lack efficient detection methods specifically adapted to high-pressure pipelines. Therefore, we propose an acoustic detection device suitable for high-pressure pipeline fluids. Utility Model Content

[0003] This invention provides an acoustic detection device suitable for high-pressure pipeline fluids to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An acoustic detection device for high-pressure pipeline fluids includes a pressure block 1, a pressure block 2, an acoustic probe 1, an acoustic probe 2, and a clamping assembly. The pressure block 1 and pressure block 2 are fitted against the outer wall of the high-pressure pipeline. The acoustic probe 1 is embedded within the pressure block 1, and the acoustic probe 2 is embedded within the pressure block 2, with the acoustic probe 1 and acoustic probe 2 arranged coaxially along the radial direction of the high-pressure pipeline. The clamping assembly tightly fixes the pressure block 1 and pressure block 2 to the outer wall of the high-pressure pipeline, thus securing the pressure block 1 and pressure block 2. The acoustic probe 1 and acoustic probe 2 respectively abut against the outer wall of the high-pressure pipeline. The acoustic probe 1 is a sound wave emitting source, and the acoustic probe 2 is a sound wave receiving source.

[0005] Furthermore, the clamping assembly includes two clamping screws. The upper and lower ends of the first clamping block are respectively provided with threaded holes, and the upper and lower ends of the second clamping block are respectively provided with screw holes. The clamping screws pass through the screw holes and are threadedly connected to the threaded holes to fix the first clamping block and the second clamping block.

[0006] Furthermore, the first and second pressure blocks have the same structure, each having two concentric stepped holes. The first acoustic probe is embedded in the stepped hole of the first pressure block, and the second acoustic probe is embedded in the stepped hole of the second pressure block.

[0007] Furthermore, the acoustic probe one and acoustic probe two have the same structure. Both include a probe body and a stepped protrusion on the side of the probe body facing away from the high-pressure pipeline. The shape of the stepped protrusion matches the shape of the inner wall of the stepped hole of the pressure block one and pressure block two. The stepped protrusion is embedded in the stepped hole.

[0008] Furthermore, the probe body has an arc-shaped groove on the side facing the high-pressure pipeline, and the radius of the arc-shaped groove is equal to the radius of the outer wall of the high-pressure pipeline.

[0009] Furthermore, both the first and second pressure blocks have two symmetrical elongated slots for avoiding the outer wall of the high-pressure pipeline and a central circular hole. The inner arc of the central circular hole is adapted to the outer arc of the high-pressure pipeline.

[0010] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, are as follows: During detection, this invention utilizes the differences in sound wave propagation speed and attenuation patterns across different media to identify substances within high-pressure pipelines. Simultaneously, sound wave probe one and sound wave probe two are coaxially arranged radially along the high-pressure pipeline, minimizing the distance between sound wave transmission and reception, reducing sound wave propagation loss to the greatest extent possible, and ensuring the stability and authenticity of the received data. This provides a reliable signal foundation for subsequent analysis. Furthermore, this invention is installed flush against the outer wall of the high-pressure pipeline, eliminating the need for drilling or disassembly, thus completely preserving the original structural integrity of the pipeline and avoiding pipeline strength degradation and leakage risks caused by detection operations. It is particularly suitable for high-pressure, high-risk oil and gas fields and natural gas hydrate storage and transportation scenarios. Attached Figure Description

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] This utility model discloses an acoustic wave detection device suitable for high-pressure pipeline fluids, such as... Figure 1-3 As shown, the system includes a pressure block 1, a pressure block 2, an acoustic probe 3, an acoustic probe 4, and a clamping assembly. Pressure blocks 1 and 2 are attached to the outer wall of the high-pressure pipeline 5. Acoustic probe 3 is embedded in pressure block 1, and acoustic probe 4 is embedded in pressure block 2. Acoustic probe 3 and acoustic probe 4 are coaxially arranged along the diameter of the high-pressure pipeline 5. The clamping assembly tightly fixes pressure blocks 1 and 2 to the outer wall of the high-pressure pipeline 5, thus fixing pressure blocks 1 and 2. At this time, acoustic probe 3 and acoustic probe 4 are respectively in contact with the outer wall of the high-pressure pipeline 5. Acoustic probe 3 is a sound wave emitting source, and acoustic probe 4 is a sound wave receiving source. The working principle and advantages of this utility model are as follows: First, the acoustic probe 3 is embedded in the pressure block 1, and the acoustic probe 4 is embedded in the pressure block 2. The pressure blocks 1 and 2 are respectively attached to the outer wall of the high-pressure pipe 5, and the position is adjusted so that the acoustic probe 3 and the acoustic probe 4 are coaxially aligned along the radial direction of the high-pressure pipe 5. The pressure blocks 1 and 2 are tightly fixed to the outer wall of the high-pressure pipe 5 by the clamping assembly, ensuring that the acoustic probe 3 and the acoustic probe 4 are in close contact with the outer wall of the high-pressure pipe 5. After the device is started, the acoustic probe 3 generates an acoustic signal as an acoustic wave emission source. The acoustic wave is transmitted into the interior of the high-pressure pipe 5 through the outer wall of the pipe. After being acted upon by fluid or sediment, the acoustic probe 4 receives the reflected or transmitted signal. Based on the differences in the conduction speed and law of acoustic waves under different media conditions, the device can... This invention utilizes the characteristics of sound waves to distinguish different substances, as well as the distribution and thickness of sediments. During detection, it leverages the differences in sound wave propagation speed and attenuation patterns in different media to identify substances within the high-pressure pipeline 5. Simultaneously, sound wave probe 3 and sound wave probe 4 are coaxially arranged radially along the high-pressure pipeline 5, minimizing the distance between sound wave transmission and reception, reducing sound wave propagation loss to the greatest extent, ensuring the stability and authenticity of the received data, and providing a reliable signal foundation for subsequent analysis. This invention is installed by fitting it to the outer wall of the high-pressure pipeline 5, eliminating the need for drilling or disassembly, completely preserving the original structural integrity of the high-pressure pipeline 5, and avoiding the risk of pipeline strength degradation and leakage caused by detection operations. It is particularly suitable for high-pressure, high-risk oil and gas fields and natural gas hydrate storage and transportation scenarios.

[0016] In a preferred embodiment of this utility model, the clamping assembly includes two clamping screws 6. Threaded holes 8 are respectively opened at the upper and lower ends of the first clamping block 1, and screw holes 7 are respectively opened at the upper and lower ends of the second clamping block 2. The clamping screws 6 pass through the screw holes 7 and are threadedly connected to the threaded holes 8, thereby fixing the first clamping block 1 and the second clamping block 2. This embodiment uses a simple clamping screw 6 connection method, which can be operated without special tools to complete the installation and disassembly. By adjusting the tightening degree of the clamping screws 6, the clamping force can be flexibly controlled, ensuring that the first acoustic probe 3 and the second acoustic probe 4 are tightly against the high-pressure pipeline 5, while avoiding damage to the high-pressure pipeline 5 due to excessive clamping force.

[0017] In a preferred embodiment of this utility model, pressure block 1 and pressure block 2 have the same structure, both having two concentric stepped holes 10. Acoustic probe 3 is embedded in the stepped hole 10 of pressure block 1, and acoustic probe 4 is embedded in the stepped hole 10 of pressure block 2. Acoustic probe 3 and acoustic probe 4 have the same structure, both including a probe body 9 and a stepped protrusion 11 on the side of the probe body 9 facing away from the high-pressure pipe 5. The shape of the stepped protrusion 11 matches the shape of the inner wall of the stepped hole 10 of pressure block 1 and pressure block 2. The stepped protrusion 11 is embedded in the stepped hole 10. In this embodiment, after the stepped protrusion 11 is embedded in the stepped hole 10, the outer wall of the stepped protrusion 11 fits against the inner wall of the stepped hole 10, which can limit the radial displacement of the probe body 9 and prevent vibration from causing the probe body 9 to sway left and right. The end face of the stepped protrusion 11 fits against the shoulder of the stepped hole 10, which can limit the axial displacement of the probe body 9 and prevent the probe body 9 from being over-embedded or loosened and dislodged.

[0018] Specifically, the probe body 9 has an arc-shaped groove on the side facing the high-pressure pipe 5. The radius of the arc-shaped groove is equal to the radius of the outer wall of the high-pressure pipe 5. This allows for a seamless and complete fit between the probe body 9 and the outer wall of the high-pressure pipe 5, completely eliminating the air gap between them. Air causes significant reflection and attenuation of sound waves. The seamless fit allows sound waves to be efficiently transmitted directly between the probe body 9 and the wall of the high-pressure pipe 5, making the amplitude and frequency of the received signal clearer and facilitating the differentiation of different media.

[0019] In a preferred embodiment of this utility model, both pressure block 1 and pressure block 2 have two symmetrical elongated slots 12 and a central circular hole 13. The elongated slots 12 are used to avoid the connectors on the outer wall of the high-pressure pipeline 5. The inner arc of the central circular hole 13 is adapted to the outer arc of the high-pressure pipeline 5. The elongated slots 12 can directly avoid the connectors on the outer wall of the high-pressure pipeline 5, which protects the sealing and structural integrity of the high-pressure pipeline 5 and avoids installation conflicts. Especially for visible pipelines, if the connectors on the visible pipeline are disassembled and then reinstalled, the seal of the visible pipeline will be damaged, resulting in poor sealing. This embodiment does not require disassembling the connectors on the high-pressure pipeline 5. The inner wall of the central circular hole 13 is adapted to the outer arc of the high-pressure pipeline 5, which can increase the contact area between pressure block 1, pressure block 2 and the outer wall of the high-pressure pipeline 5, disperse the clamping force of the clamping assembly, and avoid the sliding or displacement of pressure block 1 and pressure block 2 due to the small local contact area.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
