Description

Technical Field

[0001] The invention belongs to the technical field of pipeline anti-blocking and anti-silting, and specifically relates to a non-invasive oil and gas pressure pipeline anti-blocking and anti-silting device and method. Background Art

[0002] In the process of oil and gas exploration and production, pressure pipelines are key facilities for transporting various types of liquid-solid or gas-liquid-solid mixed fluids, and their operating status is directly related to production efficiency and safety. However, due to the complex layout of the pipeline, there are a large number of bends and diameter changes, which often become hotspots for solid phase materials in the fluid to deposit, stick and cause blockage. Once the pipeline is blocked, it will not only affect the normal flow of the fluid, but may also cause pressure build-up, damage equipment, and even cause serious production safety accidents, resulting in casualties, economic losses and environmental pollution.

[0003] To solve the blockage problem of oil and gas pressure pipelines, existing technologies mainly rely on invasive equipment for cleaning, such as flushing, scraping, etc. However, these methods have many disadvantages:

[0004] Damage to pipeline integrity: When invasive equipment operates inside the pipeline, it needs to be connected to external systems such as flushing fluid sources, power sources, etc. These connection points may become potential sources of leakage, destroying the sealing and integrity of the pressure pipeline and increasing the risk of fluid leakage.

[0005] Increase fluid flow resistance: Invasive equipment with complex structures occupies a certain space in the pipeline, which will change the flow trajectory of the fluid, increase flow friction, and affect the normal working efficiency of the pipeline. This effect is more significant in pipelines with high flow rate or high pressure difference.

[0006] Damage to the inner wall of the pipeline: When using physical methods such as scraping to remove blockages, it is easy to cause scratches, wear and other damage to the inner wall of the pipeline. Over a long period of time, these damages will accumulate and intensify, seriously affecting the service life and safety of the pipeline.

[0007] Impact on production efficiency: Invasive cleaning equipment requires downtime for installation, commissioning and operation, which is a cumbersome and time-consuming process that will seriously affect on-site production efficiency. At the same time, frequent downtime for cleaning will also increase production costs and maintenance difficulties.

[0008] Limited cleaning effect: For some stubborn blockages or deposits, invasive cleaning equipment may not be able to completely remove them, resulting in unsatisfactory cleaning effects. In addition, new blockages or deposits may be generated during the cleaning process, forming a vicious cycle.

[0009] In summary, the existing invasive oil and gas pressure pipeline cleaning methods have many drawbacks, which has become a problem that the technicians in this field need to solve urgently. Therefore, it is necessary to propose a non-invasive oil and gas pressure pipeline anti-blocking and anti-silting device and method. Summary of the invention

[0010] In order to solve the above problems, the purpose of the present invention is to provide a non-invasive oil and gas pressure pipeline anti-blocking and anti-silting device and method, which detects and removes pipeline siltation through ultrasonic wave, and removes silt in the pipeline in a non-invasive manner.

[0011] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a non-invasive oil and gas pressure pipeline anti-blocking and anti-silting device, characterized in that it includes a pipeline detection and anti-blocking component, a signal processor, an ultrasonic generator and a human-computer interaction system, the pipeline detection and anti-blocking component includes an ultrasonic detection probe and an ultrasonic transducer, which are used to detect pipeline wall thickness information and remove pipeline siltation by using the ultrasonic field; the signal processor is used to control the ultrasonic detection probe to emit detection waves and analyze the detection results; the ultrasonic generator is used to control the ultrasonic transducer to generate ultrasonic waves; the human-computer interaction system is used to control the working parameters of the signal processor and the ultrasonic generator through the human-computer interaction interface, the pipeline detection and anti-blocking component is connected to the signal processor, the ultrasonic generator and the human-computer interaction system through a signal cable, and the outer wall of the pipeline detection and anti-blocking component is also fixedly connected to a protective shell, which is used to protect the ultrasonic detection probe and the ultrasonic transducer from continuous and stable operation.

[0012] Furthermore, a non-invasive oil and gas pressure pipeline anti-blocking and anti-silting method comprises the following steps: Step 1, initial setting and installation: first, a pipeline detection and anti-blocking component (3) is fixed to a pre-selected siltation-prone area on the outer wall of the oil and gas pressure pipeline, with the sound wave emitting surfaces of the ultrasonic detection probe (1) and the ultrasonic transducer (2) facing the inside of the oil and gas pressure pipeline;

[0013] Step 2: Regular inspection: Start and set the operating parameters of the human-computer interaction system (6) and conduct regular inspections on the pipeline;

[0014] Step 3, ultrasonic desilting: after judging the siltation based on the wall thickness information and confirming that the pipeline is blocked or silted, the ultrasonic transducer (2) emits ultrasonic desilting ultrasound;

[0015] Step 4: Feedback and maintenance: After the desilting operation is completed, re-feedback operation is performed and the user performs daily maintenance.

[0016] Furthermore, in step one, the human-computer interaction system also includes a remote monitoring module for realizing remote communication between the user and the human-computer interaction system through wireless communication.

[0017] Furthermore, in step one, the human-computer interaction system also includes an alarm module for automatically triggering an alarm when the signal processor detects severe blockage or siltation.

[0018] Furthermore, in step 2, regular detection means that the ultrasonic detection probe, under the control of the signal processor, emits detection sound waves at preset intervals to detect blockage and siltation inside the pipeline.

[0019] Furthermore, in step three, siltation judgment refers to the signal processor receiving and analyzing the detection signal returned by the ultrasonic detection probe, comparing the pipeline wall thickness information in the detection signal with the preset pipeline standard wall thickness, and judging whether there is blockage and siltation in the pipeline, and displaying the judgment result through the human-computer interaction system.

[0020] Furthermore, in step three, when the signal processor detects blockage and siltation in the pipeline, the human-computer interaction system alerts the user through the remote monitoring module and the alarm module.

[0021] Furthermore, in step three, when the signal processor detects blockage and siltation in the pipeline, the human-computer interaction system sends instructions to the ultrasonic generator to control the ultrasonic transducer to emit silt-removing ultrasonic waves, and the frequency, power and duration of the silt-removing ultrasonic waves are adjusted through the human-computer interaction system.

[0022] Furthermore, in step 4, the re-feedback operation means that after the ultrasonic desilting is completed, the pipeline detection and anti-blocking components will detect again to evaluate the desilting effect. If the preset pipeline wall thickness is not reached, the ultrasonic parameters will be adjusted through the human-computer interaction system to repeat the ultrasonic desilting.

[0023] Furthermore, in step four, daily maintenance refers to the user implementing remote monitoring, parameter adjustment and alarm information processing through the remote monitoring module.

[0024] The following principles and beneficial effects are achieved by adopting the above scheme:

[0025] 1. The present invention uses an ultrasonic detection probe to emit detection sound waves into the interior of the pipeline, and obtains information on the pipeline wall thickness and internal siltation through the reflection and transmission characteristics of the sound waves in the pipeline wall and the internal medium. This technology does not require direct contact with the interior of the pipeline, and realizes non-invasive detection. When siltation is detected inside the pipeline, the ultrasonic transducer, under the control of the ultrasonic generator, emits ultrasonic waves of a specific frequency and power into the interior of the pipeline. When ultrasonic waves propagate in the pipeline, cavitation effects, vibration effects, etc. are generated, causing the silt to be destroyed and gradually removed. Intelligent control of the detection and silt removal process is achieved through the human-computer interaction system. The system can automatically perform detection tasks according to preset parameters, and automatically adjust the parameters of the silt removal ultrasonic wave according to the detection results to achieve the best silt removal effect.

[0026] 2. The present invention utilizes the "cavitation" effect, "chemical" effect, "shear" effect, and "simulation" effect of ultrasound, and uses a strong sound field to process the fluid, so that the physical form and chemical properties of the silt in the fluid undergo a series of changes under the action of the ultrasonic field, so that the silt in the fluid undergo a series of changes, and the silt is dispersed, crushed, loosened, and not easily deposited on the pipe wall to form scale. This method will not damage the pipe wall and will not cause any harm to the pipeline body. Compared with other silt removal methods, it can greatly improve the service life of the pipeline.

[0027] 3. The present invention does not require human intervention, integrates detection and silt removal, and monitors the siltation of the pressure pipeline at any time after setting the pipeline siltation limit. When the limit is reached, silt removal begins immediately to keep the pipeline unobstructed at all times, greatly improving the efficiency of silt removal.

[0028] 4. The ultrasonic detection device of the present invention detects the pipeline condition in real time, and the returned pipeline wall thickness information can be used as an important indicator for the maintenance and scrapping of pressure pipelines, and guide pipeline maintenance work.

[0029] 5. The present invention uses non-invasive equipment to remove silt, does not damage the integrity of the pipeline, and avoids the risk of pressure pipeline leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is further described in detail through specific implementation methods:

[0034] The embodiment is basically as shown in the attached Figure 1 and Figure 2 As shown: A non-invasive oil and gas pressure pipeline anti-blocking and anti-silting device and method, comprising the following steps:

[0035] Step 1, initial setup and installation: First, prepare the pipeline detection and anti-blocking component 3, signal processor 5, ultrasonic generator 4 and human-computer interaction system 6. The pipeline detection and anti-blocking component 3 includes an ultrasonic detection probe 1 and an ultrasonic transducer 2, which are used to detect the pipeline wall thickness information and use the ultrasonic field to remove pipeline siltation. The outer wall of the pipeline detection and anti-blocking component 3 is also fixedly connected to a protective shell 9 to protect the ultrasonic detection probe 1 and the ultrasonic transducer 2 for continuous and stable operation.

[0036] The signal processor 5 is used to control the ultrasonic detection probe 1 to transmit detection waves and analyze detection results.

[0037] The ultrasonic generator 4 is used to control the ultrasonic transducer 2 to generate ultrasonic waves.

[0038] The human-machine interaction system 6 is used to control the working parameters of the signal processor 5 and the ultrasonic generator 4 through the human-machine interaction interface. The human-machine interaction system 6 also includes a remote monitoring module 7, which is used to realize remote communication between the user and the human-machine interaction system 6 through wireless communication. The human-machine interaction system 6 also includes an alarm module 8, which is used to automatically trigger an alarm when the signal processor 5 detects severe blockage or siltation.

[0039] The pipeline detection and anti-blocking component 3 is connected to the signal processor 5, the ultrasonic generator 4 and the human-computer interaction system 6 through a signal cable. The pipeline detection and anti-blocking component 3 is fixed to a pre-selected siltation-prone area on the outer wall of the oil and gas pressure pipeline by welding or clamping. The sound wave emitting surfaces of the ultrasonic detection probe 1 and the ultrasonic transducer 2 face the inside of the pipeline and are close to the outer wall of the oil and gas pressure pipeline.

[0040] Step 2, regular inspection: start and set the operating parameters of the human-machine interaction system 6, and the ultrasonic detection probe 1, under the control of the signal processor 5, emits detection sound waves at preset intervals to detect blockage and siltation inside the pipeline.

[0041] Step 3, ultrasonic desilting: The signal processor 5 receives and analyzes the detection signal returned by the ultrasonic detection probe 1, and compares and determines whether there is blockage and siltation in the pipeline according to the pipeline wall thickness information in the detection signal and the preset pipeline standard wall thickness, and displays the judgment result through the human-computer interaction system 6. When the signal processor 5 detects blockage and siltation in the pipeline, the human-computer interaction system 6 alarms the user through the remote monitoring module 7 and the alarm module 8. After confirming that the pipeline is blocked or silted, the human-computer interaction system 6 sends a command to the ultrasonic generator 4 to control the ultrasonic transducer 2 to emit a desilting ultrasonic wave, and the frequency, power and duration of the desilting ultrasonic wave are adjusted by the human-computer interaction system 6.

[0042] Step 4, feedback and maintenance: After the desilting operation is completed, the pipeline detection and anti-blocking component 3 performs detection again to evaluate the desilting effect. If the preset pipe wall thickness is not reached, the ultrasonic parameters are adjusted through the human-computer interaction system 6 to repeat the ultrasonic desilting. At the same time, the user performs daily maintenance, and remote monitoring, parameter adjustment and alarm information processing are realized through the remote monitoring module 7.

[0043] Specific implementation steps:

[0044] Assume that there is a 5-kilometer-long oil and gas pressure pipeline in an oil and gas field. Because the pipeline contains a certain amount of impurities in the transport medium, it is easy to form siltation in some curved sections and low-velocity areas of the pipeline after long-term operation, affecting the flow capacity and safety of the pipeline. In order to keep the pipeline unobstructed, it is decided to use the above-mentioned non-invasive anti-blocking and anti-silting method for regular maintenance.

[0045] Step 1, initial setup and installation: The user first prepares the pipeline detection and anti-blocking component 3 including the ultrasonic detection probe 1, ultrasonic transducer 2, protective shell 9, signal processor 5, ultrasonic generator 4 and human-computer interaction system 6. In the pre-selected siltation-prone areas of the pipeline, such as curved sections and low flow rate areas, the pipeline detection and anti-blocking component 3 is fixed to the outer wall of the pipeline by welding or clamping. Make sure that the sound wave emitting surface of the ultrasonic detection probe 1 and ultrasonic transducer 2 is close to the outer wall of the pipeline and faces the inside of the pipeline. At the same time, install the protective shell 9 to protect the ultrasonic detection probe 1 and ultrasonic transducer 2.

[0046] The pipeline detection and anti-blocking component 3 is connected to the signal processor 5, the ultrasonic generator 4 and the human-machine interaction system 6 through a signal cable. Through the interface of the human-machine interaction system 6, the operating parameters are set, including the detection interval time, the parameters of ultrasonic desilting such as frequency, power, duration, etc., and the remote monitoring and alarm functions are enabled.

[0047] Step 2: Regular inspection: at a preset interval, such as once a week, the ultrasonic detection probe 1 automatically emits detection sound waves under the control of the signal processor 5 to detect blockage and siltation inside the pipeline. The detection results are displayed in real time on the interface of the human-computer interaction system 6.

[0048] Step 3: Ultrasonic desilting. During a regular inspection, the system detects significant silting in a certain section of the pipeline. After analyzing the detection signal, the signal processor 5 displays the detection result through the human-computer interaction system 6, and triggers the alarm module 8 to send an alarm message to the user. After the user confirms the alarm message, the human-computer interaction system 6 adjusts the parameters of ultrasonic desilting, such as increasing the frequency and power of the ultrasonic wave, and setting an appropriate duration. Subsequently, the human-computer interaction system 6 sends a command to the ultrasonic generator 4 to control the ultrasonic transducer 2 to emit desilting ultrasonic waves to clean the silted area.

[0049] Step 4: Feedback and maintenance. After the desilting operation is completed, the pipeline detection and anti-blocking component 3 performs another detection to evaluate the desilting effect. If the detection result shows that the pipeline wall thickness has reached the preset standard, it indicates that the desilting is successful; if it does not reach the preset standard, the ultrasonic parameters are adjusted through the human-computer interaction system 6 to repeat the desilting operation. At the same time, the user regularly checks the operating status of the system through the remote monitoring module 7, makes necessary parameter adjustments, and handles any new alarm information. In addition, the pipeline detection and anti-blocking component 3 is regularly maintained and serviced to ensure its long-term stable operation.
