Description
Technical Field
[0001] This invention relates to the field of protection system technology, and in particular to a triple protection system and method for pipeline crude oil leakage. Background Technology
[0002] Most pipeline crude oil leakage protection systems establish an external control system for the pipeline, which can effectively prevent, detect and respond quickly to crude oil leakage events, ensure environmental and production safety, and prevent major accidents when pipelines leak, thereby greatly improving the safety of pipeline use.
[0003] Traditional protection systems often rely on post-accident response measures, lacking proactive prevention and real-time monitoring capabilities. This results in the system being unable to react promptly when crude oil leaks occur, often only being discovered after damage has already been done. Traditional security equipment, such as electronic fences and vibration fiber optic cables, is easily affected by environmental factors, such as weather conditions like wind, frost, rain, dew, and snow, significantly reducing monitoring effectiveness. Furthermore, these devices have limited observation distances, potentially failing to cover the entire pipeline and creating blind spots. After prolonged operation, traditional security equipment experiences high aging rates, leading to false alarms and missed alarms, increasing maintenance costs and potentially causing delays or ineffective emergency responses. Traditional systems also lack advanced intelligent analysis algorithms and models, hindering in-depth mining and analysis of pipeline operation data, thus failing to accurately identify potential anomalies or risks.
[0004] Therefore, in response to the problems that the aforementioned protection systems cannot react in time when crude oil leaks occur, and that traditional security equipment such as electronic fences and vibration optical cables are easily interfered with by environmental factors, resulting in a significant reduction in monitoring effectiveness, inability to cover the entire pipeline, and the existence of monitoring blind spots, as well as the lack of advanced intelligent analysis algorithms and models to deeply mine and analyze pipeline operation data, a triple protection system and protection method for pipeline crude oil leaks that can be efficiently designed can be proposed. Summary of the Invention
[0005] To overcome the problems of lack of proactive prevention and real-time monitoring capabilities in protection systems, the susceptibility of security equipment such as electronic fences and vibrating fiber optic cables to interference from environmental factors, and the lack of advanced intelligent analysis algorithms and models, which prevent in-depth mining and analysis of pipeline operation data.
[0006] The technical solution of this invention is: a triple protection system for pipeline crude oil leakage, which includes a maintenance and prevention module, a real-time monitoring module, a data analysis and processing module, and an emergency protection module; wherein, The maintenance and prevention module includes a reinforced design and construction unit for selecting high-quality, corrosion-resistant materials and optimizing pipeline layout to avoid crossing environmentally sensitive areas, a pipeline maintenance unit, an employee training unit, and a data preprocessing unit.

[0008] Preferably, the inspection instruments in the pipeline maintenance unit can include ultrasonic crack detectors, magnetic flux leakage intelligent pigs, pipeline corrosion rate detectors, pipeline leak detectors, pipeline magnetic particle detectors, and pressure testers. Ultrasonic crack detectors can use ultrasonic waves to detect and locate cracks and pores caused by corrosion within the pipeline wall, assessing and diagnosing risks. Magnetic flux leakage intelligent pigs can detect changes in pipeline wall thickness and dents caused by corrosion inside and outside the pipeline. Pipeline corrosion rate detectors can detect the degree of corrosion on the inner wall of the pipeline using a detector and display the results on the instrument's screen. Pipeline leak detectors can detect leaks in the pipeline system, including leaks at pipe joints and connections, as well as leaks inside the pipeline. Pipeline magnetic particle detectors apply magnetic powder to the pipeline surface and then use a magnetic field to attract the powder, thus revealing cracks and defects on the pipeline surface. Pressure testers can measure the pressure in the pipeline to determine whether a leak exists, and the location and size of the leak.
[0009] Preferably, the sensing installation unit may also include a sound detector for sensing pressure changes and sounds generated inside the pipeline. By monitoring the sounds, real-time monitoring and detection of the pipeline's operating status can be achieved.

[0011] Preferably, the data analysis and processing module also includes a data assessment unit for evaluating pipeline leakage risk, in order to assess whether there is a leakage risk and the risk level of the pipeline. When the risk level is high, the early warning unit will be automatically activated to provide timely warning.
[0012] Preferably, the leak source cutoff unit can activate an emergency shut-off valve to quickly cut off the leak source in an emergency.

[0014] As a preferred approach, after the emergency protection module is completed, the emergency response can be summarized and analyzed, and improvement suggestions can be made to continuously improve and optimize the emergency response system and enhance the level of future emergency management.
[0015] The triple protection method for pipeline crude oil leakage includes the pipeline crude oil leakage triple protection system as described above, and its steps are as follows: Step 1: First, in the pipeline design phase, select corrosion-resistant and high-strength materials, optimize the pipeline layout, and avoid crossing environmentally sensitive areas. During construction, strictly implement quality standards to ensure the quality of key processes such as welding. Use ultrasonic crack detectors, magnetic flux leakage intelligent pipeline pigs, pipeline corrosion rate detectors, pipeline leak detectors, pipeline magnetic particle detectors, and pressure testers to regularly inspect the pipeline, promptly identify and repair potential hazards, strengthen inspections along the pipeline route to prevent third-party damage, and enhance employee safety education and training to improve their awareness and response capabilities to crude oil leakage risks. At the same time, establish and improve safety management systems, clarify the responsibilities and obligations of personnel at all levels, and play a first-level protective role. Step 2: During pipeline installation, temperature sensors, pressure sensors, flow sensors, liquid level sensors, gas concentration sensors, and infrared radiation thermometers are installed along the pipeline to monitor the pipeline's operating status in real time. The analog signals collected by these sensors are transmitted to a data acquisition unit and then collected in a data processing center. The data is analyzed and processed by a high-efficiency analysis unit. In the event of any data anomaly, an audible and visual alarm device is immediately activated, providing a double protection effect. Step 3: When a leak occurs, immediately activate the emergency activation unit, handle the situation according to the established procedures, establish an emergency communication network, and be responsible for controlling and coordinating the actions of each emergency team to ensure the efficient implementation of the emergency response. Determine the specific location of the leak source through the sensor installation unit and activate the valve shut-off device to cut off the leak source. Step 4: Set up a dike around the leak area to prevent the leaked material from spreading. Then, start the oil suction machine and oil-water separator to contain and recover the leaked crude oil. Next, sample and analyze the contaminated area to assess the degree and extent of the pollution. Based on the assessment results, develop a targeted environmental remediation plan to achieve the purpose of triple protection.
[0016] The beneficial effects of this invention are: 1. This system, through its maintenance and prevention module, reduces the risk of crude oil leaks at the source. Utilizing high-quality, corrosion-resistant materials and optimizing pipeline layout to avoid traversing environmentally sensitive areas significantly reduces the likelihood of leaks caused by material aging and environmental factors. Regular pipeline maintenance and hazard repair further ensure safe pipeline operation. The real-time monitoring module can perceive the pipeline's operating status in real time. Multiple sensors installed along the pipeline can monitor various parameters in real time. Once an anomaly is detected, the early warning unit will immediately issue an audible and visual alarm, enabling relevant personnel to quickly be informed and react. This real-time monitoring and rapid response mechanism greatly shortens the response time to leak events and reduces losses. The data analysis and processing module uses advanced data analysis algorithms and models to analyze the pipeline... In-depth mining and analysis of operational data can identify potential anomalies or risk points. This not only provides a scientific basis for the safe operation of pipelines but also provides strong support for the decision-making of the emergency protection module. Through data analysis, the system can more accurately judge the development trend and impact range of leakage events, providing more effective guidance for emergency response. The emergency protection module includes multiple sub-modules such as emergency activation unit, command execution unit, leak source cut-off unit, containment and recovery unit, and repair unit, forming a comprehensive emergency response mechanism. When a leakage event occurs, the system can quickly activate the emergency plan and mobilize various emergency teams to carry out coordinated operations. Through measures such as cutting off the leak source, containing and recovering leaked crude oil, and repairing contaminated areas, the system can effectively control the spread and impact range of leakage events, reducing damage to the environment and ecology. 2. The employee training unit in this system improves employees' awareness and response capabilities regarding crude oil spill risks by establishing and improving safety management systems and strengthening employee safety education and training. This not only helps employees strictly abide by safety regulations and operating procedures in their daily work, reducing leaks caused by human factors, but also helps them react quickly and accurately and take effective measures to deal with leaks. By reducing the occurrence of crude oil spills and mitigating their environmental impact, the system helps protect the ecological environment and promote sustainable development. Through timely containment, recovery, and remediation, the system can reduce the pollution and damage of leaked crude oil to soil, water sources, and the ecosystem. Optimizing pipeline layout and using high-quality materials to reduce leak risks helps reduce the likelihood of future leaks. Attached Figure Description

In emergencies, the leak source cutoff unit can activate an emergency shut-off valve to quickly cut off the leak source. The containment and recovery unit sets up a dike around the leak area to prevent the spread of leaked material, and then activates an oil suction machine and an oil-water separator to process the leaked crude oil. The containment and recovery remediation unit involves sampling and analyzing the contaminated area to assess the degree and extent of pollution. Based on the assessment results, a targeted environmental remediation plan is developed. The remediation unit can utilize gas chromatography and liquid chromatography to analyze the types and concentrations of pollutants.

After the emergency protection module is completed, the emergency response can be summarized and analyzed, and improvement suggestions can be proposed to continuously improve and optimize the emergency response system and enhance future emergency management capabilities.
[0027] The triple protection method for pipeline crude oil leakage includes the pipeline crude oil leakage triple protection system as described above, and its steps are as follows: Step 1: First, in the pipeline design phase, select corrosion-resistant and high-strength materials, optimize the pipeline layout, and avoid crossing environmentally sensitive areas. During construction, strictly implement quality standards to ensure the quality of key processes such as welding. Use ultrasonic crack detectors, magnetic flux leakage intelligent pipeline pigs, pipeline corrosion rate detectors, pipeline leak detectors, pipeline magnetic particle detectors, and pressure testers to regularly inspect the pipeline, promptly identify and repair potential hazards, strengthen inspections along the pipeline route to prevent third-party damage, and enhance employee safety education and training to improve their awareness and response capabilities to crude oil leakage risks. At the same time, establish and improve safety management systems, clarify the responsibilities and obligations of personnel at all levels, and play a first-level protective role. Step Two: During pipeline installation, temperature sensors, pressure sensors, flow sensors, liquid level sensors, gas concentration sensors, infrared radiation thermometers, and sound detectors are installed along the pipeline to monitor its operating status in real time. The analog signals collected by these sensors are transmitted to a data acquisition unit and then collected in a data processing center. The data is analyzed and processed by a high-efficiency analysis unit. In case of data anomalies, an audible and visual alarm is immediately activated. The data can also be evaluated to assess whether there is a risk of leakage in the pipeline and the risk level. When the risk level is high, the early warning unit will be automatically activated to provide timely warnings. The early warning unit may also include a monitoring display screen that displays the pipeline operating status, data analysis results, and early warning information in real time, providing intuitive visual support for management personnel. It may also include walkie-talkies, telephones, mobile phones, etc., for instant communication between on-site personnel and the monitoring center, ensuring rapid transmission of early warning information and rapid activation of emergency response, providing a double protection effect. Step 3: When a leak occurs, immediately activate the emergency activation unit, handle the situation according to the established procedures, establish an emergency communication network, and be responsible for controlling and coordinating the actions of each emergency team to ensure the efficient implementation of the emergency response. Determine the specific location of the leak source through the sensor installation unit and activate the valve shut-off device to cut off the leak source. Step 4: Set up a dike around the leak area to prevent the leaked material from spreading. Then, start the oil suction machine and oil-water separator to contain and recover the leaked crude oil. Next, sample and analyze the contaminated area to assess the degree and extent of the pollution. Based on the assessment results, develop a targeted environmental remediation plan to achieve the purpose of triple protection.
[0028] Through the above steps, this protection system effectively prevents crude oil leaks by selecting high-quality materials, optimizing pipeline layout design, and conducting regular inspections and maintenance. Simultaneously, the real-time monitoring module can perceive the pipeline's operating status in real time and promptly detect anomalies. The data analysis and processing module utilizes advanced data analysis algorithms and models to deeply mine and analyze pipeline operating data, identifying potential anomalies or risk points. The emergency protection module can automatically activate emergency plans and execute corresponding operations when a leak occurs. This addresses the problems of protection systems lacking proactive prevention and real-time monitoring capabilities, security equipment such as electronic fences and vibration optical cables being easily affected by environmental factors, and the lack of advanced intelligent analysis algorithms and models that prevent in-depth mining and analysis of pipeline operating data.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
