Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas transportation, and in particular to a pipeline risk early warning system. Background Art

[0002] With the continuous acceleration of the construction of the national oil and gas transmission network, the external environment for pipeline construction and operation has become increasingly complex and changeable.

[0003] On the one hand, long-distance oil and gas pipelines traverse remote areas, creating management challenges and creating blind spots in monitoring, making it difficult to quickly identify potential damage risks. Fiber-optic early warning systems, capable of providing wide-area, all-weather pipeline safety awareness, provide early warning of unexpected construction activities around pipelines. Furthermore, fiber-optic early warning systems are linked to video surveillance in high-consequence areas, enabling remote monitoring and voice warnings, further improving pipeline patrol efficiency.

[0004] On the other hand, although the internal inspection data of oil and gas pipelines can effectively support the safety assessment of pipelines, the pipeline defect data given by the internal inspection assessment is not reflected in pipeline protection. The key measure of strengthening safety protection within the scope of pipeline defects cannot be effectively linked with fiber optic early warning.

[0005] In view of this, how to effectively connect oil and gas pipeline detection and fiber optic early warning and realize data sharing and business integration is of vital importance to improving the risk warning capabilities and operational safety of the entire pipeline.

[0061] Figure 2 This is a flow chart of a pipeline risk early warning method provided in this embodiment. DETAILED DESCRIPTION

[0062] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0063] Fiber-optic vibration early warning: This service utilizes fiber-optic vibration sensors installed along pipelines to provide real-time monitoring and early warning of external construction activities that could threaten pipeline safety. Once an abnormal vibration signal is detected, an early warning process is automatically triggered, notifying inspectors to conduct on-site review or remote verification using drones, cameras, and other equipment to ensure pipeline safety. This service is designed to improve the response speed and accuracy of pipeline protection.

[0064] In-line inspection: An advanced inspection technology, in-line inspection utilizes pipeline media to propel pipeline detectors, detecting and recording damage such as deformation and corrosion, while accurately locating defects. Given that oil and gas pipelines are often laid underground, in-line inspection can proactively identify potential defects and damage, assessing the risk level of each pipeline section. This is crucial for preventing accidents, reducing losses, and saving maintenance costs, and is an indispensable means of ensuring safe pipeline operation.

[0065] Pipeline Risk Warning: Relying on advanced monitoring technology, this system provides timely warnings of potential pipeline damage. Once the system issues an alert, inspectors can respond quickly, arriving on-site for immediate review and resolution, effectively preventing the situation from escalating, minimizing potential impacts and losses, and ensuring safe and stable pipeline operations.

[0066] The pipeline risk warning system proposed in an embodiment of the present invention deeply integrates and analyzes internal inspection and fiber optic warning to provide high-priority attention and management suggestions to inspection personnel. This achieves the deep integration and efficient utilization of internal inspection and fiber optic warning, providing a more accurate and efficient pipeline risk warning and management solution for long-distance oil and gas pipeline companies.

This information is then synchronized with the fiber-optic warning module, enabling the warning system to automatically update and dynamically manage high-risk areas. This system comprehensively improves the effectiveness of pipeline risk monitoring and provides a solid foundation for the safety of long-distance pipelines.

[0113] Example 2

[0114] This embodiment provides a pipeline risk early warning method, which is implemented based on the pipeline risk early warning system described in Example 1. The process is as follows: Figure 2 Shown, including:

[0115] Real-time monitoring and data archiving: After the pipeline detector completes a comprehensive internal inspection defect analysis, the pipeline internal inspection management module automatically archives the results. By continuously monitoring the internal inspection results, the real-time and accuracy of the data is ensured.

[0116] Defect screening and status marking: Based on pre-set rules and algorithms, the system filters out defect information from internal inspection results. At the same time, it marks the screened defect information and sets its status to "uninspected" for subsequent tracking and processing.

[0117] Defect Classification and Risk Assessment: We further analyze the identified high-risk defects and classify them based on their scope and depth. These defects are categorized as high-risk or general-risk, providing a valuable basis for risk assessment and early warning.

[0118] Zone Information Update and Synchronization: The pipeline risk warning module regularly obtains the latest zone information from the fiber optic warning module. Zone information generally includes the zone's location and consequence level. The consequence level is categorized as high-consequence or medium-consequence. Updated zone information is synchronized with the in-pipeline detection module to ensure consistency and timeliness.

[0119] Defect Data Update and Merge: The pipeline risk warning module updates existing defect information based on real-time defect information synchronized from the pipeline inspection management module. Defects are categorized and matched to corresponding defense zones based on their mileage location. During this matching process, the highest risk level is adhered to, ensuring that the risk level within the defense zone reflects the highest risk status.

[0120] Risk zone division and conversion: The pipeline risk warning module categorizes the defect zones based on the risk zone division rules of the fiber optic warning module. These zones are divided into high-risk, general-risk, and non-risk zones, providing a foundation for subsequent alarm dispatch and risk management.

[0121] Risk zone information synchronization and push: Using message queue technology, zone classification results are synchronized to the fiber-optic early warning module. The module generates intelligent alarms based on changes in the zone's risk level and provides feedback to patrol personnel, ensuring timely information delivery and response.

[0122] Alarm Scheduling and Status Updates: When the fiber optic early warning module detects a high-risk or general-risk area and no new alarms have been generated within a certain period of time, it intelligently calculates and sends alarms based on the timeframe. At the same time, defects in the pipeline inspection module are marked as "uninspected" to facilitate follow-up action by inspection personnel.

[0123] Regular alarm and review requirements: Within the specified time, the fiber optic early warning module will push regular alarms and send them to the relevant interfaces. After receiving the alarm, the inspection personnel must review the alarm according to the requirements to ensure the accuracy and effectiveness of the alarm information.

[0124] Real-time Alarm and Escalation: When a fiber optic vibration alarm occurs in a high-risk area, the fiber optic early warning module immediately escalates the alarm and limits the time for alarm review. Inspection personnel are required to conduct inspections and reviews within a specified timeframe to ensure prompt response and resolution. The fiber optic early warning module typically has three built-in levels, which are dynamically adjusted.

[0125] Alarm Review and On-site Handling: After receiving an alarm, inspectors must conduct on-site review as required. During the review process, inspectors are required to take photos or videos and upload them, marking the alarm type and the review conclusion. Remote alarm review using drones and remote monitoring is also supported, improving review efficiency and accuracy.

[0126] Review Result Feedback and Status Update: After completing the review, inspectors will feed the results back to the fiber-optic early warning module and synchronize them with the in-pipeline inspection system. Upon receiving the feedback, the in-pipeline inspection system will mark the result in the response field and update the status to "Inspected," ensuring the integrity and accuracy of the information. This result will also serve as an important reference for subsequent risk management and early warning.

[0127] This embodiment addresses the specific requirements of long-distance oil and gas pipeline companies by proposing a solution that aims to achieve more accurate and efficient pipeline risk warning management through the deep integration of fiber-optic early warning and internal inspection technologies. This approach leverages the high sensitivity and real-time nature of fiber-optic early warning. Fiber-optic sensors installed along the pipeline can keenly capture vibration signals caused by external activities such as construction along the pipeline, enabling timely early warnings. This effectively improves the accuracy and relevance of alarms, providing crucial guidance for daily pipeline inspections. Internal inspection, on the other hand, uses precise equipment monitoring and data analysis to comprehensively assess pipeline integrity, directly revealing the type, location, and severity of internal defects, and providing a scientific basis for pipeline repair and maintenance. However, under traditional management models, data silos often exist between the fiber-optic vibration early warning and internal inspection systems, lacking effective data sharing and collaboration mechanisms, limiting the overall effectiveness of risk warning and pipeline management. To address this bottleneck, this embodiment proposes a solution that deeply integrates these two technologies.

[0128] Specifically, by building a data interaction interface and a comprehensive analysis platform, seamless docking and sharing of data between the two systems is achieved. On this basis, advanced data processing and analysis technologies are used to organically combine the real-time nature of fiber optic vibration warning with the accuracy of in-pipeline detection. Not only can the locations of high-risk defects discovered by in-pipeline detection be visually displayed on the map, but the historical alarm data of the fiber optic early warning system can also be combined to dynamically assess the vibration risk and construction risk of the area, providing high-priority attention and management suggestions for inspection personnel. In addition, this embodiment also introduces a comprehensive analysis of defect growth data. By continuously tracking the changing trend of in-pipeline detection data and combining the historical records of the fiber optic early warning system, high-risk risk points in the pipeline are accurately located and dynamically evaluated. This makes pipeline risk warning and management more scientific and systematic, and can effectively improve the safety and efficiency of pipeline operations and reduce the probability and impact of accidents.

[0129] This embodiment aims to build a comprehensive pipeline risk warning system. Through independently configured pipeline risk warning modules, seamless communication between internal detection and fiber optic warning is achieved, ensuring the real-time and accuracy of pipeline monitoring and effectively improving the efficiency of pipeline safety management.

[0130] Internal inspection, a core component, has been enhanced with a real-time monitoring function. After each internal inspection defect analysis, the system can immediately start monitoring the internal inspection results. This function is monitored in real time by a background monitoring program, using pre-set rules to screen out high-risk defects and their locations. Based on specific rules, these screened defects are classified based on both the scope and depth of the defects, clearly distinguishing between high-risk and general-risk defects.

[0131] The pipeline risk warning system is responsible for key functions such as zone update synchronization, defect merging, and risk zone conversion synchronization. It first synchronizes the latest zone information from the fiber optic warning system to ensure its timeliness and accuracy. Subsequently, it updates defects based on real-time defect data synchronized from internal inspections. During the update process, defects are converted based on their mileage location and categorized and merged into the corresponding zone according to the highest risk level, ensuring that the risk level within the zone reflects the highest risk status.

[0132] The fiber optic early warning system implements alarm scheduling, periodic alarms, and real-time alarm functions. It intelligently pushes alarms based on alarm activity within risk areas. If no new alarms are generated within a certain period, the module schedules and pushes alarms, ensuring real-time dispatch. It also pushes regular alarms within a specified timeframe and sends them to relevant interfaces, requiring patrol personnel to review the alarms. For fiber optic vibration alarms in high-risk areas, the system escalates the alarms and limits the time for review, ensuring patrol personnel can immediately conduct patrol reviews.
