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] As the construction of the national oil and gas transmission network continues to accelerate, the external environment for pipeline construction and operation has become increasingly complex and changeable, and the potential threats to oil and gas pipelines have posed a severe challenge to public safety.

[0003] On the one hand, long-distance oil and gas pipelines pass through remote areas, and their management difficulties coexist with monitoring blind spots, making it difficult to quickly identify potential damage risks. In particular, human factors, such as unauthorized excavation and third-party construction activities, have become the main culprits of oil and gas pipeline accidents, seriously threatening the safe and stable supply of national energy. Since fiber-optic early warning can sense pipeline safety over a large area and around the clock, it can provide early warning for sudden construction activities around the pipeline. In addition, fiber-optic early warning is linked to video in high-consequence areas to realize remote monitoring and voice warning functions, 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 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 modes in conjunction with the accompanying drawings.

[0063] Fiber optic vibration warning: referred to as fiber optic warning, it uses fiber optic vibration sensors laid along the pipeline to monitor and warn of external construction activities that may threaten the safety of pipeline operation in real time. Once an abnormal vibration signal is detected, the warning process will be automatically triggered, and the inspection personnel will be notified to go to the site for review, or use drones, cameras and other equipment for remote review to ensure pipeline safety. This service is designed to improve the response speed and accuracy of pipeline protection.

[0064] In-pipeline inspection: In-pipeline inspection is an advanced inspection technology that uses pipeline medium to drive pipeline detectors to detect and record pipeline deformation, corrosion and other damage, and can accurately locate defects. Given that most oil and gas pipelines are laid underground, in-pipeline inspection can detect various potential defects and damages in advance and assess the degree of danger of each pipe section, which is of great significance for preventing accidents, reducing losses and saving maintenance costs, and is an indispensable means to ensure the safe operation of pipelines.

[0065] Pipeline risk warning: Relying on advanced monitoring technology, it aims to timely warn of events that may damage the pipeline. Once the system issues an early warning, the inspection personnel can respond quickly and arrive at the scene for review and processing as soon as possible, thereby effectively preventing the situation from deteriorating, reducing potential impacts and losses, and ensuring the safety and stability of pipeline operation.

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

This system comprehensively improves the efficiency of pipeline risk monitoring and provides a solid guarantee for the basic safety of long-distance pipelines.

[0113] Example 2

[0114] This embodiment provides a pipeline risk early warning method, which is implemented based on a pipeline risk early warning system described in Example 1, and its process is as follows: Figure 2 As 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 will automatically archive 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: According to the pre-set rules and algorithms, the defect information in the internal inspection results is screened out. At the same time, the screened defect information is marked and its status is set to "not inspected" for subsequent tracking and processing.

[0117] Defect classification and risk assessment: Further analysis will be conducted on the selected high-risk defects, and classification will be carried out based on the scope and depth of the defects. The classified defects will be divided into high-risk defects and general risk defects, providing an important basis for risk assessment and early warning.

[0118] Update and synchronization of defense zone information: The pipeline risk warning module regularly obtains the latest defense zone information from the optical fiber warning module. The defense zone information generally includes the location information and consequence level of the defense zone. The consequence level is divided into high consequence area and general consequence area. The updated defense zone information will be synchronized to the pipeline detection module to ensure the consistency and timeliness of the information between the two.

[0119] Defect data update and merging: The pipeline risk warning module updates the existing defect information based on the defect information synchronized in real time by the pipeline inspection management module. According to the mileage location of the defect, the defect is classified and matched to the corresponding defense zone. During the matching process, the highest risk level principle is followed to ensure that the risk level in the defense zone reflects the highest risk status.

[0120] Risk zone division and conversion: The pipeline risk warning module classifies and divides the defense zones to which defects belong according to the risk zone division rules of the optical fiber warning module. The divided defense zones will correspond to high-risk zones, general risk zones and non-risk zones, respectively, providing a basis for subsequent alarm dispatch and risk management.

[0121] Risk zone information synchronization and push: Through message queue technology, the classification results of the defense zone are synchronized to the fiber optic early warning module. The fiber optic early warning module intelligently alarms according to the changes in the risk level of the defense zone and feeds back to the inspection personnel to ensure timely transmission and response of information.

[0122] Alarm scheduling and status update: When the fiber optic early warning module detects that a high-risk area or a general risk area has not generated a new alarm within a certain period of time, it will perform intelligent push calculations and push alarms according to time. At the same time, the defects in the pipeline detection module will be marked as "not inspected" to facilitate subsequent processing by the inspection personnel.

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

[0124] Real-time alarm and upgrade processing: When a fiber vibration alarm occurs in a high-risk area, the fiber early warning module will immediately upgrade the alarm and limit the alarm review time. Inspection personnel need to conduct inspections and reviews within the specified time to ensure that they can respond to and handle alarm events quickly. Generally, the fiber early warning module has three built-in levels for dynamic adjustment.

[0125] Alarm review and on-site processing: After receiving the alarm, the inspectors need to go to the site for review according to regulations. During the review process, the inspectors need to take photos or videos and upload them, and mark the alarm type and review conclusion. At the same time, drones and remote monitoring are supported for remote alarm review to improve review efficiency and accuracy.

[0126] Review result feedback and status update: After completing the review work, the inspection personnel will feedback the review results to the optical fiber early warning module and synchronize them to the pipeline detection system. After receiving the feedback results, the pipeline detection system will mark the results in the response field and update the status to "inspected" to ensure the integrity and accuracy of the information. At the same time, the results will also serve as an important reference for subsequent risk management and early warning.

[0127] This embodiment proposes a solution to the specific requirements of oil and gas long-distance pipeline enterprises, aiming to achieve more accurate and efficient pipeline risk warning management by deeply integrating fiber optic warning and internal detection technology. This method makes full use of the high sensitivity and real-time characteristics of fiber optic warning. The fiber optic sensors laid along the pipeline can keenly capture the vibration signals caused by external activities such as construction along the line, so as to issue warnings in time, effectively improve the accuracy and pertinence of the alarm, and have vital guiding significance for daily pipeline inspections. On the other hand, the internal detection technology comprehensively evaluates the integrity status of the pipeline through precise equipment monitoring and data analysis, directly reveals the type, location and severity of defects inside the pipeline, and provides a scientific basis for the repair and maintenance of the pipeline. However, under the traditional management model, data islands are often formed between the two major systems of fiber optic vibration warning and pipeline internal detection, lacking an effective data sharing and coordination mechanism, which limits the overall effectiveness of risk warning and pipeline management. In order to break this bottleneck, this embodiment proposes a solution that deeply integrates the two major technologies of fiber optic vibration warning and internal detection.

[0128] Specifically, by constructing a data interaction interface and a comprehensive analysis platform, seamless connection and sharing of data between the two systems are 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 found by in-pipeline detection be intuitively displayed on the map, but also the historical alarm data of the fiber optic early warning system can be combined to dynamically evaluate the vibration risk and construction risk of the area, and provide 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 an independently configured pipeline risk warning module, seamless communication between internal detection and optical fiber warning is achieved, ensuring the real-time and accuracy of pipeline monitoring, and effectively improving the efficiency of pipeline safety management.

[0130] Internal inspection is a core component, and a real-time monitoring function has been added. After each internal inspection defect analysis is completed, the internal inspection results can be immediately started and monitored. Real-time monitoring is carried out through the background monitoring program, and high-risk defects and their location information are screened out using preset rules. According to specific rules, the screened defects are classified, and the classification dimensions cover the scope and depth of the defects, so as to clearly distinguish high-risk defects from general risk defects.

[0131] Pipeline risk warning is responsible for key functions such as zone update synchronization, defect merging, and risk zone conversion synchronization. It first synchronizes the latest zone information in the fiber optic warning to ensure the timeliness and accuracy of the information. Subsequently, the defect update operation is performed based on the defect data synchronized in real time by the internal detection. During the update process, the defect is converted according to the mileage position, and the defects are classified and merged into the corresponding zone according to the principle of the highest risk level, thereby ensuring that the risk level in the zone reflects the highest risk status.

[0132] Fiber optic early warning realizes alarm scheduling, regular alarm and real-time alarm functions. It can perform intelligent push calculations based on the alarm situation in the risk area. When no new alarm is generated within a certain period of time, the module will push the alarm scheduling to ensure real-time scheduling. At the same time, it can also push regular alarms within the specified time and send them to the relevant interfaces, requiring patrol personnel to conduct alarm review operations. For fiber optic vibration alarms in high-risk areas, alarm upgrade processing is carried out, and the alarm review time is limited to ensure that patrol personnel can immediately conduct patrol review work.
