Oil and gas pipeline high consequence area management system and method

Abstract

The embodiment of the invention provides an oil and gas pipeline high-consequence area management system and method. The system comprises a high-consequence region management module which comprises ahigh-consequence region data management unit which is used for receiving the data of a pipeline high-consequence region sent by a client and maintaining and updating the data of the high-consequence region; a high-consequence region identification management unit which is used for processing the received data of the high-consequence region of the client pipeline according to a certain preset ruleand identifying the high-consequence region; a high-consequence region evaluation management unit which is used for evaluating and grading the high-consequence region identified by the high-consequence region identification management unit and managing a grading result; and a high-consequence region management decision unit which is used for performing management decision on the high-consequence region identification result and the grading result, specifying different high-consequence region management measures and improving the safety and economy of the pipeline management.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of risk management of oil and gas pipelines, and in particular to a management system and method for high consequence areas of oil and gas pipelines. Background technique [0002] In the past ten years, my country's natural gas industry has developed by leaps and bounds, which has promoted the adjustment of the national energy structure and industrial structure. The construction of natural gas pipelines has also developed rapidly. Under the situation that the natural gas pipeline network does not need to be extended, there are more and more threats to the safety of pipeline network facilities and gas transmission. Ensuring the safe operation of natural gas pipelines has become a natural gas industry. Industrial focus. Therefore, it is an urgent task to strengthen the risk management of natural gas pipelines, especially for high-consequence areas. [0003] Pipeline high-consequence...

AI Technical Summary

Problems solved by technology

The enterprise standard "Pipeline Integrity Management Specifications" issued by PetroChina establishes quantitative scoring criteria for the management of high-consequence areas of oil and gas pipelines, but the criteria are limited and quantified, which affects the use effect

[0005] According to the analysis results of the identification report of high-consequence areas that have been formed in long-distance pipelines, the definition of high-consequence areas is unclear, and there are misjudgments and misidentification areas; Correct classification; the description language of high-consequence features is not standardized, for example, there are multiple description methods such as highway crossing, highway crossing, highway crossing, highway companionship, etc.; The scoring values ​​are not the same; there are errors in the statistical results, such as the description of high-consequence features in the report is not completely consistent with the scoring table; the level of written and language descriptions of the reporters is uneven; the formed reports are not standardized; the preventive measures taken in different risk areas are similar ; The risk assessment plan formulated is not detailed, and the basis for implementing the risk assessment is vague, resulting in inaccurate risk assessment results, etc.

In addition, in the process of identifying and counting high-consequence areas, affected by the identification conditions and the knowledge level of the identifyrs, the error of the identification process and identification results is greatly affected by human factors, the process is lengthy, and the identification results cannot be effectively used in the identification process of the next year

[0006] The existing technology for the identification and evaluation of high-consequence areas makes the classification imprecise, making the reliability of the identification results and the guidance for management unsatisfactory

[0007] In addition, at present, oil and gas pipeline companies have not established a relatively complete and comprehensive information sharing and interaction platform for the management of high-consequence areas. The data and information of pipeline high-consequence areas are often managed manually, which is not accurate enough and not updated in time.
