Oil-gas pipeline high-consequence area identification system and identification method

Abstract

The invention discloses an oil-gas pipeline high-consequence area identification system and identification method. The identification system comprises an oil conveying pipeline high-consequence area identification subsystem and a gas conveying pipeline high-consequence area identification subsystem. The oil conveying pipeline high-consequence area identification subsystem comprises oil conveying pipeline high-consequence area total-risk contribution value computing unit and an oil conveying pipeline high-consequence area judging unit. The gas conveying pipeline high-consequence area identification subsystem comprises a gas conveying pipeline high-consequence area total-risk contribution value computing unit and a gas conveying pipeline high-consequence area judging unit. According to the identification method, existing subjective and extensive identification methods at home and abroad are abandoned, various factors influencing pipeline leakage are taken into consideration comprehensively, the systematic identification system is set up, the calculation thought and the method are simple, the site fitness of the analysis result is good, high-consequence pipe sections of different types of a whole pipeline can be identified, and engineering technical personnel can work out the scientific countermeasures according to the situations of the pipe sections.

Description

technical field [0001] The invention relates to the technical field of pipeline risk management, in particular to an identification system and an identification method for high-consequence areas of oil and gas pipelines. Background technique [0002] In recent years, many oil and gas pipelines in my country have been put into operation one after another, and the number is increasing rapidly. Their safe operation plays a decisive role in the development of national life and economy. However, it is not difficult to find that long-distance oil and gas pipelines (such as most of the oil and gas pipelines in the Sichuan-Chongqing region, the Qinjing crude oil pipeline, the Lanchengyu refined oil pipeline, the Shaanxi-Beijing gas pipeline, the West-East gas pipeline, the China-Kazakhstan pipeline, and some The common features of the proposed pipelines are: the pipelines cross a wide area, the external environment is complex, there are many hidden dangers of accidents, and the cons...

AI Technical Summary

Problems solved by technology

[0005] The current high-consequence identification of pipelines in China is mainly considered from two aspects of population and buildings. They are all limited to simple division and list scoring of high-consequence areas, lacking a systematic identification system, operability of the method, and accuracy of identification results. Sexuality and guidance to management are not satisfactory
