- 摘要:
- GB 32167—2015《油气输送管道完整性管理规范》已颁布实施多年,各管道企业均按照该规范开展管道的高后果区识别和分级。由于该规范中高后果区分级标准多是定性描述,而不是定量描述,因此在实际工作应用中存在不同企业、不同技术人员对同一个高后果区的划分级别不同的问题。结合管道实际应用情况,在该规范中高后果区分级标准的基础上,将户数折算为人数,提出新的高后果区分级方法，即按照管道影响范围内人数划分高后果区级别,并制作新的高后果区分级表。新的高后果区分级方法定量描述高后果区级别,标准明确,简单科学,便于实际操作应用,既解决了特定场所高后果区分级标准不统一的问题,也解决了输气管道按照地区等级划分高后果区级别不合理的问题。
研究结果可为油气输送管道高后果区识别和级别划分提供参考，为GB 32167—2015《油气输送管道完整性管理规范》的修订提供依据。
The GB 32167—2015 Oil and Gas Pipeline Integrity Management Specification has been promulgated and implemented for several years and various pipeline companies apply this standard in identification and determination of high-consequence areas. As with most standards, the descriptions in this standard are qualitative rather than quantitative. This results in a problem in actual application that different companies and different technical personnel have inconsistent interpretations of the same high-consequence areas. On the basis of the original standard and incorporating experience on the actual application on transmission pipelines, the number of households is converted into the number of people, and a new method of classifying the level of high-consequence area according to the number of people in the pipeline’s affected area is proposed, together with a table for high-consequence classification prepared to assist in consistent interpretation. Based on simple and scientific approach, this new method presents a quantitative definition for the level and extent of high-consequence area, which is easy to apply on actual field operation. This approach resolves the issue of inconsistent classification standards for high-consequence areas in specific locations as well as unreasonable classification of high-consequence areas in gas pipelines according to regional levels. The study result presented in this paper could provide useful references for the identification and classification of high-consequence areas for oil and gas transmission pipelines and provide basis and data for future revisions of GB 32167—2015.
