针对油气管道安全设计中需要关注的问题,结合沙特阿美油气管道安全设计规范SAES-B-064—2017《陆上及近海管道安全》的最低强制性安全要求,对比国内GB 50251—2015《输气管道工程设计规范》等规范，探讨了油气管道设计过程中关于地区等级划分、阀室设置等问题。沙特阿美油气管道安全设计规范对主要安全问题提出了明确的定量设计要求,具有较强的可执行性。结合沙特阿美规范的规定和国内规范在工程实践中遇到的问题,分析了国内外规范在地区等级划分、阀室设置等规定的差异和优缺点,并对国内规范相关规定提出了修改完善的建议,有助于提高规范设计层面的执行性并对管道完整性管理提供进一步保障。

In relation to the safety in design of oil and gas pipelines that needs attentions, taking into consideration the relevant minimum mandatory safety requirements for the design of onshore pipelines of the Saudi Aramco engineering standard SAES-B-064—2017 Engineering Standard-Onshore and Nearshore Pipeline Safety, and by comparing with Chinese national standard such as GB 50251—2015 Code for Design of Gas Transmission Pipeline Engineering, this paper discusses the engineering design of oil and gas pipeline location class and block valve station. Saudi Aramco engineering standards of pipeline safety design puts forward clear quantitative design requirements for major safety issues, which are more pragmatic and easier to implement. Taking into consideration the Saudi Aramco engineering standards requirements and the problems encountered in application of domestic codes and engineering practices, this paper analyses the differences, advantages and disadvantages in the determination of location class and block valves station are analyzed, and provide suggestions on revising and updating relevant regulations of Chinese national standard and standards. The suggestion aims to help improving the implementation of standard regulations at the design level and provides further guarantee for the pipeline integrity management.
