- 近年来,随着冻土区油气资源的开发和利用,冻土区管道运输受到越来越多地关注。由于冻土区域地质与环境的特殊性,对管道运行具有严重的不利影响,因此,对冻土区域的油气管道事故进行分析显得尤为重要。对近年来美国与加拿大输油气管道事故进行数据统计与分析,比较冻土区与非冻土区管道事故的区别与联系；参考相关文献,将冻土区管道事故原因分为7类：融沉、冻胀、冰堵、露管、地震、滑塌、洪水。对此数据进行统计与分析为我国冻土区的油气管道事故分析、应急处理、风险管理等提供参考,也为冻土区管道的设计、施工及其冻害防治等提供科学依据。
In recent years, with the development and utilization of oil and gas resources in permafrost areas, pipeline transportation in permafrost areas is also getting more and more attention. Due to the particularity of the geology and environment in the permafrost area, it has a serious adverse effect on the pipeline operation. Therefore, it is very important to analyze the oil and gas pipeline accidents in permafrost areas. In this paper, the data statistics and analysis of the oil and gas pipeline accidents in the United States and Canada in recent years have been carried out and the comparison for the difference and connection of pipeline accidents in permafrost and non-permafrost areas has been performed. According to related literature, the causes for pipeline accident in the permafrost areas are divided into the following reasons: thawing settlement, frost, ice block, dew tube, earthquake, slump, flooding. This provides a reference to accident analysis, emergency processing and risk management of oil and gas pipeline in permafrost areas and scientific basis to the design, construction of pipeline and damage prevention in permafrost areas.
