油气长输管道沿线经过的地形复杂多变,甚至不可避免地要穿越环境敏感点,如果管道发生泄漏事故,就会对环境产生不良影响。本文通过对国内外长输管道泄漏事故的统计、分析,确定了泄漏事故的主要影响因素,得出了综合分析结论,为国内管道的穿越工程的管理提供了借鉴。 The topography along the long-distance pipeline of oil and gas is complicated and changeable, and it is inevitable to even cross the sensitive point of the environment. If the pipeline leaks, it will have an adverse impact on the environment. Through the statistics and analysis of the long-distance pipeline leakage accidents at home and abroad, the paper determines the main influencing factors of the leakage accidents and obtains the conclusion of the comprehensive analysis, which provides a reference for the management of the cross-country pipeline projects in China.
