陆上输油管道溢油扩散规律及泄漏后果研究进展

输油管道一旦泄漏不但会造成直接经济损失,而且将对周围环境、沿线居民带来不利影响,掌握泄漏油品在周围环境中的渗流、地表扩散以及蒸发情况,对于开展管道应急处理和泄漏后果评价至关重要。结合陆上输油管道泄漏事故特点,从事故条件下的泄漏量、泄漏油品的流动扩散规律以及泄漏后果等方面入手,对成品油管道泄漏油品研究成果进行了归纳总结,同时为进一步研究泄漏油品在周围环境的扩散过程,预估泄漏后果并制定合理的应急处理方案提出了建议。

Progress of research on diffusion rules of spilled oil from onshore oil pipeline and leakage consequences

Oil pipeline leakage will cause direct economic losses and even adversely affect the surrounding environment and residents along the pipeline. It is crucial to be aware of the seepage, surface diffusion and evaporation of leaked oil in the surrounding environment for emergency disposal of pipelines and assessment of leakage consequences. Considering the characteristics of onshore oil pipeline leakage accidents, the research results of oil product pipeline leakage were summarized from the aspects of leakage quantity, flow and diffusion rules of the leaked oil under accident conditions and leakage consequences. Additionally, suggestions were proposed for further studying the diffusion process of the leaked oil in surrounding environment, estimating the leakage consequences and developing reasonable emergency disposal schemes.
