怒江激流型河流溢油控制技术
Oil spilling control technologies used for torrent-type rivers: a case study on Nujiang River
-
摘要: 中缅原油管道穿跨越4条国际性河流, 对溢油控制技术的研究尤为重要。通过分析围油栏种类及布放方式, 提出了不同工况下围油栏干舷和栏裙高度的选择范围, 给出了水流速度、围油栏最大布放角及受力的计算方法, 并提供了多种围油栏布放方案。怒江汛期最大水流速度可达3.6 m/s, 国产激流型围油栏仅适用于怒江枯水季节, 汛期时仍无法布放成功, 结合怒江溢油控制实例, 测得国内某激流型围油栏实测最大布放角度及受力数据, 为进一步研究激流型河流溢油控制技术提供了参考。Abstract: The China-Myanmar Crude Oil Pipeline runs across 4 international rivers, and it is quite important to study oil spilling control technologies. In this paper, the types and laying modes of oil boom were analyzed. Then, the selection ranges of the freeboard and skirt height of oil boom under different working conditions were put forward, and the methods to calculate the velocity of flow and the max laying angle and stress of oil boom were provided. In addition, multiple oil boom laying schemes were described. In the Nujiang River, the maximum flow velocity in high-water seasons is up to 3.6 m/s and the domestic torrent-type oil booms can only be applicable in low-water seasons and cannot be laid successfully in highwater seasons. Finally, based on the case of oil spilling control in the Nujiang River, the maximum laying angle and stress data of a certain domestic torrent-type oil boom were measured. The research results provide the reference for the studies on oil spilling control technologies used for torrent-type rivers.
