鉴于目前的溢油模型主要是针对海面溢油的情况,本文提出了预测海底管道出现裂纹和腐蚀形成的小孔时发生溢油的模型。预测在海底管线上某一位置处的蠕孔漏油后,油的浓度超过某一规定浓度的范围,海面上形成油膜的起始位置,估计油膜是否能到达海岸线,以及被风浪携带到海岸线上的原油量。本文还给出了一个基于渤海自然状况及原油性质的算例。结果表明,该模型可以为海底管线上蠕孔溢油的污染情况预测提供参考。
In view of the fact that the current oil spill model is mainly aimed at the oil spills on the sea surface, a model for predicting oil spills when predicting cracks and corrosion in the submarine pipelines is proposed. It is predicted that after the oil leakage in the creep hole at a certain position on the subsea pipeline exceeds a certain concentration range, the starting position of the oil film formed on the sea surface is estimated whether the oil film can reach the coastline and is carried to the coastline by the storm. The amount of crude oil. This article also gives an example based on the nature of the Bohai Sea and the nature of crude oil. The results show that the model can provide reference for the prediction of the pollution of the creeping oil in the submarine pipeline.
