海底输油管道泄漏扩散演化预测模型研究
Research on prediction model of diffusion and evolution of oil spills from subsea oil pipelines
摘要
Abstract
To investigate the diffusion characteristics of leaked oil in marine environments,an oil spill prediction model was presented based on plume dynamics and particle tracking methods.The comprehensive simulation and prediction of the leaked oil from the leakage point to the seawater and subsequently to the sea surface were achieved by solving the underwater oil spill diffusion and sea surface oil evolution processes.The current and wind fields of a specific region in the South China Sea were incorporated into the oil spill prediction model.Leakage characteristic parameters were set,and the evolution characteristics of the oil spill in the region were simulated.Prediction results show that the underwater diffusion range of the oil spill is approximately 200 m,while the diffusion range of the surface oil slick is much larger than that underwater due to the influence of the wind.By 36 h,the drift distance of the oil slick has reached over 20 km.A significant linear positive correlation is observed between the surface diffusion coefficient and the spreading rate of the oil slick.By adjusting the surface diffusion coefficient and other leakage characteristic parameters(leakage aperture and leakage velocity),the model can effectively predict the underwater and surface evolution processes of leaked oil under any leakage conditions,providing theoretical support for emergency response to leakage accidents.关键词
