渤海湾蓬莱19-3油田漏油问题的仿真与决策

Simulation and Decision of Oil Leakage Problem in Penglai 19-3 Oilfield, Bohai Bay

摘要: 蓬莱19-3油田漏油事故严重影响了海洋经济与生态发展，海洋保护问题再一次成为社会热点话题。本文首先针对渤海石油泄漏的问题，借助物理中受力分析和流体力学控制方程，分别考虑在平静海平面上、受到自身重力和某种外在因素影响、受到洋流和风力影响下油膜状态，并利用计算机MATLAB程序仿真建立了溢油扩散的数学模型，反映溢油的扩散规律。其次，利用几何图形模拟实际场景，分析上述三种情况下的漏油点的确定方法。最后进行最优决策，确定需要建立的最佳监测点位置及个数，将溢油对海洋生态的损失降到最低。

Abstract: The oil leakage accident in Penglai 19-3 oilfield has seriously affected the Marine economy and ecological development, the Marine protection issue has once again become a hot topic in society. This paper first addresses the problem of oil leakage in Bohai Sea, with the help of physical force analysis and hydrodynamic control equations, respectively considers the oil membrane state at the calm sea level, under its own gravity and some external factors, under the ocean current and wind influence. The mathematical model of oil spill diffusion is established by using computer MATLAB program and reflects the diffusion law of the oil spill. Secondly, the geometry is used to simulate the actual scene and analyze the determination method of oil leakage points in the above three scenarios. Finally, the optimal decision is made to determine the optimal location and number of monitoring points to be established, so as to minimize the loss of oil spill to Marine ecology.
