摘  要:
基于羽流的相关假设及理论,采用求解积分控制方程的方法,建立了含油污水排放近区污染扩散的数值模型。将该模型应用于陆丰13-1平台附近含油污水水下60m排放的输移扩散预测,并利用UM3软件验证结果的可信性,预测结果给出了污水石油烃中心浓度的运动轨迹及不同浓度石油烃在垂向不同深度上所能到达的最大水平距离和影响面积,结果显示,表层石油烃最高浓度为0.41mg/L,无超四类水质海域;超一(二)类水质的最大水平距离为34.92m,最大面积为1826.69m2。

摘  要:
Based on the assumptions and theories related to the plume,a numerical model is established to simulate the spread of oil sewage in the near field by solving the integral control equation.This numerical model is applied to Lufeng 13-1platform in order to predicate the trajectory of the oil sewage and the maximum distance and the area that the oil will affect in different water layers.The simulation results show that:the highest concentration of petroleum hydrocarbons in the surface layer is 0.41mg/ L,which is consistent with the four-class water quality.The max area which exceeds one-class and two-class water quality is 1826.69m2,and the max distance away from the discharge point is 34.92km.
