| 摘 要： | 通过采用不规则的三角网格和有限体积法的FVCOM模式,建立三维潮流数值模型。利用大海域计算得到的调和常数值作为开边界的输入值,模拟出崖城附近海域的潮流和潮位变化情况。在潮流、潮位验证正确的前提下,利用欧拉—拉格朗日追踪方法,建立了溢油轨迹预测模型,进行崖城油气田附近海域溢油中心轨迹的预测,同时预测了溢油漂移的平均速率和油膜抵达敏感区的时间,为油气田实施应急措施提供技术支持。

| Abstract: | Based on the unstructured grid finite-volume coastal ocean model(FVCOM),the complete three-dimensional fine-solution equation group of shallow-sea tide is used to compute the tidal current and sea-level variations in Yacheng sea area.The open boundary conditions are provided by the open oceanic model.The simulation of the tidal current and sea-level are verified with the observation data.By Euler-Lagarangian tracing method,a trajectory forecasting model for spilled oil is established to predict the trajectory of the oil-film centre,the averaging moving rate and the reaching time of the oil to the sensitive area in Yacheng oil and gas field sea area.It offers some effective technologies for the emergency response to the oil and gas field. |
