    摘要
  • 摘要: 对海冰的运动规律进行精确、连续和长周期的实时监测有助于海冰热力学和动力学的研究,也可保障冰区生产活动的安全进行。针对辽东湾海冰的运动特点和工程需求,在JZ20-2油气平台上建立了海冰雷达监测系统。采用数字图像处理技术对海冰雷达监测图像进行了分析和软件开发,可对海冰密集度、速度和冰块面积等海冰参数进行提取。采用该海冰雷达监测系统和数字图像处理软件,在2011-2012年冬季对该海域的海冰运动规律进行了全冰期的连续监测,在此基础上重点对海冰速度的雷达图像监测结果进行了分析,讨论了海冰速度场分布以及连续48 h的变化过程。以上结果为海冰的生消运移规律研究和油气作业区的海冰管理工作提供了可靠的现场监测数据。对海冰雷达现场监测及数字图像处理中的问题及改进方法进行了讨论。
    Abstract: Sea ice brings negative influences on offshore structures, nautical transportation and aquaculture in the Liaodong Gulf, where the sea ice condition is most severe in the Bohai Sea. The accurate, successive and long-periodic real time observation of sea ice parameters is necessary for the investigation of sea ice thermodynamics and dynamics, and also guarantees the safety in an oil/gas exploitation. A sea ice radar observation system is set up on the JZ20-2 oil/gas platform according to the sea ice characteristics and engineering requirement of the Liaodong Gulf. A digital image processing and analyzing system for sea ice radar observation data is developed to extract sea ice concentration, ice velocity and ice floe area. The sea ice conditions in the JZ20-2 oil field are monitored and analyzed with this radar observation system and digital image processing software during the winter of 2011-2012. Especially, the field distribution of the sea ice velocity and the mean ice velocity in 48 h are analyzed. The results provide real time sea ice information for the sea ice management in the oil/gas field, and the investigation of sea ice drifting. Some open problems and improvements for the sea-ice radar observation and the digital image processing system are discussed.
