我国在南海海域开展了多年的天然气水合物的调查工作,主要采用单缆单源的准三维多道地震勘探方法,取得了较好的效果。针对准三维多道地震中的羽角问题,我们根据实际情况,在“潮汐与羽角预测技术”的基础上,使用横向水鸟来控制电缆羽角,很好地解决了准三维多道地震作业中的面元覆盖问题,保证了资料质量,提高了作业效率。 China has conducted many years of investigation of natural gas hydrates in the South China Sea. The main single-cable single-source multi-channel seismic exploration has achieved good results. According to the actual situation, based on the “tide and feather angle prediction technology”, we use horizontal waterfowl to control the cable feather angle and solve the problem of quasi-three-dimensional multi-channel seismic operation The coverage of the briquette problem, to ensure the quality of data, improve operational efficiency.
