摘　　要：以胜利埕岛油田海底长输天然气管道为例 ,较系统介绍了海底管道勘测方法 ,根据调查资料成果 ,划分了调查区地貌特征类型 ,给出了天然气埋设探测状况 ,总结了水深变化规律和区域水深差异特点 ,分析了水深变化、海底冲蚀和地质作用等因素对海底管道可能造成的影响 ,为管道安全生产。The survey methods of submarine pipeline are systematically introduced by taking the Chengdao oil field submarine gas pipeline as an example. Based on the observed data, the geomorphologic characteristics in the survey area are classified, the surveys on the gas pipeline burial conditions are overviewed, the water depth variabilities and the local water depth differential features are summarized, and the potential effects of environmental affecting factors on submarine pipeline are analysed, which provides basis for pipeline safe operation, disaster prediction and assessment and offshore engineering survey and study in the future.
