摘　　要：为了海底输油气管线运行安全,避免潜在的灾害性因素的发生,对广东沿海一段海底输油气管线状态进行检测,采用浅层剖面测量、侧扫声呐测量和多波束测量手段对海底油气管线路由区域进行了勘测,勘测结果表明检测区域海底油气管线没有裸露和悬空,埋藏状态良好,管线周边地层较稳定,根据侧扫声呐图像和多波束测深图像,发现在管线路由区海底存在影响海底油气管道安全的因素,管线路由区海底拖锚等痕迹较多,并且在距离管线大约1 000m处有一个较大人工采砂坑存在。In order to guarantee the safety of the submarine oil and gas pipelines and avoid the occurrence of the potential catastrophic factors, the states of the submarine oil and gas pipelines in one section of Guangdong coastal area are inspected. The routing area of sub-marine oil and gas pipeline receives the surveys with the methods of shallow profiling, side -scan sonar and multi - beam measurement. The survey results indicate that the subma-rine oil and gas pipelines in the survey area are not exposed or suspended with a good em-bedding state and the surrounding strata of the pipeline are stable. Based on the images of side-scan sonar and multi - beam sounding, this paper finds that there are some factors af-fecting the safety of this submarine oil and gas pipeline on the seabed of the routing area, including multiple traces of dragging anchor, and one large artificial sandpit located at ap-proximately 1 000 m from the pipeline.
