海底管道所处环境复杂多变，在外力或内因的作用下可导致管道断裂，管道断裂具有泄漏位置定位困难、经济损失大和环境污染严重等特点。此文通过实例使用地球物理方法对海底输气管道泄漏位置调查进行了研究，综合分析了海水水体异常、海底地貌异常、地层剖面异常等特征。研究结果表明，地球物理方法能够准确确定海底输气管道泄漏点位置。该成果可为今后海底管道断裂位置调查提供重要指导作用。

The environment of submarine pipelines is complex and changeable. The pipelines may fracture under the action of external forces or internal factors. Fractures of the Pipelines have the characteristics of difficult location, economic losses and serious environmental pollution. This paper researched the application of geophysical methods in the investigation of leakage points of submarine gas pipelines through an example. The results show that the location of leakage points of submarine gas pipelines can be located accurately by analyzing the abnormal characteristics of the seawater, submarine geomorphology and stratum profile. It can provide important guidance for the investigation of the fracture points of submarine pipelines in the future.
