摘　　要：随着海洋油气资源开发进程加快,水下溢油污染已成为海洋环境最主要的威胁之一。水下溢油发生后,溢出的油气在水体中形成羽流,但油气羽流的声散射特性尚不明确。本文通过船载多波束声呐开展了水池油气泄漏模拟实验,探讨了流量对声学反向散射强度的影响,论述了油气羽流的声学散射特性,以期为水下油气泄漏探测提供参考。With the rapid development of offshore oil and gas resources,underwater oil spill has become one of the most important threats to marine environment.After an underwater oil spill occurs,oil and gas spill are released into the water,forming a plume.However,the acoustic scattering characteristics of the oil and gas plume are not yet fully understood.This paper conducts simulation experiments of oil and gas leakage in a pool by MBES.The study examines the influence of flow on backscattering intensity and discusses the acoustic scattering characteristics of oil and gas plumes.The findings of this research provide valuable insights for underwater oil and gas leakage detection.
