图像声纳在油气田气体泄漏监测中的应用

Application of Image Sonar in Gas Leakage Monitoring in Oil and Gas Fields

中国是海洋大国,这片蓝色疆土中有着丰富的资源,因此开发利用海洋资源对我国的可持续发展有着重大的意义。对海洋的探索已不仅仅只限于军事目的,也转向了民用目的,如海底资源开发、石油勘探、自动绘制海底地形地貌图等。油气田是海底开采石油、运输石油的大型民用项目,油气管道是在海底连续输送大量油气物质的密闭型联通容器。油气管道所输送的油气为有害的易燃易爆物质,一旦管道发生泄漏或断裂,会对其周围的环境和人员产生严重的后果,所以对油气田气体泄漏的监测成为一项关键技术,能够及时避免事故的发生。对处于深海的水下结构来说,监测气体泄漏的首选方法是水下声学监测,论文主要研究图像声纳在油气田气体泄漏监测中的应用。

China is a big sea country.This blue territory has a wealth of resources.Therefore,the development and utilization of marine resources are of great significance to China's sustainable development.The exploration of the oceans has not only been limited to military purposes and also turned to civilian purposes.Such as the development of seabed resources,oil exploration,automatic mapping submarine topography and so on.Oil and gas fields are large civilian projects for drilling oil and transporting oil under the sea.Oil and gas pipelines are closed-type containers that continuously deliver a large amount of oil and gas on the seabed.The oil and gas transported by the oil and gas pipeline are harmful inflammable and explosive substances.Once the pipeline leaks or breaks,it will have serious consequences for the environment and personnel around it.Therefore,the monitoring of gas leakage in oil and gas fields has become a key technology,which can promptly avoid the occurrence of accidents.For underwater structures in the deep ocean,the preferred method of monitoring gas leaks is underwater acoustic monitoring.This thesis mainly studies the application of image sonar in gas leakage monitoring in oil and gas fields.
