复杂地质条件下海底管道路由选择技术

A study of subsea pipeline route selection under complex seabed geological characteristics

海底管道是海洋油气田开发的重要组成部分,随着我国海洋油气田的大规模开采,海底管道在未来海洋石油工业链条中的纽带作用将越加突出。首先介绍海底管道路由选择面临的海床地质特征:海床不平整、冲刷、断层、液化等,其次介绍基于复杂地质条件海底管道路由选择流程和接受标准,最终阐述海底管道路由选择的设计方法。本文的研究成果既是对中国海区已运行项目的总结,也为我国南海深水油气田开发及拓展国外市场提供参考。

Subsea pipeline is one of the most important components for petroleum development and the function will be more markedly important in the future. Firstly,the paper describes the seabed geological characteristic problem for route selectionof subsea pipeline,such as uneven seabed,scour,fault,liquefying and so on. Secondly,presents the design process and accept code for subsea pipeline route selection. Finally,put forward the methods subsea pipeline route selection. The conclusion of this paper is of value for the summary of existing subsea pipeline project and is also useful for South China Sea and overseas petroleum development.
