南海东南部深水气田隔水管—井口系统力学分析
Mechanical analysis of the riser-wellhead system for deepwater gas fields in the southeastern South China Sea
摘要
Abstract
The riser-wellhead system is a significant equipment for deepwater drilling and serves as a key factor affecting the safety of deepwater drilling operation.Influenced by offshore wind,waves,currents,and the drift of floating drilling platforms,the deepwater drilling riser-wellhead system is susceptible to risks such as mechanical strength damage and structural integrity failure.In order to improve the operational safety in the southeast gas field in the South China Sea,data research,theoretical studies,and computational analyses are conducted.Through strength analysis,weakness analysis,drift analysis and fatigue analysis,key mechanical analysis technologies for deepwater riser-wellhead system have been developed.These advancements have effectively guided drilling engineering design,ensured on-site operational safety,and accumulated valuable technical experience for the exploration and development of deepwater oil and gas fields in China.关键词
