深水井控成功实践与技术分析
Successful practices and technical analysis of deepwater well control
摘要
Abstract
The deepwater drilling belongs to a high-risk, high-investment and high-technology industry, and the deepwater well control is the core issue to the deepwater drilling. The offshore deepwater well control is faced with lots of dififculties and challenges, such as dififcult well kick monitoring, weak stratum bearing capacity, small well kick margin, large friction resistance of choked lfow pipeline, stratum breath effect, gas hydrate and trapped gas. With successful practices of well killing of a deepwater well implemented by CNOOC , in West Africa as an example, via the analysis of well control operation process, this Paper researches and explores the deepwater well control technology and provides reference to the well control operation of deepwater drilling.关键词
