西非深水油气田典型开发模式分析

Analysis of Typical Development Modes for Deepwater Oil and Gas Fields in West Africa

针对西非现有主要深水油气田的开发状况和工程模式,统计和整理出西非主要深水油气田的主平台类型和典型的5大类开发模式。着重分析了各开发模式在西非深水油气田的实现形式及其主要特点,并根据西非深水海域现有的深水平台,探讨了环境、水深、油藏、政策等主要控制因素对西非深水油气田开发模式的影响,提出海上浮式平台、水下生产系统和外输方式基本设计的选择关键要点。为高效开发西非深水油气田提供了一定的参考依据,并对自主开发中国南海深水油气田具有一定的现实意义。

By comprehensively investigating the development conditions and engineering modes,a statistical analysis of various platforms applied in the deepwater is performed and five typical development modes are made in West Africa.Priority is given to the analysis of the implementation of the development modes in West Africa and their main characteristics.Based on the adaptability of the existing deepwater platforms used in West Africa,the impact of the major controlling factors on the deepwater development mode in West Africa is discussed,such as the environment,water depth,reservoir,policies,etc.And the key points of the basic design and choice of the offshore floating platform,subsea production systems and export system are proposed.This paper provides important reference frames for Chinese oil companies to efficiently develop deepwater oil/gas fields in West Africa,and is also of practical significance for China to develop deepwater oil/gas in South China Sea independently.
