摘　　要：近年来,深水成为全球油气勘探开发热点领域。与陆上或浅海油田开发相比,深水油田开发具有投资规模大、建产周期长、开发成本高、地质风险高、技术复杂等特点,如何实现高效开发是深水油田普遍面对的重大问题与挑战。以西非下刚果盆地某大型深水油田群为例,剖析并总结了该油田群高速高效开发的主要做法及开发效果。研究表明,该油田群采取联合开发、少井高产的开发策略,采用稀疏井网条件下多点地质统计地质建模、油藏-井筒-海底系统一体化优化、4D地震技术等,实现了油田群高速高效开发,研究成果对我国深水油田开发具有一定借鉴和启示意义。In recent years,deepwater is increasingly becoming the hot region for global oil and gas exploration and development.Compared with onshore or shallow-water oilfields,deep-water oilfields development usually has characteristics such as expensive investigation,long construction period,high geological risk,and demanding complex techniques,etc.It is a great challenge to perform high-efficiency development for deep-water oilfields.This paper took a certain large deep-water oilfields group in lower Congo Basin as an example,analysed and summarized the main practices and effects of high-efficiency methods used in development.The results show that,using methods such as co-development and high-productivity with less wells,combining with techniques including multi-points geo-statistics modelling under sparse well pattern,integrated optimization of reservoir-wellbore-subsea system,and 4D seismic,high-efficiency development of deep-water oilfields is achievable.The research results have certain reference and enlightenment significance for the development of deep-water oilfields in China.
