国外深水油田高效开发关键策略与技术

Key Strategy and Technology for Efficient Development of Foreign Deepwater Oilfields

深水油田勘探开发在国外已取得了重要的成功,国内还处于起步阶段,开发经验及相关的研究和报道都比较少。基于此,在调研众多实例的基础上,从油藏特征、开发策略、开发方式、油田监测与管理方面对国外深水油田开发进行了研究与剖析,认为国外深水油田之所以能够实现高效开发,重力流沉积油藏优越的储层和流体条件是基础,少井高产和保持能量开发是关键,智能油田监测与管理是保障,观念和技术创新是根本原因。这些认识能够为我国南海东部深水油田的开发带来启示与帮助:贯彻少井高产开发策略,相比浅水油田,南海东部深水油田可以提高单井产量和单井控制储量;重视智能油田监测与管理等新技术,以提高监测与管理水平和效率。同样,当面对复杂、特种油气藏开发时,要敢于观念转变、善于技术创新或利用新技术,大胆实践,才能更有效地攻克开发难题。

Exploration and development of deepwater oilfields has achieved significant success at abroad,but is still in its infancy stage in the domestic with few development experience,related research and report.So, based on investigation and research of a lot of cases ,the development of the foreign deepwater oilfields was studied and analyzed at the aspects of reservoir characteristics, development strategy, development mode, oilfield monitoring and management.A conclusion was drawn that good reservoir and fluid condition of the oil reser- voir with gravity flow deposit is the foundation,less wells,high production and development with constant pressure are the key ,intelligent oilfield monitoring and management are the guarantee ,and idea and technical innovation are the primary reason of the efficient development in the foreign deepwater oilfields.These findings can bring inspiration and help to develop the deepwater oilfields in eastern South China Sea：to insist the strategy of less wells and high production ,oil production and probable reserves of single well may be en- hanced compared with the shallow water oilfield;to attach the importance to the application of new technolo- gy such as intelligent oilfield monitoring and management, level and efficiency of the monitoring and manage- ment may be improved.At the same time,we should dare to change the idea,carry out technical innovation or make use of new technology when in face of complex and special reservoirs.
