摘　　要：随着中国海洋石油工业的快速发展,海上中深层油气藏已成为油气资源最主要的接替区和增储上产的主战场。完井作为海上中深层油气田开发的关键环节,直接影响到油气井的生产能力和经济寿命,甚至关系到整个油气藏能否得到有效的开发。海上中深层油气藏存在岩性变化大、温度高、压力高等储层特点,导致油气井存在单井产能低、完井作业复杂、工期长、智能化水平不高等难题。总结了中国海油在中深层油气田注采一体化、增产生产一体化、射孔联作、增产改造、智能完井等方面取得的关键技术成果,分析了存在的问题与挑战,并在此基础上对海上中深层油气田完井技术的发展趋势进行了展望,以期为推动海上油田增储上产与高效开发提供借鉴。With the rapid development of China’s offshore oil industry,offshore middle-to-deep oil and gas reservoirs have become the most important replacement areas for oil and gas resources and the main battlefield for increasing reserves and production.Well completion is a crucial aspect of developing offshore middle-to-deep oil and gas fields,which directly impacts the production capacity and economic lifespan of oil and gas wells and can even affect the effective development of the entire oil and gas reservoir.The offshore middle-to-deep oil and gas reservoirs have the characteristics of large lithology changes,high temperature,and high pressure,which lead to the problems of low productivity per oil and gas well,complicated well completion operations,long construction period,and low intelligence level.The key technical achievements made by CNOOC in integrating injection and production,stimulation and production,perforation operations,as well as production enhancement and intelligent completion in the middle-to-deep oil and gas fields were summarized,and the existing challenges were analyzed.On this basis,the development trend of well completion technologies for offshore middle-to-deep oil and gas fields was prospected,so as to provide a reference for promoting offshore oilfields to increase reserves and production and efficient development.
