摘　　要：随着油田开发主体技术的不断进步,开采多年的老油田得以持续有效深化开发,原来认为难以开采的复杂油田得以有效开发动用,大幅度提高了资源的利用率和石油的保障供给能力。通过系统总结中国中高渗高含水、低渗透、稠油、复杂断块、特殊岩性等油田近10年来开发主体技术取得的新进展,特别是在提高采收率技术方面取得的国际领先成就,分析了各类油田开发面临的问题与挑战,提出了"配套应用、攻关试验、超前储备"三代主体技术滚动接替的发展路线和技术方向。建议的重点研究工作有:(1)进一步完善老油田精细注水和化学驱、化学驱后提高采收率、低渗油藏注气等理论技术的研发和矿场试验;(2)加强纳米智能驱、原位改质、同井注采等颠覆性技术的基础理论方法研究;(3)超前储备适应低油价、新领域(深海、深层、非常规等)、高难度(四次采油、超低渗三次采油等)条件下提高采收率的新技术。通过开发技术及油藏管理的不断创新,推动油田开发主体技术的研发换代和有序接替,实现油田开发的可持续发展。As technologies advance in oilfield development, mature oilfields are able to keep sustainable production and complex oilfields difficult to produce in the past are put into production efficiently. In this work, new progresses of main development technologies for medium-high permeability and high water cut, low permeability, heavy oil, complex faulted block and special lithology reservoirs in the past decade, especially those international achievements made in enhanced oil recovery, were summarized, the key problems and major challenges that different oilfields are facing were analyzed, and the development route and direction of three-generation technologies were proposed as “mature technology in industrialized application, key technology in pilot test and innovative technology for backup”. The key research contents should focus on： （1） Fine water flooding and chemical flooding for mature oilfields, improving oil recovery after chemical flooding, and gas flooding for low permeability reservoirs must be researched and tested in field further. （2） Study on subversive technologies like nanometer smart flooding, in-situ upgrading and injection and production through the same well should be strengthened. （3） EOR technologies for low oil price, new fields （deep sea, deep layer, unconventional reservoirs etc.） and highly difficult conditions （the quaternary recovery after chemical flooding, tertiary recovery in ultra-low permeability reservoirs） should be stocked up in advance. The development cost must be lowered significantly through constant innovation in technology and reservoir management to realize sustainable development of oilfields.
