摘　　要：全面回顾了大庆油田特高含水期开发技术的创新发展历程,系统总结了特高含水期储层精细描述、剩余油精细描述、长垣水驱开发调整、长垣外围油田开发、复杂断块油藏开发、聚合物驱、三元复合驱和难采储量有效动用等油田开发技术。在客观分析大庆油田振兴发展需求和特高含水后期面临矛盾问题的基础上,紧密结合油田开发技术现状,指明了油田开发核心技术主攻方向。围绕探索建立新一代提高采收率核心技术体系,对特高含水后期油气开发战略、油藏精细描述、长垣水驱精准开发、大幅度提高采收率和外围油田开发调整等技术的未来发展进行了展望。The processes of the technical innovation and development were reviewed in a whole for the development of Daqing Oilfield at ultra-high watercut stage,the following developing techniques were summarized systematically:fine reservoir characterization,fine description of the remained oil,water-flooding development adjustments of Daqing Placanticline,development of Placanticline periphery oilfields,development of the complex fault-block reservoirs,polymer flooding,ASP flooding and effective development of the difficult-to-produce reserves and so on.Based on the objective analyses of the re-energizing and developing requirements of Daqing Oilfield and the facing contradictions and problems at the late stage of the ultra-high watercut,with the help of close integration with the current status of the oilfield developing techniques,the main tackled research orientations of the core techniques of the oilfield development were made clear.Around the exploration of establishing the new-era EOR core techniques,the following prospects of the future development were conducted for the late period of the ultra-high watercut,including the oil-gas development strategy,fine reservoir characterization,precise development of the water flooding in the Placanticline,great enhancement of the oil recovery,developing and adjusting techniques for the peripheral oilfields and so on.
