摘　　要：针对大庆油田海外多种类型油藏开发面临的挑战和技术需求,梳理近5 a大庆油田海外油藏开发形成的技术成果,系统总结已形成的适合海外多种类型油藏的特色高效开发技术。大庆油田经过近5 a来的海外油藏开发实践,将成熟油藏开发技术与海外油藏特征相结合,依靠已有优势技术创新驱动,形成了3项海外特色开发技术:一是以油藏精细描述和“优、分、调”立体开发调整为核心的复杂断块砂岩油藏有效开发技术;二是以化学剂研制及性能评价和化学驱试验方案优化为核心的高温高盐砂岩油藏化学驱提高采收率配套技术;三是以碳酸盐岩油藏测井精细评价、高渗透层识别和注水开发为核心的孔隙型碳酸盐岩油藏开发配套技术。海外油藏开发实践证明,大庆油田针对海外多类型油藏的高效开发配套技术,有力支撑了中国石油权益区块的高效开发,提升了大庆油田的国际知名度和影响力。In view of the challenges and technical requirements faced by the development of different types of overseas reservoirs of Daqing Oilfield,technical achievements of overseas reservoir development of Daqing Oilfield in the past 5 years are reviewed,systematically summarizing developed distinguished efficient technologies suitable for different types of overseas reservoirs.For nearly 5 years of overseas reservoir development practice,Daqing Oilfield Company combined mature reservoir development techniques with overseas reservoir characteristics,based on existing advantageous techniques to drive innovation,and formed 3 overseas distinguished development technologies.The first is effective development technology for complex fault-block reservoirs,with core techniques of fine reservoir description and 3D development adjustment of“optimization,division and adjustment”as.The second is chemical flooding technology to enhance oil recovery in high-temperature and high-salinity sandstone reservoirs,with core techniques of chemical agent development and performance evaluation and chemical flooding experimental schemes optimization.The third is development technology for porous carbonate reservoirs,with core techniques of fine logging evaluation of carbonate reservoirs,identification of high-permeability layers and waterflooding development.Development practice of overseas reservoirs proves that Daqing Oilfield’s efficient development techniques for different types of overseas reservoirs provide supporting for efficient development of CNPC’s equity blocks and enhance international visibility and influence of Daqing Oilfield.
