【摘要】 春光油田是以沙湾组为主力含油层的浅层优质高效油田,在矿场实践过程中逐步形成了薄砂体滚动勘探、勘探开发一体化、开发动态监控技术、单井油嘴系数估产技术及新的油藏经营管理模式等鲜明的特色技术。针对岩性油藏的隐蔽特点,形成了以地震属性特征直接判断油层的技术;针对边水活跃的特点,建立了油藏精细地质模型,形成了以数值模拟为核心的油藏-井筒-地面一体化动态监控技术;立足实际,形成以单砂体成为独立油藏管理单元、管理扁平化、用工属地化、制度文本化为主要内容的实用油藏管理模式。春光油田开发5 a以来,产量稳步上升,保持自喷开采,边水水线缓慢、均匀推进,含水率仅为2%,采油速度保持在5%以上,采收率为47%。更多还原

【Abstract】 Chunguang oilfield mainly produces from the Shawan formation which is a shallow,efficient and high-quality reservoir.In the process of field practice,distinctive technology has been developed including progressive exploration for thin sand bodies,integrated exploration and development,development performance monitoring,production estimation by single well bean coefficient,and reservoir management model for western Shengli oilfield.Lithologic deposits have subtle feature and are identified directly by using seismic attributes.Regarding active edge water,a fine reservoir geological model is established to realize integrated dynamic monitoring of reservoir-wellbore-surface through numerical simulation.A practical reservoir management model has been formed on the basis of single sand.In the past five years since the Chunguang oilfield was put into production,the production has increased steadily by maintaining flowing production;edge water propagates slowly and evenly;water cut is only 2%;oil recovery rate remains over 5%;and the recovery factor is 47%.更多还原
