摘　　要：渤海海域BZ油田是典型的浅水三角洲复杂断块油田,主要发育水下分流河道砂体,具有“一砂一藏”的特征,开发过程中存在河道窄、厚度薄、单砂体储量规模小、油气水分布复杂等挑战。针对以上问题,依据钻井、测井、录井、地震及生产动态等资料,通过开展油田内挖外扩持续稳产挖潜研究,形成基于高分辨率地震资料的储层精细描述、气顶油藏双高阶段调整挖潜、基于目标砂体优选的滚动评价挖潜技术体系,助力实现储量和产量接替,有效保证了油田持续高效开发。The BZ oilfield in the Bohai Sea is a typical shallow-water delta complex fault-block oilfield.It mainly developed underwater distributary channel sand bodies with the characteristics of"one sand and one reservoir".In the development process,there are challenges such as narrow channels,thin thickness,small reserve size of single sand bodies,and complicated distribution of oil,gas and water.In view of the above problems,based on the data of drilling,logging,logging,seismic and production dynamics,through the continuous research on internal excavation and external expansion of oil fields.The technical system of reservoir fine description based on high resolution seismic data,double high stage adjustment and potential tapping of gas cap reservoir,and rolling evaluation and potential tapping based on target sand body optimization are formed.It helps to realize the replacement of reserves and production,and effectively ensures the continuous and efficient development of the oilfield.
