摘　　要：大港油田埕海一区馆陶组为构造砂岩底水油藏,储层发育受辫状河道控制,内部发育多条小断层和隔层。开发过程中底水锥进严重,使得井间分布大量剩余油。通过油藏精细地质模型和油藏数值模拟,准确描述剩余油的分布规律,部署了调整井,预测了开发效果。The Guantao formation in district 1 of Dagang Chenghai oilfield is a ＂high viscosity,heavy weight,low solidification＂ structural sandstone reservoir,the development of which is controlled by the braided river,and contains a number of small faults and compartments internally.Many years＇ exploration and development makes the regional distribution of remaining oil fragmentation and marginalization,the accurate recognization of the distribution rule of it is essential to assess reservoir reasonably and adjust potential targets.Through the building of geological model and numerical model,the rule of the remaining oil is analyzed and achieved a good result,provided a reliable geological foundation for further well spacing and tapping.
