摘　　要：苏丹1/2/4区块状强底水油藏经过8年的高速高效开发,已经进入高含水开采期,油田产量递减趋势明显,稳产难度增大。针对这种情况,通过油藏地质综合研究、开发动态分析和精细油藏数值模拟研究,确定出油藏中剩余油纵向上主要集中在油层顶部,平面上主要分布在井网稀疏区、局部构造高部位和断层附近。在此基础上,利用加密井、水平井、提液、卡堵水、低效井侧钻以及合理射孔等相适应的开发调整技术与策略,现场应用取得了很好的效果。在油田开发过程中形成了一套块状强底水油藏高效开发调整技术。After 8 yearl,high speed and high efficiency exploitation in Block 1/2/4 Sudan,it has entered high water cut development,and there will be more complex problems to be faced,such as the obvious decline of oil field production and more difficulty in stabilizing production.According to this situation,comprehensive research on reservoir geology,dynamic analysis on development performance and fine reservoir numerical simulation is conducted to determine that remaining oil mainly distributes vertically on the top of the reservoir,and horizontally in sparse pattern areas,high positions of local structures and near faults.Comprehensive adjustment strategies and measures,such as well pattern infilling,horizontal well,lifting with electric submersible pump,water plugging,reperforating and sidetrack low effect well etc.are implemented on this basis,and oilfield application acquires preferable effectiveness.A whole set of high efficiency development technology for strong bottom water driving block-shaped reservoirs is formed.
