摘　　要：南海东部A油田为典型的海相砂岩油田,从1995年投产至今,大部分油藏已进入特高含水、特高采出程度的“双特高”阶段,油田整体进入“双特高”开发后期。为了进一步挖潜该油田的剩余油,延缓油田产量递减趋势,通过分析历史114口调整井实际生产动态,研究了该油田双特高开发后期剩余油的分布规律,分析了后期调整井主要挖潜方向,利用油藏动态分析和油藏数值模拟方法分析了A油田调整井合理初期工作制度范围。研究成果指导后续调整井工作制度优化,生产效果得到改善。Oilfield A in the East of the South China Sea is a typical Marine sandstone oilfield.Since 1995,most of the oil reservoirs have entered the“double extra-high”stage of ultra-high water cut and ultra-high recovery degree.At present,the A oilfield in the East of the South China Sea has entered the late stage of high water cut development.In order to further tap the remaining oil of the oilfield and slow down the production decline of the oilfield,the production dynamics of 114 historical adjustment wells were analyzed,the distribution of remaining oil in the double ultra-high water cut period of the oilfield is studied,the main potential exploitation direction of the adjustment wells in the late period of high water cut is analyzed,and the reasonable initial working system range of the adjustment wells in the oilfield A group is analyzed by means of reservoir dynamic analysis and reservoir numerical simulation,and the working system optimization of the subsequent adjustment wells is guided.
