摘　　要：以水驱储量动用程度作为油田开发的重要参考指标,提出了准确合理地计算基于油井单元的水驱储量动用程度的方法。基于当前L油田注采井网,以油井与油井、油井与水井、定向井与水平井流线边界为划分依据,将L油田划分为27个基本开发单元,完成单元静态井控储量计算,应用各油井单元静态、动态数据和乙型水驱曲线完成动用程度计算。结果表明,受井网完善度、水驱方向的影响,各单元动用程度存在较大差异,结合井网注采受效分析确定了高部位油井转注、中部位细分层系、低部分补充注水井的下一步综合调整方向,为油田的精细化认识与下一步开发优化提供了重要借鉴。The degree of water-flooding reserve production is an important reference index for oilfield development.Based on oil well unit,this paper proposes the accurate and reasonable calculating method for water-flooding reserve production degree.Based on current injection-production well pattern,the L Oilfield is divided into 27 basic development units according to the principles of dividing boundaries between oil wells and oil wells,oil wells and water wells,directional wells and horizontal wells.The calculation of static well-controlled reserves of the units is completed,and each oil well is combined.The static and dynamic data of the units are calculated by B-type water drive curve method.The results show that the production levels of each unit affected by well pattern perfection and water flooding effect are quite different.Combined with the current well pattern injection-production analysis,it is determined that the main oil wells in the high part are transferred to injection,the middle part is mainly subdivided into layers,and the low part is mainly about the next adjustment direction of supplementary water injection well,which provides important references for refined understanding and following development optimization in the oilfield.
