摘　　要：复杂断块油藏开发后期剩余油分散而难以识别 ,且其分布受多种因素的控制 ,在濮城油田沙三上油藏根据纵向上 3 2个流动单元为对象的剩余油精细描述 ,提出了 3类剩余油潜力 :1已动用油层 ,即断层与微构造控制、注采井网不完善、层间非均质性、平面低渗透相带、注采滞留带等因素形成的剩余油 ;2新层 ,即以往未发现的低电阻油层和新发现的油砂体 ;3滚动扩边 ,在潜力富集区钻新井、更新井 ,重组层系、井网 ,改变渗流方向和间歇注水 ,并对潜力区配套实施补层、提液、压裂、近解远调等措施。提高了该油藏在高含水期的开发水平。Remained oil of complicated block reservoir is detracted and difficult to identify in the late-exploitation time ,its distribution is controlled by multi-factor,three kind potential areas of remaining oil are put forward by means of reservoir fine description whith takes 32 flowing cells as study targets.Producing oil formation is the frist kind,in which the remained oil are dominated by fault and micro-struction,imperfect injection and production pattern,interval heterogeneity,low permeable zone on plane, the stagnant area of injection and production and so on.The second is new-strata,involving the low-resistively oil formation not being found in the past and the oil sand being found freshly.The third is progressive development area. the new and renewal wells are drilled in potential enriched areas,driving types of non-dominating oil formation are changed,layer series and well parttern are regrouped,the fluid direction is changed and cycle injection is adoped,and at the same time,to potential areas,new layers are perforated,liquid productions are increased,fracturing and sand prevention,re-perforation,and deeply profile controlling technologies and so on are applied. the development benetfits and levels of high water-cut in this reservoir are improved.
