摘    要:夹层抑制底水锥进效果良好,但尚未开展其定量评价的研究.针对该问题提出了根据夹层参数,将其定量评价为无夹层、渗滤型夹层、小范围不渗透夹层和大范围不渗透夹层4种分布模式.无夹层模式底水快速锥进,远离井筒周围分布大量剩余油,可通过完善井网提高动用程度;渗滤型夹层底水被转化为次生边水和次生底水,开发效果较好,剩余油分布较少;小范围不渗透夹层底水转化为次生边水,极易在夹层底部形成"屋檐油",顶部形成"屋顶油",可作为后期挖潜的方向;大范围不渗透夹层完全抑制底水运动,上下邻层均可形成大量剩余油,是油田开发后期挖潜的重点.

关 键 词:夹层模式  底水油藏  油水运动  屋檐油  屋顶油

Abstract:The inter-layer can constraint the coning of bottom water.But there is no quantitative method for evaluating the control effect of inter-layers on the migration of oil and water in bottom-water reservoirs.For this reason,it is put forward that the distribution modes of the inter-layers in bottom-water reservoirs are divided into 4 types according to some parameters of such as area,thickness,permeability,shale content etc.:inter-layer free distribution mode,permeable inter-layer distribution mode,impermeable...
Keywords:inter-layer mode  bottom water reservoir  oil-water migration  eaves oil  roof oil
