摘　　要：台兴油田阜三段(Ef3)为三角洲沉积,主要发育水下分支河道、河口坝、远砂坝(席状砂)和分支间湾4个微相,动态资料、油藏描述及数模研究表明:平面上河道砂微相油层水淹严重,剩余油仅分布在断层、油藏边角及微构造高点,河口坝及远砂坝微相的二、三类储层注采不完善,剩余油潜力仍较大;纵向上,主力油层剩余油集中在正韵律上部中低渗区,非主力层储层物性较差,动用程度低,剩余油潜力较大。根据本区剩余油分布的特点,采取了加密井网、细分层系、零散调整等挖掘剩余油的对策与建议,为油田综合调整方案的制定提供了依据。As a set of deltaic sediments,Member Fu 3（Ef^3） in Taixing oilfield is developed mainly in four microfacies,i.e.distributary channel,mouth bar,distal bar （sheet sand） and meander among branches.The performance data,reservoir description and numerical simulation have indicated that the distributary channel sand reservoir is severely waterfiooded in area,with its remaining oil only in faults,corners and micro-highs,and that the type Ⅱ and Ⅲ reservoirs of mouth bar and distal bar are not perfect in injection and production, with a greater potential of remaining oil.Vertically ,remaining oil in the major reservoirs is concentrated on a middle-low permeability zone in their upper positive rhythms,and the minor reservoirs arc poorer in petrophysical property and low in producing sweep,with a quite great potential of remaining oil.From these features of remaining oil ,several measures are adopted to tap its potential ,such as intilled well pattern,reser- voir subdivision and stray adjustmemt.
